To estimate the weight of your household, multiply each room with furniture by 1500 pounds. This includes bedrooms, living rooms, kitchens, playrooms, as well as basements, attics, and garages if they have furniture too. Following this rule, a 4-room house has an estimated weight of 6000 pounds. Remember, though, that this is just an estimate. Professional movers have their own equipment, combined with experience, to reach a more accurate number.
