How Movers Calculate Weight, and How to Dispute It
Most long-distance moves are priced by weight. On a non-binding estimate, the estimated weight is a guess and the scale decides the bill. Federal rules set out exactly how that weighing must be done, and you have the right to watch it, ask for a reweigh and see the weight tickets.
When weight decides the price
An interstate quote is either binding, where the price is fixed regardless of the final weight, or non-binding, where the estimate is based on an expected weight and the final charge follows the actual weight. Binding not-to-exceed estimates sit between the two: you pay the lower of the estimate and the actual weight-based charge. Our quotes guide covers the three types. This page is about the second and third, where the scale matters.
Movers estimate weight from the survey of your belongings, often by estimating volume first and converting it to pounds. A common industry factor is around 7 pounds per cubic foot. If the estimate is given by volume and converted to weight, the mover must explain the conversion in writing.
How the shipment must be weighed
A weight-based shipment must be weighed on a certified scale, using one of two methods:
- Origin weigh. The empty truck is weighed before loading (tare weight) and again after loading (gross weight). The difference is your shipment.
- Back weigh. The loaded truck is weighed before delivery and again empty after unloading.
For both weighings, the truck must carry all the pads, dollies, ramps and equipment it uses on the job, nobody may be on the truck, and the fuel tanks must be full each time, or, on an origin weigh, no fuel may be added between the two weighings. Those conditions exist for a reason: equipment loaded only for the gross weighing, or fuel added in between, inflates your shipment weight.
Shipments of 3,000 pounds or less can instead be weighed on a certified platform or warehouse scale, before loading or after unloading.
Your rights at the scale
- You may watch every weighing. The mover must tell you where and when each weighing will happen and give you a reasonable chance to be there. If you do not attend, you are treated as having waived that right for that weighing.
- You may demand a reweigh. On a shipment weighed at origin, once the mover tells you the billing weight and charges, you can demand a reweigh before unloading begins. The bill must then be based on the reweigh.
- You must get weight tickets. Each weighing produces a ticket signed by the weighmaster, showing the scale, date, tare or gross, the truck, your name and the shipment number. True copies must come with your bill.
- You can ask for the weight and charges in advance. If you request it and give a contact, the mover must tell you the actual weight and charges at least one full business day before delivery, with some exceptions.
Spotting a weight that does not add up
Compare the billed weight to the estimated weight on your estimate. A large jump with no new items is worth questioning. Ask to see both weight tickets and check the scale name, dates and truck number match. If anything looks wrong, request a reweigh before unloading starts, not after.
Remember the delivery cap, too. On a non-binding estimate, the mover cannot demand more than 110 percent of the estimate at delivery, plus services you added and any impracticable operations charge. Any balance must be billed later, which gives you time to dispute it. Our guide to moving scams explains why that cap matters.
Reducing what you pay for
On long hauls, weight is the lever you control. Books, heavy furniture, exercise equipment and garage contents add up quickly. Selling or donating them before the move often costs less than moving them 1,500 miles. Get the estimate after you have decided what is going, not before.
