Dear Snowball, I would suggest that you plan on just under what the Manufacterer says. For example we, bought the 60lbs ones ( medium I think), and we added approximately 50 lbs, and the food is right up to the opening. ( altho there is airspace above that.)
Unless you put them on their backs -- then you could fill them higher...but won't be able to stack them.
