1. What is Building Regulation Timber Span Tables?

Definition: This calculator computes the volume of timber using standard UK building regulation sizes.

Purpose: It helps builders, architects, and DIYers determine timber volume for construction projects while complying with UK building standards.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of timber (cubic meters)
• \( L \) — Length of timber (meters)
• \( W \) — Width of timber (meters)
• \( H \) — Height/Depth of timber (meters)

Explanation: The formula calculates the three-dimensional space occupied by a timber piece.

3. Importance of Timber Volume Calculation

Details: Accurate volume calculation ensures proper material ordering, structural integrity, and compliance with UK building regulations.

4. Using the Calculator

Tips: Enter the length, width, and height in meters. All values must be > 0. The calculator uses standard UK building regulation timber sizes.

5. Frequently Asked Questions (FAQ)

Q1: What are standard UK timber sizes?
A: Common sizes include 47x100mm, 47x125mm, 47x150mm, etc., but always check current building regulations.

Q2: Does this account for timber spacing?
A: No, this calculates single timber volume. For multiple pieces, multiply by quantity.

Q3: Can I use different units?
A: Yes, but ensure all dimensions use the same unit for accurate results.

Q4: How does this relate to span tables?
A: Volume calculation is the first step before consulting span tables for structural requirements.

Q5: Should I add extra for waste?
A: Yes, consider adding 10-15% to the calculated volume for cutting waste and defects.
