🪵 Timber /plywood / moulding Calculation
1. The Importance of Precision
Wood is a precious resource. Accurate measurements prevent wastage and ensure your budget stays on track.
- Avoid over-ordering or under-ordering.
- Speak the same language as your timber merchant.
- Essential for structural stability in heavy construction.
2. Understanding the Units
📏 Running Feet (RFT)
Measures linear length. Best for planks and borders.
Formula: Length (Inches) ÷ 12 = Total RFT
📐 Square Feet (SFT)
Measures surface area. Used for flooring and wall cladding.
Formula: Length (ft) × Width (ft) = Total SFT
📦 Cubic Feet (CFT)
Measures total volume. Standard for bulk wood and heavy beams.
Formula: (Length" × Width" × Thickness") ÷ 1728
*Note: If thickness is already in feet, divide by 144.
*Note: If thickness is already in feet, divide by 144.
3. Common Errors to Avoid
- Mixing Millimeters (mm) and Feet (ft) without conversion.
- Forgetting the 10% wastage allowance during procurement.
- Calculating SFT for bulk beams instead of CFT.
4. Quick Conversion Matrix
| Type | Standard Formula | Practical Example |
|---|---|---|
| Running Feet | L ÷ 12 | 120" Length = 10 RFT |
| Square Feet | L(ft) × W(ft) | 4' × 2' Panel = 8 SFT |
| Cubic Feet | (L×W×T) ÷ 144 | 8"×6"×3' Beam = 1 CFT |

Get Expert ConsultationFrequently Asked Questions (FAQ)
Q1: How do I calculate Timber Volume in CFT?
To calculate Cubic Feet (CFT), multiply the Length, Width, and Thickness in inches and divide the total by 1,728. For example: (12″ x 12″ x 12″) / 1728 = 1 CFT. The OPS International calculator automates this for you.
Q2: What is the difference between CFT and CBM?
CFT stands for Cubic Feet (Imperial unit), while CBM stands for Cubic Metre (Metric unit). 1 CBM is approximately equal to 35.315 CFT. International timber exports, like German Pine, are often calculated in CBM.
Q3: How much wastage should I account for in Plywood?
For standard wood projects, we recommend adding a 5% to 10% wastage buffer. This accounts for cutting losses, grain matching, and edge trimming during the manufacturing process.
Q4: Can I convert MM or CM measurements into CFT directly?
Yes! The OPS International Smart Calculator allows you to input sizes in MM or CM, and it automatically converts them into standard Inch-based CFT for your billing and quotations.
Q5: Is this calculator suitable for all types of wood?
Absolutely. Whether you are dealing with Hardwood (Teak, Oak, Ash) or Softwood (Pine, Spruce), the volume calculation remains the same. You just need to input the specific rates per CFT.
