What Size Gas Cooktop Do You Need? A Countertop, Burner and Chimney Matching Guide

The gas stove size question sounds simple until you stand in a showroom with a tape measure and a dozen glass-topped or steel-topped cooktops staring back at you. Too small and the big kadhai hangs off the edge of the burner. Too large and it crowds the counter you need for chopping. We make these cooktops, and chimneys to sit above them, so we have watched this exact puzzle play out more times than we can count.

This guide turns that puzzle into a few clear decisions. We will explain how cooktop width relates to burner count, how to measure your counter for one, why the chimney above it has to be matched too, and the breathing room a cooktop needs to stay safe. By the end, the right gas stove size for your kitchen should be a number you can almost read off your own countertop.

Two Numbers Decide Everything: Counter Width and Burner Count

Before any model name enters the picture, two numbers set the whole decision. The first is how much counter width you can give the cooktop. The second is how many burners your cooking actually needs. Get these two straight and the rest is detail.

Counter width is the hard limit, the stretch of worktop where the cooktop will live, minus the clearance it needs on each side. Burner count is the softer choice, driven by how many pots you run at once on a busy evening. A household that cooks one dish at a time has very different needs from a joint family with four pans going before dinner. Neither household is wrong, they simply land on different gas stove size answers, which is exactly why a single recommendation for everyone would be useless.

We will be honest about a trap here. Many buyers pick the burner count first and then try to force that cooktop onto a counter that cannot really take it. The wiser order is to measure the counter first, see what width it allows, and then choose the most useful burner layout that fits inside that width.

Cooktop Width by Burner Count

Here is where the gas stove size becomes concrete, because width and burners move together. A four-burner cooktop packs four flames into a body, so it needs a certain minimum width. A three-burner cooktop often spreads three larger burners across a wider body, which sounds backwards until you see why.

The counter-intuitive truth is that a three-burner gas stove size is frequently as wide as, or wider than, a four-burner one. The reason is spacing. Three big burners spaced generously apart give room for three large vessels at once, while four burners squeezed close together suit smaller, everyday pans. Our own range shows this pattern clearly.

Read down that table and the logic lands. A compact four-burner like the CTS 58 4B AI fits a tight counter, the CTC 69 4B gives four burners more elbow room, and the wider three-burner CTH75 and CTJ 77 trade a fourth flame for three roomy ones that swallow big pots. So a four-burner gas stove size is not automatically the largest, and the right pick depends on whether you want more burners or more space per burner.

How to Measure Your Counter for a Cooktop

Measuring sounds obvious, yet it is where most mismatches begin, so it is worth doing properly. You are measuring three things, the available width, the depth of the counter, and the clearances the cooktop needs around it. A tape measure and five quiet minutes settle all three.

• Width is the run of free counter where the cooktop will sit, the figure you compare against the cooktop's own width.
• Depth is the distance from the front edge of the counter to the wall behind, which must comfortably hold the cooktop's depth with room front and back.
• Clearance is the empty space you must leave on each side and behind, so the cooktop is not jammed against a wall or a tall unit.

A common counter is around 60 cm deep, which suits most cooktops with room to spare. The width is the figure that varies most from kitchen to kitchen, and it is the one to guard. We suggest noting the raw width first, then subtracting your side clearances, and only then shopping for a cooktop that fits the number left over.

Do not forget the gas point while you are measuring. A free-standing cooktop connects to your gas supply by a pipe at the back or side, so leave a little room behind it for that connection and the regulator rather than pushing the cooktop flush to the wall. A cooktop crammed tight against the tiles often leaves no honest path for the gas hose, which the fitter discovers on the day.

For a built-in hob, which drops into a cut-out in the counter rather than resting on top, there is one extra number. The cut-out size is the hole the installer makes, and it is smaller than the overall cooktop. Always cut to the supplied template, since a hole sawn too wide cannot be made narrow again.

