Banquette Seating Dimensions
The sizes that make a banquette a place people stay after breakfast.
The short answer
If you are planning a banquette for your kitchen, aim for a seat 18 inches high and a table 30 inches high. That puts the tabletop 12 inches above the cushion, and the taller table leaves your legs the most room under it.
Measure that 18 with the cushion on and someone sitting on it. A bench that is 18 inches high empty ends up taller once the cushion goes on.
The numbers
- Seat height 17 to 19 in, floor to the top of the cushion
- Seat depth 18 to 22 in, cushion included
- Back height 12 to 18 in above the seat
- Back angle 7 to 9 degrees off vertical
- Cushion 2 to 4 in thick, allowing 2 in of compression under a sitter
- Table height 28 to 30 in
- Seat edge to table 10 to 12 in
- Seat to tabletop 10 to 12 in, measured up from the cushion
- Knee room about 10 in, cushion top to table underside, 8 in at the least
- Knee space width 24 in per seated diner
- Clearance behind 32 in with nobody passing, 36 in to edge past, 44 in to walk past

Nook planner
Find the table your corner can take, how long to make the benches, and how many people it seats. All you need is a tape measure.
Bench and table heights
That is for your table. Most guides give 17 to 19 in for a 28 to 30 in table.
How the planner works
Everyone on the bench gets 24 inches if you don’t mind touching elbows, 30 if you do. The bench back sits 18 inches from the table edge on the snug setting and 20 on the comfortable one.
A built-in bench only reaches about halfway round a round table, so the planner gives the bench half the people that table seats in a dining room, and chairs take the open side. It checks the six sizes on a standard seating chart, 30 to 60 inches. Nobody eats well in the inside corner, so we add one extra place’s worth of bench there. That one is our own rule of thumb, not a published figure.
Past a chair, the planner leaves 32 inches from the table edge to the wall when nobody walks behind it, 36 if people squeeze by, and 44 if they walk by. A walkway with no chair gets 36. Where a wall faces the table and nobody sits there, we still leave 32 inches so you can slide in and out. That last one is our call.
A table along a wall bench is 30 inches deep. For heights, the seat sits 10 to 12 inches below the tabletop, with at least 8 inches between the seat and whatever hangs under the table.
The drawing is to scale but simplified. Measure at the height the bench will sit, past any baseboard or radiator.

