To restate the strength conclusions, 2x6 studs are great at 24-inch spacing, plenty strong even up to 10 feet long, supporting several stories. However, you have to be careful with 2x4s – they can make it at 24 inches but with restrictions.

For panels used as base for spray-applied ceiling texture finish, maximum frame spacing is 16 inches on center for inch thick panels perpendicularly applied (parallel panel application not recommended); 24 inches on center for 5/8 inch thick panels perpendicularly applied, 16 inches on center for parallel application.

Accurately measure the distance between the vertical rows of the nail / screw heads found above. It will likely be 16 or 24 inches (40.6 or 61.0 cm), with the 16 inch (40.6 cm) measurement being far more common.

If all of that is framed with studs at 24 inches rather than 16, the number of studs saved will be approximately 300*.25= 75. That’s approximate because it doesn’t take into account doors and windows, but you could subtract out that lineal footage for more accuracy.

Project the stud closest to the desired location for the support of the shelf, picture, etc. Using the measurement multiple determined above, find the stud 16, 32, 48 etc., or in the case of 24 inch (61.0 cm) centers, 24, 48, 72 etc. inches away from the closest stud found-along the baseboard molding.

A 2x4 stud with the same loading as above but spaced only at 16 inches does not calc. Shorten that stud to 8 feet long and it makes it, but barely. To get a 2x4 to calc at 24-inch spacing, it can be no longer than 9 feet and support only roof load.

In the United States studs were traditionally made of wood, usually 2×4 or 2×6 dimensional lumber and typically placed 16 inches (406 mm) from each other's center, but sometimes also at 12 inches (305 mm) or 24 inches (610 mm).

First, you’ll use far fewer studs. Here’s an easy way to determine approximately how many you’ll save: number of studs saved=lineal feet of wall*0.25. As an example, say you’re building a 50-foot-by-50-foot, one-story house. The total length of exterior wall is 50*4=200 lineal feet. Let’s assume there are 100 lineal feet of interior wall.

Use the repeating measurement to help project the location of the next stud. The 16 inch (40.6 cm) centered studs will be found at 16, 32, 48 etc. from nearly any stud found. Likewise, the 24 inch (61.0 cm) centered studs will be found 24, 48, 72 etc from nearly any stud found. Places where the distance may be less than the 16 or 24 multiplier can occur at wall corners, doorways and windows.

how many inches between studs
There are 16 inches or 406 mllimetre between studs. 16 inches between studs.
