List who or what must pass through each opening: people, bins, garden equipment or vehicles. Measure the actual item and its turning path. A gate leaf width is not necessarily the clear opening, and neither is necessarily the center-to-center spacing between supporting posts.
Check the chosen gate kit for hinge and latch clearance, ground clearance and post reinforcement. Mark the swing arc on the sketch. Keep gates clear of slopes, steps, parked vehicles and public access routes. Sliding systems need room beside the opening and a suitable support arrangement.

↗A swing gate needs room for its arc and ground clearance across that arc. A sliding gate needs space alongside the opening, plus the required track or cantilever arrangement. Compare the clear usable opening rather than just leaf dimensions.
