Considering an upgrade
Screen diagonals are 6.9″ and 6.1″. iPhone 18 Pro Max has the larger display, useful when space for spreadsheets, documents or multiple windows matters. This comparison covers the stated sizes; a different chassis size may change the conclusion.
Display refresh rates reach 120 and 60 Hz. iPhone 18 Pro Max supports the higher rate, relevant to scrolling and animations; it does not by itself guarantee that frame rate in games.
iPhone 13 is 75 g lighter (249 versus 174 g). That is a concrete advantage when carrying the device frequently, and usually matters less at a desk.
Specified maximum SDR brightness is 1000 and 800 nits, higher on iPhone 18 Pro Max. Consider this in bright ambient light. HDR brightness is a separate specification.
