Have you ever noticed that when you turn something on with a big motor the lights go dim for a second. That is this huge load gtbarsi is talking about and if that demand by the motor is not met by the generator it will take longer to start up and is harder on everything.
The other thing you need to decide on is what do you want to run if you are on the generator. The big users of electric are the oven (if electric), Do you want to be able to use the oven or will you just use the grill. Do you want to use the A/C (this puppy has one LARGE motor and surge). You need to look around the house and decide what you want and what you can live without. Anything that produces heat takes a lot of power (coffee pot, heat in house). NOTE: You can always plan to share power example - You can turn the A/C up when you cook dinner.
Trust me I lived 7 days in north Alabama without any power a couple of years ago when several tornados came thru the area. My generator was small and I had to play the management game but I keep the tank alive and food OK in the frig. It was the end of April so not much was needed for heat and we lived without A/C.
We are moving to Florida and yes a whole house generator is on my list (I don't want to do that again). I suggest looking around and thinking about what do you want an what can you live without. Then add up the wattage, on you have that think about how/when you want to use these devices and you'll have your requirements for the generator.
Also in some cases you may not be able to find the wattage on something so here is a formula for you
Wattage = voltage * current (in amps)
The voltage is 120 so if you have an A/C unit that pulls 30 amps you have 30 * 120 or 3600 watts.
Hope this helps
