My height = "Το ύψος μου"?
do people use this for height?
This seems odd. In English, we generally use length for babies (who can neither stand nor speak).
I cannot think of a context in which this makes sense in English ...
In my 70 years, I've never heard another native English speaker say, "My length is six feet." (And I've never said it, either.)
Neither have I and I never plan to. Whatever was intended here didn't work and will be deleted.
