How high should my zipline platform be?
How high should my zipline platform be? The longer your zip line, the more likely you'll need to start or end high enough to require a platform. If you're planning on building a platform, wait until you have the zip line up before you build it. Platforms for both starting and end points should be 5 feet below the height of the cable.
Do heavier people zipline faster?
Your body mass: the heavier you are, the faster you'll travel. Slope of the line: the steeper the line, the higher the velocity.
