How to Find Studs in Plaster and Lath Walls

Finding studs in plaster and lath walls can be a daunting task, but it's crucial for securely hanging heavy objects without damaging the wall. Rachel Rothman, chief technologist and executive technical director of the Good Housekeeping Institute, shares her expert tips on how to locate studs quickly and easily.

The first method involves gently knocking or tapping the area with a hammer to verify if you've found a stud. This technique is reliable, but it may not always yield accurate results. Another approach is to measure 16 inches from the edge of a window, as windows typically have a stud on each side. However, this method can be less reliable due to the difficulty in finding the edges.

A more reliable method involves looking for dimples in the wall, which are often signs of where drywall is fastened to the edge of a stud, particularly in plaster walls. These dimples may not always be visible to the naked eye, so it's helpful to use a flashlight to illuminate them. Keep in mind that some studs may be spaced 24 inches apart, so it's essential to measure twice.

Another effective way to find a stud is by locating an electrical box. These boxes are typically attached to studs, making it easier to identify their location. Start by finding the nearest electrical box to the area where you want to hang something that requires extra reinforcement.

The most reliable method of all involves finding a light switch or power outlet. According to Rothman, these fixtures are usually attached to studs, making them easy to locate. Once you've found a stud, you can securely hang your object without worrying about it falling or causing damage to the wall.

In conclusion, finding studs in plaster and lath walls is crucial for safely and securely hanging heavy objects. By using one of these methods, you can ensure that your decorations stay put and your wall remains undamaged.
