How wide are lateral file cabinets, and which width should I get?

Lateral file cabinets come in three standard widths: 30", 36", and 42". The 36" is the most popular because it balances capacity and footprint — it holds about 30% more than a 30" but doesn't dominate the room. If you're putting the cabinet behind a desk as a credenza, measure your desk width first and match it. 42" laterals are great for high-volume filing rooms where you need maximum drawer capacity.
