The whole (3)

I think it could be either:

Which length description are you looking for?:

4,2,3

all

'the whole' is the definition.
(all of something)

This is the entire clue.

(Other definitions for all that I've seen before include "Everything or everyone" , "and 16 Across and 23 Across: Even so" , "Straight garden path" , "100%" , "Avenue, walk or garden path" .)

I've seen this clue in The Sun.
