Enter the distance, length, and angle into the calculator to determine the angular size of a triangle.
Angular Size Formula
The following formula is used to calculate the angular size.
D = 2 * L * tan (a/2)
- Where D is the angular size
- L is the radius/length depicted below
- a is the angle depicted below
FAQ
What is an angular size?
An angular size is a value of length that represents the total length of a field of view from a point of a triangle, a certain radius, and certain angle. This can be seen as D in the above depiction.
