Size chart app
Size charts that look like your brand.
Build a size guide for every product in minutes. Paste your table, start from a template or snap a photo, then design it to match your store. Shoppers see your measurements and get a size recommendation in the same place.

Start in seconds
Templates, paste, CSV or a photo
Start from a template for T-shirts, shirts, hoodies, trousers, dresses, skirts or shoes. Or bring the chart you already have: paste it from a spreadsheet, upload a CSV, or take a photo and let AI turn it into a table.
- Nine ready-made templates
- Paste and CSV import with a guided column check
- Photo to size chart with AI (Pro)

Every size system
EU, UK, US and letters, side by side
Add a column for every size system your shoppers use, such as EU, UK and US for shoes or IT and S/M/L for tailoring. Matching works with the size names in your store too, even combined names like “UK 7 | EU 41”.
- As many size columns as you need
- Shoppers answer the size question in any of them
- Centimetres, millimetres and inches, converted for shoppers

Design and content
More than a table
Add headings, formatted text with links, images and how-to-measure guides, extra tables for garment measurements, tabs, collapsible sections and a fit scale. Style the table to match your store and preview every change live.
- Text, images, tabs and collapsible sections
- Fit scale from snug to loose
- Model note, such as “Model is 186 cm and wears M”
