How to Adjust Text Size for Readability in Windows OS Display

Adjusting the text size on your Windows computer display is important for readability and accessibility. With some simple settings changes, you can customize the text to be exactly the size you need for your preferences and situation. Whether you want larger text for easier reading or more screen real estate with smaller text, Windows provides the tools to tweak things to your liking.

Why Text Size Matters for Readability

The default text size that Windows chooses does not work for everyone’s needs. Those with impaired vision often require larger text. Even those with perfect vision may strain to read small text, especially on high-resolution or very large monitors.

Additionally, the distance you sit from the screen impacts what text size works best. Sitting further away means you need larger text to comfortably read it.

Optimizing text size ultimately comes down to personal preference for what feels most readable without eye strain. Taking the time to customize it pays dividends in less squinting and eye fatigue.

Adjust Text Size for the Entire Display

The easiest way to change the text size is to adjust it for the entire display. This globally changes the text across Windows and applications.

Here are the steps:

  1. Open the Settings app
  2. Navigate to Accessibility
  3. Select Text Size
  4. Use the Text Size slider to adjust up or down
  • Moving right increases text size
  • Moving left decreases text size
  1. Preview the sample text to test readability
  2. Click Apply to save the changes

This slider globally adjusts the text size from the smallest viable size up to a very large size. Set it based on your personal preference and visual acuity.

Adjust Text Size for Just Windows Menus and Text

If you only want to change the text size in Windows itself, there is a separate setting for that. This leaves application text alone but makes Windows menus and text larger or smaller.

Here are the steps:

  1. Open the Settings app
  2. Navigate to Accessibility
  3. Select Text Size
  4. Scroll down to the Text Size section
  5. Adjust the slider under Make Text Bigger to desired size
  • Moving right increases text size
  • Moving left decreases text size
  1. Preview the sample text
  2. Click Apply to save

This specifically targets the Windows UI text size. Desktop icons, title bars, menus, message boxes and more are impacted. But it leaves websites, documents, and applications alone to manage text size themselves.

Adjust Text Size for Specific Programs

For individual applications where the text size needs tweaking, you can adjust text size within the application itself. How to do this varies by program.

Many applications have zoom controls or text size options in the menus or preferences that control text display. Learning where these options hide in your commonly used applications is worthwhile for finetuning text size on an app-by-app basis.

Use Display Scaling for Global Size Adjustments

Alongside overall text size, Windows 10 has display scaling settings that adjust the size of all elements globally. This includes text, icons, windows, menus and more.

To use display scaling:

  1. Go to Settings
  2. Choose System
  3. Select Display
  4. Under Scale and Layout, adjust the slider for your display
  • Moving right makes everything larger
  • Moving left makes everything smaller

This is useful when using very high resolution displays where everything is too small at the default sizes. Increasing scaling globally can make the entire Windows experience easier to see and interact with.

Tweak DPI Scaling Settings

To tweak advanced scaling settings on a per-monitor basis, you can dig into the DPI scaling settings.

Here are the steps:

  1. Go to Settings
  2. Choose System
  3. Pick Display
  4. Scroll down and enable Advanced scaling settings
  5. Adjust the sliders individually for each monitor

This allows you to cater the scaling to each monitor’s size, resolution, and personal preferences.

Use Magnifier for Zooming In

Windows includes a Magnifier accessibility tool that zooms parts of the screen. This can be useful for zooming in on specific text elements that need to be larger to read comfortably.

To use Magnifier:

  1. Hit the Windows key + Plus to launch and zoom in
  2. Continue hitting Windows + Plus to continue zooming in
  3. Hit Windows + Minus to gradually zoom back out
  4. Hit Windows + Esc to close Magnifier

Magnifier is helpful for quick zooming for reading small print and won’t permanently impact text size.


Optimizing text size for your display and preferences is a vital part of establishing readable text without excessive eye strain. Take advantage of Windows’ scaling options to customize text on a global or app-by-app basis. Finding the right balance leads to a more comfortable and accessible computing experience.
