I don't have the exact measurements as they are in the basement but if you really need them I can run down and measure them for you, but the sweater boxes I believe are somewhere around 11 lts. and the blankets are around 28 or 29 lts. Can't remember exactly. They are made by rubbermaid. I also have higher blanket boxes that have more arboreal area thant the 28-29 lts but a little less floor space. I use those for my bps and the long blankes for my corns. Hope that helps. Like I said I can measure them exact if you want, just don't have time to do it right now.
edit. Sorry I put 38 instead of 28 leters. lol
