Bottom-Up Hat Calculator

Designing a bottom-up hat is quite simple when you use these formulas. Unlike with scarves or cowls, however, you’ll need to do a little math to distribute the decreases that shape the crown. See Determining Stitch Count for Final Round on page 70 for tips on how to decrease evenly for the crown.

The fields F, G, and H are optional. You need to fill these in only if you are working a stitch pattern with known row/round and stitch repeats per unit of measurement.

Fields marked with * are required.
