How to Use This Calculator

Enter Release speed, Release angle, and Release height.
Set Shot mass, Sector angle, and Max expected throw.
Review the Throw Distance (m) result.
Use Optimal Release Angle (°) and Max Distance (optimal angle) to inform your decision.

How the result changes with Release speed

Release speed: Speed of shot at release (elite men ~13-14 m/s).
Release angle: Angle above horizontal (optimal typically 37-42°).
Release height: Height of shot at release (depends on athlete height and technique).
Shot mass: Shot mass: men 7.26 kg, women 4.0 kg, various for youth.
Sector angle: Landing sector angle (IAAF standard: 34.92°).
Max expected throw: Maximum expected throw distance for field layout planning.

Throw Distance: Predicted throw distance from the front of the circle.
Optimal Release Angle: Best release angle for max distance at this release height.
Max Distance (optimal angle): Distance at optimal angle with same speed.
Distance Lost to Angle: Distance lost from non-optimal release angle.
Flight Time: Time the shot is airborne.
Maximum Height: Peak height of the shot trajectory.
Landing Speed: Speed of shot at impact with ground.
Landing Angle: Angle of descent at landing.
Release Force: Estimated force applied during the putting action.
Average Power: Average power output during the release phase.
Sector Width at Max Distance: Width of the landing sector at the maximum expected throw distance.
Sector Line Length Needed: Length of sector boundary lines needed for field layout.
Circle Diameter: Official throwing circle diameter.

Identify Input Parameters
4 parameters
Release speed = 12, Release angle = 38, Release height = 2.1, Shot mass = 7.26 = 6 input(s) provided
Calculate Throw Distance
Throw Distance = vx * tFlight
16.56 = 16.56
Calculate Optimal Release Angle
Optimal Release Angle = (optimalAngleRad * 180) / π
41.4 = 41.4
Calculate Max Distance
Max Distance = vxOpt * tFlightOpt
16.65 = 16.65
