Crochet Hat Pattern Generator

Why this writes out every round instead of just a stitch count

A cast-on count and a decrease plan tell you the shape, but a real pattern tells you exactly what to do round by round — including the specific decrease stitch for your chosen stitch pattern, and the running stitch count after every round so you can check your work as you go. This generator writes that full pattern out, the same way a designer would, tailored to your exact gauge and size.

Bottom-up or top-down, your choice

Use the Construction menu to pick either method. Bottom-up chains the full brim circumference first, works straight up through the body, then decreases at the crown to close the top. Top-down starts with a magic ring at the crown, increases out to the full circumference, then works the body and brim last, so you can try the hat on as you go. Every round is joined and turned the same direction (or worked in a continuous spiral, if you prefer no join at all; just skip the "join, ch 1" instructions and keep working around).

Swatch first, then trust the pattern

This pattern is only as accurate as the gauge you enter — work an actual swatch in your chosen stitch, measure it after washing/blocking, and use that real number rather than a guess. A gauge that's off by even one stitch per 4 inches can shift the finished hat by a meaningful amount over a full head circumference.
