Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureA size chart needs to do two things: open in a popup on the product page, and switch units. GloSize is built around those two. You set the units on the column itself, in the grid where you type the values: centimeters to inches, kilograms to pounds, or the reverse. Weight works the same way length does. Build the table once, assign it to products or a whole collection, and update it in one place.
ZG Size Guide & Fit Finder helps merchants create clear size charts, fit guides, and size recommendations for product pages. Use built-in templates, import CSV/Excel files, assign charts by product, tag, collection, vendor, category, gender, or region, and show multiple guides as tabs. Shoppers can compare measurements, switch CM/IN units, use shoe size conversion, and get a recommended size through the fit finder.
- Switch units column by column: centimeters, inches, kilograms and pounds
- Show several size tables in one popup, such as tops and bottoms together
- Add a measurement guide image and a note under any chart
- Start from templates for tops, bottoms, outerwear and shoes, or from scratch
- Create size charts from templates for common apparel types
- Recommend sizes using shopper measurements and fit preference
- Show shoe size equivalents for US, UK, EU, Japan, and store sizing
- Show multiple fit or length guides as tabs on one product page
