Common Standard Throw Pillow Size Mistakes to Avoid
Throw pillows of the wrong size can make furniture look unbalanced.
Using too Small Pillows by Fat or Tall People
For back support, fat or tall people should use a throw pillow that is compatible with their body size. You must ensure that a throw pillow fits comfortably on your back when you use it for back support. When you spend a long time on an unsupportive pillow, you run the risk of bending your backbone.
Too Small Size for Large Sofa
Small pillows can make a large sofa feel empty and reduce its attractive look.
Using Inconsistent Sizes and Colors
An arrangement of throw pillows can look attractive when they are all of different sizes and have matching colors. But if the size is random or is not coordinated well, and the color does not match the bed or sofa, then it can appear inappropriate.
Ignore the Insert-to-cover Ratio
Many people do not understand the importance of the insert-to-cover ratio. A common guideline for square pillows is to use a 2″ larger insert than the pillow cover to maintain shape and firmness levels. For example, a 20″ insert is needed for an 18″ cover. For lumbar throw pillows, choose an insert 1”-2” longer than the pillow cover to prevent it from sagging at the end.
Too Many Throw Pillows on a Small Mattress or Bed
Using more throw pillows for a small bed or mattress to enhance your room’s beauty is the wrong idea. Select the number of pillows according to the mattress or bed size.
