Tap the wall and listen for a solid, less hollow sound
Look for electrical outlets, switches, or wall plates, since studs are often beside them
Measure 16 inches from a known corner or nearby stud location
Check for nail or screw pops in the drywall
Use a strong magnet to find drywall screws or nails
Remove a small cover plate and inspect the stud placement behind it
Look in the attic, basement, or crawlspace for framing alignment
Use a flashlight at an angle to spot slight wall surface imperfections
Drill a tiny test hole in an inconspicuous spot to confirm
Verify stud direction by finding one and measuring across the wall
