3D Size of 2d input image and 3d shape size

I've been trying to discover the relationship of the 2d image size and 3d shape size. 3d cylinder works out to width = circumference and height the same, for some cases. This breaks down at some point and there seems to be no relationship. Can anyone shed some light on this. I am trying to project a pattern onto the 3d surface and work it backwards to cut out a 2d pattern to lay on an actual cylinder (I don't have cad).

Thanks

Thanks
 
There may be an exact way to find out but I don't think it's really necessary, unless I am misunderstanding you.

If you open the texture for the cylinder surface, you can make a label (for instance) any size you like within the boundaries of the texture layer. Save it. Look at the result, if it's not what you want simply edit it again to resize it.

Thanks for the reply but here's the problem. No matter what the size of my 2d input image Photoshop produces a 3d cylinder of an unpredictable (as far as I can tell) size. Usually in about a .6 to .7:1 ratio of diameter to height. My input image is 2"wx55h" and I get a cylinder about 28" in diameter and 42" high. It also appears the 55" image is compressed into the 42" height.

I'm probably going to say "duh" when I find out why but any suggestions are welcome.
Thanks
