The Logistics of Wood Chipping
For professional arborists and tree service companies, taking down the tree is only half the job. The real logistical bottleneck is hauling it away. If your crew fills up the chip truck before the tree is entirely processed, production stops. You are forced to pay your crew to sit around while a driver makes an unbillable trip to the dump.
By calculating the exact cubic yards of mulch a tree will produce *before* you quote the job, you can ensure you bring the right sized equipment (or a second truck) to finish the job in a single trip.
Understanding the "Bulking Factor"
Solid wood is incredibly dense. When you run branches and trunk sections through a commercial wood chipper, you introduce massive amounts of air between the wood fragments. In the arboriculture industry, this is known as the "bulking factor" or expansion rate.
- Solid to Chipped Expansion: Solid wood generally expands by 2.0 to 2.5 times its original volume once chipped. Our calculator uses a standard median multiplier of 2.2x.
- The Math: If you calculate that a tree trunk contains 10 solid cubic yards of wood, you must plan for approximately 22 cubic yards of loose wood chips to hit the back of your truck.
How the Calculator Measures Trees
To estimate the volume, we treat the tree trunk as a mathematical cylinder. By entering the Diameter at Breast Height (DBH) and the total height, we calculate the solid cubic feet of the trunk.
Because a tree isn't just a pole, we then apply a Canopy Density multiplier. A sparse pine tree might only add 20% more volume in branches, whereas a dense, mature maple canopy could add 60% more volume to the final chip pile. The engine runs these parameters instantly to project your total truckloads.
