Good question. Luckily, there is a simple formula to calculate the size of air conditioner that you need.
First of all, you need to understand that all air conditioners are rated in British Thermal Units (BTU). So you will need to know how many BTUs you need to cool your space.
To calculate how many BTUs that you need to cool your space, simply multiply the square footage of your area by 25 and that will give you the number for BTUs that you will require.
If you have a 12 by 15 foot bedroom, 12 X 15 that means your square footage is 180 square feet.
180 square feet multiplied by 25 is 4500 BTUs.
If you have the same 12 by 15 foot bedroom, plus a 15 X 30 foot living room to cool then... (12 X 15) + (15 X 30) means that your square footage is 180 plus 450 square feet for a total of 630 square feet.
Multiply this by 25 gives you a total of 15,750 BTUs..
Well this is where is get down to personal choice.
Many people like to have a thermostat and timer at a bare minimum. Some others feel that having WiFi connectivity is also important.
