Translate focal length and sensor size into angles of view, with optional framing size at a distance. Perfect for planning shots and understanding lens coverage.
Angle of view uses 2 · arctan(sensor dimension / (2 · focal length)). Scene size is calculated from the selected distance.
Scenario: Group photo planning with 35mm lens on full frame
Setup: Standing 5 meters from group
Coverage: ~5.1m wide × ~3.4m tall frame
Practical use: Can fit ~8-10 people in comfortable arrangement
The angular extent of the observable world captured by your camera and lens combination.
Smaller sensors capture a narrower field of view with the same focal length, making lenses appear more telephoto.
These correspond to the field of view in each direction. Diagonal is often quoted in specs as it's the largest value.
Enter your shooting distance to see exactly how much of the scene fits in your frame—useful for planning portraits, architecture, and group shots.
Very close to reality for most lenses. Some wide-angle and fisheye lenses may have slight variations due to optical design.
