Font Subpixel Rendering & Display Clarity Audit | Labs
Deep dive into how your OS and monitor handle font smoothing and subpixel rendering. Analyze RGB aliasing patterns.
Font Subpixel Audit
Analyze display subpixel rendering and text clarity.
Rendering Source
2D Canvas / No AlphaHover over the text to see the subpixel structure on the right.
Pixel Audit (10x Zoom)
RGB Smoothing
Most OS use RGB subpixel rendering to trick your eyes into seeing higher resolution. You should see red and blue fringes on the edges of black text.
Grayscale AA
If you only see shades of gray in the zoom, your system is using simple grayscale antialiasing (common on macOS or mobile).
Stem Consistency
Look for "hinting" artifacts where vertical stems might be forced to align to pixel boundaries for sharpness.
Why Audit Font Rendering?
Modern displays use different subpixel arrangements (RGB, BGR, Pentile). Using the wrong rendering algorithm in your OS settings (like ClearType on Windows) can cause "color fringing" or make text appear blurry.
