What is a basic skirt pattern

The basic skirt pattern, also called a skirt block, is a foundational sewing pattern. You can use it to make a simple skirt or combine it with a bodice to create a dress. By adjusting the darts or adding pleats, folds, flounces, or gathers, you can create a variety of shapes and fashion designs.

Tools and measurements you will need

Tools: large sheet of paper, pencil, pen or Sharpie, long ruler, French/flexible curve.

Measurements: waist circumference, hip circumference, waist-to-hip length, skirt length. Use a tape measure and elastic bands. More tips on taking measurements in FAQs.

How to draft the basic skirt pattern step-by-step

If you use the interactive tutorial, it will automatically determine how many front and back darts you need for your basic skirt pattern.

1. First, draw a large rectangle. The bottom of the rectangle represents the hem of the skirt pattern, while the top represents the waist. The height of the rectangle corresponds to the skirt length (see the image below).

b

a = skirt length

b = (hip circumference + ease at hip) / 2

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

hip circumference =

ease at hip =


2. On the left vertical line, mark the waist-to-hip length measurement. On the hem line, mark the side seams. You may notice that the BACK pattern piece has slightly more width than the FRONT. This is intentional: the body requires a bit more fabric at the back to comfortably accommodate the shape of the seat, while the front needs less. The exact measurements for the FRONT and BACK can be calculated using the formula below.

c = waist to hip length

d = (hip circumference + ease at hip) / 2 × 0.48

e = (hip circumference + ease at hip) / 2 × 0.52

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

hip circumference =

ease at hip =


3. From the side seams marking, draw a vertical line up to the waistline. From the hip line marking, draw a horizontal line across the large rectangle (see the image below). This grid will be the area within which you will draw the basic skirt pattern.

4. Label the pattern: the left side will be the FRONT pattern piece, and the right side will be the BACK pattern piece (see the image below).

5. On the centre BACK, mark a waist drop: 3/8” (1 cm) to make the waist at the BACK fit nicely (see the image below). This small drop helps prevent gaping by allowing the waistline to follow the natural curve of the lower back. It ensures a snug, comfortable fit and helps the skirt sit smoothly without pulling away or creating unwanted gaps.

f = waist drop = 3/8”  (1 cm)


6. Now, focus on the waist. On both the FRONT and BACK, mark a preliminary position of the side seams. (see the image below). The measurement for the FRONT includes the FRONT dart width. The measurement for the BACK includes the BACK dart width.

Marking the preliminary side seams on the basic skirt waist.

g = (waist circumference + ease at waist) / 4 + FRONT dart width

h = (waist circumference + ease at waist) / 4 + BACK dart width

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

FRONT dart width = ((hip circumference + ease at hip) – (waist circumference + ease at waist)) × 0.2 / 2

⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯

BACK dart width = ((hip circumference + ease at hip) – (waist circumference + ease at waist)) × 0.4 / 2


7. Locate and mark the BACK and FRONT dart base centres (see the image below). To find their position on the waist, use the formulas below.

Locating and marking the dart centre on the basic skirt BACK pattern piece.
j
i

i = FRONT waist width / 2

j = BACK waist width / 2


8. Draw the dart bases, making sure that the previously marked centres lie exactly in the middle of the corresponding dart base. (see the image below).

l

k = FRONT dart width

l = BACK dart width


9. Starting at the dart base centres, draw the dart fold lines. The end of the dart fold line indicates the end of the dart (the dart point) (see the image below).

m = FRONT dart length = 4” (10 cm)

n =  BACK dart length = 5” (13 cm)


10. From each dart base, draw the dart legs towards the dart point. Make sure both dart legs pass the dart base you have drawn on the straight waist line (see the image below).(see the image below).

11. To accommodate the hips and create a neat waistline, lift the side seams slightly on both the front and back pattern pieces. Raise them by 1/2” (1.2 cm) (see the image below).

12. Take your French curve and draw the waist at the FRONT and BACK. These waist curves are preliminary. You will adjust it later on as you draw the dart.(see the image below).

13. After you have draw the waist, the legs of the darts are not equal in length. Measure both dart legs from the dart points to the point, where they cross the curved waist. Make the shorter one the same length as the longer one – true the dart legs (see the image below).

14. Using the French curve, draw the following: the curved part of the hips, curved parts of the waist line.

15. Using a long ruler, draw the rest of the pattern: centre FRONT, centre BACK, hem and side seams. Mark the grainlines. Your pattern is complete (see the image below).

Working with the basic skirt sloper

If you are just beginning to make your own dress patterns, you might find the following publication by Adele P. Margolis useful. It will teach you how to alternate basic blocks (like the basic skirt sloper in this tutorial to make a different skirt type) to make your own designs.

Now that you’ve drafted your custom skirt pattern in minutes with no math, you can also learn how to draft a clean, well-fitting waistband to complete your skirt. Moreover, unleash your creativity by transforming it into A-line, pencil, or pleated designs with our step-by-step guides—start designing stunning, personalised outfits today.

