WCAG 1.4.4: Resize Text

Quick answer: Text must remain readable and functional when users zoom up to 200 percent without needing assistive technology.

What This Means

On ecommerce sites, Resize Text usually shows up in repeating storefront components such as product cards, PDP media, search results, cart drawers, checkout forms, and support content. If the live experience depends on patterns like coupon-code text clips inside a fixed-height input row at browser zoom. or sticky buy bars overlap product titles when text is enlarged., disabled shoppers can lose context or get blocked before purchase.

This criterion matters because D2C teams often fix the homepage but miss reusable app blocks, campaign pages, and mobile-specific UI. The practical standard is simple: build the same outcome for keyboard users, screen-reader users, low-vision users, and anyone relying on captions, labels, structure, or predictable behavior.

For Shopify, WooCommerce, and custom storefronts, the fastest remediation path is usually template-level work. Fix the repeated component once, then retest every place it appears across browse, buy, and post-purchase journeys.

Common Violations on Ecommerce Sites

• Coupon-code text clips inside a fixed-height input row at browser zoom.
• Sticky buy bars overlap product titles when text is enlarged.
• Account settings labels truncate and hide save buttons at 200% zoom.
• Mega-menu columns collapse so category text becomes unreadable.

How to Fix It

Start with the live customer journey, not isolated components in Storybook or Figma. Audit the problem on category pages, product detail pages, quick views, cart, checkout, account, and help templates.

1. Use relative sizing and flexible containers instead of fixed pixel heights.
2. Let text wrap in navigation, buttons, and PDP widgets rather than clipping it.
3. Check zoom behavior in desktop browsers for cart drawers, modals, and account pages.
4. Reserve icons and badges enough space so enlarged text does not collide with them.

On Shopify, fix the theme section or app block that repeats the defect. On WooCommerce and WordPress, update the template override or plugin output. In custom React or headless storefronts, move the fix into shared components so merchandisers cannot reintroduce the issue with every campaign.

Code Example

<!-- Before -->
.promo { height: 40px; overflow: hidden; }

<!-- After -->
.promo { min-height: 40px; overflow: visible; }
