What is the optimal desk depth for an L-shaped desk?

The sweet spot for L-shaped desk depth is 30" — this gives you about 18"–20" of clear space between your monitor and your body's position, which aligns with ergonomic guidelines for screen distance. Deeper 36" desks are great for architects or designers who need large-format surface space but can make reaching items at the back edge uncomfortable for average-height users. A 24" depth is a minimum and works if you're using a monitor arm that puts the screen at the right distance regardless of desk depth.
