What's the ideal depth for a home office desk?

The ideal home office desk depth falls between 24 and 30 inches, with 30 inches being the most versatile for a standard dual-monitor setup.

A 24-inch-deep desk works well for a laptop or a single smaller monitor, but at that depth a 27-inch screen sits uncomfortably close to eye level. Bump to 30 inches and a full dual-monitor arrangement fits without strain, leaving a usable front zone for a keyboard, mouse, and notepad. Desks deeper than 30 inches add surface area but require a longer arm reach for anything pushed toward the back.

Minimum practical home office desk depth: 24 inches, suited for laptop or single-monitor use.
Most common recommended desk depth for dual monitors: 30 inches.
Ergonomic guidelines suggest monitor distance of 20–28 inches from eyes, which a 30-inch desk accommodates naturally.
Desks exceeding 36 inches deep are typically reserved for drafting or specialty workstation use.
