The shape of the hole is fairly standard, the sizes you see listed are usually going to be the length, this way people can buy locks based on the thickness of their door or the location of the part of the cabinet that the lock will engage.
Here is a
PDF describing some locks available at Rockler, I am sure that the locks Peale has to offer are similar in style, as would be the ones at HD. I bet Peale's price is better than the others though, and you would be supporting a fellow "Arcadist."
If I didn't already expect to be making some purchases from other arcade sources that offer locks, I would hit Peale up for a couple myself.
