About

Wholesale lumber and plywood are frequently sold by total volume in cubic meters (m³), whereas construction sites and workshops consume material by the sheet count. A discrepancy in ordering can lead to material shortages or excess inventory costs.

This tool converts bulk volume back into physical sheet quantities. It supports standard international sizes (4x8 ft metric equivalents) and specific thicknesses ranging from 3mm to 21mm. The calculation is precise, treating the volume as a solid block of stacked sheets, and provides the exact count alongside the remaining partial volume.

Formulas

The calculator determines the volume of a single sheet (v) and divides the total shipment volume (V) by this unit.

v_sheet = L × W × T

Count = V_totalv_sheet

Note: All dimensions must be converted to meters before multiplication (e.g., 18mm = 0.018m).

Frequently Asked Questions

The most common global standard is 4 feet by 8 feet. In metric, this is usually 1220mm x 2440mm. Another common size is 5x5 feet (1525mm x 1525mm), often used for Baltic Birch.

No. The input volume should be the "Net Volume" of the wood itself, not the "Gross Volume" of the shipping crate.

Mathematically, a specific volume might equal 50.5 sheets. In reality, you cannot have half a sheet shipped in a bulk block usually, but it indicates 50 full sheets and one partial or waste factor.
