In short: one cubic meter holds 22 boards of 50×150 mm at 6 m, 44 boards of 25×150 and 33 boards of 50×100. For 150×150 timber at 6 m it is 7 pieces, for 100×100 — 16. Full tables for boards and timber, lineal and square meters per cubic meter, and the formula for any length follow below.
The count depends on both the cross-section and the length — the longer the board, the fewer fit into 1 m³. The tables use a 6-meter length, the most common lumber length on the Russian market.

Pieces are rounded down to whole boards so the real yield per cubic meter is not overstated. Metric-to-inch sizes are rounded reference conversions, not North American nominal lumber sizes. Board feet per piece computed at a 6 m ≈ 19.7 ft length; lineal meters do not depend on the length.
Timber per 1 m³ at a 6 m length
| Section, mm (≈ in) | Volume per piece, m³ | Board feet per piece | Pieces per 1 m³ | Lineal meters per 1 m³ |
|---|---|---|---|---|
| 100 × 100 (≈4 × 4) | 0.06 | ≈ 25.4 | 16 | 100 |
| 100 × 150 (≈4 × 6) | 0.09 | ≈ 38.1 | 11 | 67 |
| 100 × 200 (≈4 × 8) | 0.12 | ≈ 50.9 | 8 | 50 |
| 150 × 150 (≈6 × 6) | 0.135 | ≈ 57.2 | 7 | 44 |
| 150 × 200 (≈6 × 8) | 0.18 | ≈ 76.3 | 5 | 33 |
| 200 × 200 (≈8 × 8) | 0.24 | ≈ 101.7 | 4 | 25 |
Rounded down to whole pieces.
How many square meters are in a cubic meter of boards
The area a cubic meter of boards covers depends only on the thickness: 1 ÷ thickness in meters. Width and length do not matter.
| Board thickness, mm | m² per 1 m³ |
|---|---|
| 20 | 50 |
| 25 | 40 |
| 32 | 31.25 |
| 40 | 25 |
| 50 | 20 |
Recalculating for your own length
Volume per board = thickness × width × length (in meters). Pieces per 1 m³ = 1 ÷ volume per board. A 25×150 mm board cut to 3 m (half the table’s length) has a volume of 0.025 × 0.15 × 3 = 0.01125 m³ — about 89 boards per cubic meter, nearly double the 6 m figure.
For a non-standard section, a mixed-length batch, or a straight board-feet total, it’s faster to enter your own sizes into the calculator than to interpolate the table by hand.
FAQ
How many 50×150×6000 mm boards are in one cubic meter?
22. One board is 0.05 × 0.15 × 6 = 0.045 m³, and 1 ÷ 0.045 ≈ 22.2 — 22 whole boards.
How many 25×150×6000 mm boards are in a cubic meter?
44: one board is 0.0225 m³, and 1 ÷ 0.0225 ≈ 44.4.
How many 50×150 boards 4 m long are in a cubic meter?
33: one 4 m board is 0.03 m³, and 1 ÷ 0.03 ≈ 33.3.
How many pieces of 150×150×6000 mm timber are in a cubic meter?
7: one piece is 0.135 m³, and 1 ÷ 0.135 ≈ 7.4. For 100×100×6000 mm timber it is 16 pieces.
How much is a cubic meter of boards?
A cubic meter is a volume. Boards 25 mm thick cover 40 m² per cubic meter, 50 mm boards cover 20 m². For 50×150 boards a cubic meter is 133 lineal meters — 22 boards of 6 m.
Why does a seller count a different number of boards per cubic meter?
Lumber is sold in whole boards, so a "cubic meter" is usually slightly less than 1 m³: 22 boards of 50×150×6000 mm are 0.99 m³, and 66 boards of 25×100×6000 mm are also 0.99 m³. A seller may also count by the nominal section, while the actual section after drying or planing is smaller. Check it with the formula: thickness × width × length × quantity.
