I'm using a stud finder to find studs behind dry wall and so far I've found 2 and they are 16" apart. Does that mean that there will be a stud every 16" or might the distance change between studs? Is 16" the standard for stud centers?
Yes, in most US residential construction they are 16" center to center. Most of your standard tape measures have every 16th inch noted in red or some other way. Some internal walls may also be spaced 24" on center.
However, there may be exceptions where a door window or odd length wall is used so be sure to verify with a stud finder or a knock on the wall to check.
In Australia there are two standard widths for studs. 60cm (23.6") and 45cm (17.7").
Builders will stick to that whenever they can, but if they need to move them or add new studs for, say, structural reasons, they will. I would never ever make assumptions regarding the locations of studs.
What I would do is use the knowledge of your local stud standards to help me find the next stud.
Not sure what other nations standards are for stud distances.
There are at least 3 standard spacings, all based on an 8 foot (96" unit)
- 16", 6 studs per 96" (usually in red on a tape measure)
- 19.2", 5 studs per 96" (and there is usually a little diamond symbol on tape measures for this spacing)
- 24", 4 studs per 96" (most tape measure makers think you can handle this one without additional help)
Due to door (frames), window (frames), plumbing, ducts, and wall-lengths, spacing may not be completely uniform.
This depends on whether it is a load bearing wall and what you are using for studs. In a load bearing wall they are normally 16in on center. In a non-load bearing wall they can be 24in and if using 2x6's they can be wider apart as long as plate and/or rafter tie-ins are used and exterior or interior sheathing, not drywall, is used to stop horizontal shear and the rain/snow load is taken into account. These widths make it easy to use 4x8 plywood or drywall for covering. In the southern United States, where you do not have a snow load, you can get away with 24 inches with the sheathing for garages but for a domicile I would use 16in in all applications.
I have a wall that is just under 11.5'. The door takes up 32". The studs from the door frame to the corner of the wall have varying lengths in between them. Spacings: 7.25", 13.5", 26.5", 19.5", 19" and 18.5". This is measuring from the approx center of each stud. This wall is made of Drywall. And, these are crazily spaced! Nothing about the room/wall really leans toward an answer to why. Therefore, What the people said above is true: "The standard is usually 16" or 24" between studs, it can vary depending on the construction". So, the best way is to tap/knock on the wall where you know a stud is, and compare that to the rest of the wall. All the while using a tape measure to test 16/24" lengths.
