How do I calculate the linear filing inches of a lateral file cabinet?

Linear filing inches (LFI) measures total file capacity — each drawer in a side-to-side configured lateral cabinet provides filing space equal to its width. A 36" wide 4-drawer lateral provides 4 × 36" = 144 linear inches of filing. A 42" wide 5-drawer unit provides 5 × 42" = 210 linear inches. A standard file box holds roughly 12 LFI of paper, so 210 LFI holds approximately 17–18 boxes worth of documents.
