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.

My son was well pleased with the hat
For those of us with planetary-sized noggins, finding good hats is a real challenge. Fortunately this hat was available in XXL and I was finally able to get a bowler that fit me properly. The hat itself is hard felt and not a crushable travel hat, but instead a proper bowler/derby that requires some care. The blocking was excellent and I like the turned up sides that give it a bit more of an “Old West” rather than “British lord” feel. I ordered the blue and found it really suited me. It’s a bit darker than the website photos made it seem, but that was good as far as I was confirmed. It’s definitely not a summer hat given the wool felt and the sturdy construction. Fit and finish are excellent, with nicely bound edges and good quality lining. The internal band could perhaps be improved with a higher grade of leather, but that's a minor nit since nobody sees that except the wearer. Overall, I'm very happy to have finally found a bowler that actually fits me.
Hi Arle, the bowler looks great on you. We are so happy you've found a hat that fits your head & personality. You'll also be happy to hear we just restocked the bowler in several colors!
The hat appears to be of decent quality, however, they do run large. I’ll make it work though.
Purchased for a male customer who had been looking endlessly for a derby. He was pleasantly surprised when he received the hat!
