Best Way to Size a Crochet Hat

Honestly, the best way to size a hat is to measure the person’s head that the hat is for.

To get the head measurements, use a sewing tape measure and measure the various areas of the person’s head for the pattern.

In general, the crochet hat circumference is about 1 inch smaller than the head circumference. This allows for the hat to fit on someone’s head without it falling off. Also, most crochet hats will have about an inch of stretch.

However, it is hard to get everyone’s hat size, especially if you plan to make hats for craft shows and presents. Measuring is out of the question.

So what do you do? Use a general sizing guide.
