How to make text bigger on your iPhone or Android phone

The fast take: You can make your phone easier to read without buying anything. Start with the text-size setting, then check a familiar message. On iPhone, look under Accessibility. On Android, search Settings for Font size. Some apps won’t follow your chosen size, so check the apps you use most.

You don’t have to change everything at once. Try one small adjustment, use the phone for a moment, then decide whether it helps. If you’re helping someone else, let them choose the size.

How do I make text bigger on an iPhone?

1. Open Settings.
2. Choose Accessibility, then Display & Text Size.
3. Tap Larger Text.
4. Move the slider until the writing feels comfortable.
5. For more size choices, turn on Larger Accessibility Sizes.

You can also try Bold Text on the Display & Text Size screen. This makes lettering heavier rather than simply larger.

Apple says the preferred size works in supported apps. These include Messages, Mail, Calendar, Notes and Settings. It isn’t a promise that every app will change. These steps come from Apple’s guide to making text easier to read.

How do I make text bigger on Android?

1. Open your phone’s Settings app.
2. Use its search box to look for Font size.
3. Open the matching setting and move the slider.
4. Check the preview before returning to a familiar app.

If other items also feel too small, search Settings for Display size. This has its own slider. Start with text size alone so you can judge what changed.

Google also documents Bold text under Accessibility, then Display size and text. Some apps won’t use that setting either.

Menu names can vary between phones. Google’s instructions note that some steps need Android 13 or later. Use the Settings search rather than assuming every phone has identical menus. See Google’s text and display settings guide.

What should I check after changing the size?

Don’t judge the result from the settings preview alone. Try the tasks you do every day:

1. Read a message from someone you know.
2. Open your contacts and find a familiar name.
3. Look at a calendar appointment.
4. Open a favourite app and check its main buttons.

Ask yourself whether reading feels easier. Can you still find what you need? If the layout feels cramped, return to the same slider and try a slightly smaller setting.

What are the catches?

Not every app will match. If one app still looks small, check its own reading or display options. Don’t assume you changed the phone incorrectly.

Bigger isn’t always better. Choose the smallest increase that feels comfortable, then adjust again if needed. The goal is easier everyday use, not reaching the end of a slider.

You don’t need a paid “large text” app for these steps. Use the phone’s own Settings app. Don’t install something from an advert just to follow this guide.
