7 1/2 hat size in cm and inches
Fitted hat sizes are the diameter of the head in inches. 7 1/2 × 3.1416 gives 23.56 inches of head circumference, which is 59.8 cm. New Era lists 7 1/2 as 59.6 cm, so expect brands to round by a few millimetres. In the UK the same hat is a 7 ⅜, and in Europe it is a size 60.

Is 7 1/2 small, medium or large?
In letter sizing 7 1/2 is usually extra large (XL). Stretch-fit and adjustable caps use ranges, so the same head can be a different letter at each brand:
- New Era 59FIFTY: 7 ½
- New Era 39THIRTY: M/L
- Flexfit: L/XL / XXL
- Nike: M/L / L/XL
- Stetson: X-Large
- Melin: Classic
- Kangol: XL
How common is a 7 1/2 hat?
7 1/2 is above average. It is still widely stocked, but some one-size-fits-most caps will feel snug, so a stretch-fit L/XL or a true fitted cap is the safer choice.

Fit tips
- If you measure between 7 1/2 and the next size up, choose the larger size for fitted caps and felt hats.
- A stretch-fit range that includes 7 1/2 will fit, but pick the range where 7 1/2 sits in the middle when you can.
- Measure again before you buy. A haircut or a new hairstyle can change your size by an eighth.
