Men’s and women’s beanies

Beanies are unisex. A men’s beanie is often cut deeper so it can be worn cuffed or slouchy, while a women’s beanie may be shorter or more fitted. If your head is 60 cm or more, look for L/XL or extra-long beanies.

Making your own beanie

If you knit or crochet, make the beanie smaller than the head so it stretches into place. The knit and crochet charts give finished sizes by age.

Fit tips

  • A beanie should cover the tops of your ears and stay put without pressing on your forehead.
  • Ribbed beanies stretch the most. Cable and colourwork beanies stretch the least, so size up for those.

How to measure your head

  1. 1 Use a soft tape measure, or a string and a ruler.
  2. 2 Wrap it around your head where the hat will sit: about 1 cm (⅜ in) above your ears and across the middle of your forehead.
  3. 3 Keep the tape level and snug, not tight. Do not pull it in.
  4. 4 Read the number where the tape overlaps. Measure two or three times and use the largest value.
  5. 5 Type the number into the calculator, or find it in the chart.
