A woodworking and fabrication joint in which two pieces of material are cut at matching angles, typically 45 degrees, and joined together to form a clean corner without exposing the end grain of either piece. Miter joints are used extensively in exhibit casework, frame construction, and millwork where a refined, seamless corner appearance is required. The precision of a miter joint is a direct indicator of fabrication quality and is a standard detail in high-end custom exhibit construction.
