Hats are an important accessory in any man’s wardrobe. They complete an outfit and have practical purposes. You can wear a baseball cap to support your favourite team, a fedora to stay warm and look fashionable in winter or a summer hat to shade yourself from the sun. Before you shop for hats, you must determine your exact hat size. Buying the correct-sized hat will ensure a comfortable fit and avoid unsightly hat marks on your head.

  1. 1

    Stand in front of a mirror and place the end of the measuring tape on the middle of your forehead, above your nose.

  2. 2

    Wrap the tape around the back of your head, making sure to place the tape across the wide part of the back of your head and 1/8 of an inch above your ear. Then bring the tape to the middle of your forehead to meet the other end.

  3. 3

    Determine the measurement by looking at the measuring tape in the mirror.

  4. 4

    Measure your head several times to avoid error, and then write down the head measurement.

  5. 5

    Compare your head measurement to the sizing chart (see Tips) to determine what hat size you wear.

Tips and warnings

  • Head Measurement in Inches = Hat Size: 21 1/8 = 6 ¾ (S); 21 1/2 = 6 7/8 (S); 21 7/8 = 7 (M); 22 1/4 = 7 1/8 (M); 22 5/8 = 7 ¼ (L); 23 = 7 3/8 (L); 23 1/2 = 7 ½ (XL); 23 7/8 = 7 5/8 (XL); 24 1/4 = 7 ¾ (XXL); 24 5/8 = 7 7/8 (XXL).
  • If your head measurement does not correspond with the sizing chart, it is customary to round your head measurement up a quarter of an inch.
  • When measuring your head, do not wrap the measuring tape too tight. If the tape is too tight, your hat will also be too tight.
