I am in the process of designing some new prototyping boards and I wanted to find a standard pcb size. The only thing I could find from the almighty google was the set of Sick of Beige PCB sizes. It is simply amazing what people can come up with when they want to give away knowledge for free.
Here is a image of all of the standard PCB sizes:
If you use Eagle PCB editor then you can download a library from dangerousprototypes.com and start using them.
If you use Altium then you are out of luck. You have to make your own.
Since the information is free, I decided to start making some board outlines in Altium.
