Same Width, 2.6 to 3.7 Cu Ft Inside the Best 24 Inch Gas Stove

1. Cosmo Haven Collection 24-Inch 3.7 Cu Ft 4-Burner Gas Range with Convection, COS-EPGR244 — Best Overall

The most oven per inch of any 24-inch listing without a conflict, and the only one that itemises every burner and both oven burners.

Key Specifications

Why We Recommend It

This is the biggest oven in 24 inches that nothing on its own listing contradicts. The title says “3.7 cu ft” and the second bullet repeats it: “Spacious 3.7 cubic foot oven features a fan to distribute heat evenly around the food and eliminate cold spots in the oven cavity.” Spread across 24 inches, that is about 0.154 cu ft per inch by our arithmetic, the top of the page. Against the 2.6 cu ft in either Avanti it is 1.1 cu ft more oven, or about 42% more, in the same nominal width. The KoolMore claims the same 3.7 in its title but gives 3.46 in a bullet; the Haven gives one number everywhere.

It is the only 24-inch range that tells you what every burner does. “An 18,000 BTU Burner, 12,000 BTU Burner, 9,000 BTU Burner, and 3,500 BTU Burner.” That adds up to 42,500 BTU across the cooktop, by our arithmetic, and the spread matters more than the total. 18,000 BTU is twice the 9,000 BTU of each burner on the white Avanti, which is the difference between a large pot of pasta water coming up quickly and coming up eventually. At the other end, 3,500 BTU is the lowest simmer figure printed by any 24-inch listing here. The oven is itemised too: a “12,000 BTU Bake Burner and 10,000 BTU Broil Burner”, which confirms a separate broil burner rather than leaving you to guess.

The gas setup is stated plainly, and so is what is missing. The last bullet reads “Natural Gas; Liquid Propane Conversion Kit sold separately”. If your home runs on a natural gas main, that is the clearest statement among the 24-inch ranges. If you run on propane from a tank, budget for the kit and for a qualified, licensed gas installer to fit it, because converting a range means changing orifices and setting the regulator, and that work belongs to a professional following the manual and local code.

It is the only listing here near standard counter height. The bullet gives “23.88″ (W) x 27.6″ (D) x 36″ (H)”; the spec table says 36.8 inches tall. Every other range that gives a height lists between 40.25 and 42.125 inches. It is also the deepest stated range on the page at 27.6 inches and the heaviest at 146.6 pounds, so check the depth of your counter run and the path from the door to the kitchen before you order.

Safety features are listed, a safety listing is not. The listing describes “an oven cavity cooling ventilation system for safe heat dissipation, overheating protection, triple-thick oven glass, and a cool-to-touch oven handle”. It does not name a CSA or ETL certification, where the Avantis, Magnificent Chefs and KoolMore all do; ask the seller to confirm before purchase. Ignition type is not stated either.

What to weigh. It is sold by Amazon.com, ranks #1,352 overall and #13 in Freestanding Ranges, and was flagged as scarce stock at capture. The warranty is one year limited. It is the most expensive 24-inch range in this roundup, and what the extra buys is measurable from the listing: 1.1 cu ft more oven than an Avanti, convection, an 18,000 BTU burner and a printed figure for every flame in the box.

Best for: A natural gas kitchen with a 24-inch slot that wants the largest oven and the strongest burner the listings can document.

2. KoolMore 24-Inch 4-Burner Slide-In Gas Range, KM-SGR24-SS — Best Slide-In

The only slide-in here, with the highest stated cooktop total, and two different oven sizes on one listing.

Key Specifications

Why We Recommend It

The listing gives two oven sizes, and they are a quarter of a cubic foot apart. The title says “3.7 cu. ft.” The third bullet says “Spacious 3.46 Cu. Ft. Oven Capacity”. The gap is 0.24 cu ft by our arithmetic, a little over 6% of the larger figure. At 3.7 the KoolMore ties the Haven at about 0.154 cu ft per inch; at 3.46 it drops to about 0.144, still second on the page and still well ahead of the Magnificent Chef 24-inch at 3.0. Either way it is a big oven for the width. But a buyer comparing it with the Haven should plan around the smaller figure until the manufacturer confirms which is right.

