This works for any yarn and any size head. You need to do a little bit of maths first, then fill in the blanks below with your specific numbers.
Yarn gauge (stitches per inch or cm) ___
Head circumference (in or cm) ___
Stitches per inch x head circumference rounded up to the nearest multiple of 8 gives you the number of stitches to cast on.
For example, if the ballband says the yarn has 22 sts to 4in (or 10cm) that’s 4.5 sts per inch. So if the head is 21in around (small adult) then you get 94.5 sts. Round up to the nearest multiple of 8 and you get 96 sts to cast on.
Head circumference divided by two gives you the ribbing length.
Cast on __ sts. I recommend using Jeny’s Stretchy Slipknot Cast-on as it really is super stretchy and well worth the extra effort.
Row 1: *P2, K2; rep from * to end of round (i.e. 2×2 rib starting with purl).
Repeat this row until your hat ribbing is __ in/cm long. This should give you enough hat to cover your ears or turn up a brim.
Row 1: *P2, K2, P1, k2tog, K1; rep from * to end.
Row 2: *P2, K2, P1, K2; rep from * to end.
Row 3: *P2, K2, k2tog, K1; rep from * to end.
Row 4: *P2, K4; rep from * to end.
Row 5: *P2, K1, k2tog, K1; rep from * to end.
Row 6: *P2, K3; rep from * to end.
Row 7: *P2, k2tog, K1; rep from * to end.
Row 8: *P1, k2tog, K1; rep from * to end.
Row 9: *k2tog, K1; rep from * to end.
Row 10: *k2tog; rep from * to end.
If you cast on more than 80 sts you may wish to repeat row 10 one or two more times before casting off. Aim to have about 5-8 sts when you finish.
Cast off by drawing the yarn tail through the remaining live stitches and pulling tight.
Newborn babies’ heads start at about 9in for a small preemie or 13in for a full-term baby while adult heads are typically 20-24in. As this rib pattern is very stretchy it will fit heads both larger and smaller than the size you’re aiming for so round up a little and don’t worry too much.
Obviously, the suggested length given here is a rough estimate. Turn-up hat brims are cute on pretty much any hat, and can be any length so if in doubt go long.
If you want to be more precise, measure the head in question from ear to ear over the top of the head, starting and finishing where you want the hat to come down to (e.g. just below the ears). The crown shaping takes about 10 rows, so you can use your row gauge to calculate how long to make a particular length hat as follows:
Over the top measurement divided by two = total hat length (in or cm)
Total hat length (in or cm) x rows per in or cm = total rows
Total rows – 10 = rows of ribbing needed before crown shaping
For example, if your head is 14in from ear to ear, your total hat length is 7in. Let’s say your ballband row gauge is 28 rows to 4in or 7 rows per in. 7×7 = 49 total rows. 49-10 is 39 rows of ribbing required before starting the crown shaping for a hat with no turn up.