Basic skirt block drafting FAQs

Yes, it’s perfect for beginners. The skirt is one of the simplest blocks to draft from scratch, and the free tutorial walks you through each step with clear explanations. You don’t need any prior pattern-drafting experience to complete it confidently.
The basic skirt block requires a standard woven fabric. Ideally plain weave, such as cotton or a cotton blend, works best for beginners due to its stability and ease of handling. Avoid stretchy or slippery fabrics like knits or satin until you’re confident with your pattern.
Fabric needs vary with size and skirt length, but 1.5 to 2 yards of 45″ wide fabric is typically enough for a knee-length version. The $4.99 PDF tutorial includes exact yardage calculations and a personalised cutting layout.
To take accurate measurements for your basic skirt block, prepare:
  • Tape measure, two elastic bands, pen, paper (optional, to note your measurements).

Steps to measure:
  • Place one elastic around your natural waist (the narrowest part of your torso).
  • Place the second elastic around the widest part of your hips — this ensures the skirt allows for comfortable movement.
  • Measure your waist circumference at the elastic.
  • Measure your hip circumference at the second elastic.
  • Measure the vertical distance between the two elastics (waist to hip length).
  • Measure your desired skirt length from the waist down (knee length is recommended).
Add a comfortable amount of ease at the natural waist so that any patterns you derive from this block will have the preferred fit at the waist. When testing the basic block, use elastic to keep the skirt in place while checking the fit. Avoid zero ease at the hips, as this would restrict movement.
To draw the pattern itself, please prepare all these tools:
  • large sheet of paper or tissue paper
  • pencil (for drawing guidelines — shown in grey in the tutorial)
  • Sharpie, pen, or liner (for tracing final pattern lines — shown in black)
  • long ruler
  • French curve ruler or flexible curve ruler (for curved pattern lines)
Yes, stretch wovens can work well with this pattern. The added give allows for a closer fit and less hip ease, while still using the same drafting method.
No, this pattern is not suitable for knit fabrics. Knits stretch more and need a different drafting approach with negative ease.

  1. Thank you, I remembered wrong! I reread it and it’s just as you say. Thank you for taking the time to help!

  2. Thank you so much! I’m really excited (and nervous) to try this. Just to clarify, when you said, “you can use 0 ease (or more) for the hips,” I assume you mean 0 or negative ease, as the original tutorial uses 0 ease at the hips. For a woven fabric, it sounds like the zero ease at the hips is what helps the skirt stay in place. For knit fabrics, does that job change to the waist? I ask because it sounds like that is where you recommend reducing ease the most.

    1. Hi Nicole,

      the default eases in the tutorial are the following: WAIST – 0 cm to keep the skirt in place, HIPS – 5 cm to be able to move and sit down.
      For the knit fabric: WAIST – 0 cm ease (or slightly less), without the darts – this will make a snug fit at the waist.
      HIPS – you can try 0 cm or more (meaning 1 cm, 2 cm, 3 cm…) for the hips. In this area, I probably wouldn’t go for a negative ease… However, the amount of ease you want to add (or remove) depends on the fabric and the look you want to achieve.
      I hope I have answered your questions :).

  3. Hi Nicole,

    good question, thank you! Knit fabrics stretch and conform to the body, so you need less ease compared to woven fabrics.

    Reduce the amount of ease: You may use 0 ease for the waist or even negative ease. Negative ease means that the skirt’s waist would have a slightly smaller circumference than your waist. Also, you can use 0 ease (or more) for the hips. All of this depends on the look you want to achieve.

    Adjust the side seams: Take in the side seams to accommodate the reduced ease. You can do this by redrawing the side seam lines.

    Waistband: Instead of a fixed waist with a zipper, you can use an elastic band or elastic casing.

    If you have any further questions, please feel free to contact me again 🙂

  4. Thank you so much for this and the bodice block! It came out perfectly the first time, and I finally have a set of slopers that take into account things like the odd way my shoulders hang! On a different note, I have had the book by Adele Margolis for a couple of years, and use it all the time. It’s been nice for modifying commercial patterns, but it’ll be even better now that I have a custom block! Thank you so much!

  5. Hi, and thank you so much for all of your hard work in putting together these tutorials!
    For the skirt, what kind of waist band would you recommend?

    1. Hi, thank you very much for your comment.
      Draft a standard (not elastic) waistband – either a straight or a curved one.
      A striaght one is easier to explain in text. It is actually a long rectangle that accomodates the skirt waist circumference + overlap for the button. (The darts at the waist are not part of the circumference). The width of the waistband depends on your personal preference.
      Btw: thank you very much for your excellent question. I will include drafring waistbands into the tutorial :)!

  6. I can’t thank you enough for your hard work and providing to all of us these wonderful information. You made the sewing tutorials much easier. Thanks a million

  7. Amazing. Thank you very much. Would you do it also for a basic bodice block? That would really be awesome!!

    1. Hi, I’m happy to read your comment :). I’m definitely planning to make a calculator (dimensions, fabric consumption, etc.) for the basic bodice block and sleeve too. However, it will take me some time as I have finished some of the features on this page (like downloading calculated results as PDF documents) only recently.

    2. Hi Fanny,

      I have done some work and made the basic bodice block drafting tutorial. It also includes a calculator for individual parts of the basic bodice pattern (all downloadable as pdf document).
      I will have to make some minor adjustments (clarifying how to connect the bodice and skirt). However it is a solid base you can use to draft the pattern and make your own designs.

  8. I have to day thank you sooo much for sharing this wealth of information. I used your circle skirt calculator and it was very easy. I love and appreciate your attention to detail. Take care!!!!
