eagle cad gride size question?

[9Lives]

After reading and experimenting and beating my head against the wall I finally have a layout I'm somewhat satisfied with for etching. I'm going to attempt to post pics later for some feedback. It's a simple version of the harmonic percolator. What I'm wondering is if there is a general grid size ya'll use for making sure the transfer comes out the corrct size with out tampering with it. I see in the GM tutorial he sets it to grid mil 50 2. Does that pretty much keep it the right size once I export the file? Hope this makes since.

I just go to Export and then print right out of eagle most of the time.

If I'm making it a project for others you'd need to take accurate measurements when in eagle and resize it to that size in another processing program.

The grid size has nothing to do with exporting.

Ok so once I do the whole board song and dance, export it and it's pretty much already size/scaled? It looked a little off to me but it seemed like an optical illution .