Burner Spacing and the Size of Your Vessels

Width is not only about fitting the counter, it is about fitting your pots, and this is the part spec sheets rarely explain. Gas stove burner spacing is the gap between one burner and the next, and it decides whether two large vessels can sit side by side without knocking. A wider cooktop gives more spacing, and more spacing means bigger pans at the same time.

Think about your heaviest cooking moment, the one with the pressure cooker, the kadhai and the tawa all going. On a narrow cooktop those vessels jostle, their handles clash, and you end up cooking in shifts. On a wider one with generous spacing they coexist, which is the whole point of paying for the extra width.

This is why vessel size belongs in the decision, not just burner count. If your kitchen runs to large kadhais and tall cookers, a wider cooktop with a jumbo burner, like the CTH75 or CTJ 77, earns its width every meal. If you mostly use small and medium pans, a compact four-burner gives you four flames without the sprawl. The pots you actually own are a better guide than the burner number alone. We have seen a buyer choose a four-burner for the higher number, then realise their two favourite kadhais would never fit on it together.

Clearance: The Breathing Room a Cooktop Needs

A cooktop is a flame on a counter, so the space around it is a safety matter, not just a styling one. Leaving clearance on both sides and behind keeps heat away from walls, tall units and anything that should not meet a flame. We treat this as part of the gas stove size, because a cooktop that fits the counter but not the clearances does not really fit at all.

Keep flammable things well clear of the burners, the curtains, the plastic bottles, the wooden spice rack that always creeps too close. Side clearance also gives your hands room to work, to lift a hot vessel without grazing a wall. A cooktop wedged into a corner is awkward to cook on and harder to clean around, which you feel every single day. Corner clearance matters for cleaning too, since spills and oil splatter love the gap between a burner and a wall.

There is a vertical clearance too, between the cooktop and whatever hangs above it, which is usually the chimney. That gap matters for both safety and performance, and it leads us neatly to the appliance that has to be matched to the cooktop just as carefully as the counter does.

Matching the Chimney to the Cooktop

Here is the rule we wish every buyer knew before they shopped, because it prevents the most common regret. A chimney should be at least as wide as the cooktop beneath it, and never narrower. The chimney's job is to catch rising smoke and fumes, and a chimney narrower than the cooktop simply lets the edge burners send their smoke into the room.

Picture the chimney as an umbrella over the flames. An umbrella narrower than you are leaves your shoulders in the rain, and a chimney narrower than the cooktop leaves the outer burners unguarded. So the chimney width should equal or exceed the cooktop width, never less. This single rule resolves most of the confusion buyers bring us.

Our chimneys come in 60 cm, 75 cm and 90 cm widths to make this matching straightforward. A 60 cm cooktop pairs with a 60 cm chimney as a minimum, though many buyers size up for better capture. A wider cooktop steps up to a 75 cm or 90 cm chimney so the canopy covers every burner. The pairing is meant to be simple once you know which way the rule runs.

Chimney Size for Three-Burner and Four-Burner Stoves

Putting numbers to that rule helps, since burner count is a handy shorthand for width. A compact four-burner cooktop around 58 to 60 cm sits happily under a 60 cm chimney, and steps up to 75 cm or 90 cm if you want stronger smoke capture or plan a wider cooktop later. The chimney size for a four-burner stove is really set by the cooktop's width, not the burner number alone.

For a wider three or four-burner cooktop in the 69 to 77 cm range, a 90 cm chimney is the comfortable match, with 75 cm as the close fit. The chimney size for a three-burner stove tends to run wider precisely because those three-burner cooktops are wider, which loops back to the spacing point from earlier. A 90 cm chimney over a 75 cm cooktop is generous and effective, never a mistake.

The question we hear most is whether a wider cooktop can sit under a narrower chimney, and the answer is a firm no. A 75 cm cooktop under a 60 cm chimney leaves its outer burners beyond the canopy, so smoke escapes at the very edges where you least want it. Always let the chimney be the wider of the two, or at least equal, and the air above your cooking stays clear.

