Shadow Length Calculator
Calculate how long a shadow will be based on object height and sun elevation angle.
Idealized calculation without atmospheric refraction.
Examples
- Height 2 m, angle 45° ⇒ 2 m
- Height 1.5 m, angle 30° ⇒ 2.60 m
FAQ
What is sun angle?
The elevation of the sun above the horizon.
Can the angle be zero?
No, a zero angle would produce an infinite shadow.
Should angle be in degrees?
Yes, input angles in degrees.
Does this consider terrain?
No, it assumes flat ground.
Additional Information
- Shadows shorten as the sun climbs higher in the sky.
- Near sunrise or sunset, small angle changes produce large shadow variations.
