I have a 20.5 CF and a 14 CF and they are both almost full . I had to buy a second freezer last Nov when I killed my elk because the big one had wild boar and deer meat in it in addition to domestic meat. and vegetables. Do yourself a favor and get an upright, you will be glad you did and so will your wife and kids. My wife is 5 feet 2 inches tall and she almost had to stand on her head to get things out of the freezer at close to the bottom, she hated that chest freezer, our first was a chest ant it was a PIA trying to find things. Only reason I had it was because it was free to I put up with it until it crapped out, then I went to upright. Today they are all frost free no matter what size.
