Honestly, most people think a top hat is just for Monopoly men or Victorian chimney sweeps. But when you’re staring down a last-minute costume party or a school play, knowing how to make a paper top hat is basically a superpower. It’s one of those projects that looks incredibly complex from the outside—all those curves and structural integrity—but it’s really just a geometry problem you can solve with some cardstock and a bit of tape.
I’ve spent years messing around with paper engineering. I've made everything from fragile origami cranes to structural cardboard furniture. The top hat? It’s the sweet spot. It's rewarding. It’s also surprisingly easy to mess up if you don’t respect the math behind the circle.
If you try to wing the measurements, you’re going to end up with a hat that either slides down over your eyes or perches awkwardly on top of your head like a tiny, sad pillbox. We aren't doing that today. We’re making something that actually looks like it belongs on a stage or at a steampunk convention.
The Secret Physics of the Brim and the Crown
Before you grab the scissors, you have to understand the three distinct parts. You’ve got the brim (the flat circular part), the crown (the vertical tube), and the tip (the flat circle on top). Most beginners make the mistake of cutting the brim first without thinking about the head size.
Here is the thing.
You need to measure the circumference of the head first. Use a soft measuring tape. If you don't have one, use a piece of string and then lay it against a ruler. Let's say your head is 22 inches. That is your magic number. That 22 inches is the length your crown needs to be, plus an inch for the overlap where you'll glue it together.
Materials You Actually Need (and Why Paper Choice Matters)
Don't use standard printer paper. It’s too flimsy. It’ll wilt the second you put it on. You want poster board or heavy cardstock. If you’re feeling fancy, go for black 12x12 scrapbooking paper, but you’ll likely need to tape two sheets together to get the length for the crown.

- Strong Adhesive: Double-sided tape is the secret weapon here. Hot glue is okay, but it creates bumps.

How to Make a Paper Top Hat Without Losing Your Mind
Start with the crown. This is the "tube" of the hat. Since we know our head measurement is 22 inches (as an example), we’re going to cut a rectangle that is 23 inches long. The height is up to you. A classic Abe Lincoln style is usually about 6 to 8 inches tall.
Here is a trick I learned from professional milliners: break the fibers. Take your rectangle of cardstock and run it over the edge of a table, like you’re curling ribbon. This makes the paper "want" to curve. If you don't do this, your top hat will look like a polygon instead of a cylinder. It’ll have weird creases. We want a smooth, architectural curve.
The Tab Method vs. The Inner Ring
Once you have your tube, you need to attach it to the brim. This is where people usually give up. You have two choices. You can cut "tabs" into the bottom of the tube—little 1-inch slits all the way around—and fold them outward. Or, you can cut the tabs into the inner circle of the brim and fold them upward.
I prefer folding the tabs inward from the brim. It hides the messy bits inside the hat.
- Draw your large circle for the brim on a fresh sheet of poster board.
- Draw a smaller circle inside it that matches your head diameter.
- Don't cut on that line! Draw another circle about an inch inside that one.
- Cut the smallest circle out.
- Cut slits from the center hole out to the "head size" line to create tabs.
- Fold those tabs up.
Now, you just slide your tube over those tabs and tape them to the inside of the crown. It’s solid. It’s clean. It works every time.
Why Most Paper Hats Fall Apart
The "tip" (the top circle) is the final boss. It has to fit perfectly inside the top of the tube. If it’s too small, it falls in. If it’s too big, the hat bulges.

The math is $C = 2\pi r$. But honestly? Just trace the top of the tube you already made onto a piece of paper. Cut it out slightly larger than the trace line, add some tabs, fold them down, and tuck it into the top of the crown.
Glue it from the inside if you can reach, or use a thin bead of craft glue along the top edge.
Dealing with the "Steampunk" Aesthetic
If you're making this for a costume, plain black paper is a bit boring. Get some metallic spray paint. But wait—don't spray it until the hat is assembled. The paint can make the paper brittle, making it harder to fold those tabs we talked about.
Once it's assembled, hit it with a matte black coat, then lightly mist some bronze or copper over the edges. It gives it that heavy, metallic look without the weight of actual metal.
Variations for Different Occasions
Maybe you aren't trying to look like a 19th-century gentleman.
If you're making a Mad Hatter style hat, you need to flare the crown. Instead of a rectangle for the crown, you need a "fan" shape. This requires a bit of bridge-geometry, but essentially, the top edge of your paper needs to be longer than the bottom edge.

For a tiny fascinator hat, follow the same steps but scale everything down to 25%. Instead of a full brim, you can glue the finished mini-hat onto a plastic headband or a hair clip. These are huge for Kentucky Derby parties or tea parties.
Common Pitfalls to Avoid
- Using too much glue: Paper warps when it gets wet. If you're using white school glue, use a toothpick to spread it thin.
- Forgetting the "Ease": If your head is exactly 22 inches, don't make the hat exactly 22 inches. Add about 1/8th of an inch of "ease" so it actually fits over your hair.
- Neglecting the Grain: Paper has a grain, just like wood. It bends easier in one direction than the other. Test your paper before you cut the long rectangle for the crown.
Taking Your Paper Crafting Further
Once you've mastered the basic structure, you can start experimenting with textures. I've seen people cover their paper top hats in fabric or even old book pages.
If you use book pages, use a decoupage medium like Mod Podge. It seals the paper and makes the hat almost as hard as plastic. It’s a great way to make a costume piece that lasts more than one night.
Your Assembly Checklist
- Measure twice. Seriously.
- Pre-curl the paper to avoid creases.
- Use the tab method for a structural bond.
- Seal the edges with a marker that matches your paper color to hide the white core of the cardstock.
The beauty of learning how to make a paper top hat is that it’s a foundational skill. These same principles of tabs, circumferences, and structural integrity apply to almost any paper sculpture.
Stop worrying about it being "perfect." The slight imperfections are what give it character. Most people won't even realize it's made of paper once you've got it on and you're rocking it with confidence.
Next Steps for Your Project
Start by selecting your material weight. If you're using standard 65lb cardstock, consider doubling up the brim by gluing two sheets together for extra stiffness. Once your base is built, use a hot glue gun only for external decorations like ribbons, clockwork gears, or feathers, as the heat can sometimes warp the main structure if used on the primary seams. Finally, if the hat feels a bit loose, glue a small strip of foam weather stripping or a folded paper towel inside the inner rim to create a custom, snug fit.
