LUMBER WEIGHT REFERENCE
The lumber weight reference library
Dedicated guides to lumber weight, species density, actual dimensions and moisture, with shipping references when needed.
Check the volume, density and condition behind the weight
Use actual dimensions and a density whose moisture basis is stated. Keep unlike pieces separate, then add packaging once as tare. The guides explain a transparent estimate and its uncertainty; measured shipment weight remains a separate record.
Density & evidence
Density & evidence
Choosing wood density for a lumber weight estimate
Match the density input to the product, measurement method and moisture condition you are actually estimating.

Density & evidence
Density and specific gravity are different inputs
Understand why a dimensionless specific-gravity entry cannot simply be typed into a pounds-per-cubic-foot field.
Open resource ↗Density & evidence
Use a measured sample without overstating it
Record mass, physical volume, condition and sample scope before using a measured density in a larger estimate.
Open resource ↗Density & evidence
Show uncertainty with a density range
Use separate, labeled scenarios to see how uncertainty affects the result without calling the range a confidence interval.

Hardwood weight requests: what to ask the supplier
Prepare a specific weight-information request for Ipe, Cumaru and other hardwood products without assuming a species average is a shipping guarantee.
Open resource ↗Volume & units
Volume & units
Use actual dimensions for a physical weight estimate
Distinguish a product designation, a commercial tally and the dimensions of the physical material being moved.

Board feet to weight: check the tally first
One board foot is a volume unit, but the number on a commercial tally may use a different measurement convention.
Open resource ↗Volume & units
Calculate lumber weight in metric units
Keep millimeters, meters, cubic meters and kilograms aligned through the complete calculation.

Weight estimates for grooved and profiled lumber
Recognize when width × thickness describes an envelope rather than the actual material section.
Open resource ↗Moisture
Moisture
How moisture basis affects lumber weight calculations
Read dry-basis moisture content correctly and separate a measured condition from a drying label.
Open resource ↗Moisture
Green and dry lumber: compare conditions, not labels
Understand the inputs needed before estimating how a change in moisture affects the weight of the same wood.

Bundles & freight
Calculating the weight of a mixed lumber bundle
Build a line-by-line total for boards that do not share one size, count or density basis.

Bundles & freight
Net, gross and tare for lumber shipments
Separate the material subtotal from pallets, wrapping, stickers and other shipment components.

Estimated lumber weight versus a scale ticket
Recognize what a geometric model can explain and what it cannot establish about an actual shipment.
