How to Measure a Round Cushion
To measure a round cushion, run a tape straight across the centre of the seat at its widest point to get the diameter, measure a second diameter at 90° to the first, and decide the thickness. If the two diameters match, the cushion is round; if they differ, it is an oval. For a papasan, measure the inside diameter of the bowl frame, not the old cushion.
Foamera makes made-to-measure foam cushions and sells them online through TURKEX LLC. Sizes can be entered in inches or centimetres on each product page.
Diameter, radius or circumference?
Use the diameter: the straight distance across the circle through the centre, edge to edge. You do not need the radius or the circumference. Diameter plus thickness is all a round cushion needs.
How do I measure each round shape?
| Shape | Measure | Product |
|---|---|---|
| Round seat or stool | Diameter through the centre, a second diameter at 90°, thickness | Outdoor Round Cushions |
| Papasan bowl | Inside diameter of the bowl frame, thickness | Outdoor Papasan Cushions |
| Half-round (D-shape) | Width along the straight edge, depth from the straight edge to the top of the curve, thickness | Half Rounded Cushions |
| Oval | Long axis and short axis through the centre, thickness | Ask us |
How do I measure a papasan cushion?
Measure the inside diameter of the papasan frame across the middle, from rim to rim. Measure the frame rather than the old cushion, which has usually compressed over time. Because a papasan cushion should fill the bowl, send the inside frame diameter as it is.
Should the cushion be smaller than the seat?
Send the exact seat diameter without subtracting anything; we confirm the allowance during the free size check.
What should I send?
- Both diameters and the thickness, in one unit, inches or centimetres, for example 18 in (46 cm) across and 2 in (5 cm) thick. This example is only an illustration.
- A photo of the seat from above with the tape across the centre.
