# How to Calculate Stitches in Knitting

Let’s be honest: knitting from patterns is awesome. There are so many amazing designs out there that you could knit from patterns for the rest of your life and never get bored. But equally awesome is pushing yourself to create your own designs. If this sort of experimentation is your jam, hats are a great place to start. Sure, there’s a bit of math involved in all knitting, and designing your own hats is no exception. Good news, though: the math is fairly straightforward, and even if things go off the rails, hats aren’t *that* painful to rip and reknit (practice makes perfect, or so they say).

## How to Knit a Hat From Scratch

Now you need to figure out how many stitches per inch you’ve got. Use a ruler to measure how many stitches fit within 1″. Write that number down.

### 3. Math Time

Multiply your head circumference from Step 1 by the number of stitches per inch in Step 2. If you’re going straight stockinette or garter stitch, this is the number of stitches you’ll cast on. If you’re venturing into fancy stitch pattern territory, you’ll need to take that number and round it to the nearest multiple of your stitch pattern (if you’re doing 1×1 rib, for example, make sure you’re casting on an even number of stitches).

### 4. Decrease the Crown

Knit your hat until it’s the length you measured in Step 1. Then, time to decrease. You get to play designer again here. The basic principle is that you divide the number of stitches you have into even sections, and work decreases in each of those sections every other round. Stitch markers are your friends here, and will help you keep track of where you’re placing your decreases. Once you’re down to a reasonable number of stitches, thread your tail through the live stitches, and cinch the crown up. Now, there’s just one more decision… to pom, or not to pom. (You should probably pom.)
