Eagle part creation question

Community PCB Design
1

Hi,

This might be a dumb question, but here is goes: when I create a new through-hole part in Eagle, how much (if any) larger should I make the hole than the part data sheet specifies? I.e. I have a part that specifies 1.50+/- 0.1 mm holes, how big should I make the hole? And, does it even matter, given the board house probably rounds up?

Thanks!

Most PCB suppliers specify “finished” hole sizes, which includes the plating. You need to check, though.
