Need to adjust a size chart you've already set up? Maybe you'd like to add a measurement, fix a number, or assign the chart to more products. Changes appear to shoppers as soon as you save.
Step 1: Open the chart
In your Shopify admin, go to Apps → AI Frame – Virtual Try-On, then click Size Chart in the app's left menu. The header shows X of Y published size charts.
Under Existing size charts, find the chart you want to change — name, assigned products, last updated. Imported charts may still be drafts.
Click the chart's name to open it in the editor.
Step 2: Make your changes
Change a measurement or size: click into any cell and type the new value.
Rename a column: click into the column header. A Height Range column can power a size recommendation from height.
Switch units: next to the size table, choose cm or inches. Switching converts the numbers already in the table.
What do these measurements describe?: Body or Garment. On garment charts, set Measured flat vs around, How is this garment meant to fit?, and How stretchy is the fabric? (0–20%).
Add or remove columns and rows.
Assign or unassign products: including Tags, Vendor, and Collections.
💡 Because one chart can be assigned to several products, a single edit updates sizing everywhere that chart is used.
Step 3: Save
Save your changes and shoppers see the updated chart on every assigned product. If Size Recommender is on, Your size and Estimate my size also follow the new numbers.
Published vs. unpublished
A chart marked Unpublished isn't visible to shoppers, even if it's assigned. Enable the toggle at the top of the chart to make it live. Store and photo imports start as drafts on purpose.
Want to start fresh instead?
Create a new chart with Add new chart (disabled at your published cap: Free 10 / Starter 30 / Growth 100 / Advanced unlimited), assign it, and remove the old one via the ⋯ menu. See How to Set Up a Size Chart for Your Products.
