Select the most efficient timber cross-section for your design

About timbersizerPro EC5 edition

Using timber sizes readily available in the UK market, timbersizer suggests appropriate cross-sections based on timber strength classes C16 or C24, or joist depth. This allows you to specify the most appropriate timbers available, or ones that give the optimum floor/ceiling depth.


Comply with the latest Eurocode standards

Based on the Eurocodes 0, 1 and 5 and their UK National annexes, timbersizerPro calculations are appropriate for all designs compliant with Eurocode standards.

The timbersizer service is regularly reviewed to keep it abreast of any modifications and changes to the Eurocode standards. This helps you to ensure your designs are compliant with the latest codes.
