Ever bought a piece of furniture that didn't fit in your home or even up your stairs? A mere inch can make that difference so precise planning is important. It is always important you've got a floor plan before you move. It makes the move more efficient, less stressful and less spontaneous. It also avoids any future back-aches on larger furniture. Measuring your home dimensions isn't the sole factor, many forget to consider their stairways, elevators, door entries (whether it's a bedroom or the main entrance, the two can sometimes differ), windows and even the height to your ceiling for chandeliers and ceiling lights.
