Free size audit · Shopify fashion stores

How clearly does your store tell shoppers their size?

A score, your own products marked up, and what to fix first. Ready in seconds.

  • No install or sign-up
  • Public pages only
  • Nothing stored

What the audit checks

Six things that decide whether a shopper picks a size.

Checked against what your store actually publishes.

Size-guide links

Every link should open a guide, not “page not found”.

Sizes against the guide

Every size you sell should be in your chart.

Units

Centimetres, inches, or both, and what each one measures.

Size labels

One size, one spelling. “UK12” and “UK 12” split your filters.

Fit notes and model size

“True to size” or “model wears M” settles close calls.

Readable charts

Charts drawn by an app can be invisible to search and AI shopping.

Questions

Plain answers.

For a manual check, use the size-chart checklist. To see what AI shopping assistants receive, run the AI agent fit check.

Is the audit free?

Yes. There is no charge, no sign-up and nothing to install. Enter your store address and the report appears in a few seconds.

What does it read?

Only what any shopper can see: your public product feed (the first 250 products), your home page, three product pages and up to three size-guide pages your store links to. It never signs in.

Do you store my data?

No. The audit runs when you ask for it and nothing is saved. A shared report link simply runs the audit again.

Why can't it check my sizing app's chart?

Apps such as Kiwi Sizing draw their chart in the browser after the page loads, so it is not in your page HTML. The report tells you when that is the case.

Does the score predict my returns?

No. It describes the size information you publish, not your returns or sales.
