When I write a hat pattern, I like to make sure it can be made for just about any size head. I notice this is something not all designers do. Quite often, patterns will be for one size only (e.g. average woman’s size) and I wonder whether there is much value-added if I produce a hat in a range of sizes? Do people actually want hats scaled for babies all the way up to adults? Certainly, if a stitch pattern doesn’t allow for small grade changes, fewer sizes might be appropriate. Usually though, stitch patterns just aren’t that big or can be tweaked to accommodate patterns with a range of sizes.
Let me know in the comments below, I’d love to hear what you think.

Here is a table of my existing hats (7 different patterns) and the sizes they are written for.

On average, the circumference of a head of a Baby (Toddler, Child, S Adult [Teen], M Adult [Woman], L Adult [Man]) is 14 (16, 18, 20, 22, 24) inches or 35.5 (40.5, 46, 51, 56, 61) cm
