Hob Measurement Guide
Got your eye on that fancy new hob? You’ll need to know if it’ll fit in your kitchen first. We’ve put together some handy tips that’ll help you make sure you get that perfect fit.
How to measure
There's lots of things to think about when measuring a hob to get that perfect fit. So we've helped break it down. Make sure you check the hob type to ensure you've covered all bases.

Top tips
The cut out
The top of your hob is designed to be wider than the part that fits into your worktop, so when you make the cut-out, it should be slightly smaller than the hob itself - this way, the hob sits securely on top and covers the edges of the hole for a neat, safe finish.
Switching things up?
If you’re swapping from a gas hob to an induction one (or the other way round), just check the height of your new hob. Different types can be different sizes, so it’s worth making sure your new one will fit nicely in your kitchen.
Width and depth
The standard measurements for most models you’ll see are a width of 60 – 90cm and depth of 52cm.
Space for other appliances
Got an oven that’s built into your kitchen counter? You’ll need to allow for a 2.5cm gap between the top of the oven and underside of the hob for air to circulate.
No cupboards
For safety reasons, make sure there are no cupboards hanging over where you want to fit the hob.
Clearing the air
To properly clear steam, smoke, and cooking smells, you’ll need the width of your hob to be the same or less than your extractor fan.
Gas hobs
What you need to know
Gas hobs have a hot zone of 75cm. This is the space between the hob surface and extactor fan that heats up while you’re cooking, so it’s important to make sure there are no flammable things, like wallpaper or plug sockets in this area.
You’ll need to leave lots of room underneath for pipes, wiring, and airflow.
Induction hobs
What you need to know
For induction hobs, the hot zone is 65cm.
When fitting your hob, you’ll want to make sure you leave 9cm either side so that the hob fits safely with proper ventilation.
You’ll also want to make sure the power supply is close by for easier installation.
Ceramic hobs
What you need to know
If you’ve got a ceramic hob, the hot zone is 65cm.
Because these models typically don’t have internal cooling fans, they need less space for ventilation underneath.
Again, for these models, you’ll want to make sure the electrical connections are close by for a simpler installation.
Dual Fuel hobs
What you need to know
If you’re going for a dual fuel hob, the hot zone will be 75cm. As these models use two fuel types, you’ll need to leave enough room underneath for the pipes.
You’ll also want to check that the power and gas supplies are close enough for a straightforward installation.
Extractor hobs
What you need to know
Make sure there’s enough room under your worktop to fit both the hob and the extractor comfortably.
Have a quick check of the ducting size – you’ll usually need to know both the diameter and the length.
If the ducting comes out the back of the hob and runs downward, you’ll need to allow a bit of extra space between the ducting and the edge of your worktop.
Our product pages have all the info you need when it comes to measurements and dimensions. Always double-check these to make sure the hob you’re after is the perfect fit for your kitchen.

FAQs
- What is a hob measurement guide?
Our hob measurement guide helps you make sure your shiny new hob fits perfectly into your kitchen worktop with no last-minute DIY dramas. It shows you the cut-out dimensions (the space your hob needs to sit in), plus the overall size of the appliance itself. You’ll also find info on clearance space around the edges and underneath, so everything stays safe and snug.
- How do I measure a hob correctly?
Measuring a hob is easier than you think. Just grab a tape measure and check the width, depth, and height of the space where it’ll sit. Most hobs are around 60cm wide, but you’ll also find 70cm and 90cm models if you’ve got more room or love cooking big meals. Make sure there’s enough clearance around the edges (especially if it’s near a wall or cupboard), and don’t forget to check the cut-out size in your worktop if you’re replacing an old one – that’s the bit the hob actually drops into. If you’re going for a built-in model, double-check the installation requirements too, just to keep things safe and snug.
- What are the standard dimensions for a hob?
Hobs come in a few standard sizes, so it’s good to know what’ll fit your kitchen. Most models are around 60cm wide, which is perfect for standard worktops and usually gives you four cooking zones. If you’ve got more space (or a bigger appetite), you can go for 70cm or 90cm models – ideal for five or six zones and a bit more elbow room. Depth and height are usually standard, so the width is the main thing to check. And if you’re going for a built-in look, make sure your worktop cut-out matches the hob’s dimensions.
- Why is accurate hob measurement important?
Accurate hob measurement is key to making sure it fits your worktop perfectly – too big and it won’t slot in, too small and you’ll be left with awkward gaps. It’s especially important for built-in models, where the cut-out size needs to match exactly. Getting it right means a sleek finish, safe installation, and no surprise fitting costs. So, grab a tape measure and double-check before you buy.
- What tools are needed for hob measurement?
Measuring for a hob is easy with the right tools. You’ll need a tape measure for width, depth and cut-out size, a spirit level to check your worktop’s flatness, and maybe a pencil and ruler to mark things out. If you’re replacing an old hob, grab the installation manual too – it’ll show you the exact dimensions you need.
