Why Adjusting Your Mac's Display Matters

How to increase screen resolution on Mac for better readability

Sarah, a freelance writer, noticed her eyes straining after switching to a 27-inch iMac. The default 2560×1440 resolution made text appear tiny. According to Apple's 2023 Human Interface Guidelines, optimal readability requires at least 12pt font size at your chosen resolution.

  1. Click the Apple logo > System Settings > Displays
  2. Under Resolution, select Scaled
  3. Choose a higher resolution like 3008×1692 (more space) or 2048×1152 (larger text)
Pro Tip: Use Apple's Display Zoom for Retina-optimized scaling without pixelation.
