How long and wide should my dirt bike jump be to do tricks on an 85cc?

[Carson]

I've been riding about a month now and I just made a track in my back yard about a half mile long, and I can do some basic tricks on my 15 foot table top like: Fender grab, fender kiss, whip, no hander, one hander, nothing, no footer, one footer, table whip, and seat grab. Im going to do some bigger tricks soon so I need your help.
