How to make a texture to match plane's size?

Questions & Answers
1

So, I am wondering, in order to have good textures in my 2d top down game, how can I make a sprite… say… in Paint.NET… match the size of a plan? Is there some sort of scale factor or something, or do you just have to do trial and error? I don’t feel like downloading an external program, for I am not a real graphics artist, just mostly a programmer / level designer.

Thanks for any help!

EDIT: I notice I was unclear, so let me explain this a bit better. I mean to make a picture (say 200 x 200), and then to create a plane that same size, so the picture isn’t super distorted and stretched out. So, it looks like the actual picture I made.

I got it working. On the mesh renderer, in Materials, Size was set to 2 instead of 1, and so there were two images on there making look all… ugly.
