Height of sculpture is about right (7)
I believe the answer is:
stature
'height' is the definition.
(I know that height can be written as stature)
'sculpture is about right' is the wordplay.
I cannot quite see how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is located in the answer.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for stature that I've seen before include "Height, calibre" , "Natural standing height" , "Consequence" , "Height; importance" , "Body height or high reputation" .)
