In a rental, you cannot afford to guess where the studs are. A shelf that pulls out of drywall leaves a hole you have to fix, and a TV that falls is worse. A stud finder tells you exactly where the framing is, so you can anchor into something solid.

This guide explains how stud finders work and three that handle apartment walls well.

Quick answer
  1. Best overall: an electronic stud finder with a deep-scan mode.
  2. Best budget: a magnetic stud finder that finds the screws.
  3. Best for thick walls: a deep-scan model that reads through 1.5 in.
  4. Also useful: a level, so the shelf is straight.
  5. Tip: mark both edges of the stud, not just the centre.

How stud finders work

TypeHow it worksBest for
MagneticFinds the screws holding the drywallQuick, cheap, reliable
Electronic (capacitive)Senses density changes in the wallFinding stud edges
Deep-scanReads through thicker wallsLath, plaster, thick drywall
Edge-findingFinds the stud edge, not the centrePrecise placement

Magnetic stud finders are the simplest and most reliable. They find the screws that hold the drywall to the stud, which is exactly where the stud is. Electronic finders sense density changes and can be fooled by pipes or thick plaster, but they are faster on standard drywall.

Using one on apartment walls

  1. Clear the wall and remove anything hanging.
  2. Slide the finder slowly across the wall, not fast.
  3. Mark both edges of the stud, then the centre.
  4. Verify with a second method — a magnet or a thin nail.
  5. Check for wires and pipes before drilling.
  6. Use the right anchor for the load.
Bottom line

For apartment walls, a magnetic stud finder is the most reliable and cheapest option. An electronic finder is faster on standard drywall. Mark both edges of the stud, verify with a second method, and check for wires before drilling.

Frequently asked questions

What is the best stud finder for apartment walls?
A magnetic stud finder like the CH Hanson 03040. It finds the drywall screws, never gives a false reading, and needs no batteries.
How do I find a stud without a stud finder?
Tap the wall and listen for a solid sound, or use a strong magnet to find the drywall screws. Studs are usually 16 inches apart.
Are electronic stud finders accurate?
On standard drywall, yes. They can be fooled by pipes, thick plaster or lath, so verify with a second method before drilling.
How do I hang a shelf in a rental without a stud?
Use heavy-duty drywall anchors rated for the load. For anything heavy, find a stud — anchors alone are not enough.
Can a stud finder detect wires?
Some electronic models detect live wires as well as studs. Always check for wires and pipes before drilling into a wall.
