Start the reading
In WordPress, open WooCommerce → seeonwall.com, then the Products tab. Click Read sizes from product text at the top of the page. The window shows how many products have no Print sizes list and no variations named by size. Click Read sizes from product text.
Only products with no Print sizes list and no variations named by size are read. To read the products sized by their variations too, select the option for them in the window. A product that has a list is not changed.
Check the sizes it found
The list shows each size it found, with the text it comes from. A size whose text states no unit is marked Unit not stated and is not selected: choose cm or in beside it, then select it. Clear the sizes that you do not want.
The size can be wrong when the text gives several sizes, for example the frame or the package. Check the quoted text.
Add the sizes
Click Add … sizes. The sizes go into the Print sizes list of each product, with their unit.
