Some people say that if you're buying an adjustable, fitted cap, you don't need to measure your head. However, it's still a good idea, particularly if you intend to buy a cap online and can't try it on first. You don't want to run the risk of it being too tight and leaving a red band around your forehead or being too loose and flying off with a strong gust of wind. Even if you are at a shop and have the chance to try fitted caps on, it's always best to know your exact size, ask for that and then judge how the cap feels, as such a process reduces the margin of error. There are two systems for measuring hats and caps -- metric and British hat sizes.
Things you need
- Tape measure
Wrap a tape measure around your head, 2.5 cm (1 inch) above your eyebrows. Make sure that the tape measure is neither too tight or too loose around your head. Record the circumference of your head in centimetres on a piece of paper. Round up that measurement to the nearest whole number to get you metric cap size.
Look up your possible hat size based on the following chart. If your measurement is 52 cm to 55 cm (20 1/2 inches to 21 5/8 inches), your hat size is a Small or ranges from 6 3/8 to 6 3/4. If your measurement was 56 cm to 57 cm (22 inches to 22 3/8 inches), your hat size is a Medium or ranges from size 6 7/8 to 7. If your measurement is 58 to 59 cm (22 5/8 inches to 23 inches) your cap size is a Large or ranges from size 7 1/8 to 7/14. If your measurement is larger than 59 cm (23 inches) your size is Extra Large.
Try on several sizes in your designated size range. Decide if you like your hat to be on the snugger or looser size. Pick a size the fits your head securely but is not uncomfortable. Make note of the size. The size you like best not only fits your head but also your personal preferences.
Tips and warnings
- Beware, American hat sizes are 1/8 bigger than UK sizes, so a 7 1/8 in the UK is a 7 1/4 in the US.
