i've been using them for a while. mine is standard letter size and holds 4 - 6 packs loosely. 12" x 18" and 10 5/8" height. another cabinet has 11" height.
none of my 22 oz bottles fit, but i have a 20 oz one that does.and i store EZ-caps in there, too. i sometimes put in blocks of foam to keep them from rattling around and tipping over.
(how did all these traditional bottle sizes come about anyway?)
