In short

Open Settings, Display, Font size and style and drag the slider at the bottom to the right. Switch on Bold font for thicker letters, and tap Font style to choose another font. The preview at the top shows the result straight away.

Well, if you find yourself holding the phone a little further away to read a message, it is the phone that needs to change, not you. Samsung says making the text bigger is quick if you're struggling to read it.

If you do not see this option

  • Font size and style looks different Samsung says the menus and options may look a little different depending on the model and software version. Update first under Settings, Software update. Source: How to change font size and style on a Galaxy phone
  • You want the letters to stand out, not grow Samsung suggests Settings, Accessibility, Vision, High contrast text, which draws an outline around all text. Source: How to change font size and style on a Galaxy phone
  • Want icons and buttons bigger too? Font size only changes text. Samsung's US guide describes Screen zoom, under Settings, Display, which makes items on the screen appear larger. Adjust its slider at the bottom. On a Z Fold phone it is called Screen layout and zoom. Source: Adjust your Galaxy phone or tablet's display settings

If this does not work

  • The new size does not show everywhere Don't worry, some screens just need a fresh start. Samsung says to restart the phone if a change does not apply straight away.
  • A new font will not download Samsung says to make sure there is enough free storage, and suggests Wi-Fi, because downloads over mobile data may cost money.
  • Text is cut off or overlaps in an app? At the largest sizes some apps run out of room, so words are cut short or buttons overlap. Move the slider one step back, or use Screen zoom at a lower setting together with a medium text size.
  • One app ignores the new size? Samsung suggests checking Google Play Store or Galaxy Store for app updates, since some apps might need one.

Good to know

Still hard to read? Settings, Accessibility, Vision, High contrast text adds an outline to all text.

The new size applies across the phone at once: Settings, the Home screen labels, messages and most apps. It has no effect on battery or storage. To undo it, drag the slider back towards the small A.

For a quick close look at something small, such as a photo detail or tiny print, magnification works better than a permanently larger size. See zoom in on a Samsung Galaxy screen with magnification. If your eyes get strained, Samsung's US guide says Dark mode can make the screen easier to see.

The screenshots are from a Samsung Galaxy S26 with One UI 9.0 and Android 17, in Dark mode, apart from step 1, from our Galaxy A57 with One UI 9.0. On other Galaxy phones, Samsung says the menu layout and options may vary slightly by model and software version. We only looked at these screens on our phones and changed nothing.