It states the biggest cooktop total on the page. “High-Performance 4-Burner Gas Cooktop (51,500 Total BTU): Features a powerful 18,000 BTU front burner for rapid boiling, along with three additional burners for simmering and everyday cooking versatility.” The 18,000 BTU front burner matches the Haven’s largest. The other three share the remaining 33,500 BTU, our subtraction, but the listing does not say how. So the KoolMore wins on total and on its top burner, and leaves you guessing whether any of the other three turns down as low as the Haven’s 3,500 BTU simmer burner.

It is the only slide-in range in this roundup. The title says “Slide-In Gas Range” and “Front Controls”. A slide-in is designed to sit between cabinets with the controls on the front rather than on a raised back panel, which gives a cleaner run of counter and keeps the knobs away from reaching over hot pans. Amazon still files it in Freestanding Ranges, at #54. The listing does not give exterior dimensions, so the cutout, the countertop overlap and the gas connection position have to come from the installation manual before you commit. That is a job for a qualified, licensed gas installer, not a weekend project.

Convection is stated; the gas setup is not. “Built-in convection fan circulates hot air throughout the oven cavity, helping ensure consistent cooking and baking results.” The KoolMore and the Haven are the only two ranges here that claim convection. What the KoolMore never says is whether it leaves the factory set for natural gas or propane, or whether a conversion kit exists. If you cook on propane, ask the seller in writing before ordering.

What to weigh. It is “CSA certified for safety and backed by a 1-year parts and labor warranty”, sold by Amazon.com and ranks #2,829 overall. The cooktop is “Black glossy enamel”. It lists 119.9 pounds. On the listing alone, it is the strongest stated cooktop here in the most built-in-looking format, with an oven that is either the biggest or the second-biggest on the page depending on which line you read.

Best for: A remodel that wants a slide-in look and the most stated burner power in 24 inches, with the gas setup confirmed first.

3. Magnificent Chef 24-Inch Freestanding Gas Range, 3.0 Cu Ft, MGR24DNM54TDIB — Best Warranty at 24 Inches

A middle-sized 3.0 cu ft oven in the shallowest stated body on the page, with natural gas stated and a 2-year warranty.

Key Specifications

Why We Recommend It

It sits exactly in the middle of the 24-inch field. The title says “3.0 Cu Ft Space Saver Oven”. That is 0.4 cu ft more than either Avanti and 0.7 less than the Haven, about 0.125 cu ft per inch by our arithmetic. For a buyer who finds the Avantis too small and the Haven too deep or too heavy, it is the step between them.

It is the shallowest range that gives a depth. “Dimensions: Height 41 3/16″, Width 24″, Depth 22 1/2″, Weight 108 Lbs.” At 22.5 inches deep it is more than five inches shallower than the 27.6-inch Haven, and about two inches shallower than its own 20-inch sibling, which lists 24 3/8 inches. In a galley kitchen or a narrow walkway, that depth can matter as much as the width. The spec table lists 109.0 pounds against the bullet’s 108; the difference is trivial, but it is a reminder to read both fields.

Natural gas is stated, and so is a route to propane, without a kit. “GAS TO LP ADAPTABLE: The freestanding range comes ready for natural gas use but can be adapted for propane use by switching the valves.” The listing does not say a conversion kit is included, and it does not describe what parts a conversion needs. Whatever the mechanism, a conversion changes how gas reaches the burners, so it should be done by a qualified, licensed gas installer following the manual and local code, not by the owner with a spanner.

The burners are described by speed, not by number. “Equipped with burners, 1 ultra-fast burner and 3 fast burners.” No BTU figure is given for any of them, and no simmer burner is named. The listing does say the burners are “Italian SABAF burners” and that the “cast iron grills are dishwasher safe”. Ignition type is not stated, which is unusual for a listing that names its burner supplier.

What to weigh. It carries a “2-Year Warranty”, double the one year on the Avantis, Haven and KoolMore, and it is “CSA-certified”. It is sold by Abba LLC rather than Amazon.com, the title says “Delivery Included”, and the first bullet warns that “Large appliance freight requires direct contact with the buyer before final placement.” It ranks #2,987 overall and #57 in Freestanding Ranges.

Best for: A shallow or galley kitchen that wants more oven than an Avanti on natural gas, with a longer warranty.

