How accurate are the density values?

The densities used are average dry values per species. Actual weight varies with moisture content, grain, and grading. Green (freshly cut) lumber can weigh 30–100% more than dry lumber.

Why does plywood weigh more than solid wood of the same species?

Plywood uses cross-laminated veneers bonded with adhesive, which slightly increases density. MDF is even heavier because it is compressed wood fiber plus resin binders.

Can I calculate weight for non-rectangular sheets?

This tool assumes rectangular sheets. For non-rectangular shapes, calculate the bounding rectangle weight and multiply by the fraction of material remaining.

What is the difference between nominal and actual thickness?

Lumber is sold by nominal size (e.g., 1-inch board) but actual milled thickness is less (e.g., 3/4 inch). Always measure actual thickness or check your supplier's spec sheet for accuracy.

Does moisture content matter?

Yes. Kiln-dried lumber (moisture content ~8–12%) weighs significantly less than green lumber. The densities here represent air-dry or kiln-dry values typical for construction use.
