Allow visitors to enlarge the page with familiar gestures

What to change

Ask the supplier to retain user enlargement and make the layout usable when visitors choose to magnify it.

A worked example

Illustrative example

A visitor enlarges a detailed instruction beside a form field, reads it, then returns to the form without losing the information they entered.

How to check the result

Accept when supported browsers permit useful enlargement and the main journey remains operable before, during and after magnification.

A mistake to avoid

A dedicated larger-text switch can help some readers but does not automatically replace the browser and device controls they already use.

Your action checklist

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.

Decisions to recordOpen representative pages on a real phone and attempt to enlarge them using ordinary browser gestures. Include forms and any embedded task interface.Inspect the enlarged result for hidden controls and content that cannot be reached. Ask the supplier to separate zoom restrictions from underlying layout defects.Return to the normal scale and continue the task. The transition should preserve field values, selections and the visitor's current state.
