Studs for interior wall

[Nene]

We have demolished an interior wall made of blue concrete for radon remediation purposes. The wall was approximately 100 mm thick. The replacement wall should preferably not exceed 100 mm. I am planning to use 45 x 45 mm wooden studs with a 60 cc spacing, then screw in 11 mm OSB, followed by 13 mm gypsum. This totals 93 mm. Now to the question: is it okay to use 45 x 45 studs (the standard is usually 45 x 70)?

For a non-load-bearing interior wall, it works perfectly fine.

Thank you, then it's Byggmax next.

A tip is to use 45x95 or 45x70 flat instead of 45x45. The wall will then build just as much but will be much stiffer. But as JanneL says: It's enough. And if you have osb behind the plasterboard, it might be stiff enough anyway.

Good idea with 45x70. More margin for the screw row as well.

Yes, 45x45 and double layers of pbs sheets will probably be super sturdy; I doubt anyone will notice that it's 45x70 instead. But as a little "wiggle room" when screwing, it might be a good idea. An even better advantage is that it increases the chance of finding one or several studs when you're mounting something really heavy.