Free-Standing Cooktop or Built-In Hob

A quick word on a choice that affects how you measure. A free-standing cooktop rests on top of the counter and connects to the gas point, which makes it simple to place and to replace. Most of our glass cooktops, like the CTS, CTC, CTH and CTJ models, work this way, sitting on the worktop with their own footprint.

A built-in hob drops into a cut-out so its surface sits almost flush with the counter, for a sleek, integrated look. The trade is that a built-in hob needs that hole cut precisely and a cabinet below sized to take it, so it asks for more planning. For measuring, a free-standing cooktop cares about the surface footprint, while a built-in hob cares about the cut-out as well.

Neither is better in the abstract, and the gas stove size logic applies to both. Measure the counter, match the width to your burner needs, leave the clearances, and size the chimney to the cooktop. The only extra step for a built-in hob is cutting to the template, which a careful installer handles without drama.

Suction and Installation Height Belong With Size

Width is the headline of chimney matching, but two partners travel with it, the suction strength and the mounting height. Sizing the cooktop and chimney width correctly does little good if the chimney is too weak for the kitchen or hung at the wrong height. So we fold both into the sizing conversation rather than leaving them as afterthoughts.

Suction is the chimney's pulling power, the volume of air it clears each hour, and it should rise with the size of the kitchen and the heat of the cooking. A small kitchen with a compact cooktop needs less pull than a large open kitchen where a wide cooktop runs hard every evening. A roughly sensible pairing looks like this.

• A small kitchen with a 2 to 4 burner cooktop pairs well with a 60 cm chimney of moderate suction.
• A medium kitchen with a 3 to 4 burner cooktop suits a 75 cm or 90 cm chimney with stronger suction.
• A large or open kitchen with heavy daily cooking wants a 90 cm chimney and the highest suction on offer.

Mounting height is the other partner, the gap between the cooktop and the chimney above it. Set too high and the chimney struggles to catch the smoke before it spreads, set too low and it sits in the heat of the flames. A comfortable working gap, neither cramped nor stretched, lets the chimney do its job while keeping clear of the burners, and your installer can advise the exact figure for the model you choose.

A Quick Sizing Checklist

To pull the whole guide into one place, here is the short checklist we would hand a friend before they buy. Run it in order, because each step depends on the one before it.

1. Measure the free counter width and the counter depth where the cooktop will sit.
2. Subtract the side and rear clearance the cooktop needs, and note the width left over.
3. Decide your burner count and think about the size of the vessels you cook in most.
4. Pick a cooktop width that fits the leftover space, more burners for many small pans, more spacing for big ones.
5. Size the chimney to equal or exceed the cooktop width, choosing 60 cm, 75 cm or 90 cm to match.
6. Check the suction against your kitchen size and confirm a sensible mounting height with the installer.

Tick those six and the appliances will fit each other and the room. The gas stove size, the counter and the chimney stop being three separate worries and become one tidy decision.

Putting It All Together

We will leave you with the principle we trust most, learned from kitchens rather than catalogues. The best gas stove size is the one that matches your counter, your pots and your chimney all at once, not the widest one on the shelf or the one with the most burners. A cooktop that fits its space, breathes safely, and sits under a chimney that covers it completely is the one you stop thinking about, which is exactly what a good appliance should let you do.

Frequently Asked Questions

Q. What is the standard width of a three-burner gas stove?

A. Three-burner cooktops are often wider than buyers expect, commonly in the 70 to 78 cm range, because the three larger burners are spaced apart for big vessels. Our CTH75 is 75 cm and the CTJ 77 is 77 cm, for example. The width comes from generous burner spacing rather than from the number of burners.

Q. What cooktop size suits a 60 cm kitchen counter?

A. A 60 cm counter run comfortably takes a compact cooktop around 58 to 60 cm, such as our CTS 58 4B AI, once you allow side clearance. Measure the free width first, subtract the clearance you need on each side, and choose a cooktop that fits the figure left over rather than filling the counter edge to edge.

Q. How much space should be left around a cooktop?

A. Leave clearance on both sides and behind so the flames are away from walls, tall units and anything flammable like curtains or plastic. Side space also gives your hands room to lift hot vessels safely. A cooktop jammed into a corner is unsafe and awkward to clean, so treat clearance as part of the size you need.

