How do you calculate the number of elevators needed in a building?
The rule of thumb is one elevator for every 75 to 80 hotel rooms for hospitality. There should a minimum of one elevator for even two or three-story hotels. Add an additional elevator for four floors. The distance between the elevator and the most distant room should not be beyond 150 feet.
How is elevator capacity determined?
The larger the building, the more capacity it will normally have. In a mid-rise building, for instance, elevators can usually hold more like 3,000 or 4,000 lbs (1,361 – 1,814 kg), and in high-rise buildings, the limit is usually closer to 4,000 lbs.

How do you calculate the distance between stops in an elevator?
In other words, distance between the stops is 30 / 5 = 6 floors or 6 x 3 = 18 meters. This means that each round takes the elevator time to travel to the floors + time to open and close in each floor + time to fill up the elevator in ground + time for the elevator to come back to ground floor. Let’s calculate the number:
How long should elevator wait times be in a building?
