GoKawiilWeb dataset shows real 1080p browser viewports average just 920px tall
A newly published Show HN project analyzed roughly 1,000 real browser viewport measurements and found that displays marketed as 1080p typically render usable browser content at around 920 pixels of height, once toolbars, address bars, and OS chrome are accounted for. The dataset organizes results by device environment, withholding rankings until each category collects enough samples, and separates out anomalies and legacy tablet data to keep results accurate.
GoKawiil's interpretation of the reporting above, not reported fact.
Developers commonly design layouts assuming a full 1080px canvas, but this data suggests that assumption overstates real available space by roughly 15%, which can push critical UI elements below the fold. The careful handling of anomalies and misclassified devices (like touch-enabled desktops) also highlights how messy real-world browser telemetry can be, and why raw analytics often mislead design decisions.
- Actual usable browser height on 1080p screens averages about 920px, not 1080px.
- Data is organized by environment and hidden until a minimum sample threshold is met to ensure reliability.
- Touch-enabled desktops and dimension outliers are filtered from rankings but kept for auditing purposes.