4. Magnificent Chef 20-Inch Freestanding Gas Range, 2.4 Cu Ft, MGR20DNM54TDIB — Largest 20-Inch Oven

The biggest oven a branded 20-inch listing states here, 2.4 cu ft, within 0.2 cu ft of the 24-inch Avantis.

Key Specifications

Why We Recommend It

For oven space in 20 inches, this is the branded listing to beat. The title says “2.4 Cu Ft Space Saver Oven”, about 0.120 cu ft per inch by our arithmetic. That is 0.35 cu ft more than the Lamazze, 0.3 more than the Avanti 20-inch and 0.1 more than the Summit. The unbranded 68-litre range converts to about the same figure. Set against the 24-inch Avantis at 2.6, it gives up only 0.2 cu ft for four inches less width.

The step up to its 24-inch sibling buys 0.6 cu ft. The Magnificent Chef 24-inch states 3.0 cu ft, so four extra inches add a quarter more oven, by our arithmetic. The same step in the Avanti line, from 2.1 to 2.6, adds 0.5. If you have the full 24 inches, the larger model is the better use of it; if you have 20, this one gives you the most of what 20 can hold among named brands.

It is narrower but deeper than the 24-inch version. “DIMENSIONS: Height 42 1/8″, Width 20″, Depth 24 3/8″, Weight 94 Lbs.” At 24 3/8 inches it is almost two inches deeper than the 24-inch Magnificent Chef, and at 42 1/8 inches it is the tallest range on the page that gives a height. Measure the depth of your counter run and any overhead cabinet clearance, not just the gap.

The gas wording is identical to the 24-inch model. “The freestanding range comes ready for natural gas use but can be adapted for propane use by switching the valves.” No kit is stated. The burners are described as “1 ultra-fast burner and 3 fast burners” from “Italian SABAF”, with no BTU figure for any of them and no named simmer burner. Ignition, broiler and convection are not stated.

What to weigh. It shares the 24-inch model’s “2-Year Warranty”, CSA certification and dishwasher-safe cast iron grates, and its seller and delivery terms: Abba LLC, delivery included, appointment required. It ranks #6,696 overall and #152 in Freestanding Ranges, well behind the Avanti 20-inch at #364, which holds 0.3 cu ft less.

Best for: A 20-inch slot on natural gas where oven space comes first and a 2-year warranty matters.

5. 20-Inch Gas Range with 4 Burners and 68L Rotary Baking Oven (SoirFanTlio) — Most Questions Open

A large stated oven for 20 inches and a conversion kit in the title, with almost nothing else a gas buyer needs to check.

Key Specifications

Why We Recommend It

On paper, the oven ties the biggest 20-inch figure here. The title says “68L Rotary Baking Oven” and the second bullet repeats “68-liter oven capacity”. 68 litres is about 2.40 cu ft by our conversion, level with the Magnificent Chef 20-inch and ahead of the Summit, Avanti and Lamazze. It is the only listing that gives capacity in litres, so it is easy to read past.

The kit is in the title, the direction is not. The title ends “(NG-LPG Conversion Kit)”. The listing never says which gas the range is set up for when it leaves the factory, so you cannot tell whether the kit converts natural gas to propane or the other way. The model fields read “Lpg-4b-68l” and “Lpg-20r68l”, which hint at propane, but a part number is not a statement. Whichever way it runs, the conversion should be carried out by a qualified, licensed gas installer following the manual and local code.

What rotates is not explained. “ROTARY BAKING: 68-liter oven capacity with 360-degree rotary baking function ensures even heat distribution for perfect cooking results.” The listing does not say whether that is a rotisserie spit, a turntable or something else, and it does not claim convection. Burner BTUs are not given (“Four high-efficiency gas burners with adjustable heat levels”), and neither are ignition type, broiler details or exterior dimensions beyond the 20-inch width.

It lists about half the weight of the other 20-inch ranges. 58.0 pounds against 94 to 142 pounds for the rest of the 20-inch group. The listing says the body is “201 stainless steel” with a “double-layer mirror tempered glass door”; the Lamazze, by contrast, describes a triple-layer door. Lighter construction is not a fault in itself, but it is a measurable difference in how much metal and insulation you are getting.

