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
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.
Measure from inside wall to inside wall. Enable the wheel-well adjustment below when applicable.
Enter the average level depth of material you plan to place in the bed.
Wheel-Well Adjustment
Only the portion below the entered material depth should be deducted.
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 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.
Use the payload rating—not the towing 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.
Truck Loading Tips
- Measure the inside usable dimensions of the bed rather than relying only on the manufacturer’s advertised bed length.
- Use the truck’s actual payload information when available instead of assuming that every truck within the same model class has the same capacity.
- Account for passengers, tools, accessories, cargo, and trailer tongue weight before determining remaining payload.
- Confirm bulk-material weight with the supplier when possible because moisture and material composition can substantially affect weight.
- Dense materials may reach the payload limit well before the truck bed appears full.
- Keep the load distributed appropriately and secure loose material before traveling.
- When an estimated load is close to a vehicle limit, verify the actual loaded weight rather than relying only on the calculator.
Truck Bed Capacity & Payload Calculator
Know How Much Your Truck Can Carry Before You Load It
The Project Calculator Pro Truck Bed Capacity Calculator helps estimate how much material will physically fit in a pickup bed—and whether the truck has enough payload capacity to safely carry the estimated weight.
Enter the inside dimensions of the truck bed, material depth, wheel-well adjustment, material type, and available payload. The calculator estimates truck-bed volume, cubic feet, cubic yards, material weight, available payload, safe material depth, and the number of trips required.
This is especially useful when hauling gravel, mulch, topsoil, compost, sand, crushed stone, firewood, concrete, landscaping materials, or other bulk products. A truck may have enough bed space for a material while reaching its payload limit long before the bed is full.
Frequently Asked Questions
How do I calculate the cubic yards in my truck bed?
Measure the usable inside length, width, and material depth. Multiply the dimensions to determine cubic volume and convert that result to cubic yards. There are 27 cubic feet in one cubic yard. Project Calculator Pro performs these conversions automatically.
How many cubic yards can a pickup truck hold?
There is no single capacity that applies to every pickup. Truck beds vary in length, width, wheel-well dimensions, side-wall height, and usable space. Entering the actual truck-bed measurements provides a better volume estimate than relying on a general truck-size category.
Can I fill my pickup bed completely with gravel?
Not necessarily. Gravel is relatively dense, so a truck may reach its payload limit before the bed is physically full. The calculator compares estimated gravel weight with the available payload entered for the vehicle.
How much does a cubic yard of material weigh?
Weight depends on the material and its condition. Mulch may be relatively light, while soil, sand, gravel, crushed stone, and concrete can be much heavier. Moisture content and material composition can also change actual weight. Use supplier-provided weight information when available.
Does payload include passengers?
Vehicle payload generally represents the total additional weight carried by the vehicle rather than only material placed in the bed. Passengers, cargo, equipment, accessories, and other loads can therefore reduce the payload available for bulk material.
Should I use truck-bed volume or payload to determine how much material I can haul?
Consider both. The usable load is limited by whichever restriction is reached first. Lightweight materials may be limited by available bed volume, while dense materials may be limited primarily by vehicle payload.
Can this calculator tell me how many trips I need?
Yes. When the total project material quantity is entered, the calculator can compare that amount with the estimated usable capacity of the truck and provide a planning estimate for the number of loads required.
