I have the TYST42PA20 with my PW6 (this is the same stand as for the PA20 model).
It is a funny shape and hard to measure accurately, but it is roughly 57cm wide, and at its widest point 33 cm deep. When the screen is mounted, the bottom of the screen is approx 6cm above the table.
a wall braket?
Any less deep and serios risk of topple there are some glass shelved panny floor stands but they would be as deep.
Why is the obvious question!
