For homes with kids, smaller pillows are preferred. Each of these sizes will have many pillows available for support, comfort, and decorating a space.

To get an accurate measurement, here’s what to do. Take the inserts out before measuring your pillows if your covers have removable inserts and have zippers.

Alternatively, you can pinch the pillow’s two top corners and then pull the top seam tightly all while holding the throw pillow beside a measuring tape if the pillow is sewn up and the insert isn’t removable.

You might want to get help from another person to do this. But if you cannot pull the pillow straight, you can just add some length to the measurement. However, ensure that you round up to a ½-inch increment.

For smaller than 18 by 18 pillows and lumbars, inserts that are one inch larger will work better than those larger by two inches. If you have extra large throw pillows, like 24 by 24s, inserts that are larger by 3 inches than the cover will work best.

These sizes also work well for standalone chairs. The 12 by 20 inches rectangular pillow, in particular, can offer excellent aesthetics when used alongside other throw pillows. A 12 by 20 inch pillow can offer a good layering solution in front of smaller 18-inch or 22-inch square throw pillows, too.

However, some are confused between lumbar and bolster pillows. The latter pertains to a cylinder shape pillow that has round ends, while a lumbar pillow is rectangular in shape. But then, if a rectangular shaped pillow is higher than 14 inches, it might not be able to provide lumbar support for most people, except for taller users.

Thus, a pillow with a size of 16 by 24 inches is not anymore a lumbar pillow in that it’s now very broad for offering full back support. Nevertheless, a larger rectangular pillow is still a good choice for larger sectionals, as they can add aesthetics and offer backrest. See more types of pillows here.
