Timber volume and board feet: practical guide
This guide explains how to use the Count.ie timber volume and board feet. Calculate sawn timber volume and cost for repeated pieces. Follow the inputs, method and worked example below, then compare your own scenario.
Guide written .
Open the Timber volume and board feet calculatorWhat to prepare
- Measure the actual space and record every dimension with its unit.
- Check the supplier's pack size, stated coverage and installation instructions.
- Separate the measured requirement from waste, cuts, overlaps and spare material.
Understand the inputs
The calculation method
Volume = thickness × width × length × pieces. One cubic metre is approximately 423.776 board feet.
Worked example
Illustrative inputs and their result.
Example inputs
- Thickness (mm)
- 50
- Width (mm)
- 150
- Length per piece (m)
- 4.8
- Pieces
- 20
- Timber price (€/m³)
- 650
Calculated example result
- Volume M3
- 0.72 m³
- Material Cost
- €468.00
How to interpret the result
The calculated quantity is a planning estimate, not an installation specification. Whole packs and site conditions can change the order; structural or safety-critical work needs appropriate professional guidance.
Compare alternative dimensions or pack sizes without changing the unit basis. Re-measure uncertain areas before buying, and use the manufacturer's instructions to decide a suitable allowance.
Common mistakes to avoid
- Convert millimetres, centimetres and metres before combining measurements.
- Do not add the same waste allowance at both measurement and ordering stages.
- Check irregular shapes, openings, substrate conditions and manufacturer coverage separately.
Assumptions and sources
Uses entered actual dimensions. Planed sizes, grading, treatment, offcuts and structural performance require separate allowance.
