Measure from window and door frames

Every window and door opening has studs on both sides — a full-height king stud and a shorter jack stud. The outermost stud is close to the edge of the trim casing. From there, measure 16 inches toward the rest of the wall to predict subsequent studs.

Why It Works

Building code requires structural framing around all openings. These studs are always present and provide a reliable reference point, especially useful when you are far from a corner or outlet.

Tips

• The king stud center is roughly 2-1/4 inches from the edge of the trim casing
• Cripple studs above and below windows maintain the 16-inch spacing pattern
• Confirm predicted locations with knocking or a magnet before drilling
• In older homes, framing around openings may be non-standard
