How to Measure a Bench for a Custom Cushion
How to measure dining benches, entryway benches, and window seats for a custom cushion that fits edge to edge.
On this page
A good bench cushion makes a hard seat inviting. Whether it sits at the end of a dining table, by the front door, or in a sunny window seat, a cushion that fits edge to edge looks built-in and feels far more comfortable. Measuring a bench is straightforward, but a few details make the difference between a cushion that fits and one that almost fits.
Quick answer: Measure the bench seat edge to edge for length and front to back for depth. For a bench between walls, measure wall to wall at the front and the back. If those numbers differ, order a trapezoid. Choose 2″ to 3″ for dining benches and 3″ to 4″ for entryway, garden and window benches.
Know Your Bench Type
Different benches call for slightly different approaches.
- Freestanding benches such as dining or entryway benches usually have open ends. The cushion should match the seat top closely.
- Window seats and built-ins sit between walls or cabinetry. The cushion needs to fill the space without being squeezed.
- Benches with arms or backs have edges the cushion must fit around, so note where they sit.
How to Measure a Bench
- Clear the seat. Remove any old cushion, pillows, or items so you can see the full surface.
- Measure the length. Measure from one end of the seat to the other along the front edge. For a window seat, measure wall to wall.
- Measure the length again at the back. Walls and built-ins aren't always perfectly square. If the back length differs from the front, note both.
- Measure the depth. Measure from the front edge of the seat to the back wall or back rail. Take this at both ends and in the middle.
- Note corners and cutouts. Look for rounded corners, angled ends, posts, or trim that the cushion must fit around. Measure each one and sketch it.
- Decide on thickness. Measure how much clearance you have under a window sill, a tabletop, or an arm, so the cushion doesn't sit too high.
Measure in inches and round to the nearest quarter inch.
Window Seat Tips
Window seats are where careful measuring pays off most. Because the cushion sits between two walls, take the smallest of your length and depth measurements as your guide. A cushion that is a touch snug drops in neatly, while one that is too big will bow up in the middle.
If your window seat is angled, as in a bay window, make a paper template. Lay paper across the seat, press it into every corner, trace the outline, and then measure the template. Note the angle of each end.
Dining and Entryway Bench Tips
For a freestanding bench, most people prefer a cushion that matches the seat top or sits just inside its edges. That keeps the wood or frame visible as a clean border and prevents the cushion from hanging over.
Think about how the bench is used. A dining bench is pulled in close to the table, so check that the cushion plus a person's legs will still clear the tabletop. A thinner cushion often works best here. An entryway bench is used for quick sits to put on shoes, so a firmer cushion that holds its shape is a practical pick.
Choosing a Thickness
Our bench cushions can be made up to 120 inches long and from 2 to 8 inches thick, which covers everything from a slim dining pad to a deep, lounge-style window seat.
- Around 2 to 3 inches is typical for dining benches, where table clearance matters.
- Around 3 to 4 inches works well for entryway and hallway benches.
- Around 4 inches and up suits window seats and reading benches where you want to settle in.
Foam and Fabric
High Density foam gives a medium feel and holds up to frequent use. Luxury foam is firmer, which suits thin dining pads. Super Soft foam is for back cushions only, so use it for window seat backrests rather than the seat. For a bench on a porch, deck, or patio, Dry Fast foam drains water and suits outdoor use.
For fabric, Sunbrella is a solution-dyed acrylic that holds its colour in the sun and resists mildew, which makes it a natural fit for sunny window seats and outdoor benches. Indoors, you can also choose Warwick fabrics, velvet, or faux leather. Every cover is zippered.

Frequently asked questions
Should a bench cushion overhang the edge?
No. For an open bench, match the seat top exactly or set the cushion in slightly at each end. An overhang catches on legs and looks untidy. For a bench between walls, give us the exact wall-to-wall size and we cut to it, within ±0.5″.
How do I measure a bench with rounded corners?
Measure the full length and depth, then measure the radius of each corner or trace the corner on paper. Mention rounded corners when you order so the foam and cover follow the shape. A template works best for curves. Square corners are the default.
Can a long bench have one cushion or should it be split?
Bench cushions can be made up to 120″ long in one piece. For long built-ins, two or three shorter cushions are often easier to lift, wash and fit around corners, and they wear more evenly. Match the joins to any supports or cabinet doors below. See window seat cushions.
Can I add ties to a bench cushion?
Yes. Ties in matching fabric come standard, and Velcro is available on request. Ties work best on benches with legs or back posts. Build yours in the bench cushion builder and choose the tie positions as you go. Shipping in the US is free.
