Introduction: Why Make Your Own Paper Party Hats?

Making classic cone-shaped party hats is a quick and highly customizable craft for birthdays, New Year’s Eve, classroom celebrations, and any diy party at home. A diy birthday party hat feels more personal than store-bought party favors, especially when each guest can decorate their own party hat.

A diy party hat is usually a cone or crown made from paper, with thin elastic string or ribbon used to secure the hats to the head. The choice of party hat design can depend on the theme or color scheme of the party and whether the hats are for children or adults.

Below, you’ll see how to make a party hat from a flat sheet, shape it, secure it, decorate it, and get the party started. If you found this page through a search and decided to craft for a girl, a birthday boy, or your business event, don’t worry-you won’t miss the essentials.

Supplies You Need to Make a Paper Party Hat

Most supplies are basic craft items. You’ll be glad this paper craft party hat project does not require expensive tools.

• Paper: cardstock, colorful tagboard, construction paper, patterned scrapbook paper, wrapping paper, or a free printable template you can print.
• Tools: pencil, ruler, scissors, optional craft knife, hole punch, stapler, low-temp hot glue gun, clear tape, or washi tape. Cutting tools like scissors are needed to create the party hats.
• Strap options: thin elastic, yarn, baker’s twine, ribbon, or gift-bag string to tie under the chin.
• Adhesives: double-sided tape, hot glue, or a standard stapler can be used to assemble the hats.
• Decorations: stickers, markers, glitter, glitter glue, paint, pom-poms, crepe paper, paper medallions, paper straw candles, and other decorations.
• Best paper choice: medium-weight paper like cardstock or sturdy construction paper works best for durability.

How to Make a Cone Out of Paper (Base for a Party Hat)

Every traditional party hat starts as a simple paper cone. To make a party hat, you’ll need colorful tagboard or construction paper, and you should cut a 10-inch diameter circle from the paper for a child-size hat.

• Draw a circle with a pencil. Use 10 in / 25 cm for kids, 11–12 in / 28–30 cm for adults, or 8–9 in / 20–23 cm for toddlers.
• Cut out the circle. After cutting the circle, fold it in half to find the center, then cut a small triangle from the center to one side, allowing you to shape the hat into a cone.
• To form a cone shape from paper, cut a circle and then cut a wedge out of it; folding the remaining edges together will create the cone.
• Overlap the cut edges and pull them tighter for a taller, narrower cone, or loosen the overlap for a wider hat. A larger semicircle cutout creates a wider hat, while a tighter curve results in a taller, narrower cone.
• Test the fit on the head before sealing. Use a bit of tape first, adjust the edge, then secure it.
• To create a paper cone, you can use three different methods to secure the seam: tape, staples, or hot glue, with hot glue being the most durable option.
• To secure the cone shape of the party hat, you can use tape, staples, or hot glue, with hot glue being the most durable option.

You can also easily fold a traditional paper hat using standard rectangular printer paper or newspaper as an alternative to glue or tape. That folded style is less like a cone, but it is super easy for last-minute fun.

How to Make a Party Hat from Your Paper Cone

Now turn the cone into a wearable hat. Use a hole punch to make two small holes on opposite sides near the bottom rim, about 0.4–0.5 in / 1–1.2 cm up from the edge. To make a chin strap, holes can be punched on opposite sides of the bottom rim and elastic or string can be threaded through.

Cut thin elastic or yarn about 18–22 in / 45–55 cm for kids, or longer for adults. Thread it from outside to inside, then tie secure knots inside the cone. If several ages are wearing the same design, add a small bead or cord lock so each person can adjust the fit.

For comfort, trim or gently curve the front edge so it does not press into the forehead or ears. If a child dislikes chin straps, hot glue the cone to a plastic headband or tape it inside a paper crown.

Alternative Style: DIY Crown‑Style Paper Party Hat

Not every happy party hat needs to be pointed. Crown hats are cute, safe for younger kids, and great for classroom celebrations.

