What instant film should I use with Fuji PA-45?

I recently bought an Fuji PA45 instant holder from my Cambo. I bought 3 packs of Fuji FP-100 C Professional film only to find its way too small. Could someone point me towards the product I need please? I only intend to shoot B&W, my preference is that but colour is my only choice then that's what I get. Thanks in anticipation.

Hi,

FP-100C is made in two sizes. The smaller is more common but for your LF camera you'll want the 4x5 size. It's the same film (FP-100C) but the pack is marked as for 4x5.

All the best with it,
Hal
