In a 1970s house, wall studs are typically spaced 16 inches on-center (measured from the center of one stud to the center of the next). However, depending on local building codes and the wall's structural load, some exterior walls or non-load-bearing partitions may be spaced 24 inches on-center.
Studs in older homes are generally 16 to 24 inches apart. Check which side of your outlet is attached to the stud and measure off the next 16-24 inches to find the next one. You can use any of the above methods to ensure you've found the next stud on your wall.
Vertical studs stand between the header and footer across the wall. They are usually placed 16 inches apart on all walls. It can vary in older homes, but rarely would you find studs more than 24 inches apart.
Most homes were built with 16 or 24 inches between studs. Some older homes may have oddly spaced distances between studs, however. You can also try knocking on the wall. You should hear a slightly different sound where studs might be.
In a 1950s house, wall studs were typically spaced 16 inches on center (OC). While 16 inches is the standard convention, older homes can occasionally have variations where spacing ranges between 12 to 24 inches depending on the builder or region.
A photo I took comparing new 1/2” drywall (left of door frame) to 50's-60's era interior walls. I believe it's 3/8th” gyprock lath, with a healthy layer of plaster over top (maximum thickness 5/8” at points).
That will be the nails holding the lath in place, and will be near the center of the stud. Typically studs will be 16” on center, but could be 24” if 2x6.
Lath and plaster walls fell out of standard residential construction between the 1940s and 1960s. While traditional three-coat plaster was the go-to method for centuries, a massive post-WWII housing boom popularized drywall (Sheetrock), which was significantly cheaper and faster to install.
Having studs spaced 24 inches apart instead of the standard 16 inches is a common framing method used to save on lumber costs and improve energy efficiency.
Common framing mistakes—whether in residential construction, cognitive psychology, or digital communications—can ruin an entire project. Below is a breakdown of the most common errors in the physical, logical, and technical fields.
Finding studs in an old house (typically built with lath and plaster) can render electronic stud finders useless. Instead, use the most reliable methods below, relying on physics and old-school carpentry techniques:
Wood-framed houses have traditionally been built with 2x4 studs spaced 16-inches on-center. Research has shown exterior framed walls can be adequately supported by 2x6 studs spaced 24-inches on-center.
Choose 1/2-inch drywall for the walls for an easy installation and budget-friendly finish. Choose 5/8-inch drywall for the ceiling to prevent sagging and improve fire safety. If your basement includes a utility room or an attached garage, your local building codes likely require fire-rated 5/8-inch (Type X) board on those shared walls.
In a 1960s house, wall studs are most commonly spaced 16 inches apart (on center), though it is entirely possible to find 24-inch spacing in some non-load-bearing walls or regions built with specific materials.
Sistering with a partial stud is not allowed by most building codes for load-bearing walls. In this case, a bad stud must be sistered by a new full stud that extends from the wall's bottom plate, or sole plate, to its top plate. The sister stud must be anchored to both plates as well as to the damaged stud.
To know if you are drilling into a stud, use a stud finder to map the edges. When you drill, you will feel immediate, dense resistance and see wood shavings on your bit instead of just empty drywall dust. For ultimate safety, do a "nail test" with a tiny finishing nail to physically verify the wood before driving heavy screws.
The most expensive part of building a house is the structural shell (framing, foundation, and roofing), which accounts for roughly 30% to 40% of your total budget. However, if you categorize costs by specific line items, interior finishes (cabinets, flooring, countertops) generally represent the single largest block of expense.
Carpentry isn't vanishing, but the traditional, hands-on craft is facing an evolutionary crisis. The trade is rapidly shrinking due to a mass-exiting aging workforce, a stigma against manual labor, and the rise of prefabrication that replaces bespoke skills with mass-produced product installation.
To quickly determine if a house is poorly built, look for key structural and cosmetic red flags. Check for uneven or sagging floors, cracks around door and window frames, doors that don't stay shut, musty odors or water stains, and sloppy finishing work like misaligned cabinets or trim.
Studs in most homes are spaced 16 or 24 inches apart on center, meaning the distance from the center of one stud to the next. Interior walls are usually 16" OC, while garages, basements, and exterior walls may use 24" OC for energy efficiency.
Common stud finding mistakes usually stem from improper tool calibration, misinterpreting wall types, or relying on assumptions rather than verification. The most frequent errors include:
Yes, your phone can function as a stud finder, but with a catch: it uses your phone's built-in magnetometer (which powers the compass) to detect the metal screws or nails hidden in your drywall, rather than the wood itself.
Drywall finishers sometimes add a small amount of dish soap to their mud as an old-school hack to improve workability. The soap acts as a surfactant that lowers surface tension, which makes the mud spread more smoothly, glide easier with less drag on the knife, and helps release trapped air to minimize bubbles.
American houses use drywall (gypsum board) for interior walls instead of concrete primarily because it is faster, significantly cheaper, and provides essential flexibility during natural disasters like earthquakes. It also allows for easier electrical wiring, insulation, and home remodeling.
In the UK, drywall is primarily referred to as plasterboard.
