How to Make Cat Ears Out of Paper That Last All Night

6 min read ยท The Costume Rack

To make cat ears out of paper, cut two triangles about 3 to 3.5 inches tall from black cardstock, score a line down the middle of each, fold them slightly so they have a ridge, and add a tab at the base. Glue a smaller pink or grey triangle inside, then hot glue the tabs to a headband or two hair clips. The center fold is what keeps paper ears standing up all night.

If your ears are done but the rest of the black cat is still a question mark, The Costume Rack builds the whole look from your closet: Start my costume.

What you need

Printer paper alone is too floppy. If that is all you have, glue two or three sheets together first.

Getting the ear shape right for adults

Most paper cat ear tutorials are sized for small kids, which is why they look tiny on a teen or adult head. Here are proportions that look right:

Style Height Base width Look
Small and cute 2.5 in 2.5 in Subtle, good for school or work
Classic black cat 3 to 3.5 in 3 in The standard, reads well in photos
Cosplay size 4 in 3.5 in Bold, anime and cosplay looks

Drawing the template

  1. On your cardstock, draw a triangle with the height and base you picked.
  2. Curve the two long sides outward very slightly. Real cat ears are not perfectly straight.
  3. Round the tip just a little so it is not sharp.
  4. Add a rectangular tab, about half an inch tall, along the bottom edge.
  5. Cut it out, trace it for ear number two, and cut again.

For a curved headband, make the tab slightly curved too, so it hugs the band.

Folding so they stand up

This is the step most people skip, and it is why paper ears flop.

The center score fold

  1. Lay the ruler from the tip to the middle of the base.
  2. Press firmly along it with a dry pen to score a line.
  3. Fold the ear very slightly along that line, so it has a gentle ridge like a tent.
  4. Fold the tab backward along the base line.

The ridge gives the paper strength in the same way a folded sheet of paper stands up when a flat one would not.

Extra support for a long night

Adding inner-ear color

  1. Trace your template onto pink, grey or glitter paper.
  2. Cut it about half an inch smaller all round.
  3. Glue it to the front of each ear, lining up the bottom edges.
  4. Score and fold it with the ear so the ridge runs through both layers.

Want a fluffy look? Glue a few strips of cotton wool or faux fur to the inner ear. For an all-black look, skip the inner ear and outline the edge in silver marker.

It is easy to spend an hour on perfect ears and then realise the outfit, tail and makeup are still undecided.

Mounting on a band or clips

On a headband (how to make cat ears headband style)

  1. Put the headband on and mark where your ears should sit: about 2 inches either side of center, angled slightly forward.
  2. Add a line of hot glue to the tab and press it onto the band from behind.
  3. Wrap the join with black tape so it is hidden and stronger.
  4. Let it cool before wearing.

On hair clips

Glue each tab to the top of an alligator clip. Clip into your hair at the angle you want. Clips are great if headbands give you a headache, and they blend with dark hair.

Hair cat ears (no paper at all)

If you want to know how to make cat ears with hair, make two small high buns or twisted triangles on top of your head and pin them. It pairs well with paper ears on a friend in a group costume.

Finishing the cat look

Here is how to dress up as a black cat with things most people own.

Black cat costume women and adults

Cat costume for guys

A black hoodie and black jeans, the paper ears (or ears on the hood), and a simple nose and whiskers. Clean and easy.

No-makeup cat

Ears, all black clothes and a tail. That is enough. A tutu also turns into a cute cat; see Halloween costume with a tutu.

Cats are great in groups too. A witch and her black cat is a classic duo, and three cats in three ear colors is an easy trio (more in Halloween costume ideas for teens trio).

Ears done, costume next

Now you know how to make cat ears out of paper that stand up all night, the rest takes about two minutes. The Costume Rack matches your vibe and closet to the black cat (or another of its sixteen costumes), lists every piece with a "Find it" link, and gives you a no-makeup build.

FAQ

How do you make paper cat ears stand up?

Score a line down the center of each ear and fold it slightly so it has a ridge. Heavy cardstock plus a cardboard strip along the back keeps them upright all night.

How big should cat ears be for adults?

About 3 to 3.5 inches tall with a 3 inch base for a classic black cat. Go 4 inches tall for cosplay, or 2.5 inches for a subtle look.

How do you make cat ears with cardboard?

Use the same template on a cereal box, then paint it black or cover it with black paper. Cardboard ears are sturdier but slightly heavier, so mount them with strong glue.

How do I dress up as a black cat easily?

Wear all black, add cat ears and a tail, and draw on a nose and whiskers. You can skip makeup entirely and still read as a cat.

Can I make cat ears without a headband?

Yes. Glue the ears to alligator clips, or style your hair into two small buns on top of your head as cat ears.

Put your group on one rail so nobody turns up as the same thing, and build each costume piece by piece from your own vibe and what you already own.
