Plywood 101 - what is plywood

Plywoods are versatile and popular engineered wood products used in various woodworking applications. It is made up of thin layers of wood veneer (plys) that are glued together, each rotated 90 degrees to the one below it for increased stability and strength.

Ply wood is one of the 6 types of boards I have discussed in my article 6 Types of Wood Boards – Best guide for Woodwork Beginners. Be sure to check out that article to discover other types and pick the right one for your projects.

Plywood Grades

Ply wood is graded based on its quality, durability, and intended use. This wood classification system combines letters (A, B, C and D) and numbers (1 to 4) to gauge the quality and purpose of the timber. The grades it encompasses are:

  • A-grade ply wood: the highest quality, with no defects and a smooth, sanded surface finish, commonly used for fine woodworking, cabinetry, and furniture-making.
  • B-grade ply wood: contains slight surface defects and may have some repaired knots or wood filler, typically used for furniture backs and cabinet interiors.
  • C-grade ply wood: may have visible knots or splits, and is suitable for construction applications where appearance is not a major concern.
  • D-grade ply wood: contains numerous knots and defects and is generally used in roof supports and sheathing applications.

Plywood Strength and Durability

Strength and durability depend on various factors such as wood species, thickness, glue types, and manufacturing processes. Some common factors that determine ply’s strength include:

  • Number of veneers: More veneers make ply wood stronger as more layers distribute stresses across the wood.
  • Glue types: Different glue types affect ply wood strength differently. For example, exterior-grade glue is ideal for outdoor applications and marine ply wood, while interior-grade glue is typically used for indoor applications.
  • Moisture content: Ply wood with low moisture content is stronger and more stable.

Plywood Sizes and Thicknesses

Different measurements and depths make layered wood ideal for a variety of uses. These materials generally come in thicknesses of 6 millimeters (1/4 inch), 12 millimeters (1/2 inch), 18 millimeters (3/4 inch), and 25 millimeters (1 inch). Here are some standard plywood sizes:

  • The most prevalent size is 4 feet by 8 feet (122 cm x 244 cm).
  • Smaller sizes such as 2 feet by 2 feet (61 cm x 61 cm), 2 feet by 4 feet (61 cm x 122 cm), and 4 feet by 4 feet (122 cm x 122 cm) are appropriate for compact ventures such as furniture building and do-it-yourself (DIY) tasks.
