How to size a crochet hat? Everyone’s head varies in size. How does one go about crocheting hats? There are a few different ways to answer these questions: one answer, a crochet hat size chart. Keep reading to check out the chart (with optional printable) and other options.
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.
