How do I estimate the total weight of a fully loaded filing cabinet?

A typical 4-drawer commercial vertical filing cabinet weighs 90–120 lbs empty. Each fully loaded drawer adds roughly 40–50 lbs (at manufacturer weight ratings), meaning a full 4-drawer cabinet could reach 250–320 lbs total. For floor loading purposes: concentrated on four small feet, a loaded 4-drawer cabinet may exert 15–25 PSI pressure on the floor — well within standard commercial office floor capacity (typically 50+ PSF live load). Older buildings or mezzanine storage areas may need a structural check for concentrated loads, especially for a full row of heavily loaded cabinets. Moving loaded cabinets on casters distributes weight across more points. When planning a large file room, consult a structural engineer if floor capacity is uncertain.
