If you're looking to buy a new hat, you need to know how to find your hat size. Head size actually can change over time, due to things like weight loss, wight gain, or age. Hair style can affect the size of hat you need, too, so you always want to measure before buying any hat that isn't adjustable.
- A soft plastic or cloth tape measure (not the metal kind that won't lie smoothly against your head!), OR
A piece of string and a ruler
- Measure the circumference of your head: This may be tricky, so you might want to have someone help. Measure about a half inch above the ear, and over the eyebrows. Basically, where the hat will sit. Don't pull too tight, or the measurement will be too small. If you don't have a tape measure, just use a piece of string. Mark it, and measure it against a ruler. You will want to measure at least twice to make sure you get the right number. Round to the nearest 1/8 of an inch.
- Determine your size: A Medium sized hat, or a size 7, is about 22 inches (or 56 centimeters). To find your size, look at a hat sizing chart.
- Determine your hat type: Different types of hats use different size scales. The common types are Fitted (such as a Stetson or Cowboy hat), Easy Fitted (such as a non-adjustable baseball cap), or Stretch Fitted (such as a knit cap). Fitted hats use number sizing, Easy Fitted uses Small, Medium, Large (S, M, L) sizing, and Stretch use S/M, M/L, L/XL sizing. One Size Fits Most generally fit 22" – 23.5".
