A standard bankers box is usually 12.5” wide by 15.5” deep, and 10.5” high and will hold about 2,000-3,000 pages. The exact amount of pages depends on the files stored, and how they are stored in the box. Envelopes, file folders, staples, notes, and other such items can take up space and thus the box will hold less. If a box was completely full of paper files only, then it would approach the 2,700-3,000 page capacity.
