How to Change Font Size on Samsung Galaxy A57
If the text on the Galaxy A57 feels small, the fix is a single slider in Display settings. It takes effect everywhere at once — Settings, messages, apps — and the recording moves it one step larger, which is the change most people actually want.

Steps
Open Settings

Tap Display
In Settings, tap Display.
Tap Font size and style
On the Display page, scroll down and tap Font size and style.
Drag the slider one step larger
Drag the font size slider at the bottom one notch toward the larger A on the right.
Check the preview
The preview card at the top — Main text will look like this — shows the new size as you drag. The change applies immediately; there is nothing to save and no restart.
Good to know
- Bold font is a separate switch on the same page — combined with one slider step it makes text markedly easier to read.
- Font size only scales text. Screen zoom (also under Display) scales icons and layout elements as well, if you want everything bigger.
