Hi I have been skateboarding for about 4 months now and so far I'm loving it. I have decided to do a father son project over the school holidays and plan on finishing it before the end of the school holidays. The custom Mini ramp template seemed to be the best plan for my backyard, so I can pack it up in to 3 parts and put it away when not used.

The only problem is that with the space my father will let me use length-wise I can not fit it. The length of the custom mini ramp requires 24 feet which is 7.3 meters. The maximum amount of length i can use in my backyard is approximately 5 meters, which is 16.4 feet. Width-wise i can fit it fine. Personally I think 5 meters is more than enough length for a 3-3 and a half or so feet in height ramp.
Any help in plans and measurements would be helpful, thanks!
