How to Calculate Pallet Weight and Load Capacity
A practical method for estimating a wooden pallet's weight from its board volume and wood density, plus what static, dynamic and racking load ratings really mean.
Two numbers decide whether a pallet is fit for a job: how much it weighs, and how much it can carry. Both can be estimated before you cut a single board. This article shows the simple method behind the numbers.
Estimating weight
A wooden pallet's weight is just the total volume of timber multiplied by the wood's density. For each component — deck boards, stringers or blocks — multiply length × width × thickness × quantity to get a volume in cubic metres, add them all up, then multiply by the density of the wood in kg/m³.
- Softwood (pine, spruce): roughly 450–550 kg/m³ at typical moisture.
- Hardwood (oak, beech): roughly 650–800 kg/m³ — heavier and stronger.
- Moisture matters: freshly sawn wood can weigh far more than kiln-dried timber.
For example, a EUR 1 pallet contains roughly 0.045 m³ of timber; at ~500 kg/m³ that is about 22–23 kg, which matches the real-world figure.
The three load ratings
- Static load: the maximum weight a pallet can hold resting on a solid, flat floor — the highest number.
- Dynamic load: the maximum weight while the pallet is being moved by a forklift or pallet jack — usually much lower.
- Racking load: the maximum weight when the pallet is supported only at its edges in racking — the most demanding, and the one that causes failures if ignored.
What changes the numbers
Deck-board thickness and coverage, block or stringer size, wood species, and how evenly the load sits all change capacity. A pallet rated for 1500 kg dynamic might be rated far lower for racking. Always design to the worst case your pallet will actually see.

PalletDrawing computes estimated weight, overall height and load capacity live as you edit the parts table, using the wood density you set. Change a board width or wood type and the figures update instantly — so you can hit a target weight or capacity before production.
