Truck Bed Capacity – Project Calculator Pro

Truck Bed Cubic Yard & Payload Calculator

Estimate your truck bed’s usable volume, the weight of a selected material, and whether the planned load may exceed the truck’s available payload capacity.

Calculator Settings

Truck or Bed Description (optional)

Measurement Unit

Enter all truck-bed and wheel-well measurements in inches.

Truck Bed Measurements

Measure the inside of the truck bed. Use the average planned material depth rather than the highest point of a rounded or heaped load.

Inside Bed Length (in)

Inside Bed Width (in)

Measure from inside wall to inside wall. Enable the wheel-well adjustment below when applicable.

Planned Material Depth (in)

Enter the average level depth of material you plan to place in the bed.

Wheel-Well Adjustment

Subtract wheel-well space Enable this when your bed width was measured from wall to wall. Leave it disabled if you measured only the open width between the wheel wells.

Material Weight

Select a material to load an approximate starting density. You can edit the density to match information supplied by your material provider.

Material

Material Density

Material weight varies with moisture, compaction, particle size, and supplier.

Vehicle Payload

This section is optional. Enter the rated payload from the truck’s Tire and Loading Information label to estimate a payload-limited load.

Rated Payload Capacity (optional)

Use the payload rating—not the towing capacity.

Driver and Passenger Weight

Tools and Other Cargo

Toolbox and Accessory Weight

Trailer Tongue Weight

Optional Trip Planning

Calculate the estimated number of trips Enter the total amount of material you need to transport.

Result Options

Show detailed volume and payload calculations Includes wheel-well displacement, metric conversions, payload usage, safe depth, and limiting capacity.

Calculator Assumptions

Truck Bed Shape: Rectangular bed with optional rectangular wheel-well deductions
Cubic Yard: 27 cubic feet
Short Ton: 2,000 pounds
Payload Warning Range: Near-limit warning begins at approximately 80% of available material payload

This calculator provides planning estimates only. A truck bed may physically hold more material than the vehicle can safely carry. Do not exceed the payload, gross vehicle weight, axle, wheel, or tire ratings specified for your vehicle. Material density and actual load distribution can vary. Verify ratings on the vehicle labels and confirm the material weight with the supplier before loading.
