How to Change Font Size on Facebook

Facebook usually follows your device accessibility text settings and browser zoom, not an in-app font-size slider. If text is too small, adjust your phone or desktop display settings first, then reopen Facebook.

1. Open Settings.
2. Go to Display & Brightness → Text Size.
3. Move the slider right to increase text.
4. For larger jumps: Accessibility → Display & Text Size → Larger Text.
5. Close and reopen Facebook.

Messenger has its own separate control, scoped to just that app: add Text Size to Control Center (Settings → Control Center), then swipe it open, tap Text Size, and choose "Messenger Only" to resize chat text without changing the rest of iOS.

1. Open Settings.
2. Go to Display.
3. Adjust Font size and optionally Display size.
4. Reopen Facebook and test readability.

Phone vendors label menus differently, but these controls are always in Display or Accessibility settings.

Use browser zoom:

• Windows / Linux: Ctrl + +
• macOS: ⌘ + +
• Reset: Ctrl/⌘ + 0

This one isn't a setting at all. Facebook automatically enlarges short, plain-text status updates — no photo, link, or other attachment, and roughly under 85 characters — into a bigger display font for everyone who views the post. It's a native "Big Text" behavior, not something you toggle on or off.

If you want the effect: keep the post short and text-only. If you want to avoid it: add a photo, a link, or simply write past the character threshold.

If you meant "stylish text" (bold, cursive, bubble) rather than larger text size, use the Facebook generator below.
