What is the best size of box for packing books?

I am moving soon, and have lots of books, maybe one or two hundred. What would be the best size (approximate dimensions) of a box that can carry several books at once but not be too heavy? I want to avoid the risk of back injuries.

keep it around 12 x 9 x 9.

be sure you can close them, and stack them.

roll them out on a dolly. You'll be glad you did.

24 INCHES X 24 INCHES. A BOX THAT WILL CARRY JUST ENOUGH BOOKS WITHOUT BECOMING TOO HEAVY.

Books are heavy, pack them in small boxes, go to U haul or another box store and get the smallest size.

11 x 8 x 6

thats about the size i use to ship stuff on ebay.

Maybe a shoebox size. If you go for the file box sizes they can be formidable in the weight and the handles get blocked by books.

For moving-keep it reasonable-go with 12 x 12 x12 maybe 16 x 16 x 16 max-

What they call 40 pounders. That carry apples and other fruit. Check at the grocers and see what size that is. Also good place for boxes is the liquor stores, good and strong and about the same size.

I like to use a box that's used for storing legal papers. It even has handles. Also, if you can get a plastic milk crate, they're wonderful. They're a lot stronger than cardboard and have handles. The only downside is that they don't have lids but they stack incredibly well. And they are re-usable. Try and see if you can get some from your local grocery store. If you need extra boxes for moving, the grocery store is a good place to ask. They usually just crush them and will let you have them for free.
