A 9000 BTU mini split air conditioner can effectively cool an area of up to 350-400 square feet.
The recommended square footage for a room that requires a 9000 BTU air conditioner is around 350-400 square feet.
I would first make the decision as to how much square footage you except the air conditioner to cover. If it is a normal size square footage I would base your purchase on that.
Look in the metric handbook
To determine the appropriate air conditioner size for a room, you need to calculate the required capacity based on the room's square footage. The general rule is to have 20 BTUs (British Thermal Units) per square foot of space. To calculate the required capacity, multiply the square footage of the room by 20. For example, a room that is 300 square feet would need an air conditioner with a capacity of 6,000 BTUs.
You don't. Its cubinc footage, not square footage.
Air conditioner BTUs are recommended based on the square footage of a room. A room that is 20'x28'x15' high has a square footage of 560, as the height is not usually factored in. A room that is 560 square feet should have an AC with at least 18,000 BTUs. Because of your high ceiling, though, consider one with at least 20,000.

To determine the size of air conditioner you need for your room, measure the square footage of the room and use a sizing chart provided by the manufacturer. This will help you select an air conditioner that is the right capacity for your space.
The square footage of my house is 2,000 square feet.
In order to get the square footage you need to take 13' times 15' and you will get the square footage
