You can now add a size calculator to Size Chart, so shoppers enter their own measurements and see their recommended size straight from your chart. It's off by default, so nothing changes until you turn it on.

What's new

Turn it on in Size Chart → Settings → Size calculator → Show a size calculator.

Shoppers open the size chart, select What's my size?, enter their measurements and see their size. They can switch between cm and inches.

How it works

The calculator asks for one field per body measurement in your chart, such as chest, waist, hip or inseam. Garment measurements (length, width, half chest) and size-system columns (EU, US, UK) are not asked.

For the calculator to work, your chart needs:

  • A table. Made with Create table (charts made from an image don't work).
  • Sizes in the first column. Smallest first, with at least two sizes.
  • A value in every cell. A number or range, such as 24-24.9, with no merged cells, in cm or inches (not mm).

For example, for shoes, add a column called Foot length (cm) and shoppers get a foot-length field.
