What would be be a better texture size?

Question

Would it be better to have one 4096x4096 texture or four 1024x1024 texture? since in the end they are the same amount of data would they be the same, or would 4096 be better because it consists of less files? I'm new to texturing and this has been bugging me like crazy.

4096x4096. It helps Unity optimize draw calls. Unity can only batch together draw calls for meshes that share the same materials. Here are some reference links:
