Standard Pillow Insert Sizes: A Complete Guide

Standard pillow insert sizes take the guesswork out of shopping. Whether you’re styling a sofa, sectional, or bed, knowing the core dimensions makes it easy to create polished arrangements.

Most Common Standard Sizes

Here are the most widely used pillow insert sizes:

  • 16x16: Small chairs, kids’ rooms
  • 18x18: Everyday sofas, layering
  • 20x20: Sectionals and large sofas
  • 22x22: Designer look, fuller cushions
  • 24x24: Oversized, lounge-worthy spaces
  • 12x20: Lumbars for sofas, beds, and chairs

Why Standard Sizes Work

Because these dimensions are widely available, you can easily replace or upgrade inserts without worrying about fit. They’re also versatile for layering and mixing across furniture types.

Designer Recommendations

On sofas, we recommend starting with 22x22 inserts paired with 20x20 covers for a full look. Add a lumbar like 12x20 to create variety and dimension.
