For a full and plump look choose an insert 2” larger than the size of the pillow cover. For example,if you purchase a pillow cover that's 18x18, purchase a pillow insert measuring 20x20.
You’ll also need to choose the insert material...
Polyester is the most affordable insert option. It gives a solid, full shape to the pillow, but is not easily re-shaped. If you like the look of a karate-chopped pillow (and who doesn’t?) this material isn’t for you. Polyester tends to flatten with time and it can be difficult to remold the material and regain that initial nice, full shape.
Down inserts will cost a little more money, but they will look full for years to come. Down pillows might flatten and lose shape when laid on or leaned against, but they can easily be reshaped. Keep in mind, some people are allergic to down feathers, and you will likely have a feather escape or poke through the fabric from time to time. To prevent these issues you can purchase an allergy control cover to place on the pillow before putting on the decorative cover.
Down alternative gives you the best of both worlds. It’s more affordable than down, more malleable and luxurious feeling than polyester, and comes without the risk of allergy or loose feathers.
