Online Circle Skirt Pattern Calculator Home » Online Circle Skirt Pattern Calculator

This circle skirt calculator will make pattern drafting much easier for you. There are many different kinds of circle skirts (also referred to as circular skirts), however, they have one in common; you can easily draft them yourself. For each type of circle skirt, there is a different formula based on which a specific pattern is created. To make drafting simple for you, I have prepared this user-friendly online circle skirt calculator that does the math for you.

This page contains an easy-to-use circular skirt pattern calculator you can use to compute dimensions for different circle skirt types based on your body measurements.

If you wish to learn more about the math and construction behind the circle skirts, please read this blog post.

Where is the circle skirt pattern?

To sew a circle skirt, you do not need to buy a specific pattern. You can draw a pattern of any circle skirt type completely yourself based on your body measurements. This way the skirt will fit perfectly. To get all the information you need to draw the pattern, please use the pattern calculator below.

Skirt fullness

The quarter circle skirt has the smallest fullness and has almost no flounce as is made of a small portion of the circle. On the other hand, a double circle skirt is constructed by sewing two full circles together, thus having the largest fullness and prominent flounces. In the images you can see some knee-length circle skirts. On the very left a quarter circle skirt and on the very right a double circle skirt.

Various types of knee-length circular skirts.

Skirt length

You can decide to make the circle skirt any length you prefer. From a mini skirt, through knee length, to a full length. The skirt length together with the type of circular skirt affects fabric consumption. The longer and fuller skirt you decide to use, the more fabric you will need to sew the skirt.

Use of seam and hem allowances

Please keep in mind, that the calculated results do NOT include side seam allowances, waist seam allowances, or hem allowances. This way you can easily change your mind when it comes to seam allowances. You just add them before cutting the pattern pieces out of fabric and can adjust them at the last minute.

There is one exception; the only case where the side seam allowances are included in the circle skirt calculator is the double circle skirt. However, do not forget to add the seam allowances at the waist and hem.

To hem a circle skirt of any type, you can use a bias binding tape (use ready bias binding tapes or make your own using a bias tape maker). As decoration, you can add gathers or flounces to the hem.

How to draft the circle skirt pattern

In the images below you can see simple simple instructions how to draw the life-size pattern. If you need more detailed description of drafting circle skirt patterns, please follow this post.

Keep in mind, that you are going to draw one half of the FRONT/BACK pattern piece. Make sure that you: transfer the pattern twice. Place the pattern on fabric fold.

1. First, draw a long line near the bottom of a large paper and mark a point C on its left side. You will use it to draw the waist and the hem of the skirt (see the image below).

2. Label the line as Centre FRONT/BACK. From point C measure two distances: Radius at waist and Radius at hem based on the results from the circle skirt pattern calculator (see the image below).

Drawing the corresponding angle a specific circle skirt.

3. Using a protractor or this template, draw a long line under the corresponding angle for the selected circle skirt. This line will be its side side seam.

4. Using a pair of compasses or string and pencil, draw the skirt waist and hem (see the image below).

5. The pattern is ready (see the image below).

As you can see, drafting a circle skirt pattern is quite easy even for a sewing beginner. Just use cotton or linen fabric and make a comfortable summer skirt and add a nice DIY garment to your wardrobe. Also, don’t forget about proper equipment that will make your sewing easier.

  1. I just found your site. I love it. So helpful. You’ve done the hard part that keeps me from having to figure the angles and radius out for circle skirts and pleats, etc.

    1. Hi, thank you for your comment. I could do a triple skirt calculator. However, I didn’t make one, because the more full circles you use to construct the skirt, the more fabric is getting lost/hidden between the flounces that stand out from the skirt.
      Also, the fabric consumption for it is quite huge. This applies mainly to full-length skirts.

      I can’t tell, what are your design intentions. For now, you might check out the gathered circle skirt. It might be what you are looking for.

  2. The only calculator to use for circle skirts. Everything else out there is so damn confusing!!! Rockstar. Simple, easy, concise. Love it. Thank you so so much!!
