How to choose the size of pillows?

If you are unsure of what size of pillows to order, here is a brief explanation of pillow measurements that may help.

The most important thing to remember is that pillow dimensions always refer to the pillow cover's width and length while lying flat unstuffed. The measurements are taken along the seams from corner to corner Shop 16x16 Throw Pillowsand are almost always rounded up to the nearest whole inch.

Looking at the example below of this elegant 20x20 Sunbrella outdoor fabric pillow, you will notice that the actual measurements of the cover lying flat unstuffed are 19.3 x19.3. The dimensions of this pillow are rounded up and it is therefore classified as a 20x20 pillow.

Now, if you look at the same pillow cover stuffed with a polyfill insert (image on the right), you will notice that if you were to take a straight measurement from corner to corner, the width and height would be closer to 18. Furthermore, if you were to take a straight measurement across the center of the pillow (as shown by the distance between the red lines), the width would be closer to 16.2.

Measuring Pillows

These of course are just rough guidelines but hopefully you get the idea. Keep in mind that the measurements might not be rounded up in size if the dimensions are just a tiny bit bigger than the nearest whole inch. For example, if a pillow measured 20.2x20.2, it may still be called a 20x20 pillow. In general, the dimensions should be accurate within 0.7 of the measurements given.

When you are considering pillows for your sofas, chairs or beds, keep this sizing explanation in mind. Many people make the mistake of holding a tape measure across the center of a stuffed pillow and then assume that this dimension is the correct measurement of the pillow. If they order pillows based on this measurement, the chances are they will be surprised to find that the pillows they receive are actually much smaller than they wanted. The most common sizes of pillows for sofas are 18"x18" and 20"20". However, larger sofas and sectionals, especially those with deep seats or high backs, may be better off with 22"x22" or even 24"x24" pillows.

If you are trying to measure your pillows at home and your covers have zippers and removable inserts, take the inserts out before you measure your pillow. If your pillow is completely sewn up and you cannot remove the insert, pinch the two top corners of the pillow and pull the top seam as tight as you can while holding it next to a tape measure. If you cannot pull it completely straight, then add a little length to your measurement (usually 1/2 inch) to get an approximate size. You'll probably be pretty close.
