agility ladders

Hey T-maggers, sorry if this has been covered before but i am looking to patch together an agility ladder untill i can anti up and buy one (untill about march next year i am still a poor uni student, with heaps of nephews and nieces to pick up christmas presents for). My question is what dimensions should i be going for? ie the box section should be ? inches by ? inches, with ideally how many ‘box’ sections???

Thanks guys…

sorry people i found the info on a previous thread… yeah yeah im a dumbass
