How many files fit in one inch of filing cabinet drawer space?

A useful rule of thumb for planning filing capacity: one linear inch of hanging folder drawer space holds approximately 50–80 sheets of paper (1/5-cut folders), or about 3–5 thin file folders. For heavier files (each 1/4 inch thick), one inch holds 3–4 folders. Knowing your typical file thickness lets you estimate total drawer capacity: a 27-inch-deep vertical cabinet drawer holds roughly 25 to 30 typical client files at comfortable density. For planning a whole office, tally up your current folder count, calculate linear inches needed, and divide by drawer depth to find how many drawers you require. Adding 20–30% buffer for growth is smart. FindOfficeFurniture.com — call 888-719-4960 to help size your filing system.
