Need to adjust a size chart you've already set up? Maybe you'd like to add a measurement, fix a number, adjust your sizes, or assign the chart to more products. It's quick to do, and your changes appear to shoppers as soon as you save. Here's how:
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 size charts in use.
Under Existing size charts, find the chart you want to change — the list shows each chart's name, the products it's assigned to, and when it was last updated.
Click the chart's name to open it in the editor.
Step 2: Make your changes
You can edit any part of the chart directly:
Change a measurement or size: click into any cell and type the new value.
Rename a column: click into the column header (for example, change "Chest" to "Bust"). 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 measurements or Garment measurements. On garment charts, set Measured flat vs Measured around, How is this garment meant to fit? (Tight / Regular / Relaxed / Oversized), and How stretchy is the fabric? (0–20%). These change how Size Recommender converts the table — you don't retype the numbers.
Add or remove columns and rows as your sizing changes.
Assign or unassign products: update which products show this chart — including Tags, Vendor, and Collections. See How to Link a Size Chart to Specific Products or Collections.
💡 A little tip: because one chart can be assigned to several products, a single edit updates the sizing everywhere that chart is used — that's the beauty of reusable charts.
Step 3: Save
Save your changes and shoppers see the updated chart straight away, on every product the chart is assigned to. If Size Recommender is on, Your size and Estimate my size also follow the new numbers, including a new fit intent or stretch value.
Published vs. unpublished
A chart marked Unpublished in your list isn't visible to shoppers, even if it's assigned to products. Enable the toggle at the top of your size chart to make sure it's published and LIVE.
Want to start fresh instead?
Rather rebuild? Create a new chart from a template with Add new chart (disabled at your plan cap), assign it to your products, and remove the old one from your list via the ⋯ menu. See How to Set Up a Size Chart for Your Products.
