No Thanks

An underrated and often under thought about aspect when it comes to choosing the materials for an upcoming project is shopping for the correct plywood thickness for your project.

Often, it’s not as simple as just plucking a random number or deciding whether you want something to be thick or thin. For certain applications picking the correct thicknesses will help your end product come together much more smoothly and could save you some potential hassles in the future. That’s why we’re going to take a look at how to choose the right thickness for your next plywood project.

Preparing for the project

The first thing you need to keep in mind when it comes to plywood thickness is that there will almost always be a little variance. Manufacturers will always attempt to get the thickness spot-on, but due to the many realities of plywood manufacturing, this isn’t always possible. The sanding process will generally affect thickness from being completely accurate, and much like any wood product it will absorb and lose moisture, which can affect the product's size. However, despite these variances, there are steps you can take to make sure you have planned ahead. Measuring the actual thickness of the shit with callipers is a great idea. It also a good idea to make test cuts if possible, to help you find out if your plywood is going to fit snuggly or not.

It’s important to take these preventative steps to make sure it doesn’t come to building time and you find out your plywood sheets aren’t going to cut it, but just as important is to know what kind of thicknesses you should be looking at for certain applications.

Cabinets & Furniture

Cabinets and furniture generally have the most leeway when it comes to choosing your thickness. These projects are usually stored in safe places inside and aren’t exposed to too many dangers. We find that cabinets are most often made using plywood in 12mm thickness range. The required thickness can vary depending on how big your cabinet is though, as the longer the shelves are the thicker you will want your plywood as it will ensure the sheet won’t sag when placed under pressure. The same applies for building standalone shelves too!

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.

Plywood Walls

If you’re looking to get a little bit adventurous and put in some plywood walls, you would be aiming for 12mm plywood at a minimum as it is a standard requirement. However, depending on the type of building and the processes by which you’re going to be installing the wall you may want to beef up that thickness.
