What Size Pillow Insert Do You Need for a Cover? A Simple Sizing Guide
A pillow cover looks best when it is plump, with crisp corners and no wrinkles. That comes down to one decision: the size of the insert. This guide answers what size pillow insert for a cover you need, with a simple rule, a chart for the sizes in our shop and a few tips for a fuller look.
The simple rule
A common design rule is to choose an insert that is one to two inches larger than the cover. A slightly oversized insert fills the corners, so the pillow looks full instead of limp. For example, an 18 by 18 inch cover works well with a 20 by 20 inch insert.
Sizing chart for our covers
The A Fresh Start Feels Good pillow cover comes in seven square sizes. The listing notes a size variance of plus or minus half an inch, and the insert is sold separately.
| Cover size | Insert to look for |
|---|---|
| 14 by 14 inches | 16 by 16 inches |
| 16 by 16 inches | 18 by 18 inches |
| 18 by 18 inches | 20 by 20 inches |
| 20 by 20 inches | 22 by 22 inches |
| 24 by 24 inches | 26 by 26 inches |
| 26 by 26 inches | 28 by 28 inches |
| 28 by 28 inches | 28 to 30 inches, depending on what is available |
Prices run from $22.99 to $36.99 depending on size. If you cannot find an exact size, choose the closest one that is slightly larger rather than smaller.
About the cover
- 100% spun polyester that is shape-retaining and wrinkle-resistant.
- A double-sided print, so the design looks the same on both faces.
- A concealed zipper with a metal pull for a clean edge.
- A pre-constructed square shape, ready to slip onto standard square inserts.
Tips for a fuller pillow
- Push the insert into the corners before you zip the cover shut.
- Give the pillow a gentle karate chop across the top for the classic look.
- Fluff the insert regularly so it keeps its shape.
- Mix sizes on a sofa, such as two 18 inch pillows and one 24 inch, for a layered look.
Insert fills: poly-fill vs feather
Poly-fill inserts are lightweight, easy to wash and hold their shape. Feather and down inserts feel softer and drape more, but often cost more and need more fluffing. Choose the fill that suits how you use the pillow.
Care for the cover
The care instructions say to remove the cover from the pillow, pre-treat stains with a soft cloth or brush soaked in warm soapy water, then machine wash at a maximum of 40C on a normal cycle. Do not bleach, do not tumble dry, and iron, steam or dry on low heat only. Fluff to reshape when you put it back together.
Frequently asked questions
Should the insert be bigger than the cover?
Yes. One to two inches larger gives a fuller, neater pillow.
Does the cover come with an insert?
No. The insert is sold separately.
Can I use a rectangular insert?
The cover is square, so a square insert gives the best fit.
