Field of View Measurement Tool

Measure your visible FOV and binocular overlap in simple guided steps directly in the browser, and help us expand our database of crowdsourced, realistic user-measured FOV data for each headset for the VR Headset Picker.
No controller required. This tool works both on PCVR and also fully standalone in the browser of headsets like the Meta Quest.

Current marker angle: --

In headset intro, use the white forward line and align it with world targets: RIGHT green target = YES, LEFT red target = NO.

To begin, perform 3 quick YES looks in intro. Then tracking locks for precise FOV alignment and the app measures LEFT eye first, then RIGHT eye.

Movement is quantized: tap for 1 deg, hold direction for 1s to auto-step continuously in 1 deg increments.

Desktop fallback: arrow keys move, Space/Enter confirms, Backspace goes back.
