How to Measure Your Head for the Perfect Hat Fit
Getting the right fit starts with one simple measurement. All you need is a flexible measuring tape, or a piece of string and a ruler.
What You'll Need
- A soft measuring tape, or
- A thin piece of string + a ruler
Step 1 – Measure Your Head Circumference
Wrap the tape around your head about 1 inch (2.5 cm) above your ears, across your forehead and around the fullest part of the back of your head. Keep it snug but not tight; you should be able to slip one finger underneath.
Step 2 – Note Your Measurement
Write down your measurement in inches and centimeters. If using string, mark the overlap point and measure the length against a ruler.
Step 3 – Find Your Size
| Size | Head Circumference (in) | Head Circumference (cm) |
|---|---|---|
| Small | 21⅛" – 21⅞" | 53.7 – 55.6 cm |
| Medium | 21⅞" – 22½" | 55.6 – 57.2 cm |
| Large | 22½" – 23¼" | 57.2 – 59.1 cm |
| X-Large | 23¼" – 24" | 59.1 – 61.0 cm |
Between sizes? Size up. A hat that's slightly loose can be adjusted with a hat size reducer strip (foam or leather tape inside the sweatband). A hat that's too small cannot be stretched without risking damage.
How Brims & Bolos Maps Your Measurement to a Custom Hat
When you place a custom hat order, we use your head circumference measurement to shape and block your hat to your size. Because each hat is handcrafted, minor variation (±⅛") is normal and expected.
Please note: hat sizing can vary slightly by style, brim shape, and material (felt vs. straw). Your measurement is our starting point, not a universal fit guarantee; final fit may vary based on the hat's construction.
Tips for a Better Fit
- Measure at the end of the day when your head is at its largest.
- Measure 2–3 times and use the average.
- If your head is between sizes, size up and use a hat size reducer for a snug fit.
- Hats naturally break in over time and may loosen slightly with wear.