Q. Should the chimney be wider than the gas stove?

A. The chimney should be at least as wide as the cooktop, and wider is fine. Its job is to catch rising smoke, and a chimney narrower than the cooktop leaves the outer burners uncovered, letting their smoke escape into the room. Equal width is the minimum, and sizing up improves capture.

Q. What chimney size is suitable for a four-burner cooktop?

A. It depends on the cooktop's width, not the burner count alone. A compact four-burner around 58 to 60 cm pairs with a 60 cm chimney as a minimum, while a wider four-burner near 69 cm suits a 75 cm or 90 cm chimney. Match the chimney to the actual cooktop width and you will not go wrong.

Q. Can a 75 cm cooktop fit under a 60 cm chimney?

A. No, and it is worth being firm about this. A 75 cm cooktop under a 60 cm chimney leaves its outer burners beyond the chimney's canopy, so smoke and fumes escape at the edges. The chimney must be at least as wide as the cooktop, so a 75 cm cooktop wants a 75 cm or, better, a 90 cm chimney.

Q. How should cooktop dimensions be measured?

A. Measure the cooktop's overall width and depth, the footprint it occupies on the counter. Then measure your counter's free width and depth, and the clearances you must leave around it. For a built-in hob, also note the cut-out size, the hole made in the counter, which is smaller than the overall cooktop.

Q. Does burner spacing change with cooktop width?

A. Yes, and it is a key reason to consider width. A wider cooktop spreads its burners further apart, so two large vessels can sit side by side without their handles clashing. A narrow cooktop packs the burners close, which suits smaller pans but makes cooking with several big pots at once a tight squeeze.

Q. What cooktop size is suitable for a compact modular kitchen?

A. A compact modular kitchen usually suits a cooktop around 58 to 60 cm, like our CTS 58 4B AI, which gives four burners without eating the counter. The trick is to protect your prep space, since a cooktop that is too wide leaves nowhere to chop. Measure the counter and keep some clear worktop beside the cooktop.

Q. Should vessel size be considered while selecting cooktop width?

A. Absolutely, since the pots you own decide whether the burners are useful. If you cook in large kadhais and tall cookers, a wider cooktop with a jumbo burner and generous spacing, such as the CTH75 or CTJ 77, earns its width. If your pans are mostly small and medium, a compact four-burner serves you well.

Q. Is a three-burner or four-burner cooktop better for an Indian kitchen?

A. Both work, and the choice is about pots versus flames. A four-burner suits running several smaller pans at once, while a wider three-burner gives more room per burner for big vessels. For families who cook large quantities in big kadhais, the spacing of a three-burner often beats the extra flame of a cramped four-burner.

Q. Does auto ignition change the size of a cooktop?

A. No, auto ignition does not change a cooktop's footprint. It is a starting mechanism that lights the burner at the turn of a knob, with no separate lighter needed, and several of our models offer it. Choose the size by counter and burner needs, then pick the auto-ignition variant if you prefer the convenience.

Q. What is the difference between a cooktop and a built-in hob in terms of size?

A. A free-standing cooktop rests on the counter, so you measure its surface footprint against your free counter width. A built-in hob drops into a cut-out and sits nearly flush, so you also measure the cut-out and the cabinet below. The cooking widths are similar, but the hob needs the extra cut-out planning.

Q. How deep does a counter need to be for a gas cooktop?

A. A counter depth of around 60 cm comfortably holds most cooktops with room at the front and back. The cooktop's own depth should sit within that with clearance behind, so it is not pressed against the wall. Always check the cooktop's depth against your counter, not just the width, before buying.

Q. Does a bigger cooktop always cook better?

A. Not necessarily, since the right size is about matching your needs, not maximising width. A cooktop too large for the counter steals prep space and crowds the kitchen, while one too small cramps your vessels. The cooktop that fits your counter, suits your pots, and sits under a matching chimney is the one that cooks best for you.
