Versatility – 12mm plywood can be used in many general purpose applications, such as internal and external joinery (providing it is properly sealed). Strength – Thanks to the cross-graining process by which it is manufactured, it has a high strength-to-weight ratio. It also provides a high level of impact resistance.

Plywood Furniture

When it comes to furniture, you’ll find that an 18 to 24mm plywood sheet thickness is perfect for building tables, while a set of draws will use a combination of 6mm plywood and 12mm plywood. If you’re looking to craft something that needs to be sturdy and take a fair amount of weight such as this sideboard from Australian Furniture Designer Matt Blatt, you’re going to be looking at a thicker sheet of plywood. On the other hand, decorative pieces that won’t have weight pressing down on it will generally be fine on the lower end of the thickness scale.
