What is the most common plywood size?

Typically the most commonly used plywood is four by eight foot sheets. When it comes to structural plywood, a supplier will also supply proof of strength performance. This indicates the plywood has passed building regulations and can be used for structural use in building work.

However, it is worth noting general plywood does not have proof of strength performance. In this case, it should not be used for structural applications.

If you are unsure about which plywood size you need or which type you should use, speak to the manufacturer. You can also speak to our advisors using the helpline or check out more about plywood via our Help and Advice guides.
