Understanding plywood grades is crucial when choosing the right plywood for your project. The A-D plywood grading system shows the quality and characteristics of the front and back surfaces of the plywood panel.

The A-D grading system ranks the grade using letters, from A to D. Grade A is the highest quality, with a smooth and uniform surface, free of defects. Usually, two-letter combinations such as AC are used to define the quality of face and back veneers of the plywood panel. The first letter indicates the face veneer, and the second letter shows the back veneer. Sometimes, a suffix like X in “CDX” is added to show the type of glue used to make the panel moisture resistant.
