Clear text should be comfortable to read at your normal viewing distance. Compare edges, spacing and punctuation without leaning closer between samples.
The size control uses CSS pixels, not a physical millimetre measurement. The sample includes characters such as I, l, 1, O and 0 so you can compare edge clarity and character separation. Font rendering, weight, spacing and contrast can change readability even when monitor resolution is unchanged. This is a user-controlled visual comparison rather than an automatic pass/fail result or a score for your eyesight.
Browser zoom, device pixel ratio, operating-system scaling, font smoothing and panel characteristics all influence the result. This page does not calibrate monitor sharpness, measure subpixel geometry or diagnose vision. A screenshot reproduces software-rendered text but cannot capture all physical display artifacts. Compare the same sample on another display with matching settings. Fullscreen is optional, and normal browser controls can exit it.
No. The controls use CSS pixels. Browser zoom, device pixel ratio and operating-system scaling affect how large they appear on the physical display.
