Making Sense of Pillow Sizes
Getting it straight from Pillow Decor
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 and are almost always rounded up to the nearest whole inch.
Looking at the example below of this elegant 20"x20" 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 20"x20"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 inches. 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 inches.
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 20.2"x20.2", it may still be called a 20"x20" 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. If your old pillow inserts seem flat and lumpy, maybe all you need are some new feather/down inserts or polyfill inserts to bring your pillows back to life.
