Sizing Standards Explained
When designing furniture or planning cuts, understanding how plywood sheets are sold is critical. While most DIYers assume plywood only comes in standard 4x8-foot sheets, specialty and import woods follow different sizing standards.

The 5x5 Baltic Birch Sizing Origin
Why does Baltic Birch come in 5x5-foot sheets? Baltic Birch is manufactured in Russia and Eastern Europe. The standard sizing is rooted in the metric system—exactly 1525mm by 1525mm.
When building furniture with 5x5 sheets, plan your cuts carefully. The grain direction always runs parallel to the first dimension listed. On 5x5 sheets, the grain direction is uniform across the entire face.
