This is only true when the sprockets are the same size, and it's actually pitch multiples, so the multiple should be 3/8".
That gives you an integer number of links. (3/4" will work because it is a multiple of 3/8".)
http://www.rbracing-rsr.com/chainlength.html is a very simple calculator. Set the pitch to .375 and try different combinations of sprocket size and different lengths. You'll see that for a 1:1 sprocket ratio it's easy to get integer numbers of links (just put a multiple of .375 for your center distance). For any other ratio, you'll have to use a bit of finagling to get it a center distance that yields an integer number of links.
