Stud
Affiliate link — we may earn a commissionA stud is a vertical framing member in a wall, typically a 2x4 or 2x6 standing on its narrow edge. Studs run from the bottom plate (sill plate) to the top plate, spaced 16 inches on center in load-bearing walls and sometimes 24 inches in non-load-bearing partitions. In newer construction, you might find metal studs, which are C-shaped galvanized steel channels. The stud is what you screw into when you hang anything heavy on a wall. A drywall anchor in hollow wall holds 15 to 50 lbs. A screw into a wood stud holds 80 to 100+ lbs.
Why It Matters
Every heavy wall mount, shelf bracket, TV mount, and cabinet needs to hit at least one stud. Two studs is better for anything over 50 lbs. If you can't find a stud where you need one, use a toggle bolt rated for the weight. Knowing stud spacing (16 or 24 inches) helps you predict where the next one is after you find the first.
