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

This circle skirt pattern 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.

After calculating the circle skirt dimensions, you can download the results as a PDF document.

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 of individual circle skirts

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. The circle skirt calculator also calculates fabric consumption for the selected circle skirt type and desired skirt length.

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. How to make a circle skirt pattern in a life size? 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. This will be the centre FRONT/BACK of the circle skirt pattern, label it. 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. 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).

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. Redraw the waist and hem with a shaprie (see the image below).

5. Using a long ruler and a Sharpie, draw the side seam and Centre FRONT/BACK line. Both of these will start at the waist and end at the hem of the skirt pattern.(see the image below).

How to draft a circle skirt waistband?

Elastic waistband casing

The elastic waistband casing is a great choice for every sewing beginner and a super time saver for everyone as you do not have to sew a zipper into the skirt as with the fixed waistband. Use a standard jersey or rib jersey fabric to create one. The easiest way to apply an elastic waistband is with a circle skirt made of knit fabric.

You can also insert an elastic band into the casing so that the skirt will hold better at the waist. The knit fabric of the casing may lose its elasticity with wear and tear. So, the elastic band inside will prevent the skirt waist from slipping down. I like to make the elastic a little more tight so I subtract about 2 – 5 cm (1 – 2”) from the waist circumference.

Instead of a casing, you can go for a nice, decorative elastic band directly sewn to the circle skirt.

Fixed straight waistband

With a fixed waistband you will get a nice snug fit at the waist (see the image below). However, keep in mind that you have to sew a zipper on the skirt, so that you can put it on :). Use one that is about 25 cm (10”) long. You can choose between a concealed zipper (invisible zipper) and an exposed zipper.

If you are concerned the zipper might open, sew a hook and eye just above it. In this case, the upper edge of the zipper will be not aligned with the upper edge of the waistband.


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!!

  3. Hi I just need you to know that I am very tired right now but this calculator is the only good one I’ve found AND you calculate double circle skirts?? I’m so happy I could kiss you, thank you so much I’m so bad at maths and this saved me a lot of headaches

  4. hi im new to sewing and ive never done something without a pattern, what kind of waistband is this skirt for? elastic or something like a zipper? i prefer to do elastic waistbands and im not sure how it would work for this, do i need to add extra in the waist if i plan on doing elastic?

    1. Hi Sarah, thank you very much for such a great question!

      With a circle skirt (quarter, half, full, etc.) it depends on the fabric you are going to use for your skirt:

      1. Woven fabric without added elastic fibres:
      – currently (with woven fabrics), the pattern is calculated for a standard straight waistband and a zipper. Without the zipper, you probably won’t be able to put the skirt on. Your hips might just prevent you from doing so as they are larger than your waist.
      – if you still want to use an elastic waistband as you mention in your comment, I would recommend adding 1 – 2 inches (2 – 5 cm) to the calculated radius at the waist and also at the hem of the skirt. The measurement added to the waist radius together with the stretch of the bias cut fabric of the skirt should give you the needed room for your hips. The added measurement at the hem radius keeps the desired skirt length.

      2. Knit fabric
      – knit fabrics have a lot of stretch
      – you should be able to use an elastic waistband without any adjustments to the calculated pattern measurements

      3. Stretchy woven fabric with elastic fibre:
      – this is a tricky one as some fabrics can have a lot of elastic fibre, some just a little
      – if you can stretch the fabric a lot, you can go with the calculated waist and hem radius without adjustments (as with the knit fabric)
      – if you can stretch it only a little, I would recommend adding the extra 1 – 2 inch (2 – 5 cm) to the calculated radius at the waist and the hem (as with woven fabric without elastic fibre).

      I hope I have answered your question clearly :).