Banquette Seat Height and Table Height
Choose the seat and the table together. The gap between them decides whether you are comfortable, so a bench that is fine on its own can be wrong under the table you already have.
A comfortable seat is 17 to 19 inches from the floor to the top of the cushion, and a dining table is 28 to 30 inches tall. If you are not sure where to land, pair an 18 inch seat with a 30 inch table.
If you are buying a bench, the seat height in the listing is for the bare bench. The corner benches I reviewed list 18.2 to 20 inches as sold, so a 4 inch cushion lifts even the lowest of them past 19 inches once it squashes down. Either look for a lower bench and add the cushion, or keep the one you like and settle for a thin pad.
Avoid a tall seat under a low table. A 19 inch seat under a 28 inch table leaves only 9 inches to the tabletop and even less under it, so your thighs end up pressed against the underside. You will not want to stay at that table after breakfast.
Before you order, check the listing against these numbers with your cushion added. The corner benches I reviewed are compared side by side on their own page, and so are the ones with storage under the seat.
Banquette Seat Depth
Keep the seat 18 to 22 inches deep, cushion included, and lean toward the shallow end. A deeper seat sounds more comfortable, and on a sofa it would be. At a table it moves you back from your plate.
On a deep bench, a shorter adult either sits back with the table out of reach or perches on the front edge with nothing behind them. If the people who will eat there are on the shorter side, keep it close to 18 inches deep.
Of the benches I reviewed that list a depth, only the Three Posts Maniscalco goes past 18 inches front to back. The Lark Manor Eslick and Selby, the Ebern Designs Joddie and the Ophelia Deral are all shallow, so if you want depth, the Maniscalco is the one. If a listing leaves out the seat depth, assume it is short.
For room to lounge, build the box 22 inches deep and stand a 4 inch cushion against the back. With the cushion in, it sits like an 18 inch dining seat. Pull it out and you have a deeper seat to curl up in.
If you are building, measure depth from the front lip to the lowest part of the angled backrest, with no cushion on the back. If you add a back cushion, build the box deeper by its thickness. The cushion guide covers the foam and the cover.
Buying a bench instead of building one
Lark Manor EslickTwo pieces for a corner. 18.2 in high and 16.5 in deep, a bit shallow.
Lark Manor EhrhartThe one with a real back. 19.5 in high, so skip the extra cushion.
Go easy on cushions. A 4 inch one, even once it squashes down, puts any of these three too high for a 30 inch table. Heights are as listed and depths are front to back, from Wayfair listings read 8 to 10 September 2026.
Want a back as well as storage? The banquettes with storage page compares the Castlery Callie, the West Elm Shelter and one made to measure.
Banquette Back Height and Cushion Thickness
Back height and angle
Make the back 12 to 18 inches tall above the seat, and give it a slight lean. That lean adds a lot of comfort, and it gives you somewhere to sit back once the plates are cleared.
Lean it 7 to 9 degrees off vertical. That range comes from one designer’s own built-in banquettes, so treat it as a starting point.
The easy way to set it is with a digital level held against the back. Adjust until it reads 83 degrees, and you have a 7 degree lean.
Some plans give the angle as 95 degrees between the seat and the back, with the seat itself tipped back at least 5 degrees. That one is measured from the seat instead of from vertical, so pick one plan and follow it the whole way.
Cushion thickness and foam
Cushions run 2 to 4 inches thick, and a 4 inch one squashes down about 2 inches when someone sits on it. Leave that out of your math and the seat ends up 2 inches lower than you planned.
So for an 18 inch seat, build the plywood deck at 16 inches and let the foam make up the rest. Build it at 18 and put the cushion on top, and you are sitting at 20, an inch over the range.
A cushion also loses some height for good over the years, which is a separate thing from squashing under you. For that, look at the foam density. The cushion guide explains what to buy.
Every Banquette Dimension, in One Table
| Measurement | Range | What goes wrong outside it |
|---|---|---|
| Seat height | 17–19 in | Too low and you eat with your chin near the plate. Too high and your feet dangle |
| Seat depth | 18–22 in | Near the deep end, shorter people perch on the front edge to reach the table |
| Back height | 12–18 in above the seat | Under 12 and it supports nothing. Over 18 in a small room it walls off the corner |
| Back angle | 7–9 degrees off vertical | Vertical and nobody leans back. Described rather than specified, see above |
| Cushion thickness | 2–4 in | Under 2 in it is a board. Over 4 and your finished seat height moves |
| Foam compression | about 2 in from 4 in of foam | Left out of the math, the finished seat lands 2 in low |
| Table height | 28–30 in | Has to pair with the seat, not be chosen separately |
| Seat edge to table edge | 10–12 in, measured across | Farther and you lean forward to reach the plate |
| Knee clearance | About 10 in, 8 at the least | A thick tabletop or an apron rail eats into this, so ask for the clear height under the apron |
| Knee space width per person | 24 in | Under 24 and shoulders overlap |
| Clearance behind | 32 / 36 / 44 in | 32 with nobody passing, 36 to edge past, 44 to walk past |
Knee Clearance Under the Table
Leave about 10 inches between the top of the cushion and the underside of the table, and no less than 8. Measure to the underside, where your legs actually meet the table.
The height in a table listing is to the top, and a thick top with a rail under it (the apron) can eat into your knee room. Before you order a table, ask the seller for the clear height under the apron.
Take your seat height away from that number, and what is left is your knee room. A 30-inch table with a 3-inch apron over an 18-inch seat leaves about 9 inches.
If someone at your table uses a wheelchair, choose a table with at least 27 inches of clear height under it, measured from the floor.
How much banquette does each person need?
Plan 24 inches of knee space width for each person, measured along the edge of the table.
Standard spacing for dining chairs is 24 to 30 inches, so the two agree. Take 24 inches as the least you can get away with, and 30 if you have the length and like elbow room.
On an L-shaped bench, do not count the inside corner where the two sides meet. The people on either side of it want the same space for their legs, so take one seat off whatever the tape measure gives you.
Does it fit the nook?
With nobody passing behind anyone seated, leave 32 inches from the table edge to the wall. Make it 36 if someone has to edge past sideways, and 44 if people walk through.
In a corner nook the bench sits against the walls, so only the open sides need this room. That is how a nook fits into a kitchen with no space for a table and four chairs.
Measure to the wall at floor level, so the baseboard is counted. Then see which corner benches fit, with current prices.

Banquette Seating Questions
How high should a banquette seat be?
17 to 19 inches from the floor to the top of the cushion, and 18 is the safe choice. Measure it with someone sitting on it, after the cushion has squashed down.
How deep should banquette seating be?
18 to 22 inches including the cushion. Stay near the lower end unless everyone using it is tall.
How far should a banquette be from the table?
10 to 12 inches, measured straight out from the front edge of the seat to the edge of the table.
What angle should a banquette back be?
Lean it 7 to 9 degrees off vertical. Measure from vertical, because plans that measure from the seat use a different number.
Does the cushion count in banquette seat height?
Yes. Four inches of foam squashes about 2 inches under someone sitting on it, so a 16 inch deck finishes at 18 inches. Build the deck to 18 and put foam on top, and you end up at 20, an inch too high.
Can I use a standard dining table with a built-in banquette?
Usually, if it is 28 to 30 inches tall and you check the clear height under the apron rather than the height to the top.
How much space do you need for banquette seating?
32 inches from the table edge to the wall if nobody walks behind the diner, 36 if someone edges past, 44 if someone walks past. In a corner nook the bench sides are against the walls, so you only need this on the open sides.
