Coming soonSize charts, that fit every product.
Size charts that open right from the product page, switch between cm and inches, and tell shoppers which size fits. Set them up once with rules; they stay in your store.

Measurements stay on the shopper's device.
Live in three steps.
- 01
Make a chart
Start from a template, paste from a spreadsheet, upload a CSV or read it from a photo or PDF of your current chart.
- 02
Choose the products
Rules by tag, vendor, product type or collection, with all or any conditions. Or pick a chart on the product itself.
- 03
Add the block
Add the Size chart block to your product page in the theme editor. Every matching product shows its chart.
See it in one minute.
Everything it does, nothing it doesn't.
Charts by rule
One rule can cover a whole collection or vendor. Combine tag, vendor, type and collection with all or any conditions.
cm and inches
Shoppers switch units in one tap. Measurements convert; size systems like EU or US stay as they are.
Find my size
Shoppers enter their measurements and the matching row lights up. Nothing leaves their device.

Do I need to edit my theme?
No. SizeGrid is a theme app block. Add it once to your product page in the theme editor; it works with Online Store 2.0 themes, including Dawn and Horizon.
What happens to my charts if I remove the app?
They stay in your store under Content → Metaobjects. Reinstall SizeGrid and everything is back, rules included.
Can I move my charts from another size chart app?
Yes. Open a product page with your old chart, select the table, copy it and paste it into SizeGrid. A screenshot works too: SizeGrid reads it with AI.
Does the size finder store body measurements?
No. Measurements are kept only in the shopper's browser so they're filled in on the next product. They are never sent to you or to us.
Is there a fee per order?
No. One flat price, no order-based charges, no import credits to buy.
