Turning Radius Calculator [ Vehicle, Aircraft, Car, Trailer

Divide the wheelbase (WB) of the vehicle by the tangent of the steering angle (a) to calculate the turning radius (TR).

This calculation is essential for designing parking lots, roadways, or other spaces where vehicles navigate tight turns. It applies to cars, trucks, trailers, aircraft, and ships. By considering factors like wheelbase and steering angle, the calculator ensures safe and efficient turning capabilities, optimizing vehicle maneuverability and planning.

Formula:

TR = $WB / \tan(a)$

Variable	Description	Unit
TR	Turning radius	Feet (ft) or meters (m)
WB	Wheelbase	Feet (ft) or meters (m)
$a$	Steering angle	Degrees (°)
$\tan(a)$	Tangent of the steering angle	Unitless

Solved Calculations:

Example 1: Calculating Turning Radius for a Car with $WB = 2.5 \, \text{m}$ and $a = 35°$

Step	Value	Explanation
Wheelbase ( $WB$ )	2.5 m	Distance between front and rear axles
Steering angle ( $a$ )	35°	Steering angle in degrees
Formula: $TR = WB / \tan(a)$	$TR = 2.5 / \tan(35)$	Substitute values
Calculation	$TR = 2.5 / 0.7002$	Use a calculator for $\tan(35°)$
Result	$TR = 3.57 \, \text{m}$	The turning radius

Example 2: Calculating Turning Radius for a Truck with $WB = 4.5 \, \text{m}$ and $a = 25°$

Step	Value	Explanation
Wheelbase ( $WB$ )	4.5 m	Distance between front and rear axles
Steering angle ( $a$ )	25°	Steering angle in degrees
Formula: $TR = WB / \tan(a)$	$TR = 4.5 / \tan(25)$	Substitute values
Calculation	$TR = 4.5 / 0.4663$	Use a calculator for $\tan(25°)$
Result	$TR = 9.65 \, \text{m}$	The turning radius