No safety listing is named. The Avantis state ETLus, the Magnificent Chefs and KoolMore state CSA; this listing names neither, and its “SAFETY FEATURES” bullet describes the glass and the knobs. For an appliance connected to a gas supply, a recognised certification mark is the first thing to confirm with the seller, and some local codes and installers will require it. The warranty field reads simply “2”. It is sold by Xinqiong Technology and ranks #2,200 overall, #29 in Freestanding Ranges, ahead of every non-Avanti range except the Haven.

Best for: Only a buyer who gets the gas setup, certification and warranty confirmed in writing before ordering.

6. Summit RG201B 20-Inch Wide Gas Range, 2.3 Cu Ft, ADA Compliant (Black) — Best 20-Inch

The best-documented cooktop among the 20-inch ranges: four BTU figures, electronic spark ignition and a separate broiler compartment.

Key Specifications

Why We Recommend It

It tells you more about its burners than any other 20-inch range except the Lamazze, and its numbers are bigger. “One 12,000 BTU burner offers faster cooking for larger pots and pans, with two standard 9,500 BTU burners, and a smaller 5,000 BTU burner for simmering.” That is 36,000 BTU across the cooktop by our arithmetic, the same total as the white Avanti’s four 9,000 BTU burners, but split into a genuine high burner and a genuine low one. The 12,000 BTU burner is about 41% more than the Lamazze’s 8,500 BTU rapid burner, by our arithmetic.

Ignition is named. “This Summit gas range utilizes electronic spark ignition.” It is one of only four listings on the page that name an ignition type; the other three are the Avantis. None of the ten describes battery spark. Electronic ignition means the range needs a power outlet for the spark, and the manual sets out the electrical connection along with the gas one.

The broiler is a separate compartment, and the pan is in the box. “Includes 2 slide-out racks and a lower drop-down broiler compartment … Includes a 2-piece broiler pan with lid.” Of the 20-inch ranges, only this one and the Lamazze describe a broiler at all, and only the Summit includes a pan. A drop-down compartment below the oven keeps broiling separate from baking, at the cost of a low, bending reach.

The oven is mid-pack for 20 inches. 2.3 cu ft is about 0.115 cu ft per inch by our arithmetic, or about 0.118 if you use the stated 19.5-inch width. It is 0.1 cu ft behind the Magnificent Chef 20-inch and 0.25 ahead of the Lamazze. The title says “(ADA Compliant)”, the only accessibility claim on the page, which can matter for rental units and accessible kitchens. At 142.0 pounds it is the heaviest 20-inch range here by a wide margin, and the bullet gives “42.0″ H x 19.5″ W x 23.5″ D”.

What is missing is the gas setup. The listing does not say whether it leaves the factory set for natural gas or propane, or whether a conversion kit is included. Neither is a warranty term given; the field reads “Summit Appliance Warranty”. It is sold by Buildcom, was scarce at capture, and ranks #7,233 overall and #167 in Freestanding Ranges. Confirm the gas type with the seller, and have a licensed installer handle any conversion.

Best for: A 20-inch kitchen that wants a real high burner, a real simmer burner and a proper broiler, and will confirm the gas setup first.

7. Avanti GRO24P0W 24-Inch Compact Freestanding Gas Range, 2.6 Cu Ft (White) — Best Value

The only 24-inch listing that puts a propane conversion kit in the box, with four equal 9,000 BTU burners and a broiler drawer.

Key Specifications

Why We Recommend It

This is the 24-inch range to buy if your gas comes from a propane tank. The fourth bullet reads “A broiler drawer, two oven racks, storage drawer, and included propane conversion kit add everyday versatility.” Among the five 24-inch listings, it is the only one that says the kit is in the box. The Haven sells it separately, the Magnificent Chef describes switching valves without a kit, and the stainless Avanti and the KoolMore say nothing. A kit included does not make conversion a DIY job: the orifices and regulator should be changed by a qualified, licensed gas installer following the manual and local code. It does mean the installer is not waiting on a part.

The burners are four of a kind. “Four 9000 BTU burners help you boil, simmer, and prepare multiple dishes at once.” That is 36,000 BTU across the cooktop, by our arithmetic, the same total as the Summit 20-inch. The difference is the spread. The Summit gives you 12,000 at the top and 5,000 at the bottom; the Avanti gives you 9,000 everywhere. Four equal burners are flexible for pan placement, but there is no dedicated high-output burner and no stated simmer burner, so very low simmering depends on how far each valve turns down.

