Professional Design Tools

Calculate the exact track length, g-forces, and energy requirements for your roller coaster design using professional-grade engineering formulas.

Select Track Type

Standard Coaster

Loop-the-Loop

Spiral/Helix

ℹ️ The maximum height of your roller coaster’s main lift hill. Higher lifts provide more potential energy.
ℹ️ Higher complexity means more turns, banks, and elements which affects track length calculation.
ℹ️ The angle of the first main drop. Steeper angles create more acceleration and excitement.
ℹ️ Major elements include loops, corkscrews, zero-g rolls, etc. Each adds to total track length.
ℹ️ The distance between rails. Standard gauge is typically 1-1.2m for most roller coasters.
Please enter a valid track width between 0.5 and 2 meters.
ℹ️ The number of connected cars in your coaster train. Affects total mass for energy calculations.
Please enter a valid number between 1 and 20.
ℹ️ The type of landscape your coaster navigates affects design constraints and track length.

Advanced Physics Parameters

Fine-tune your design with detailed physics parameters to create a safe, thrilling coaster experience.

ℹ️ The maximum acceleration force riders will experience. Industry standard limits this to under 4g for comfort and safety.
ℹ️ Represents energy loss due to friction. Modern coasters use wheel bearings to minimize this value.
ℹ️ The smallest radius used in any vertical loop. Smaller radii create higher g-forces but more thrilling experiences.
ℹ️ The smallest radius used in any horizontal turn. Affects lateral g-forces and track length calculation.
ℹ️ The total mass of an empty train. Used to calculate energy requirements and forces.
ℹ️ The total number of riders per train. Used to calculate total loaded mass.
ℹ️ The average mass per passenger used in calculations. Industry standard is typically 75-85kg.
ℹ️ The initial speed of the train as it leaves the station. Typically 2-5 m/s for most coasters.
ℹ️ Different loop shapes provide different g-force experiences and require different calculations.
