How to Make Text Bigger and Easier to Read on Any Phone

Squinting at a phone screen, holding it at arm’s length or hunting for reading glasses every time a text arrives gets old fast. The fix is usually not a bigger phone. Every iPhone and Android phone already has several built-in ways to make text larger, bolder and easier to read, and most take less than a minute to set up.

The trick is knowing which setting does what. Text size makes words bigger. Display zoom makes everything bigger, including icons and buttons. The magnifier turns the camera into a reading aid for paper menus and medicine labels. And simplified modes strip the phone down to large, clear buttons. This guide walks through each one on both platforms.

Which setting do you need?

Menu names can vary by phone model and software version. If a path does not match exactly, use the search bar at the top of the Settings app and type “text size” or “font size.”

How to make text bigger on iPhone

Change the text size

1. Open Settings.
2. Tap Display & Brightness, then Text Size.
3. Drag the slider to the right until text is comfortable.

Apple says this changes text in apps that support Dynamic Type, including Mail, Contacts, Calendar, Phone and Notes, and in many third-party apps.

Go even larger

If the largest standard size is not enough:

1. Open Settings > Accessibility > Display & Text Size.
2. Tap Larger Text and turn on Larger Accessibility Sizes.
3. Drag the slider to choose a size.

Very large text can push buttons off screen in some apps. If controls become hard to tap, step down a size.

Set text size for one app only

You can add a Text Size control to Control Center, then open the app you want, swipe down to open Control Center, tap the control and choose the option to apply the size only to that app. This is useful if one app, such as a news reader, needs bigger text while others look fine.

Make text bold and clearer

• Turn on Bold Text under Settings > Display & Brightness, or Settings > Accessibility > Display & Text Size.
• In the same Accessibility menu, try Increase Contrast and Button Shapes to make buttons and links easier to spot.

Enlarge everything with Display Zoom

Go to Settings > Display & Brightness > Display Zoom and choose Larger Text. The phone restarts its display with bigger icons, buttons and text, at the cost of showing less on screen at once.

How to make text bigger on Android

Android phones from different makers name things differently, but the core settings are the same. Google’s own instructions recommend searching Settings for the setting name.

Change font size

1. Open Settings.
2. Search for Font size, or go to Display > Display size and text on Pixel phones.
3. Drag the slider to the right.

Google notes that the font setting does not apply in some apps.

Go up to 200%

On recent Android versions, you can add a Font Size tile to Quick Settings. Swipe down from the top of the screen, tap the tile and drag the percentage slider. Google says this lets you increase font size up to 200%, and newer Android versions scale large text in a way that keeps already-large headings from becoming oversized.

Change display size

Search Settings for Display size and drag the slider. This makes icons, buttons and text bigger together, similar to Display Zoom on iPhone.

Bold and outlined text

• Go to Settings > Accessibility > Display size and text and turn on Bold text.
• On Android 16 and later, Outline text adds an outline around text for better contrast. Earlier versions offer High contrast text instead.

Key takeaway: Start with text size, then add bold text. If buttons and icons are also hard to see or tap, use display size or Display Zoom. Save the magnifier and simplified modes for when those 2 settings are not enough.

Zoom and magnifier tools

Zoom into any part of the screen

Sometimes you need to zoom into one small thing, like a photo caption or a tiny link, without changing everything.

• iPhone: Turn on Settings > Accessibility > Zoom. Double-tap the screen with 3 fingers to zoom in, and drag 3 fingers to move around.
• Android: Go to Settings > Accessibility > Magnification and choose a shortcut, such as a triple-tap on the screen or an accessibility button. Then use 2 fingers to pan and pinch to adjust zoom.

Use your camera as a magnifying glass

Both platforms include a magnifier that uses the camera to enlarge real-world text.

• iPhone: Open the Magnifier app, or search for it from the Home Screen. You can freeze the image, adjust brightness and contrast, and turn on the flashlight for dim restaurants.
• Android: Many phones include a Magnifier app or a magnifier shortcut in Quick Settings, including Google’s Magnifier app on Pixel phones. Samsung phones include a magnifier option too.

This is the setting people are most surprised by, and it is ideal for medicine labels, receipts and menus.

Simplified modes for a cleaner, larger layout

If the problem is not just text size but a cluttered screen with too many small options, a simplified mode can help. These are especially useful when setting up a phone for a senior or someone with low vision or cognitive challenges.

• iPhone: Assistive Access. Go to Settings > Accessibility > Assistive Access > Set Up Assistive Access. Apple describes it as a simplified iPhone experience with focused apps such as Calls, Camera, Messages, Photos and Music. You choose either a Rows layout, an easy-to-read list, or a Grid layout with bigger items. A separate passcode is used to exit.
• Google Pixel: Simple View. Go to Settings > Accessibility > Simple View and turn on Use Simple View. Google says it applies larger text and icons, a simplified Home screen, simplified 3-button navigation and higher touch sensitivity. Turning it off restores your previous settings.
• Samsung Galaxy: Easy mode. Go to Settings > Display > Easy mode. It enlarges icons and text, simplifies the Home screen and lengthens the touch-and-hold delay to prevent accidental taps. Availability varies by model.

Other settings that make reading easier

• Turn up brightness or use auto-brightness. Dim screens make small text harder to read.
• Try dark mode. Some people find light text on a dark background easier on the eyes; others prefer the opposite. Try both.
• Use speak screen or read aloud. On iPhone, turn on Speak Screen in Accessibility > Spoken Content. On Android, Select to Speak reads selected text aloud. These help with long articles. Our guide to assistive technology for dyslexia covers more reading tools.
• Zoom in browsers. Both Safari and Chrome let you increase page zoom for websites that ignore system text size.
• Make the keyboard easier to use. Bigger text often enlarges the keyboard too, and Samsung’s Easy mode includes a high-contrast keyboard option.

If websites stay hard to read even with these settings, the site may not follow accessibility guidelines. Business owners can check their own sites against our web accessibility checklist.

Where to start: 5-minute setup

1. Increase text size 1 or 2 steps and live with it for a day.
2. Turn on bold text if letters still look thin.
3. Increase display size or Display Zoom if icons and buttons are also too small.
4. Set up the camera magnifier shortcut for menus and labels.
5. Try a simplified mode if the phone still feels overwhelming.

When you set up a new phone, add these to your checklist of phone settings to change on a new phone. And if hearing is also a challenge, our guide on choosing and setting up OTC hearing aids covers phone pairing.

The bottom line

You almost never need a new phone to read it comfortably. Text size and bold text fix most problems in under a minute. Display zoom handles small buttons and icons, the magnifier covers paper and labels, and simplified modes like Assistive Access, Simple View and Easy mode turn a busy phone into a calm, large-button device. Start small, adjust over a day or two, and change only what helps.
