Size of coroplast needed for 2x4 C&C cage with loft?

[MWpiggies]

Hi, I'm going to be building a C&C cage soon, and wanted to know the measurements for a piece of coroplast for a 2x4 cage with a 2x1 loft with ramp. I found that most places with coroplast are in the US, does anyone know where I can get reasonably priced coroplast in Canada?
thanks!
