How to Measure Up for Banquette Benches: A Simple Sizing Guide

To measure for a banquette bench, record five key figures: the length of the wall or alcove, the height of your dining table, the clearance under the tabletop, the depth you can spare from the room, and the position of any obstacles such as radiators, sockets and window sills. As a working guide, aim for a finished seat height of 45 to 48cm, a usable seat depth of 45 to 50cm, and around 55 to 60cm of seat length per adult. Leave roughly 25 to 30cm between the seat front and the table edge so people can slide in comfortably.

Careful measuring is what separates a banquette that feels natural from one that feels cramped. Whether you are planning fitted joinery or using a freestanding piece from our range of modern dining benches UK, the steps below will help you get the proportions right first time.

What You Need Before You Start

Gather a few simple tools:

• A metal tape measure, ideally at least five metres long.
• A notebook or squared paper for a quick sketch.
• Masking tape for marking outlines on the floor.
• A spirit level, helpful if your floor or walls are uneven.
• Your dining table, or its exact dimensions if you have not bought it yet.

Older UK homes rarely have truly straight walls or level floors, so measure in more than one place and use the smallest figure.

Step One: Measure the Wall or Alcove

Start with the length of the wall where the banquette will sit. Measure at floor level, at seat height and at the height of the backrest. Walls can bow, and skirting boards or plaster ridges can make a difference of a centimetre or two.

If the banquette sits in an alcove or corner, measure each wall separately and note the angle. Corners in older properties are often not quite square. A large set square or a simple check using the 3, 4, 5 method can tell you how far off it is.

For bay windows, measure each section of the bay separately and record the angles between them. Bay banquettes nearly always need bespoke joinery, so a clear sketch with all measurements is invaluable when you speak to a maker.

Step Two: Note Every Obstacle

Next, mark anything that might interfere with the banquette:

• Radiators: Note their height, depth and the position of valves. Placing a banquette in front of a radiator reduces heat output and can dry out timber.
• Sockets and switches: Record their height from the floor and distance from the corner. A banquette back can block them.
• Window sills: Measure their height and depth. A backrest needs to finish below the sill, and cushions should not block window handles.
• Skirting boards: Note their depth, as they push freestanding pieces away from the wall.
• Doors: Check that nearby doors can open fully once the banquette and table are in place.

Step Three: Measure the Table

The table defines most of the banquette’s dimensions. Measure:

• Table height: Usually around 75cm in UK homes.
• Underside clearance: The distance from the floor to the bottom of the tabletop or apron. This decides how much thigh room people will have.
• Tabletop length and width.
• Base type and position: Corner legs, a pedestal or a trestle. Corner legs can obstruct people sliding in, so note how far they sit from the table edge.

If you are still choosing a table, our dining table and chairs sets UK sale collection lists full dimensions, which makes it easy to plan the banquette and table together.

Step Four: Work Out Seat Height

The finished seat height, measured to the top of the seat cushion when someone is sitting on it, should leave around 27 to 30cm between the seat and the tabletop. With a standard table, that gives a compressed seat height of about 45 to 48cm.

Remember that cushions compress. If you are planning a fitted base with a loose cushion on top, measure the base height and add the compressed cushion thickness, not the uncompressed thickness. A 10cm foam cushion might compress to 7 or 8cm when sat on.

Step Five: Decide on Seat Depth

Seat depth is measured from the front edge of the seat to the backrest. For comfortable dining, a usable depth of 45 to 50cm works for most adults. If you are using a wall with loose cushions as the back, measure from the seat front to where the compressed cushion will sit, not to the wall itself.

Too shallow and people perch on the edge. Too deep and they sit too far from the table, which is uncomfortable for eating. If the room is tight, 40cm is a reasonable minimum, though longer meals may feel less relaxed.

Step Six: Calculate Seat Length

Allow about 55 to 60cm of seat length per adult. A banquette of 120cm will comfortably seat two adults, and a 180cm banquette will seat three. Children need less space, so a family of four might fit along a 150cm seat for everyday meals.

For L shaped corner banquettes, remember that the corner itself is less comfortable. People sitting there have their knees pointing at a table leg or corner. Many designers treat the corner as shared space rather than a full seat.

Step Seven: Plan the Gap to the Table

The relationship between the banquette and the table matters as much as the banquette itself. The front of the seat should sit under the table edge by a few centimetres, leaving a clear gap of around 25 to 30cm between the seat front and the table edge above. This gives enough room to slide in without having to move the table each time.

A pedestal or trestle base makes this far easier, as there are no corner legs to manoeuvre around. Our range of modern dining tables UK includes pedestal and trestle designs well suited to banquette seating. If you need flexibility for guests, an option from our extending dining tables UK sale collection lets you add length when the banquette is fully occupied.

Step Eight: Check Circulation Space

On the open side of the table, leave enough room for chairs to be pulled out and for people to walk behind them. As a general guide, allow at least 90cm from the table edge to the nearest wall or obstacle, and more if this is also a walkway.

At either end of the banquette, leave space for people to get in and out. In a corner arrangement, at least one end should be open.

Step Nine: Mark It Out

Before committing, use masking tape to mark the banquette footprint and the table position on the floor. If possible, place your table in position and sit on chairs at roughly seat height where the banquette will go. Spend a few minutes sitting, standing and moving around. This simple step catches most problems before any money is spent.

Common Measuring Mistakes

• Forgetting cushion compression, which leaves the seat too low.
• Ignoring skirting boards, which push freestanding banquettes forward.
• Measuring only once on an uneven wall or floor.
• Blocking radiators or sockets with the backrest.
• Choosing a table with awkward legs that make sliding in difficult.
• Making the seat too deep, so diners feel far from the table.

Recording Your Measurements Clearly

Write every figure on a simple sketch of the room, with the banquette wall drawn as a straight line and each obstacle marked in position. Note whether each figure was taken at floor level, seat height or backrest height. If you are working with a joiner, a clear sketch with consistent units, ideally all in millimetres, avoids confusion and expensive mistakes.

Take photographs of the space from several angles as well. They help a maker understand details such as skirting profiles, socket positions and the shape of the window reveal.

Planning With Confidence

A well measured banquette feels effortless to use. Record the wall, obstacles and table carefully, aim for standard seat height and depth, allow enough length per person and leave a comfortable gap to the table. Mark it out on the floor before committing, and you will avoid the most common problems. Explore our dining range at Furniture in Fashion, with free delivery to most UK mainland postcodes.

Frequently Asked Questions

What is the standard seat height for a banquette?

Around 45 to 48cm from the floor to the top of the compressed seat cushion. This leaves roughly 27 to 30cm between the seat and a standard 75cm table.

How deep should a banquette seat be?

A usable depth of 45 to 50cm suits most adults. In tight spaces, 40cm is a reasonable minimum, although it may feel less comfortable for long meals.

How much space does each person need on a banquette?

Allow about 55 to 60cm of seat length per adult. Children need slightly less.

Can I put a banquette in front of a radiator?

It is best avoided, as it reduces heat output and can dry out timber and upholstery. If unavoidable, leave a ventilation gap and use a grille in the front panel.

What table base works best with a banquette?

Pedestal and trestle bases work best because they leave the table edges clear, making it easier to slide in and out.
