Instead of locating the floor joists by sound, you can use a stud/joist finder designed for floors. Simply turn the device on, place it on the floor and move it to the left or to the right until it lights up. Do not use a standard wall stud finder on floors, since the readings will not be accurate.
How far apart are joists in a floor?
Most often, floor joist spacing is 16 inches apart on center, but this can vary depending on building codes and the requirements of the structure in the blueprint. Floor joists help distribute the load of a structure.
Where is a joist found?
A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm.
Do all ceilings have studs?
You find studs in the walls and joists in the floors and ceilings. However, they are very similar, and you can use a stud finder to locate a joist. Ceiling joists are always the same distance apart. The spacing will be either 16-inches or 24, and it will be the same everywhere in your home.
What is the difference between a stud and a joist?
You need to find studs in order to securely hang pictures, mirrors, shelves and more on the wall. Joists are the support beams in your floor and ceiling. You need to find these if you want to hang light fixtures, ceiling fans or fix squeaky floors.

How far apart are floor joists in old houses?

Are joists load-bearing?
Located between walls, beams, and foundations, floor joists are structures that support floors and most easily identified in a building’s basement or attic. Walls that run parallel to joists are not typically load bearing, whereas walls that run perpendicular to the joists are most likely load bearing.
