Face Shape Calculator: Find Your Perfect Hat Match (In 60 Seconds)
Most people think they look “stupid” in hats. They spend $50 on a new cap, get home, look in the mirror, and realize it looks like a disaster.
The result? That poor hat ends up in the closet gathering dust for three years.
Here’s the thing: The problem isn’t your face. It’s that you’re picking hats that fight against your natural features.
If you have a round face and wear a round hat, you look like a ball.
It’s all about balance.
That’s exactly why we built this free face shape calculator. In about 60 seconds, you’ll finally stop guessing. You’ll know exactly what face shape you have and which hats actually make you look good.
Try the tool below and see your perfect match.
Face Shape Calculator
Enter your measurements below to calculate your face shapeHow to Measure Your Face Shape in 4 Easy Steps

Grab a soft measuring tape and follow these four steps:
(You can use either inches or centimeters. Both work perfectly.)
Step 1: Measure Your Forehead Width
Find the widest part of your forehead. This is usually halfway between your eyebrows and your hairline. Measure from one side of your hairline to the other.
Step 2: Measure Your Cheekbone Width
Place the tape across the pointiest part of your cheeks. Start from the bump just below the outer corner of one eye and measure across to the same spot on the other side.
Step 3: Measure Your Jawline
Measure from the tip of your chin to the corner of your jaw (just below your ear). Note this number and multiply it by two. This total is your jawline measurement.
Example: If the distance is 5 inches, your total jawline measurement is 10 inches (or 12 cm becomes 24 cm).
Step 4: Measure Your Face Length
Measure from the very center of your hairline straight down to the tip of your chin.
Once you have these four numbers, enter them into the face dimensions calculator above.
In seconds, you will know exactly what face shape you have and which hats will actually make you look good.
Pro Tip: If you do not have a flexible measuring tape, just use a piece of string. Wrap the string around the area, mark the length, and then lay it flat against a standard ruler to get your number.
What Is My Face Shape? (And Which Hats Actually Fit)
Once you enter your numbers into the face shape calc, you will fall into one of these seven categories.
Here are the 7 basic face shapes and the specific hats you should look for:
1. Oval

An oval face is longer than it is wide. Your jaw is slightly narrower than your forehead, and everything is rounded. Since your proportions are already balanced, you are in luck. Almost any hat looks good on you.
You can pull off baseball caps, fedoras, and beanies without even trying. Because you have so many options, you should experiment with different hat styles to see what fits your look best.
One small warning: just stay away from hats with massive crowns that make your head look unnecessarily long.
2. Round

If your face length and cheekbone width are basically the same, you have a round face. Your jawline is soft and does not have sharp angles. To balance this out, you need a hat that adds structure and angles.
Look for fedoras with a sharp pinch or structured caps with a medium crown worn slightly back. These add definition and make your face look slimmer.
Avoid round beanies, bucket hats, and floppy hats, as they emphasize the roundness of your face.
3. Square

A square face is all about symmetry. Your forehead, cheeks, and jaw are the same width, and your jawline is boxy. The goal is to use rounded hats to soften those sharp corners. Dad hats with curved brims and rounder beanies work best here.
Stay away from flat-brim snapbacks or square crowns unless you want your head to look like a brick.
4. Rectangle (Long)

This is basically a square face that is longer than it is wide. You still have that strong jaw, but your face has a lot of vertical length. You want to avoid adding even more height to your head.
Stick to wide-brim hats, ivy caps, or low-profile baseball hats. If you wear a tall beanie or a high-crown trucker, your face is going to look like it goes on forever.
5. Heart

This shape is widest at the forehead and tapers down to a small, pointed chin. Your jaw is the narrowest part of your face. You want a hat that balances your wide forehead without making your chin look tiny.
Bucket hats and baseball caps with a deep curve are your best bet. Try to avoid giant, wide brims that swallow up the bottom half of your face.
6. Triangle

This is the opposite of a heart shape. Your jaw is the widest part of your face, and your forehead is the narrowest. Since the “weight” is at the bottom, you need a hat that adds volume to the top.
Structured snapbacks and trucker hats work great. Stay away from tight, small beanies that make the top of your head look like it is shrinking.
7. Diamond

This is a rare shape where the cheekbones are the widest part. Your forehead and chin are both narrow. You want to add some width to your forehead to balance those wide cheeks.
Flat caps and fedoras with a medium brim do this perfectly. Just avoid hats with narrow crowns, or your cheekbones will look way too wide.
Can I Use This as a Head Shape Calculator?
Actually, no.
This tool is designed to find your face shape. That way, you can pick a hat style that looks good on you.
But it won’t tell you if a hat will actually fit your head.
For that, you need to use our hat size calculator.
You can enter your measurements in inches or centimeters there. It will give you the exact size number you need to look for when you shop.

Do Men, Women, and Girls Need a Different Face Shape Tool?
We get this question all the time: “Do I need a different calculator if I’m a male or a female?”
The short answer is no.
The math of a face shape doesn’t care about gender. An oval is an oval, and a square is a square.
Whether you are a man looking for a rugged flat cap or a girl trying to find a beach hat, the goal is always the same: balance.
Here is the reality.
Men usually have wider jawlines and more “boxy” features. Girls and women often have softer curves and more prominent cheekbones.
This just means you’ll use your results differently. If you’re a guy with a sharp, boxy jaw, you might pick a rounder hat to soften things up. If you’re a woman with a round face, you’ll probably want a hat with more “edge” to add some definition.
This face measurement calculator just gives you the facts. It works for everyone. Once you know your shape, you can stop guessing and finally buy a hat that actually looks good on you.
Why Use a Calculator Instead of a Face Shape Detector?
Online face shape detector tools are fun, but they aren’t reliable for buying hats.
The big problem is that phone lenses slightly stretch your face. They can make your forehead look wider, or your face look longer than it really is.
A detector is just measuring a distorted picture. Plus, a photo is 2D, but your face is 3D. A camera can’t feel where your jawbone actually curves or find the widest part of your cheekbones.
It is just guessing based on shadows, which change their mind every time you move.
If your room is a little dark or you tilt your head an inch, those tools glitch out. It might tell you that you have a heart-shaped face one second and a square face the next. You cannot spend your money based on a guess.
This tool is different. Instead of a shaky camera filter, you are getting your face shape based on measurements.
When you take a measuring tape to your forehead, cheekbones, and jaw, you get the truth. Numbers don’t lie, and they don’t change just because you have bad lighting.
If you’re going to spend your hard-earned money on a good hat, you need to know for sure what you’re working with. Taking sixty seconds to measure yourself is the only way to stop the guessing game and finally get it right.
What’s your face shape?
Stop guessing. Use this face shape calculator to find your face shape and discover which hats will look great on you.
Now that you know your face shape, you can shop smarter and choose hats that fit your features perfectly.
