Air Conditioners were invented in 1902. Willis Haviland Carrier invented them. As time went on, the usage of air conditioners increased. Nowadays, air conditioners come in different sizes and shapes. In recent times, almost every household has an air conditioner which is why it’s important to have air conditioners in different sizes as not all rooms are the same size.
The size of your room determines the size of your air conditioner. So, if your room is 24×24, you will need an air conditioner which is strong enough to cool a room that size. If your room is smaller than 24×24, then you will need a smaller air conditioner.
So we can pretty much say that the size and power of your air conditioner depends on the size of the room you are installing your air conditioner in.
What Air Conditioner is the Perfect Size For 12×12 room ?
The rooms in our houses come in different sizes. Air Conditioners come in different sizes as well. So, we need oversized air conditioners for giant rooms, and for small rooms, we need small air conditioners.
The cooling capacity is measured in BTU/hr. The cooling capacity denotes the size of your air conditioner.
If you wish to cool down a 200 square foot room, a 4000 BTU air conditioner is the best option. However, the problem jumps up when the room is as tiny as 12×12. Therefore, the best option for a small room is an 800 BTU portable air conditioner or a 5000 BTU window air conditioner.
By buying either one of these air conditioners, you can easily save space and cool your room without any hassle. However, a pro tip is always to buy a little bigger AC unit than this recommendation.

What Size Room Can A 6000 BTU Air Conditioner Cool?
Air Conditioners come in different shapes and sizes. There are air conditioners for every size room. Air Conditioners need 20 Btu for each square foot of living space. However, other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power.
A 600 BTU air conditioner can cool a 100 to 300 square feet room without a hassle; however, if the room is more significant, you will need a more oversized air conditioner as a 6000 BTU air conditioner cannot cool a bigger room.

Selecting The Perfect Air Conditioner For Your Space
When choosing an air conditioner, size plays a significant role. If you buy an air conditioner too big for your room, it will cool your room quickly, but it will also cost you more. In the same fashion, if you buy an air conditioner that’s too small, it won’t cool your room correctly.
So, we can easily say picking the perfect air conditioner is more about the size than anything else. The best way to select an air conditioner that’s the perfect size for your room is by knowing all the calculations and methods.
The formula used to calculate the square footage of a square or rectangular room will be the formula used for most rooms. This formula is given below:
L x B = Square footage
- Measuring A Square Room
Measuring a square room is very simple. For example, suppose the room you want to measure is 14 feet long and 12 feet wide. So. in that case, the formula would be:
14ft × 12ft = 168 square foot
- Measuring a triangle-shaped room
Measuring a triangle-shaped room is a bit different from measuring a square room. Therefore, the formula for triangle rooms is different as well. The formula for triangle room is :
L x B × ½ = Square foot
So, suppose the room you like is 13 feet long and 16feet expansive. Then the formula would look something like
13 foot x 16 foot × ½ = 104 square foot.
- Measuring an odd-shaped room is probably the most difficult one. To measure an odd-shaped room, you have to measure every part individually.
- The first step of measuring an odd-shaped room is to measure every wall and map that out.
- After the first step, we’ll break this room into smaller pieces and calculate the square footage of each of those pieces.
- We will calculate the area “A” first. Calculating this section is quite simple.
- While calculating “B,” we will use the same formula.
- The formula for C is similar; however, it requires us to half our calculation of L x B.
So after taking all these steps, we finally assembled them. The formula should look like
Area “A” + Area “B” + Area “C” = Total Square Footage
So, By figuring out the shape of the room, we can easily use the formulas mentioned before to find out the size of our room and buy the perfect air conditioner. Following these steps will help you vastly.

Things To Keep In Mind To Determine The Most Accurate BTU Estimate
We need to keep in mind certain factors if we want to get the most accurate BTU. One of the most common mistakes while purchasing an air conditioning unit is not considering the most accurate BTU. To get the most accurate BTU, we need to keep a few things in mind. Things to consider to determine the most accurate BTU estimate is given below:
- Sunlight: sunlight plays a huge role in determining the most accurate BTU estimate. If your room or space is sunny during the day, you have to increase your BTUs by 10 percent.
- Ceiling height: If your ceiling is higher than 8 feet, you will have to increase your BTU’S.
- Shade: if your room is in the shaded corner of the house, you need to decrease your BTUs by 10 percent.
- The number of people in the room: If more than two people are residing in the same room, then you should add 600 BTUs of cooling power for each person.
- Kitchen: If you install the air conditioner in your kitchen, you have to increase your BTU level by 4000.
If you pay close attention to all of the points given before, you can get the perfect size air conditioner for your space. In addition, if you follow these cautionary points, you can avoid making the common mistake of purchasing an under or over-powered air conditioning unit.
