Sure there are JEDEC standards etc. I just suggest checking. ;-)
DIPs vary in length too.

Go to TI's web page, find the device, it will have "product folder" with
all the available packages and how they come (reel or whatever). Usually
if you click on the package code you'll get to a drawing of the package.
They are often left off the data sheets these days.

Of course once you have the package dimensions, you'll probably want to
come up with the *footprint*, so have a look at http://www.ipc.org
