MEASURING GUIDE
How to measure foam for your cushions
Getting the size right is the most important step. Here's how to measure the most common cushion shapes. Measure in inches. Not sure? Bring the old cushion or its cover to our shop.
THE BASICS
Three measurements
Almost every piece of foam comes down to three numbers. Write them in this order: thickness × width × length.
- Thickness How tall the foam is.
- Width Side to side, across the front.
- Length Front to back (also called depth).
COMMON SHAPES
Find your shape
T-cushion
Sofa and chair seats with “ears” that wrap around the front of the arms.
- Width across the front (the widest part)
- Width across the back
- Depth of the ears, from the front edge to where the T steps in
- Total depth, front to back
Plus the thickness.
Round
Stools, bar seats and round chair pads.
- Diameter: straight across, through the center
Plus the thickness.
Wedge
Slanted back cushions and bed wedges.
- Thickness at the tall end
- Thickness at the short end
- Length
Plus the width, side to side.
Any other shape
Boat, RV and odd-shaped cushions are easiest with a paper template. For boats and patios, ask for our outdoor and marine-grade foam.
- Lay paper or cardboard on the seat and trace the outline.
- Mark which edge is the front.
- Write the thickness on it and bring it to the shop.
TIPS
Get it right the first time
- Measure the cover, not the old foam. Old foam gets flattened and shrinks over time. Measure the cushion cover from seam to seam.
- Replacing a missing cushion? Measure the space it fills: the seat or frame, side to side and front to back.
- Measure twice. Check every side. Older furniture isn't always perfectly square.
- Want a fuller, rounded look? Ask us to wrap your foam in Dacron. Just let us know when you order.
- Still not sure? Bring the old cushion or cover in, along with a photo of the furniture.
