Show HN: 1080p is 920px tall – 1k real browser viewports
Anonymous aggregate viewport measurements from ScreenSize.net browser sessions, with sample size, quality exclusions and methodology shown alongside the results.
These observations describe qualified ScreenSize.net sessions during the reporting period. They are not global device or browser market-share estimates.
The most common desktop viewport is 1920 × 920 CSS pixels, representing 15.7% of 648 snapshot samples shown.
The most common mobile viewport width is 400px, representing 64.1% of 103 snapshot samples shown.
The most common device pixel ratio bucket is 1.00×, representing 64.6% of 751 snapshot samples shown.
Each environment is evaluated independently. Rankings stay hidden until that environment reaches the minimum display sample.
Legacy tablet samples are excluded because the first classifier could mistake touch-enabled desktop computers for tablets.
Clear dimension anomalies are excluded from rankings but remain in aggregate storage for auditing.
The report describes this site's measured browser sessions, not global device or browser market share.
A browser tab contributes at most one sample during its session. Measurements are rounded into monthly aggregate buckets. No IP addresses, user IDs, precise timestamps or full user-agent strings are stored. Global Privacy Control and Do Not Track signals are honored.
