What angle gives maximum range?

On flat ground, 45° gives maximum range for a given speed. With a ramp elevation, the optimum shifts slightly below 45°, so the best angle depends on both the launch and landing heights.

Does air resistance matter?

For cars at typical stunt speeds, drag reduces range by 10–30%. The drag factor option provides a rough correction, but it is still only an approximation.

What about vehicle rotation?

This calculator treats the vehicle as a point mass. In reality, vehicles rotate (pitch) during flight — stunt riders manage this with throttle and body position, which can change the actual landing behavior.

How is landing G-force estimated?

Landing G depends on suspension travel and deceleration time. The estimate assumes a 0.5 s deceleration — actual values depend on suspension setup and landing surface.

Can I use this for bicycles?

Yes — enter the bike speed and ramp angle. BMX and mountain bike jumps follow the same projectile physics, so the same equations apply.

Headwind reduces range; tailwind increases it. Add/subtract wind speed from launch speed as a rough approximation, especially if the wind is strong enough to matter.

About the Car Jump Distance Calculator

The **Car Jump Distance Calculator** computes the range, maximum height, hang time, impact speed, and impact angle for a vehicle (car, motorcycle, BMX, or any projectile) launched off a ramp. Enter the launch angle, speed, ramp height, and landing elevation, and the calculator applies projectile-motion physics to predict the full trajectory. It is meant for fast trajectory estimates, not for replacing a full stunt safety review. The output gives you a simple way to compare different ramp or speed choices before you move to a detailed setup review.

Whether you are a stunt coordinator planning a car jump, a motocross rider sizing a ramp, or a physics student solving a projectile problem, This calculator delivers the key trajectory outputs. The calculator treats the vehicle as a projectile under gravity (with an optional air-drag approximation) and accounts for elevation differences between launch and landing points.

Explore the presets for stunt ramps, BMX jumps, motocross, and rally scenarios, and use the angle-range table to find the optimum launch angle for maximum distance.

When This Page Helps

Use this calculator to estimate jump range, flight time, and landing speed before comparing ramp angle, takeoff speed, or landing elevation changes. It helps you see how sensitive the jump is to speed and geometry before you commit to a setup. That makes it a useful planning check before any real-world stunt or bike-ramp decision.

How to Use the Inputs

Select a preset or enter the launch angle in degrees.
Enter the launch speed in km/h, mph, or m/s.
Set the ramp height above ground.
Set the landing height (0 for flat ground, negative for lower landing).
Optionally add a drag factor for air resistance.
Read jump distance, max height, hang time, impact speed, and impact angle.

Formula used

Range: R = vx × t_flight
Time of flight: t = (vy + √(vy² + 2gΔh)) / g
Max Height: H = h₀ + vy²/(2g)
Impact Speed: v = √(vx² + (vy − gt)²)
Impact Angle: arctan(|vy_impact|/vx)

where vx = v₀ cos θ, vy = v₀ sin θ, Δh = h_ramp − h_landing.

Example Calculation

Result: Jump distance ≈ 44 m, max height ≈ 6.1 m, hang time ≈ 2.6 s

A car launching at 80 km/h (22.2 m/s) off a 30° ramp at 1.5 m height clears about 44 m, reaching a peak of 6.1 m, and is airborne for 2.6 seconds.

Tips & Best Practices

Maximum range on flat ground is at 45°; with ramp elevation, aim slightly lower.
Impact speed always exceeds launch speed when landing below the ramp.
Doubling speed quadruples the range (range ∝ v²).
A steeper angle gives more height but less distance — useful for clearing obstacles.
Real stunt ramps are typically 15–30° for safety and landing angle.

What The Model Assumes

This is a projectile-motion estimate. The vehicle is treated as a point mass launched with a known speed and angle, then acted on mainly by gravity. That is good for first-pass trajectory work, but it leaves out suspension dynamics, pitch rotation, tire interaction, and detailed aerodynamics.

Why Landing Height Matters

A lower landing area increases flight time and usually extends range, while a higher landing area shortens the jump and raises the risk of coming up short. That is why terrain profile matters as much as launch speed in real jump planning.

Practical Limits

The numbers are useful for comparison and screening, not for stunt approval or safety signoff. Real jump setup depends on rotation control, ramp geometry, vehicle setup, and landing-surface design as much as on pure range.