• Measure the head with scrap paper or soft tape, then add 0.5 in / 1–1.5 cm for comfort.
• Cut a strip 3–4 in / 7–10 cm tall.
• Draw triangles or rounded peaks along one long edge.
• Cut the peaks with blunt-tip scissors for younger kids.
• Overlap the ends to match the head size, then staple or tape firmly.
• Let kids decorate their own hats with stickers, stars, paper jewels, or “Happy Birthday.”

This crown-style diy party option is especially good when children want to create something fast without handling hot glue.

Decorating Ideas for DIY Birthday Party Hats

Decoration is where diy birthday hats become personal. Match dinosaurs, unicorns, retro colors, Winnie the Pooh, Minnie Mouse, or any birthday party theme with themed scrapbook paper and embellishments; for a full party, you might build on these ideas with the best unicorn party decoration ideas.

Try these ideas for hats, then pair them with creative birthday decorations with balloons at home for a cohesive party look:

• Add names: Decorating party hats can be personalized by adding a friend’s name and their favorite things to make them more special and thoughtful.
• Add a topper: A fluffy pom-pom or rolled tinsel ball can be glued to the top point of the cone for decoration.
• Add dimension: Adding paper medallions to party hats can enhance their appearance, providing dimension and a decorative touch that aligns with the party theme.
• Add texture: layer fringed crepe paper, confetti dots made with a punch, washi stripes, or glitter glue.
• Add a number: make a paper rosette and place the age in the center for an adorable photo picture.
• Add playful extras: paper straw candles work well around a cake-themed topper.

For less mess, decorate the flat template before forming the cone. It is easier to color, paint, glue, and place stickers while the paper is still flat.

Tips for Making DIY Party Hats with Kids

DIY birthday crafts double as activities and souvenirs for kids birthdays, and you can also explore DIY kits for creative projects and fun learning experiences if you want ready-to-go options. Set up a craft station early so kids can wear their creations during cake, games, and photos.

• Pre-cut cones or crown strips before guests arrive.
• Put markers, stickers, pre-measured elastic, ribbon, and small decorations in trays.
• Let school-aged kids cut and staple with supervision.
• Let younger kids color, stick, and choose decorations.
• Adults should handle hot glue guns and very sharp scissors.
• Use table covers, small trash bowls, and damp cloths for cleanup.
• Plan 10–15 minutes of filling, decorating, and fitting time.

If you hope to reuse the own hats later, write names lightly inside the rim and store them upright.

FAQ About Making Paper Party Hats

What kind of paper is best for a DIY birthday party hat?

Medium-weight cardstock around 65–80 lb or 176–216 gsm works best because it holds the cone shape without wrinkling. Construction paper is fine for quick kids’ crafts, while scrapbook paper or gift wrap can be layered over cardstock. Avoid thin printer paper alone for full-size hats because it tears once decorated.

How can I resize a party hat for toddlers vs. adults?

Use a smaller or larger starting circle: 8–9 in / 20–23 cm for toddlers, 10 in / 25 cm for kids, and 11–12 in / 28–30 cm for adults. Lightly tape the seam, try it on the head, then adjust the overlap until snug. Elastic also makes one hat pattern fit more people.

How do I keep party hats from slipping off?

Use thin elastic instead of loose yarn for active kids. Position the strap behind the ears and under the chin, and cover sharp staple ends or bulky knots. For toddlers, attach the cone to a headband with hot glue.

Can I reuse paper party hats after the birthday party?

Yes. Store them upright in a dry box away from moisture and sunlight. Replace stretched elastic if needed. Heavily glittered or food-stained hats are usually better recycled and remade fresh for the next party.

How far in advance can I make DIY party hats?

You can make homemade party hats 1–2 weeks ahead if they stay dry and dust-free. For last-minute parties, prepare circles or a template ahead of time so each hat takes about 15–30 minutes. Make one sample first to check sizing, supplies, and decoration time.
