Ceiling joists are usually installed either 16 or 24 inches on center, which means roughly 16 or 24 inches apart. Once youâve located the first one, the others are easier to find. If you only need to know which direction the joists run, access the attic and take a look.. Use the tape measure to map the rough location of the next joist, roughly 16 or 24 inches away from the first, and tap the ceiling with your knuckles or sweep a stud finder over the area to pinpoint the joistâs location.
These are usually placed 16 inches from centers, except for floors which are to carry very heavy weights. In these the joists are frequently placed 12 inches from centers. To estimate them 12 inches from centers add 1 to the number of feet in length of one wall on which the joists are placed.For example, suppose a building is 32 feet long, and the joists are placed 12 inches from centers.We simply add 1 to 32, which makes 33 the number of joists required for one span.f the spans are unlike, then estimate each span separately. If the joists are placed 16 inches from centers, then multiply the length of wall by Â½ and add 1. This will give the required number. Thus if the wall is 32 feet long, then 32 x Â½ + 1 = 25, he number required for one span.
