    Understanding how to measure accurately during a move is vital for making cost-effective use of packing boxes, storage facilities or hired freight haulers. Learning how to measure in linear feet and knowing the difference between a linear foot, a square foot and a cubic foot can help you use your shipping space more efficiently when moving to a new home.

    Why linear feet are important

    Measuring in linear feet is ideal for calculating how much space you’ll need in a moving container, moving truck or freight hauler. A linear foot refers to 12 inches in a straight line and is a one-dimensional measurement equivalent to a standard foot.

    A linear foot is 12 inches in a straight line.

    While it may also be important to know your rough cubic volume or weight, the majority of trucking services base their quotes on linear feet. Since most freight haulers can transport goods for more than one customer in a single trailer, they need an accurate estimate of how much floor space your belongings will take up.

    How to measure in linear feet

    The best way to measure in linear feet is with a ruler or measuring tape that marks inches. Most standard rulers are exactly 12 inches long, but you may wish to use a longer measuring tape for larger items like couches, mattresses and shelves. You can always convert inches to feet after you have your final amounts recorded.

    For example, if you need to find the dimensions of a bookcase in linear feet, start by measuring in a straight line from the bottom of the bookcase to the top. This will give you the bookcase’s height in linear feet and inches. Next you can measure from side to side and back to front to get its width and depth.

    For measurements that are not exact multiples of 12 inches, you can use either feet and inches or a decimal. For example, 54 inches can be expressed as four feet six inches or 4.5 feet.

    Using linear feet has broad applications whenever you need to measure in feet and inches. However, if you need the metric equivalent, one linear foot equals 30.48 centimeters.

    When to measure by linear feet

    The linear foot is a one-dimensional unit you can use to measure anything in a straight line. Freight companies often use linear feet when quoting rates to relocate goods over long distances. When you reserve space with a freight carrier, you’ll only pay for the space you’ll actually use, so accurate measurements are required — you can’t simply say you need enough space for a one- or two-bedroom house.

    Linear feet are also used in the home improvement industry to measure items like dimensioned lumber, trim, fencing, flooring, carpet, countertops and piping. Pricing for these products is typically based on linear footage.

    Measure once you’re packed

    It’s crucial to take measurements at the right stage in the moving process. This should ideally happen once all of your household items are packed in boxes and stacked in one area. This will then give you an idea of what your things will look like once they’re loaded into a container, and you can give accurate measurements to trucking companies and get realistic quotes.

    Know your total linear feet

    Knowing your total linear feet is a good place to start when contacting moving companies. However, they may ask for more information, like square footage and approximate weight. They may even ask for pictures to ensure you get the right size truck and avoid additional fees on moving day if you underestimate your needs.

    Hiring a reputable company can greatly reduce the chance of errors like this. For instance, Marvin, a reviewer from Florida was pleased with Colonial Van Lines’ attention to measurements and the overall move.

    “They called me to make sure that I was on the mark for the actual moving date, whether or not I had more boxes than I anticipated,” Marvin said. “They increased the size of my order, which made me hesitant, but ultimately, it meant that I was paying less per pound. So everything worked out. They anticipated my size very accurately by my descriptions from their questions.”

    Calculating linear vs. square vs. cubic feet

    A linear foot measures the length of a straight line, while a square foot measures the area of a surface and a cubic foot measures the volume of a three-dimensional space.

    How to calculate square feet

    To calculate square footage, you’ll need to multiply two separate measurements, like length and width, length and height or width and height. So, if you want to know how much space your couch will take up on your living room floor, measure the length and depth of your sofa, then multiply the two measurements.

    Because most measurements won’t result in even feet, it may be easier to measure in inches. If you want to convert square inches to square feet, divide the square inch total by 144.

    For example, if your couch is 6 feet 8 inches long and 3 feet wide, you would multiply 80 inches (6 feet plus 8 inches) by 36 inches (3 feet), which equals 2,880 inches. Then, you’ll divide by 144, which equals 20 square feet.

    How to calculate cubic feet

    In comparison, cubic feet measures volume, which is the amount of three-dimensional space an object occupies. To calculate cubic feet, you’ll multiply the length, width and height of an item. This is especially helpful when packing shipping containers or moving trucks to understand how much room your items will take up overall.

    For example, if a box is 3 feet long, 2 feet wide and 2 feet high, the calculation would be: 3 x 2 x 2 = 12 cubic feet.

    Linear feet vs. board feet

    Note that linear footage is not the same as board footage. While a linear foot measures only one dimension at a time (such as length, width or height), a board foot expresses the volume of a piece of lumber. One board foot is equivalent to a piece of wood that is one foot long, one foot wide and one inch thick.

      FAQ

      Is 1 foot the same as 1 linear foot?

      Yes, one foot is the same length as one linear foot, but one linear foot refers to one standard foot that’s measured in a continuous straight line. Both are one-dimensional units that measure distance only, as compared to a square foot, which measures area, and a cubic foot, which measures volume.

      How many linear feet are in a room that’s 10 feet by 10 feet?

      A room that’s 10 feet by 10 feet has 40 linear feet when measuring just the perimeter (10 + 10 + 10 + 10 = 40). As for how many linear feet of moving space you’ll need, it depends on the volume and layout of your packed items rather than the room's dimensions.

      Do I need to know the weight of my items in addition to linear feet?

      Yes, you’ll typically need to know the weight of your items in addition to linear feet. While many moving companies quote prices based on linear feet, some may also factor in weight, especially if you’re moving long distances. Knowing both measurements gives you a more accurate estimate and can help avoid surprise charges.

      What happens if my measurement is off on moving day?

      If you underestimate the space needed, you may face extra charges or require an additional truck, potentially delaying your move. Some companies may adjust the pricing or space on the spot, but it’s best to be as accurate as possible upfront.

      Bottom line

      Getting precise measurements in linear feet can help ensure a smooth moving experience and prevent costly mistakes. If your measurements aren’t accurate, you may not have enough room for all your things when packing a moving truck, which can result in additional fees or worse, like having to schedule another truck to come at a later date to complete the move. You can avoid these complications by getting your measurements right the first time.
