Morphology

size + up

The MWE meaning 'to form a judgment' is an extended use of 'size' (to measure) with the particle 'up' adding a sense of completion or focus, so there is a transparent clue to evaluation. However, the specific evaluative/assessing sense of the phrasal verb is a metaphorical extension and particle meanings vary, so a B1 learner who only knows the literal constituents may not reliably infer the exact sense without prior exposure.

Etymology

Size up: The phrasal verb size up comes from the simple image of looking someone from head to toe to see their size, with your eyes moving up and down to get the full picture. That's why it now means 'to judge or form an opinion'.
