Pillow inserts may be hidden, but the right size makes all the difference. This guide will walk you through the best sizing practices for a polished look.
The Golden Rule
Square pillows: always size up 1–2 inches. Lumbar pillows: match the insert size to the cover.
Step-by-Step Sizing Guide
1. Measure your pillow cover seam-to-seam.
2. Add 1–2 inches for square covers to find the right insert.
3. For rectangular lumbars, use the same size insert.
Common Insert Sizes with Cover Pairings
- 18x18 cover → 20x20 insert
- 20x20 cover → 22x22 insert
- 22x22 cover → 24x24 insert
- 14x20 cover → 14x20 insert
