What size does the sheet of coroplast need to be to make a 2x4 c&c cage

i was going to order one online but its really expensive so if i can get to a sign shop what size does the sheet need to be (in inches if possible). as i said im planning on making a cage that is 2 grids by 4 grids

please only answer if u know what a c&c cage is!

I'm assuming that you have 14 inch grids like I do...that would make the diminsions of the grid 28 inches x 56 inches or 2ft 4 in x 4ft 8 in. and with a 6 inch lip on all sides that would be:

3 ft 4 inches x 5 ft 8 inches. you can round up to the highest and go 4 ft x 6 ft and trim it down.

My friend has the same exact diminsion cage. and that is what she ordered.
