Freight Weight Estimates

Start With the Actual Shipment, Not a Guess

The best freight weight is a measured weight. FreightCenter recommends using a freight scale when possible and keeping the weight certificate as a record of the measurement. If the shipment can be separated into smaller pieces, another option is to weigh the pieces individually and add the weight of the packaging materials.

Avoid deliberately rounding the number down. If the weight entered when quoting does not match the shipment later measured by the carrier, the difference may result in a billing adjustment.

Include the Pallet, Crate, and Other Packaging

Your freight weight should reflect the shipment as it will actually be tendered for transportation. That means the product itself plus the packaging materials used to prepare it for shipment.

For example, a product may have a manufacturer-listed weight before it is placed on a pallet or protected with additional packing materials. FreightCenter recommends including that additional packaging when determining the total shipping weight.

Use Manufacturer Specifications When They’re Available

For a new or packaged item, check the manufacturer’s specifications before estimating. Those specifications may give you a reliable starting point for both weight and dimensions.

Make sure the specifications describe the item you’re actually shipping. Then add any packaging that is not already included in the listed shipping weight.

Use Density When Weight and Size Need to Be Evaluated Together

Density looks at weight in relation to the amount of space a shipment occupies. The National Motor Freight Traffic Association explains how freight density is calculated using shipment weight and volume. FreightCenter’s density calculator uses the shipment’s weight, length, width, and height to calculate pounds per cubic foot.

For LTL shipments, density can also play a role in determining freight class. That makes accurate measurements important when you are preparing freight weight estimates and comparing quotes.

Measure the Freight After It Is Packaged

Measure the shipment in the form the carrier will receive it. If the item is placed on a pallet or inside a crate, use the outside dimensions of that prepared shipment rather than the dimensions of the product alone.

FreightCenter’s quote and classification tools use length, width, height, and weight as shipment inputs.

Have These Details Ready Before Requesting a Quote

Before entering your shipment, gather:

• Total packaged weight
• Packaged length, width, and height
• Pickup ZIP code
• Delivery ZIP code
• A clear description of what is being shipped
• Freight class when applicable
• Pickup or delivery requirements that apply to the shipment

FreightCenter’s freight calculator uses weight, dimensions, origin, destination, freight class, and service details when preparing rate options.

When You’re Still Unsure, Ask Before You Book

Some shipments are harder to weigh or classify than others. Large equipment, unusual packaging, mixed items, or freight without clear manufacturer specifications can make estimating more difficult.

FreightCenter’s existing weight-estimate guidance recommends contacting a freight expert when you cannot find reliable specifications for the item you are shipping.

That extra check is usually more useful before booking than discovering that one of the shipment inputs was wrong afterward.
