A wizard hat is a tall cone with a brim, and you can make one in an afternoon with fabric, a needle, and basic stitching
A wizard hat has two main pieces: a cone that forms the tall crown, and a circular or oval brim that sits around the base. You sew the cone from a wedge of fabric, attach it to the brim, and add a chin strap if you want it to stay on during wear. The whole project takes about two to four hours, depending on whether you hand-sew or use a machine. No pattern is strictly necessary—you can draft one from measurements, or scale up a child's hat pattern if you find one online.
The hat works best in a stiff or semi-stiff fabric. Felt, cotton canvas, or craft interfacing all hold their shape well. Avoid thin cotton or knits, which will droop and lose the pointed silhouette. If you want a dramatic, structured look, use a heavier felt or add interfacing to a lighter fabric.
Key Takeaways
- A wizard hat cone is sewn from a wedge of fabric, and the size of that wedge determines how tall and pointed the finished hat will be.
- The brim is a circle or oval of fabric attached to the base of the cone, and you can make it as wide or narrow as you prefer.
- Hand-sewing works fine for this project, but a sewing machine speeds up the seams and makes them stronger.
- Felt and canvas hold their shape better than thin fabrics, and adding interfacing to lighter materials helps the hat stand up straight.
- A chin strap made from ribbon or fabric strips keeps the hat find on your head during wear or movement.
Measure and draft your cone pattern
Start by deciding how tall you want the hat. A typical wizard hat crown is 10 to 16 inches tall from base to point. Write down your target height, then measure the circumference of the head it will fit—usually 20 to 24 inches for an adult, smaller for a child.
The cone pattern is a wedge (or sector) of a circle. To draft it, you need two measurements: the radius of the full circle the wedge comes from, and the angle of the wedge. A straightforward method is to use a compass or a piece of string pinned at one end. Set the radius to your desired hat height plus 1 inch for seam allowance. Draw an arc. Then measure along that arc until the distance equals your head circumference plus 1 inch for seam allowance. Draw lines from the center point to both ends of the arc. That wedge is your cone pattern.
If math feels uncertain, use an online cone calculator (search "cone pattern calculator") and enter your hat height and base circumference. Print the result or trace it onto paper. Add 1/2 inch on the two straight edges for seam allowance.
Cut and sew the cone
Lay your pattern on the fabric and pin it down. Cut along all edges with sharp scissors or a rotary cutter. You now have a wedge of fabric. Fold it so the two straight edges meet, and pin them together. The fabric will naturally form a cone shape as you bring those edges together.
Sew the seam by hand using a backstitch, or use a sewing machine set to a straight stitch. Start at the point of the cone and sew toward the base. Backstitch at the beginning and end to lock the thread. If you hand-sew, use thread that matches your fabric and make stitches about 1/8 inch apart. If you machine-sew, use a stitch length of 2 to 2.5 millimeters.
Once the seam is sewn, try the cone on your head. It should fit snugly around the base without gaps. If it's too loose, you can take in the seam slightly. If it's too tight, you may need to re-cut a larger wedge.
Make and attach the brim
The brim is a circle or oval of fabric. Measure the circumference of the cone's base opening. For a brim that extends 3 to 4 inches out from the cone, add 6 to 8 inches to that circumference, then divide by 3.14 to get the diameter. For example, if the cone base is 22 inches around, add 7 inches to get 29 inches, then divide by 3.14 to get a diameter of about 9 inches. Draw a circle of that diameter on your fabric and cut it out. Add a second circle of the same size if you want a two-layer brim (this makes it stiffer and more finished-looking).
If you cut two circles, place them right sides together, sew around the edge leaving a 2-inch gap, turn it right-side out through the gap, and hand-stitch the gap closed. Press it flat. If you cut one circle, you can fold the raw edge under 1/2 inch and press it, or leave it raw if you plan to bind it later with bias tape.
Pin the brim to the base of the cone, right sides together. The cone's base opening should sit inside the brim's inner edge. Sew them together using a backstitch or machine stitch, working all the way around. Trim any excess seam allowance and press the seam flat. Turn the hat right-side out if it isn't already.
Add a chin strap for security
A chin strap keeps the hat from sliding off during movement or play. Cut a strip of fabric or ribbon about 1 inch wide and 16 to 20 inches long. Fold it in half lengthwise and sew the long edge closed, or use pre-made ribbon. Attach one end to the inside of the brim on one side of the hat, and the other end to the inside of the brim on the opposite side, using a needle and thread or a sewing machine. Sew over the attachment point several times to make it strong.
Test the strap by tying it under your chin. It should be snug enough to hold the hat in place but not so tight it cuts off circulation. You can adjust the length by moving the attachment points or by tying the strap differently.
Finish the edges and add details
If your fabric frays, you can bind the raw edges with bias tape or a strip of contrasting fabric. Fold the tape over the edge and sew it down by hand or machine. This is optional but gives the hat a more polished look.
Add embellishments if you want: a star or moon appliqué on the front, embroidered symbols, a buckle on the brim, or a feather tucked into the seam. You can also paint or dye the fabric before you sew if you want a specific color or pattern. Let any paint or dye dry completely before cutting and sewing.
Troubleshooting common problems
The cone won't hold its shape. Your fabric is too thin or too soft. Switch to felt, canvas, or add interfacing to a lighter fabric. You can also stiffen the finished cone by spraying it with fabric stiffener (available at craft stores) and letting it dry while shaped over a form.
The seam is lumpy or puckered. You may have pulled the thread too tight while sewing. Loosen your tension slightly if you're using a machine, or sew with a lighter hand if you're hand-sewing. Make sure the fabric edges are aligned as you sew.
The brim is floppy. Cut a second layer of brim and sew them together, or add a layer of interfacing between two layers of fabric. Press the finished brim flat and let it dry in that shape.
The hat is too small or too large. If it's too small, you can stretch it slightly by steaming it gently and shaping it over a form while it dries. If it's too large, you can take in the cone seam by 1/4 to 1/2 inch and re-sew it.
Frequently Asked Questions
Can I make a wizard hat without a sewing machine?
Yes. Hand-sewing works perfectly for this project. Use a backstitch, which is strong and holds seams securely. It takes longer than a machine—expect an extra hour or two—but the result is just as good. Make sure your needle is sharp and your thread is knotted at one end.
What fabric should I use if I don't have felt?
Cotton canvas, denim, or heavy cotton work well. Avoid thin fabrics like muslin or jersey. If you only have a lighter fabric, sew a layer of interfacing to the back before cutting. Craft interfacing (the kind you iron on) is easiest and available at any fabric store.
How do I make the hat taller?
Increase the radius of your cone pattern. If you used a 12-inch radius and want a taller hat, try 14 or 16 inches. Remember to recalculate the wedge angle so the base circumference still fits your head. An online cone calculator makes this quick.
Can I make a wizard hat for a child?
Yes. Measure the child's head circumference and use a shorter height—8 to 12 inches is typical for a child's hat. Follow the same steps, just with smaller measurements. Test the fit before you sew the final seams.
What if I want a wider or narrower brim?
The brim width is up to you. A narrow brim (1 to 2 inches) looks sleek. A wide brim (4 to 6 inches) is more dramatic. Just measure from the cone's base opening outward and cut your circle accordingly. A wider brim needs more fabric and may need extra layers or interfacing to stay stiff.
