About ease in knitting

Ease is the difference between your actual body measurement and the finished garment measurement. Positive ease means the garment is larger than your body — it hangs loosely. Negative ease means the garment is smaller — it stretches to fit and clings to the body.

Common uses

  • Find the finished measurement to target when choosing a pattern size
  • Compare ease across different fit styles before casting on
  • Understand why a pattern might be knit in a size larger than your measurements

Always check a pattern's schematic for the finished measurements and compare to your body measurements plus desired ease before choosing your size.
