OctoResellHow do sizes and measurements copy between marketplaces?
Marketplaces use different size fields, so sizes need a check after a copy. OctoResell reads sizes such as W32 L34 and 34x30 and adds a details line, such as Brand, Size and Condition, to the end of the description. Always add measurements in the description.

Why sizes go wrong
- Each marketplace has its own size field and values.
- Jeans, shoes and kids’ sizes use different systems.
- Brands run large or small, so a label size is not enough.
