Because of how small computer monitors’ bases have become, some compact office furniture, secretary desks, and corner desks can now fit a large computer monitor. However, this largely depends on the shape of the monitor’s stand, the shape and size of the desk, and the user’s desired setup.
Secretary desks are usually at least 30” wide and 24” deep to have enough space for writing. This may be enough space for a large monitor and keyboard or laptop.
Fitting both a laptop and a large computer monitor onto the top of the desk will be a challenge unless you put the monitor on the very top shelf above the main writing surface. You may find a small desktop computer to be a better option if you can tuck it into one of the lower shelves below the desk’s writing surface.
