Camera Field of View Calculator
From focal length, shooting distance, and sensor size, calculate the real area captured in your photo (width x height) and the angle of view. Great for planning group and product shots.
Input
Calculate the real-world area captured in frame (width x height) and the angle of view from your lens focal length, subject distance, and sensor size. Handy for planning group-photo and product-shot compositions.

How it works
- The captured area is found from "sensor dimension x shooting distance / focal length". For example, a full-frame sensor (36mm wide) with a 50mm lens at 3m gives a width of 36 x 3 / 50 = 2.16m.
- The angle of view is calculated as theta = 2 x atan(sensor dimension / (2 x focal length)), shown separately for horizontal and vertical.
- With the same lens, a larger sensor captures more, while a longer focal length captures less. Moving closer to the subject also shrinks the captured area.
- This calculation is a guideline based on the thin-lens approximation. It is accurate for general shooting where the distance is much larger than the focal length, but may differ from reality in macro range or with special lenses.
- Sensor sizes use each manufacturer's representative nominal values. Results may vary slightly if your specific camera has different dimensions.
