This calculator will help you estimate the size
house you need, in square feet, based on types
of rooms, number of rooms, and room sizes you
want. This will then allow you to focus on the
floor plans that offer that amount of space.
When deciding on room sizes for your new home,
base your sizes on similar rooms in your current
home — and adjust up or down for your new-home
needs. To measure room area (square feet), multiply
room length by width. If the room is not perfectly
rectangular, treat it as separate rectangular
boxes, added together to get total area.
