They are all PE woven cloth, the same material.

The size of 12*20 tarpaulin is: 3.66*6.09m, which is slightly larger when used on a 10*20 frame. The size of 13*20 tarpaulin is: 4*6.09m, which is much larger than the frame. You still have to choose the appropriate size according to your frame.

the sides are seperate from the roof panel so, yes

yes the sides come seperately

Check Vevor’s web site, they might have your size.

It’s not heavy duty but it does the trick the sunlight dries it up and it becomes brittle after a year or so . But the replacement is cheap under $40

It did for me.

It does but honestly there's two sizes take a little better look at the description and as long as your outer poles to the peak which is the center of the thing or the same it will fit