The oven is the smallest in the 24-inch class. 2.6 cu ft, about 0.108 cu ft per inch by our arithmetic, or about 0.111 using the stated 23.5-inch width. That is 0.4 cu ft behind the Magnificent Chef 24-inch and 1.1 behind the Haven. It is still 0.5 cu ft more than the Avanti 20-inch, and the listing is honest about what it is: “A 2.6 cu. ft. oven gives smaller kitchens room for everyday baking and roasting.”

The broiler is a drawer. The title says “Includes Broiler Storage Drawer and Accessories”, and the bullet separates a “broiler drawer” from a “storage drawer”. Ignition is named in the title as “Electronic Ignition”. It is “ETLus listing, DOE certification”, with a one-year limited warranty.

What to weigh. It is sold by Amazon.com, ranks #1,350 overall and #12 in Freestanding Ranges, and lists 95.0 pounds, the lightest of the 24-inch ranges. It is the lowest-priced 24-inch range here at capture. The listing does not state its factory gas type in words, though a propane conversion kit implies it is not set up for propane out of the box; confirm with the manual before the installer arrives.

Best for: A propane kitchen with a 24-inch slot that wants the kit in the box and a straightforward four-burner cooktop.

8. Avanti GR2416CSS 24-Inch Compact Gas Range, 2.6 Cu Ft (Stainless Steel) — Best-Ranked 24-Inch

The best-selling 24-inch range on the page, and the one that tells you least about its burners and its gas.

Key Specifications

Why We Recommend It

More shoppers choose this than any other 24-inch range here. It ranks #860 overall and #5 in Freestanding Ranges, second on the page only to its 20-inch sibling. It is sold by Amazon.com, and was flagged as scarce stock at capture. Whatever drives that, it is not oven space per inch: at 2.6 cu ft it shares the bottom of the 24-inch class with the white Avanti, about 0.108 cu ft per inch by our arithmetic.

The burners are named by role, not by number. “Four sealed burners, including rapid, semi-rapid, and simmer options, help you handle different cooking tasks with easier cleanup.” That is a better description of the layout than the white Avanti gives, because it promises a dedicated simmer burner, but no BTU figure is printed for any of the four. You cannot compare it with the Haven’s 18,000 BTU or the Summit’s 12,000 BTU from the listing.

The gas setup is not mentioned at all. No factory gas type, no conversion kit, no conversion route. Its white sibling includes a propane kit; this listing is silent. If you cook on propane, that silence is the single most important thing to resolve before ordering, by asking the seller or reading the manual. Any conversion, if one is possible, should be done by a qualified, licensed gas installer following the manual and local code.

The everyday features are spelled out. “Automatic electronic ignition, full-range temperature control, and a 60-minute timer”, plus “Two oven racks, a glass oven door, an oven light, and a lower storage drawer”. The first bullet says the oven gives “room to bake and broil”, but it does not say where the broiler is, whether a drawer or inside the oven. Convection is not stated. It is “DOE Certified and ETLus Listed”, and the energy field reads “High Efficiency”.

What to weigh. The listed height is 40.75 inches and the width 23.5; the length field gives 25.0 inches. It lists 114.0 pounds, 19 pounds more than the white Avanti with the same stated oven. The warranty is one year limited. If you want the Avanti 24-inch on propane, the white GRO24P0W documents the kit and the burner BTUs; this one documents the simmer burner and the rank.

Best for: A natural gas kitchen, confirmed from the manual, that wants the best-selling 24-inch range and a named simmer burner.

9. Avanti GR2013CSS 20-Inch Compact Gas Range, 2.1 Cu Ft (Stainless Steel) — Best Seller Here

The best Best Sellers Rank on the page, a 2.1 cu ft oven, and a BTU figure that could mean three different things.

Key Specifications

Why We Recommend It

This is the range shoppers pick most often on this page. It ranks #364 overall and #3 in Freestanding Ranges, ahead of every 24-inch model here. It is sold by Amazon.com and was scarce at capture. For a buyer searching for the best 20 inch gas stove, it is the obvious first look, and on oven space it is one of the smaller choices.

