Tarp size for cold frame/hoophouse?

[Endur]

I have been frustrated all day, trying to figure out what size tarp I will need, without ordering one that would be overkill.

Its 10ft(W) X 20ft(L) 8ft(H) Hoop House style

I will need an extra 3ft on either side of the width and 4ft on the length....

I would appreciate if anyone could help/show me, how to calculate the dimensions ill need for my hoop.

Much Appreciated

If it's a 20"ft pvc rig then 24 ft wide will be adequate. length will be 20+8+8+ whatever excess you want on each end, id say 6 total ft extra so 38ft long is more than enough.

Like z-ro suggested.........I use 20ft sch 40 pvc pipe for each hoop on the cheap hoopas and use 4ft spacing instead of 6ft, and normal length of 48ft, so I order up a 32W x 72L, as its 20ft of pipe no matter how its placed with extra for secure fastening to wiggle wire, and length I figure my overall height and x2 that and add 48ft give or take a few ft, I may end up with extra but try ordering wrong size that's too small and than fork out for another that fits but took another 3 weeks to ship out, its not good I know from my own adventures.
And most places that have covers should be able to help with dimensionals, well, if they are any good they will and would.

Another idea endur is to take a tape measure and measure the total distance of the hoop from the ground on one side to the other and then add 3 ft for each side , do the same for the length of the hoop house and you should have the measurements you need, I'm sure you'll get it figured out one way or another
