The Secret Recipe for a Knitted Baby Hat That Fits Every Time

Whether you're knitting a hat to donate to a baby in the NICU or to a loved one, hats make a great practical gift for babies and new parents. One of the trickiest parts of baby knitting is sizing. Read on for baby hat knit sizes.

To help you make baby hats in a variety of sizes, here's a list to help you decide which hat size to make so you don't make your hat too big or too small when winter hits.

Average baby head size by size

Premature infant head size: 9 inches in circumference and 4 inches in height

Neonatal size: 11 inches girth, 5 inches high

0-3 months size: 13" girth, 6" high

3-6 months size: 16" girth, 7" high

6-9 months size: 18" girth, 7.5" high

12 months size: 20 inches girth, 8 inches high

24-4T size: 21 inches in circumference, 8.5 inches in height

Using the sizing information above, here is the formula to determine how many stitches you need in a round to knit this baby hat size:

Circumference (inches) x stitches per inch = number of castings

For babies due in the spring, wear a size 6-9 months this year, or a size 18-24 months next year.

For a baby due in the summer, knit a hat that is 3-6 months old this year, or 18-24 months old next year.

For babies due in fall, knit 0-3 or 3-6 month hats this year, or 24 months next year.

For babies due in winter, knit hats in sizes 0-3 or 3-6 this year, or 12 months or 24 months next year.

The above is a brief list of some baby hat knitting sizes. If you are still not sure what size baby hat to buy or want to customize baby hats of different sizes, please contact us.