2.1 cu ft is second-smallest in the 20-inch group. The bullet says “The 20 inch freestanding footprint and 2.1 cu. ft. oven”, about 0.105 cu ft per inch by our arithmetic. Only the Lamazze, at 2.05, is smaller. The Magnificent Chef 20-inch and the unbranded 68-litre range both hold about 0.3 cu ft more in the same width, and the Summit 0.2 more. Stepping to the Avanti 24-inch adds 0.5 cu ft.

The BTU claim needs a question. “Four gas burners and 8800 BTU output help you prepare multiple dishes.” The listing does not say whether 8,800 BTU is each burner, the largest burner or the whole cooktop. If it is the total, it would be well under half the Lamazze’s stated 21,200 BTU; if it is per burner, it would be close to the white Avanti’s 9,000. Those are very different cooktops. Ask the seller, or read the manual, before comparing it with anything.

The gas setup is not stated. No factory gas type, no kit. Like its stainless 24-inch sibling, the listing leaves it out entirely. Ignition is named: “Dial controls, automatic electronic ignition, an oven light, and a 60 minute timer.” Broiler and convection are not stated.

What to weigh. It is “DOE certification, ETLus listing, and a 1 year limited warranty”, and its energy field reads “Energy Star Certified”, a claim we cannot check from the listing. It lists 104.0 pounds, 40.25 inches tall and 19.75 inches wide. Its rank says it is the default choice; its listing says to confirm the burner output and the gas type before you make it yours.

Best for: A 20-inch natural gas kitchen, confirmed from the manual, that wants the most widely chosen compact range here.

10. Lamazze 20-Inch Gas Range, 4 Sealed Burners, 21,200 BTU, 2.05 Cu Ft (White) — Clearest Gas Setup

The most complete gas paperwork on the page, natural gas stated with an LP kit included, on the smallest oven and the gentlest cooktop.

Key Specifications

Why We Recommend It

No other listing answers the gas question as completely. “Comes ready for natural gas and includes a liquid propane (LP) conversion kit and adjustable legs.” It is the only range on the page that states both the factory gas type and an included kit. Every other listing leaves out one half or both. For a buyer who does not yet know whether the next kitchen will be on a main or a tank, that is a real advantage. It does not change who fits the kit: conversion is work for a qualified, licensed gas installer following the manual and local code.

Every flame is itemised. “An 8,500 BTU rapid burner for quick boiling, two 5,000 BTU semi-rapid burners for everyday tasks, and a 2,700 BTU simmer burner for delicate sauces.” Those add to the 21,200 BTU in the title, which we checked. The oven is “split into a 6,500 BTU bake element and a 6,500 BTU broil element”. The 2,700 BTU simmer burner is the lowest figure printed anywhere on the page, which is good news for sauces and melting chocolate.

It is also the gentlest cooktop here. 21,200 BTU in total is about 41% of the KoolMore’s 51,500, by our arithmetic, and its 8,500 BTU rapid burner is less than half the Haven’s 18,000. Against the Summit, another 20-inch range, the Lamazze gives up 3,500 BTU on the biggest burner and 14,800 BTU across the cooktop. It will boil water, but more slowly than the stronger ranges here.

The oven is the smallest on the page. “2.05 CU. FT. OVEN WITH 13,000 BTU OUTPUT”, about 0.103 cu ft per inch by our arithmetic. Per cubic foot, its 6,500 BTU bake burner works out at about 3,170 BTU, close to the Haven’s 12,000 BTU on 3.7 cu ft at about 3,240, our arithmetic. So the oven is small, not underpowered for its size. It has “an internal cooling fan” for thermal management, which is not the same as convection, and the listing does not claim convection.

What to weigh. The build details are generous: “thick, triple-layer tempered glass”, a “G9 halogen light”, “5 heavy-duty zinc-coated metal knobs”, continuous cast iron grates and a storage drawer. The warranty is “2 year on parts and labor”. The brand and manufacturer fields both read Forno. It lists 118.6 pounds, is sold by Home Best Price Products Inc., and ranks #14,783 overall, the lowest rank on the page. Ignition and exterior dimensions are not stated.

Best for: A 20-inch kitchen that may move between natural gas and propane and values gentle simmering over fast boiling.
