A 7½ hat fits a head circumference of about 23½ inches (59.8 cm), covering heads from roughly 23.4 to 23.8 inches (59.3–60.3 cm). It is where "big head" sizing starts: the top of most one-size caps and the bottom of MONGO's range.
7½ hat size in inches and cm
| Hat size | Head (inches) | Head (cm) |
|---|---|---|
| 7⅜ | 23⅛ (23.0–23.4) | 58.8 (58.4–59.3) |
| 7½ | 23½ (23.4–23.8) | 59.8 (59.3–60.3) |
| 7⅝ | 24 (23.8–24.2) | 60.8 (60.3–61.3) |
The maths: 23.56 in ÷ 3.1416 = 7.500, which is 7½ (written 7 1/2 on a lot of labels). Full range on the hat size chart.
How common is a 7½ head?
In the US Army's ANSUR II survey (4,082 men and 1,986 women measured), the median head circumference was 57.4 cm for men and 56.0 cm for women, and the 95th percentile was 60.1 cm for men and 59.7 cm for women. A 7½ head (59.3–60.3 cm) sits right around that 95th percentile for men. At the top of the band, you're bigger than about 95% of men; for women, a 7½ sits right around the 95th percentile too.

Do one-size caps fit a 7½?
Usually, but snugly. A 7½ is inside most one-size ranges, but close to the end of them. New Era's 9FORTY stops at 23⅞ in, just ⅜ inch above you. Expect to be on the last snap or two, and expect a standard crown to sit a little high.
Does MONGO fit a 7½?
Yes. 7½ is the bottom of MONGO's range (7½–8½, 23.6–26.7 in / 60–68 cm), so you'll be on the tighter end of the snapback.
Who it suits: 7½ heads who are tired of the last-snap squeeze or caps that perch on top. Our deeper crown lets the hat come down to where it should sit. If a regular cap fits you comfortably on a middle snap, though, you don't need us.
Try the XL Performance Snapback 2.0 ($59.99, 7 colours) or the XL Foam Trucker ($44.99). Free US shipping and a 30-day fit guarantee: if it doesn't fit, we cover the return shipping.
