Can a shopper who zooms in still buy from you?
Roughly one shopper in twelve enlarges text on their phone. We read your storefront and your theme's main stylesheet and look for the things that shut those people out — a viewport tag that kills pinch-zoom, px-locked type, containers wider than a 320px screen.
Based on publicly available data only. Informational, not legal advice.
What this checks
- Whether the viewport meta tag disables pinch-zoom (user-scalable=no, or maximum-scale under 5)
- Whether a viewport tag exists at all, and whether it is pinned to a fixed width
- How much of your theme CSS hard-codes font sizes in px instead of rem/em
- Fixed-width containers wider than 320px that carry no max-width
- Global overflow-x:hidden on html/body — which hides the sideways scroll instead of fixing it
- white-space:nowrap sitting on body-text selectors
- Elements with a pixel width written straight into their inline style attribute
FAQ
Does a clean result mean I pass WCAG 1.4.10 Reflow?
No. Reflow is defined as content still working at a 320 CSS pixel width — the equivalent of 400% zoom on a 1280px screen. Proving that requires actually rendering the page at that width and looking for two-dimensional scrolling. We do not run a browser, so that specific item always comes back as “could not tell”. What we can do is find the causes that produce those failures, which is most of the work.
You only read one stylesheet. Isn't that a partial picture?
It is, and we say so in the report. We take the theme's largest stylesheet on Shopify's CDN plus any <style> blocks in the page, which is where the layout rules live in every theme we have seen. Rules in a component file we did not open, or injected by an app at runtime, are not counted — so treat the counts as a floor, not a total.
Why does this matter commercially, not just legally?
A blocked pinch-zoom on a product page means someone who cannot read your size chart leaves instead of asking. It is also the cheapest accessibility item to fix — the viewport tag is one line in theme.liquid. The legal side is real too: EN 301 549 points at WCAG 2.1 AA, and the European Accessibility Act's requirements apply from 28 June 2025.
Want the theme fixed so it holds together when text is enlarged?
We are a Shopify studio. The audit is free; the fix is yours to make — or ours to ship.
