One of the most useful things about AI Frame's size charts is that they're reusable: you build a chart once and link it to as many products as you like. This is how you decide where a chart appears — not the same as Exclude product types, which only hides the Try On pill.
Where you link a chart
Open the chart (in Size Chart in the app's left menu, click the chart or create a new one) and scroll to Assign to products. You'll see six options:
Option 1: All products
The chart shows on every product in your store. Handy if you sell one type of item with consistent sizing. The editor confirms: “This chart will appear on every product in your store.”
Option 2: Specific products
Pick the exact items:
Select Specific products.
In Search to add products, type a product's name and click Search.
Click Add on the products that should use this chart.
Perfect when different products need different sizing — your “Men's T-Shirts” chart on the tees, your “Hoodies” chart on the hoodies.
Option 3: Specific categories
Assign by product category, and the chart applies to everything in it. New products added to that category later are covered automatically. The list comes from your Shopify catalog.
Option 4: Tags
Under Product tags, enter comma-separated tags (for example summer, sale, mens). Then set Match mode:
ANY — the product has at least one of the listed tags.
ALL — the product has every listed tag.
New products with those tags pick up the chart automatically.
Option 5: Vendor
Enter comma-separated vendor names (case-insensitive), for example Nike, Adidas. The chart applies when the product's vendor matches any listed value — useful for multi-brand stores.
Option 6: Collections
Search collections by name and add them. Then set Match mode: ANY = the product is in at least one selected collection; ALL = the product is in every selected collection. New products you add to those collections are covered automatically.
Click Save chart and the chart appears on everything you've linked. Shoppers then see Size Chart next to the Size option, and (on Starter and above, with Size Recommender on) Estimate my size / Your size above Add to cart.
How to think about it
A simple rule: one chart per sizing group, not per product. All your tops that share the same measurements should share the same chart. That way you maintain a handful of charts instead of hundreds, and a sizing update is one edit everywhere.
A Height Range column on the chart can still power a size recommendation from height, even on garment-measurement charts. On garment charts, also set How is this garment meant to fit? and How stretchy is the fabric? so recommendations convert the table correctly.
💡 A little tip: name each chart after its sizing group (“Women's Tops”, “Unisex Hoodies”) so it's always obvious what links where.
What if a product has no chart linked?
Shoppers on that product won't see Size Chart next to the size picker, won't see Estimate my size / Your size, and won't see the chart in the widget. Try-on still works as normal. Start with your best-sellers.
Plan note: the Size Chart page shows X of Y size charts in use. Free includes 1 chart (Add new chart disabled at the cap), Starter 10, Growth 20, Advanced unlimited. One chart can still link to as many products as you like.
