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.Quality and limitationsViewports wider than 6,000 CSS pixels or taller than 4,000 are excluded from published distributions. Historical DPR values are normalized to 0.05 steps. Device class is inferred locally and remains an approximation; legacy tablet classifications are excluded.Audit detailsRaw samples1,098Dimension anomalies12Legacy tablet samples124Aggregate updated2026-08-31Related toolsViewport Size CheckerSee your browser's CSS viewport size and window size live.
