Projectile Range Calculator
Calculate the horizontal range of a projectile launched from level ground given its initial speed and launch angle (R = v² × sin 2θ / g).
Formula: R = v² × sin(2θ) / g
About Projectile Range Calculator
Projectile Range Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate the horizontal range of a projectile launched from level ground given its initial speed and launch angle (R = v² × sin 2θ / g).
The calculation uses the standard formula R = v² × sin(2θ) / g and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
For a given launch speed the maximum range on level ground is achieved at a 45° launch angle, ignoring air resistance.
