Calculate accurate dimensions for your skateboard ramp project. Set the height, transition radius, deck length, and other parameters to generate a technical drawing with precise measurements. Whether you're building a backyard quarter pipe, a mini ramp, or a flat bank, this free tool helps you plan your build with confidence.
You can design four types of ramps: quarter pipes, half pipes (mini ramps), flat banks, and spine ramps. Each type includes adjustable dimensions like height, transition radius, deck length, and flat bottom length. You can also toggle coping styles and view a skateboard on the ramp for scale.
Adjust the ramp dimensions using the controls and the tool generates an accurate technical drawing in real time. The geometry uses proper transition curves so the measurements reflect how a real ramp is built. Switch between imperial (feet and inches) and metric (centimeters) units.
Yes, completely free with no signup or account required. Design as many ramps as you want and share your designs via URL.
Depending on the ramp type, you can adjust ramp height, transition radius, deck length, platform height, flat bottom length, overall length, and angle. Lock specific dimensions and the calculator adjusts the others to maintain valid geometry. Space constraints let you set maximum height and length limits for your build area.
Every design is encoded in the URL, so you can bookmark it or share the link with anyone. The recipient sees your exact ramp configuration with all dimensions. Click the share button to copy the link.
