How is the size of a jointer indicated?

The size of a jointer is typically indicated by the length of its infeed and outfeed tables, which are measured in inches. Common sizes include 6-inch, 8-inch, and 12-inch models, referring to the width of the cutter head. Additionally, the overall capacity of the jointer, such as the maximum width of material it can joint, is also a key factor in determining its size. Larger jointers are generally used for processing wider boards and handling more extensive woodworking projects.
