ABow-front desks come in three common widths: 60 inches (24-inch side depth, 28–30 inch center depth, 4–6 inch bow projection), 66 inches (24–30 inch side depth, 28–34 inch center depth), and 72 inches (30-inch side depth, 34–36 inch center depth, 5–6 inch projection). Standard fixed heights run 28.5–30 inches; height-adjustable bow-front models are available in some product lines with ranges of 24–34 inches. The nominal depth in catalogs is always the side depth — always account for the center bow projection when measuring room clearance, as the desk extends further into the room at center than the catalog number suggests.
