Trebuchet Size Calculator

Note that your browser must be capable of running Javascript,
and that you must have scripting enabled to use this calculator

Please note that this is applicable to hinged counter weight and fixed counter weight trebuchets only.

Note that this is a very simple calculator meant to take the pain out of the maths involved in determining how big a frame to build for a desired range and efficiency.

It doesn't take in to account things like the mass of the throwing arm, or how the user is going to achieve the desired efficiency.

For a more complete calculator, Donald B Siano's site would be a much better place to visit
