Women’s Hat Sizes

In general, women’s hats are sized in one size fits most sizes or OSFM. This means that the style is manufactured in a single size with the adaptability to suit various head sizes ranging from 21.5 inches to 22.25 inches in circumference.

With that being said, actual hat sizes vary from designer to designer, so some hats will fit a smaller or bigger head depending on the style. Thankfully, most of these styles will have an adjustable inner drawstring or band to keep the hat in place and offer flexibility in fit if it runs a little large. 

Men’s Hat Sizes

Men’s hats and caps are generally sized in types: numerical sizing and alpha sizing (small through extra large). In some cases, you may find men’s hats listed as OSFM, or one size fits most. These OSFM hats will generally fit heads with a circumference of 21.5 inches to 23 inches or a medium/large.

When you’re shopping for hats sized in alpha or numerical sizing, the first thing you’ll want to do is carefully measure your head following our measuring guide below. Once you’ve determined the circumference of your head, use our hat size chart to determine which size to order. 

Measuring Your Head

Determine hat size by using a flexible tape measure, or a string and ruler. You may also measure your head by printing out our handy custom measuring tool. Measure from the back of your head bringing the ends together at the center of your forehead right above your eyebrows. Use the hat size chart below to determine your size, rounding to the nearest eighth of an inch as necessary. It is important that you measure your head, even if you’ve found a great fit with a certain size in the past, as hat sizes do vary brand by brand. Remember, fitting your head isn’t an exact science or a guarantee of hat fit. View our convenient hat sizing guide for men and women for more information.
