Understanding the Weight of 18mm Plywood: A Comprehensive Guide

In construction and woodworking, understanding the specific characteristics of materials is vital. One such material is plywood, and it comes in various thicknesses, each with its distinct weight. Today, we will delve into the specifics of one particular type: the 18mm plywood.

What is the Weight of an 18mm Plywood?

The weight of 18mm plywood varies based on the type of wood used and the size of the plywood sheet. However, for a standard sheet size of 8ft x 4ft (or 2440mm x 1220mm), the weight of 18mm plywood is approximately between 27.2kg to 36.56kg.

The Importance of Plywood Weight

The weight of plywood plays a significant role in construction planning. It affects the handling and installation process, structural integrity, and even shipping costs. For example, lighter plywood sheets are easier to handle and move around, while heavier ones can provide more stability and strength.

How Much Does 12mm Plywood Weigh?

While our focus is on 18mm plywood, it’s worth noting that 12mm plywood is also commonly used. The weight of a 12mm plywood sheet of standard size (8ft x 4ft) is approximately 22-24 kg. As with the 18mm version, this weight can vary depending on the type of wood used

Which Shuttering Plywood is Best?

When it comes to shuttering plywood, which is often used for concrete formwork, the best choice depends on your project’s specific needs. However, 18mm shuttering plywood is often preferred for its optimal balance of weight and strength. It’s sturdy enough to withstand the pressure of wet concrete yet light enough for easy handling.

What is 12mm Plywood Used For?

12mm plywood is versatile and finds applications in a variety of projects, including furniture making, paneling, and flooring. Its relatively light weight makes it easy to handle, yet it is sturdy enough for most interior applications.

Understanding Plywood Grades

The term “710 grade plywood” refers to a specific type of plywood that is water-resistant and suitable for use in areas with high moisture content. It’s often used in kitchen cabinets, bathroom furniture, and other areas where the wood could be exposed to water.


Understanding the weight of plywood, like 18mm and 12mm varieties, is crucial in construction and woodworking projects. It helps determine the ease of handling, structural integrity, and even the cost of transportation. Always remember to consider these factors when choosing the right plywood for your project.
