Step by step

1. 

   Open Font size and style

   Settings, Display, then scroll to Font size and style.

   Watch these steps Done

2. 

   Drag the size slider

   The slider at the bottom changes the size; the preview at the top shows how main text will look. Ours was on the third step.

   Done

3. 

   Make text bold

   Bold font makes all text heavier, which can help as much as a bigger size. It was off on ours; switched on, the preview text turned bold. We switched it back off.

   Done

4. 

   Change the font style

   Font style picks the typeface. Ours was Default.

   Done

5. 

   Make everything bigger with Screen zoom

   Back on the Display page, Screen zoom enlarges icons, buttons and text together.

   Ours sat on the second of five steps.

   Done

6. 

   Or try Easy mode

   Easy mode, further down the Display page, switches to a simpler layout with larger items.

   Done

• You want a different font Samsung says to tap Font style, then Download fonts. Galaxy Store opens with fonts to install; on mobile data the download can cost extra. Source: How to adjust the font size and style on your Galaxy phone
• The biggest size is still hard to read Samsung suggests Settings, Accessibility, Visibility enhancements and the switch for High contrast fonts, which adds an outline to all text, including the lock screen clock. Source: How to adjust the font size and style on your Galaxy phone

If this does not work

• Text in one app stays small Some apps, such as browsers, have their own text size setting. Change it in that app, or use Screen zoom in step 5 to enlarge everything. Source: How to adjust the font size and style on your Galaxy phone

About this guide

Text that is too small, or too big, is set in one place on a Galaxy. The preview at the top shows the new size before you leave the page.

We switched Bold font on for one picture and back off. Steps 3 and 5 are from the same phone after its One UI 9 update (Android 17).

Good to know

Some apps, such as browsers, have their own text size setting that this does not change.

Screen colours look wrong instead? Samsung Galaxy screen turned black and white? How to fix it.

In short: Settings, Display, Font size and style: drag the slider, Bold font if you like. Screen zoom for everything.
