Fewer “which size?” emails. Clearer sizing.

|---|---|---|

Everything a size chart needs
And nothing that slows your store down.
Copy the cells from Excel, Google Sheets or Numbers and paste. Columns, rows and units come across; edit any cell after.
Shoppers switch units in one tap. Ranges like 82–87 and fractions like 32½ convert and round the way you choose; size labels stay put.
Assign by product, collection, tag, product type or vendor, plus a default. Clear priority rules, and a checker that tells you which chart a product gets and why.
Tops, bottoms, dresses, women's and men's shoes with US/UK/EU sizes, and rings with diameter and circumference.
Labelled dialog, focus kept inside, Esc to close, focus returned to the link. Proper table headers for screen readers, and a bottom sheet on phones.
Charts live in your store's own metafields and the chart for each product is picked by your theme. No calls to our servers and no layout shift.
One product, one chart — always the right one
When a product matches several charts, the most specific assignment wins.
| Order | Assigned by | Example |
|---|---|---|
| 1 | Product | The oversized hoodie gets its own chart |
| 2 | Collection | Everything in “Denim” gets the jeans chart |
| 3 | Product tag | Products tagged “relaxed-fit” |
| 4 | Product type | All “Ring” products get the ring sizer |
| 5 | Vendor | A brand you resell with its own sizing |
| 6 | Default | Your general chart for everything else |

Questions merchants ask
Where does the size chart link appear?
Switch on the Size chart (automatic) app embed and the link appears next to the variant picker on every product that has a chart. Prefer to place it yourself? Add the Size chart block to your product page in the theme editor and drag it anywhere.
What if a product matches more than one chart?
The most specific assignment wins: a chart picked for the product itself, then collection, tag, product type, vendor, and finally your default chart. If two charts match at the same level, the one higher in your list wins, and you can reorder the list. The Which chart does a product get? checker shows the result for any product.
How does the cm/inch conversion work?
Tick Convert on the columns that hold measurements. When a shopper switches units, every number in those cells is converted — including ranges (82–87), lists (32/34) and fractions (32½, 32 1/2) — and rounded to your chosen step, like the nearest half inch. Size labels like S, M or US 8 never change. The shopper's choice is remembered on their device.
Will it slow down my product pages?
No. Your charts are published to a metafield in your store, and your theme picks the right chart while it renders the page. The script is a few kilobytes, loads deferred, and does nothing until the chart is opened. The link is rendered in place, so nothing jumps.
Can I add a measuring guide?
Yes: add how-to-measure text and an optional image (upload it to Content → Files and paste its link). It shows under the chart in the pop-up, with a note line for fit advice.
Which themes are supported?
Online Store 2.0 themes, including Shopify's free themes. The app embed finds the variant picker in common themes; if yours is different, type a CSS selector in the embed's settings or use the block instead.
