There are so many variables like floor plan, insulation, and the outside air temp that the ratings for heating square footage don't mean anything.
I suggest you get an airtight stove that is too big for your needs normally. If you have a stove that is too big, you can build a smaller fire in it. Put in less wood and shut down the air so it doesn't all go up at once. When you need the heat, put in more wood and open the damper to get more heat. For overnight you can fill the firebox and adjust the damper so the stove puts out enough heat and lasts all night long.
The recent cold snap should give you an idea of the worst conditions that can happen in your area.
I bought the biggest stove I could find (3.5 cubic feet firebox) and put it in my old, not well insulated, mobile home. It is doing a good job. When we had the -40 overnight I loaded the firebox with split and cured oak and opened the damper some. It heated the house fairly well and lasted more than all night. You can't ask for more.
