It is 4 1/2 long and 2 3/4 round ( tapers to 2 1/2)
The 2 spouts are there for a couple reasons . 2 spouts allow it to pour better from the end spout .
I've never liked the look of one with a spout on the outside curve , that would hang in the down position when carried .
As for leaking , I tested the heck out of it with various leather gaskets . The 2 that are there work perfect .
The way it hangs will allow you to fill it from the top as it hangs .
Not sayin it's the right way , but it does work .
Thanks , Steve
