Respect enlarged system text on mobile

What to change

Ask for mobile acceptance checks that include enlarged system text and the browsers your audience actually uses.

A worked example

Illustrative example

A visitor's preferred larger text makes a contact form longer, but labels wrap, fields remain associated with them and the submit action stays accessible.

How to check the result

Accept when supported mobile settings preserve essential information and functionality throughout the journey, including error and expanded states.

A mistake to avoid

A responsive preview changes screen dimensions but may not reproduce the browser's handling of the user's actual text preferences.

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 recordUse a real phone with a larger text preference and open navigation, forms and confirmation screens. Look for clipped labels and controls pushed outside panels.Rotate the phone and repeat the most crowded screen. Ask the supplier to distinguish system text behaviour from a desktop viewport simulation.Complete the core enquiry task without resetting the preference. Confirm validation, help and final actions remain readable and reachable.
