If you want to know how to measure your head for a fitted hat, here is the whole answer in one breath: wrap a soft tape around the widest part of your skull, about a half-inch above your ears and eyebrows, keep it snug but not strangling, do it three times, and match the inches to a 59FIFTY size chart. That is the take. Everything else is the why, the chart, and the small mistakes that put you in the wrong crown. A fitted hat has no adjustable strap and no snap, so the number is the whole game.
The fastest accurate way to measure your head for a fitted hat
Use a flexible cloth tape, the kind a tailor uses. Not a metal carpenter’s tape, that thing fights your skull and lies to you.
No cloth tape in the house? Wrap a piece of string or a phone charging cable around your head, mark where it overlaps, then lay it flat against a ruler.
- Stand in front of a mirror so you can see the tape sitting level all the way around.
- Set the tape across your forehead about a half-inch above your eyebrows.
- Run it around to the widest bump at the back of your head and just above the tops of your ears.
- Pull it snug, the way a hat actually sits, then add nothing. A finger of slack is too much.
- Read the number, then do the whole thing two more times and take the largest honest reading.
Why three times? A quarter-inch error bumps you a full hat size. The increments on a 59FIFTY are only an eighth of an inch apart, so sloppy tape work is the difference between a hat that hugs and a hat that floats.
Measure your bare head. If you wear a durag or wave cap under your fitteds, measure with it on, because that fabric eats real estate and changes your number.
Fitted hat size chart: head inches to hat size
Once you have your circumference, this is the New Era 59FIFTY conversion. Fitteds run from 6 7/8 up to 8 1/4 in eighth-of-an-inch steps. Find your inches, read across.
| Hat Size | Head (inches) | Head (cm) |
|---|---|---|
| 6 7/8 | 21 5/8 | 54.9 |
| 7 | 22 | 55.8 |
| 7 1/8 | 22 3/8 | 56.8 |
| 7 1/4 | 22 3/4 | 57.7 |
| 7 3/8 | 23 1/8 | 58.7 |
| 7 1/2 | 23 1/2 | 59.6 |
| 7 5/8 | 23 7/8 | 60.6 |
| 7 3/4 | 24 1/4 | 61.5 |
| 7 7/8 | 24 5/8 | 62.5 |
| 8 | 25 | 63.5 |
| 8 1/8 | 25 3/8 | 64.5 |
| 8 1/4 | 25 3/4 | 65.4 |
If your number lands dead between two sizes, size up. You can shrink a structured wool crown or settle it in over a week, but you cannot stretch fabric back over bone that does not fit.

Bottom line: Soft tape, half-inch above the brows, snug not loose, measured three times. Between sizes, always go bigger.
Why a fitted measures differently than a snapback
A snapback forgives you. The plastic strap covers a two-size range, so a lazy guess still clamps to your head. A fitted gives you nothing back.
The crown is sewn to a fixed circumference and the sweatband is stitched in solid, no drawstring, no elastic. That is the entire appeal and the entire risk.
Crown height matters too. A 59FIFTY runs a tall, structured crown that sits high off the dome, which is the on-field silhouette MLB players wear. A low-profile fitted shaves that height down and can feel tighter at the same tagged size, so the number on the tape is your floor, not your finish. If you are still learning the parts you are measuring around, read our anatomy of a fitted hat breakdown so the sweatband, crown, and button all make sense.
Mistakes that ruin your measurement
Most “my fitted does not fit” stories trace back to one of these.
- Measuring over hair you do not normally have. A fresh wash-and-go or a thick puff adds volume that flattens under a real cap. Measure how you actually walk around.
- Using a stiff metal tape. It will not lie flat on a curved skull and it reads short. Cloth or string only.
- Pulling the tape tight to feel secure. Tight tape gives you a too-small hat that gives you a headache by noon.
- Measuring too high or too low. Up on the crown or down at the hairline both miss the widest point. Half-inch above the brows, every time.
- Trusting one reading. One pass is a guess. Three passes is a measurement.
One more thing the brands will not put on the tag: wool and wool-blend fitteds shrink a hair after a few wears and any contact with moisture, so a wool cap that feels perfect on day one can feel snug by week three. Cotton and the polyester on-field builds hold their size far better. If you already bought a touch tight, our guide on how to break in a fitted hat buys you back some room without a heat gun.
Frequently Asked Questions
How do I measure my head for a fitted hat without a tape measure?
Wrap a piece of string, a shoelace, or a phone cable around your head a half-inch above your eyebrows and ears, mark where it overlaps, then lay it flat against a ruler. Read the inches and match them to a 59FIFTY size chart. Measure three times for accuracy.
What size fitted hat am I if my head is 22 inches?
A 22-inch head circumference is a size 7 in a New Era 59FIFTY. Each eighth-inch up the chart moves you one size: 22 3/8 inches is a 7 1/8, and 22 3/4 inches is a 7 1/4. If you land between two, size up.
Should a fitted hat be tight or loose?
Snug, not tight. A fitted should sit secure with no red mark on your forehead and no headache after an hour. If it slides when you look down it is too big, and if it pinches at the temples it is too small. Aim for firm and comfortable.
Do fitted hats stretch over time?
A little. Wool and wool-blend crowns relax slightly with wear, so a brand-new fitted often feels tighter than it will in a month. Do not size up hoping for major stretch, the gain is small. Cotton and on-field synthetic builds barely move at all.
Why is my measurement between two hat sizes?
Because heads do not land neatly on eighth-inch marks. When you are between sizes, choose the larger one. A slightly roomy fitted can be settled in or shrunk down, but a too-small crown has no give and only gets more uncomfortable as the day goes.
Get the number right and the rest is the fun part: picking the team, the crown, the undervisor. Run your fresh measurement against the full MLB fitted hats hub and grab the cap that actually belongs on your dome.
