Make text bigger on a Samsung phone

You can make your phone more comfortable to read without buying an app. Font size changes lettering; screen zoom changes the size of screen items. Start with one small adjustment. Names and available controls vary across Samsung Galaxy models and One UI versions.

Before you start

  • Unlock your already configured phone and open a screen you find difficult to read.
  • Remember the starting slider position so you can return to it if needed.

Step 1 of 6: Open Display settings

Open Settings and tap Display. If the list looks different, use Settings search to look for Font size. Choose the matching setting rather than an advertisement or download.

Step 2 of 6: Find the font control

Tap Font size and style. Older phones may use a name such as Font size or Font and screen zoom. Look for the font-size slider and its preview text.

Step 3 of 6: Increase the size gently

Move the font-size slider a little towards the larger end. Read the preview. Make another small adjustment only if needed, and tap Apply if your version shows that button.

Step 4 of 6: Check a real screen

Return to Settings or a familiar message. See whether you can read it comfortably and whether lines wrap acceptably. If the result feels too large, return to the same slider and reduce it slightly.

Step 5 of 6: Consider screen zoom

If buttons and other items still feel small, return to Settings, Display and open Screen zoom. A Galaxy Z Fold may label this Screen layout and zoom. Increase its slider slightly, then check again.

Step 6 of 6: Keep the useful setting

Open two apps you use often and compare them. Keep the adjustment that helps you read and tap comfortably. Write down the route to the setting so you can change it again later.

Try it for yourself

Your small practice task.

Increase font size one small step and check Settings plus an app you use every day.

A common question.

Why is a website or picture still hard to read?

Text drawn inside a picture cannot be resized like ordinary app text. Websites and apps can also have their own display controls. Use the app's reading or zoom options when available.
