How to Choose Your Sewing Pattern Size

Sewing pattern sizes are not shop sizes. A pattern size follows body measurements, so the first rule is simple: forget the size on your clothing labels and trust the chart. Here is how to pick the right size every time.

In short

  1. Take your measurements
  2. Find the key measurement
  3. Read the body chart
  4. Check the finished garment
  5. Check the length

1Take your measurements

You need at least your bust, waist and hips. If you haven’t done it yet, follow our guide on how to take your body measurements.

2Find the key measurement

Every pattern page tells you which measurement to follow. As a rule:

Tops, dresses, jackets, coats

Choose by bust. Shoulders and armholes are the hardest to alter, and they follow the bust.

Pants, shorts, skirts

Choose by hips, then check the waist.

Elastic or pull-on waists

Choose by hips, and check the finished waist can stretch over them.

3Read the body measurements chart

Find your key measurement in the body measurements table on the pattern page, and read the size at the top of that column.

Example with a bust of 95 cm on one of our women’s patterns.

Our women’s patterns also give letter sizes:

00 / 0 = XXS2 / 4 = XS6 / 8 = S10 / 12 = M14 = L16 = XL18 = XXL20 = 3XL22 = 4XL

4Check the finished garment measurements

The finished garment measurements are the size of the sewn piece itself. The difference between your body and the garment is called ease.

bodygarment Ease = garment − bodyFitted coat or dress: a little easeRelaxed tee: more easeOversized sweatshirt: lots of ease
Lay a similar garment you love flat, measure it and compare it with the chart.
Half or full? Some of our charts give half-widths measured on the flat pattern (one front or back piece). Double them to get the full circumference.

5Between two sizes?

Loose or oversized styles

Go with the smaller size: the design already has plenty of room.

Fitted styles and wovens

Go with the larger size: it’s easier to take in than to let out.

Different sizes for bust, waist and hips

Totally normal! Blend between sizes (see below).

Draw a smooth line from one size to the next at the side seam: here size 10 at the bust, 12 at the waist and 14 at the hips.

6Check the length

Our women’s patterns are drafted for a height of 1.68 m (5′6″). If you are shorter or taller, compare the finished length and sleeve length with your own clothes and adjust at the hem before cutting.

Sewing something fitted? Make a quick test version (a toile) in cheap fabric first. It takes an hour and can save your good fabric.
