Belong or conform (3,2)

I think it could be either:

Which length description are you looking for?:

3,2

fit in

This clue is a double definition.

'belong' is the first definition.
(I've seen this before)

'conform' is the second definition.
(I've seen this in another clue)

(Other definitions for fit in that I've seen before include "Conform after adjustment" , "Belong" , "Be in harmony (with)" , "Find time for" , "Not be out of place" .)

I've seen this clue in The Mirror.
