How do sizes and measurements copy between marketplaces?

Short answer

Marketplaces use different size fields, so sizes need a check after a copy. Crosslisty reads sizes such as W32 L34 and 34x30 and adds a Brand, Size and Condition line to the description. Always add measurements in the description.

The shortcut: Crosslisty is a Chrome extension that copies a listing to your other marketplaces, fills each form for you and removes sold items from the rest. Free for 5 fills a day.
