The right chart on every product, without editing one
Rules choose where each chart shows: by tag, type, vendor or collection, by words in the title, by SKU, or by country. You see the products it will show on before you save, and a report lists every product that still has no chart.
Simple rules, or precise ones
Most stores need one line: all products, or a tag. Others need more, and it’s there.
Everywhere, or chosen products
All products, chosen tags, vendors, types or collections, or a hand-picked list.
Conditions
Title or handle contains, starts with, ends with, is or isn’t, combined with AND or OR. SKU too.
Exclusions and priority
Leave out tags, vendors, types, collections or products, and decide which chart wins when two match.
By country
Show a chart only to shoppers of chosen countries, as set by your store’s country selector.
Placed next to the size option, by itself
Turn on the app embed in one click: on 25 of the 26 themes most used by stores with size charts, the guide link lands next to the size option on its own. Or drag the app block exactly where you want it in the theme editor.
Your old app’s spot
Coming from another size chart app? The guide shows where the old link was, and the old link is hidden until you uninstall it. From Kiwi, MP or BF, it also keeps the old link’s style: button or link, text and icon.

Product rules: questions
Do I have to edit my products?
No. Rules read your tags, types, vendors, collections, titles and SKUs. You never open a product to attach a chart.
Can I show different charts in different countries?
Yes. Each chart can be limited to a list of countries, matched with the country your store’s selector shows.
What if two charts match the same product?
Both show, as tabs, the highest priority first. Set the priority in the chart, or exclude the product from one of them.
Does it work with my theme?
Yes: an app block for every Online Store 2.0 theme, an app embed for older ones. If the link isn’t where you want it, we place it for you, for free.
