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

Desk depth specification is driven by monitor count and ergonomic viewing distance. ANSI/HFES 100-2007 recommends a minimum 20" monitor viewing distance for typical office monitors — requiring a desktop depth of at least 28–30" when factoring in keyboard and wrist rest placement. At OfficeFurniture2go.com, our commercial L-desk main surfaces are 30" deep as standard, with 24" return depth options for space-constrained configurations.
