Text Sharpness Test
Renders 8pt, 9pt, and 10pt text in black-on-white, white-on-black, and color combinations so you can judge subpixel sharpness on your panel. Fringed or rainbow edges on strokes point to subpixel layout issues — a common concern on OLED and some WQHD monitors used for coding and reading.
What you can use it for
- Decide if a monitor is sharp enough for coding
- Compare text clarity between OLED and IPS panels
- Check ClearType and macOS font rendering on external displays
- Spot color fringing on small text
How it works
- 1. Customize. Open the Customize panel to set text, colors, theme, and animation speed to your liking.
- 2. Go fullscreen. Click Fullscreen for an immersive, distraction-free display on any screen.
- 3. Done. No login, no install, nothing to download — it runs instantly in your browser and your settings are remembered.
Frequently asked questions
Why does text look fuzzy on my monitor?+
It can be low resolution for the screen size, non-native scaling, subpixel layout (especially OLED), or aggressive font smoothing. This test lets you compare sizes and color combos side by side.
Which sample is most revealing?+
Small black-on-white text at 8–9pt is the hardest test for reading clarity. Color combos reveal fringing on individual subpixel channels.
