It really depends on what you're using the bench _for_. The wrist rule
likely derives from the ideal height for planing lumber. I have both
a traditional height woodworking bench with face and tail vise, and two taller
(40")[*] benches for general assembly, electronics, tool boxes and a disk sander.

For non-woodworking tasks, I'd recommend higher, closer to the
eyes for detail work without bending over.

[*] for someone 195 cm, adjust as appropriate for end-user.

195 cm = 76.8"

40 / 76.8 = 0.52

0.52 * 61" = 31.7"

That's 4.7" higher than her wrists and certainly seems more reasonable than a 27"
workbench.
