Make your phone easier to read in a few small steps

Pick a real screen to improve

Open something you often read: a message, a recipe, or your calendar. Ask yourself what would make it more comfortable. Are the letters too small? Are they too thin? Do you want the buttons and other items larger as well? Answering that first makes the settings menu feel much less like guesswork.

Before changing anything, make a note of the setting you started with. Adjust one thing, return to your chosen screen, and compare. You can keep a change that helps and reverse one that does not. There is no prize for using the factory default or for choosing the largest option.

On iPhone: enlarge the text

Apple's accessibility settings offer a direct route: open Settings, choose Accessibility, then Display & Text Size. Tap Larger Text and move the slider to a size you like. If you want more choices at the larger end, turn on Larger Accessibility Sizes.

Return to Display & Text Size to try Bold Text separately. Apple says the preferred text size applies to supported apps, including Messages, Mail, Calendar, Notes, and Settings. An app that does not support the feature may behave differently. These controls change presentation; they do not rewrite your messages or documents.

On Android: use the Settings search

Google's instructions use a useful approach across different menus: open Settings, search for Font size, select the result, and move the slider. If you want screen items larger too, search Settings for Display size and adjust that slider separately.

For heavier lettering, Google's documented route is Settings, then Accessibility, then Display size and text, then Bold text. Menu names and available options can vary with the phone and software version. Google notes that some steps require Android 13 or later, and that some apps do not follow the font-size or bold-text setting. Use the phone manufacturer's own help if your menus differ.

Try an ordinary day on the new setting

A preview is a helpful start. Your usual activities are a better final check. Read a message with several lines, look at tomorrow's calendar, and open a page you regularly use. Give yourself time to notice whether the change actually suits you.

If the largest text feels cumbersome, try a step down and compare. You might prefer moderately larger text with bold lettering, or larger text on its own. Make this a small experiment rather than an afternoon spent adjusting every option on the phone.

• Can you comfortably read a full sentence?
• Can you find the button you need?
• Do your most-used screens still feel straightforward?
• Does the setting work where you normally use the phone?

When one app still looks small

An unchanged app does not necessarily mean you missed a step. Both Apple and Google describe limits to how broadly text settings apply. Check that app's own settings or its official help for reading and display options. Avoid assuming that a setting for one app must work the same way in another.

When you find a combination you like, jot down the names of the settings and your choices. That note can save some trial and error after changing phones. You can also revisit the settings whenever your preferences change. The aim is an everyday screen that feels comfortable to you, with a simple route back if you want to adjust it again.
