Measure the head if you can. Heads of one age differ by inches, and a band made to a measured head fits better than one made to an age.
The head sizes are the rows of our hat size chart: what hat size charts say, from the smallest to the largest figure they give.
The band length is worked out from the head size: 1 to 2 inches (2.5 to 5 cm) less than the head. It is the distance around the finished band, measured before the band is stretched.
Centimeters are worked out from the inches and rounded to a whole centimeter.

Make the band shorter than the head is round. Crochet fabric stretches, so a headband or ear warmer is made 1 to 2 inches (2.5 to 5 cm) less around than the head and stretches to fit.
An ear warmer for a child or an adult is about 4 inches (10 cm) wide.
Work from the head you are making for when you can: measure around it, then take the band length from that number and not from an age.

How long should a headband be for an adult?: For a woman, hat charts give a head of 21 to 23 inches (53 to 58 cm), so the band is 19 to 22 inches (48 to 56 cm) long. For a man, the head is 22 to 24 inches (56 to 61 cm) and the band 20 to 23 inches (51 to 58 cm).
How long do I make a headband for a 22 inch head?: 20 to 21 inches (51 to 53 cm): 1 to 2 inches less than the head, because the band stretches.
How wide should an ear warmer be?: About 4 inches (10 cm) for a child or an adult.

Why is the band shorter than the head?: Because crochet fabric stretches. A band made 1 to 2 inches (2.5 to 5 cm) shorter than the head stretches to fit it.
How do I make a headband longer or shorter?: It depends on which way the band is worked. In a band worked along its length, add or take away starting chains. In a band worked back and forth across its width, work more rows or fewer, until it is long enough.
Where do these head sizes come from?: They are the rows of our hat size chart, which also has a size for a preemie and heads as measured for babies and toddlers. Our suggestion
