My First PCB, a few beginner questions.

You will have to position the headers vertically 0.7" apart yourself and looks like they are on-grid horizontally. Eagle has a ruler system to make this easier.

Thank you Ross. I think I did just that here: [http://i.imgur.com/a0t58tr.png](http://i.imgur.com/a0t58tr.png)

Do you know how I figure out what diameter those holes need to be though? I will use standard .1" pitch square headers. Those holes on the picture are spaced .1" apart, so pitch should be good.
