In this article, we’ll cover the five most common mistakes in beam sizing and provide practical tips to avoid them. By leveraging tools like TimberTec, you can ensure precise, compliant, and efficient beam sizing for your projects.
Misreading Span Tables
Span tables are an essential resource for beam sizing, providing information on the load capacity of beams based on span lengths and material types. However, they can be overwhelming, especially for complex projects.
Why It’s a Problem
Misreading span tables can result in beams that are either too small (compromising safety) or unnecessarily large (wasting money). Both scenarios impact project efficiency and cost-effectiveness.
How to Avoid It
- Double-Check Details: Carefully review the project specifications, including spans and loads, before consulting span tables.
- Use Automated Tools: Software like TimberTec eliminates the need to manually interpret span tables by calculating beam sizes based on your input.

Ignoring Load Requirements
Load requirements vary depending on the type of beam and its intended use, such as supporting roofs, floors, or walls. Neglecting to account for specific load conditions is a common error in manual beam sizing.
Why It’s a Problem
Failure to consider live and dead loads can lead to under-designed beams, resulting in structural issues, or over-designed beams, increasing costs unnecessarily.
How to Avoid It
- Consult Engineers: For complex projects, seek input from structural engineers to ensure accurate load calculations.
- Leverage Smart Tools: TimberTec calculates beams based on precise load data, ensuring accuracy and compliance with Australian standards.

Neglecting Deflection Limits
Deflection refers to the amount a beam bends under load. Ignoring deflection limits during sizing can result in beams that don’t perform as expected. That’s why correct plan measurements and beam selection is important.
Why It’s a Problem
Excessive deflection compromises structural stability and can lead to cracked walls, sagging floors, or other structural failures.
How to Avoid It
- Review Deflection Guidelines: Always consider the deflection limits specified in the project’s structural plans.
- Automate Calculations: With TimberTec, deflection limits are automatically factored into beam sizing, ensuring optimal performance.

Overlooking Material Properties
Beams come in various materials, including timber, steel, and LVL (Laminated Veneer Lumber). Each material has unique properties that affect its load capacity and behavior.
Why It’s a Problem
Selecting the wrong material for a beam can lead to over-engineering (increased costs) or underperformance (safety risks).
How to Avoid It
- Understand Material Options: Familiarise yourself with the properties of different beam materials and their applications.
- Rely on Software: TimberTec incorporates material properties into its calculations, helping you choose the best option for your project.
Failing to Account for Code Compliance
Building codes are in place to ensure safety and quality. Ignoring these requirements when sizing beams can result in failed inspections, project delays, or legal issues.
Why It’s a Problem
Non-compliance can lead to costly rework and damage to your reputation as a builder.
How to Avoid It
- Stay Updated: Regularly review updates to Australian building codes.
- Use Compliant Tools: TimberTec aligns its calculations with Australian building standards, ensuring all beams are sized accurately and legally.
