Increasing text size on your computer screen is a quick accessibility adjustment that reduces eye strain and makes reading easier - whether you're on a small laptop display or a large desktop monitor. Every major operating system has this built in, and it takes less than a minute to change.

Quick Answer

How do I increase text size on any computer screen? On Windows, go to Settings > Accessibility > Text Size and drag the slider. On Mac, go to System Settings > Accessibility > Display > Larger Text. Both methods increase text size across the system without zooming in or reducing screen resolution.

🔧 Increasing Text Size: Windows 10 and Windows 11

Windows 11:

  1. Open Settings (Win + I)
  2. Go to Accessibility > Text Size
  3. Drag the Text Size slider to the right
  4. Click Apply

Text will scale across most apps and system UI. This uses Windows' built-in text scaling, which is separate from display scaling - it increases text size without changing icon sizes or app layouts.

Windows 10:

  1. Open Settings (Win + I)
  2. Go to Ease of Access > Display
  3. Under "Make text bigger," drag the slider
  4. Click Apply

Alternatively, change Display Scaling: For a more comprehensive size increase across everything (text, icons, buttons), go to Settings > System > Display > Scale and change it from 100% to 125% or 150%. This scales the entire UI proportionally.

📊 Increasing Text Size: macOS

macOS Ventura, Sonoma, Sequoia:

  1. Open System Settings (Apple menu > System Settings)
  2. Go to Accessibility > Display
  3. Click Larger Text and drag the slider
  4. Changes apply immediately

This increases text in supported apps system-wide. For apps that don't respond to the Larger Text slider, use Cmd + Plus (+) to zoom in within that specific application.

Alternative - Reduce Display Resolution: Go to System Settings > Displays and select a lower resolution (e.g., switch from "More Space" to "Larger Text" in the Scaled options). This makes everything on screen physically larger but reduces the amount of content visible at once.

💡 Browser-Specific Text Zoom

If you only need larger text in your web browser:

  • Chrome/Edge/Brave: Ctrl + Plus (+) to zoom in, Ctrl + 0 to reset
  • Firefox: Same shortcuts, plus you can set a default zoom level under Settings > General > Zoom > Default Zoom
  • Safari (Mac): Cmd + Plus (+), or go to Safari > Settings > Websites > Page Zoom to set per-site defaults

For permanent browser zoom, set your preferred level and it will persist across sessions. Most users find 110–125% comfortable on standard 1080p or 1440p displays.

❓ Frequently Asked Questions

Will increasing text size affect my screen resolution? No. Windows text scaling and macOS Larger Text both increase font rendering size without changing your display resolution. Your desktop icons and layout remain at the same size; only text becomes larger.

What's the difference between text scaling and display scaling? Text scaling only affects font sizes in supported applications. Display scaling (also called DPI scaling) scales the entire UI - text, icons, buttons, and windows - proportionally. Display scaling at 125–150% is generally the more useful setting for users who find everything on screen too small.

I increased text size but some apps still show small text. Why? Some older applications don't respond to Windows text scaling or macOS Larger Text settings. For these apps, use the app's own zoom or font size settings (if available), or use your OS display scaling setting instead, which forces scaling at the system level.
