Hat Size & Fit Guide
Sizing Guide
Every Gem Hat uses elastic sweatbands that adapt to your head shape for all-day comfort. We offer sizes from S to XL to accommodate a wide range of head sizes. When you visit our studio, we'll measure your head and help you find your perfect fit.
Round
Soft curves with similar face width and length. Go for hats with taller crowns and angular shapes like our Flat Brim or Western to add definition.
Diamond
Narrow forehead and chin with prominent cheekbones. Try medium-brim styles with pinched crowns like our Western.
Oval
Balanced proportions with gently curved sides. You're in luck! Almost any style works beautifully with an oval face.
Square
Strong jawline with similar widths across forehead, cheeks, and jaw. Curved brims like our Cowboy style help balance angular features beautifully.
Heart
Wider forehead that tapers to a narrower chin. Best suited for medium-brim hats like our Western and Cowboy styles.

01 | Grab Your Tape Measure
Use a flexible tape measure or a piece of string you can measure afterward.
02 | Measure around your head
Wrap the tape at the middle of your forehead and about 1/8" above your ear, where your hat will naturally sit.
03 | Check the size guide
Compare your measurement to our size chart. Between sizes? Go up for a more comfortable fit.
