Ysolda’s size chart for knitwear designers

Inclusive size charts for sizes xxs to 7xl, created by a knitwear designer and featuring measurements that can be difficult to find. Newly updated with an extended size range with measurements for cup sizing and broad shoulders. 

These charts are a compilation of measurements from many resources, as well as feedback from my customers. They are offered as a free community resource to knit and crochet designers. They were updated in June 2026 to better reflect the updates I've made to the sizing I use in my own patterns.

Two versions of the chart in inches and cm are provided, one with a 2" / 5 cm grade rule (gap) between each size at the chest. The other chart is based on letter sizes xxs to 7xl and reflects the garment industry standard of having slightly smaller absolute gaps between smaller than larger sizes. 

This can be controversial, as it can be less size inclusive when the gaps between larger sizes are very large and force someone who is between sizes into a size that is too large or too small. My goal was to create a size chart that is manageable to follow in a pattern, as size inclusive as possible, and set a grade rule between each size that would, in practice look and feel roughly the same. You are, of course, welcome to use the 2" / 5cm version of the chart as the basis for your own custom size chart.

Currently the majority of the data used to build these charts is based on the measurements of average height - approx 5'4" to 5'7" cis women. You may wish to offer alternative lengths or adjustments for petite and / or tall sizes.

A broad shoulder measurement is included for a few key measurement points, and this in addition to changes to length and data from other resources can be used to build a more gender inclusive size chart for patterns. I'm hoping to offer an update with more options and suggestions on how to include gender inclusive fit options within patterns in the future.

You are more than welcome to use this size chart for your personal knitting if you find them helpful. It is, however, primarily a tool for grading multi-size patterns and might not be very helpful for fitting individual projects. 

The charts include a lot of data and there are very few individual people who perfectly fit a standard size chart. I'd always encourage you to take measurements of your own body or the person you're knitting for and adapt your project if required. All measurements given in these charts are body measurements, not the final measurements of a project. You definitely don't need to measure this many points on the body to get a great fitting project, many of these are provided because they're useful to designers when calculating shaping or placing design details. 

You might find these resources useful for choosing a size and adapting patterns to fit your body.
