What size generator to run a table saw?
Table saw draws about 1,800W while running and surges to 4,500W on startup. Allowing 20% headroom, size for at least 5,400W of starting capacity.
The surge is the number that matters. A generator rated to 1,800W will stall the moment the motor kicks in, because for a fraction of a second it needs 4,500W. Manufacturers advertise running watts, which is why people routinely buy one size too small.

Running more than one thing
Most people are not powering one appliance. Add everything you need at once and the calculator works out the real peak — your total running load plus the single largest surge, not the sum of every surge.
