Need help sizing your crochet animal hat?

Getting the right fit is one of the most important parts of making a crochet hat, especially for animal hats with ears and face details.

If you’re unsure about head circumference, hat height, negative ease, or which size to make, check out my full crochet hat sizing guide. It walks you through the sizing basics step by step and makes it easier to choose the best fit from baby to adult.

You’ll learn:

How to measure head circumference correctly — so you pick the right size
How to choose the right crochet hat size (baby to adult) — using your measurements
How hat height affects fit and comfort — so it doesn’t feel too short or too tall

How to adjust a crochet hat pattern — if your hat feels too tight, loose, or short

If your hat feels too tight, too loose, or too short, the sizing guide will help you make simple adjustments with confidence.
