Standard rules for interior wall?

[JonasHolm]

Hello!

What is the standard dimension of studs for non-load-bearing interior walls?

I thought that 45x70 was used... Is that correct, or is it 45x95 that's used?

You can use 45x70. But in my opinion, it looks a bit "risigt".

We go with 145 all the way through. But that's only about the appearance of the walls, not their strength.

If space is limited, maybe you should go with "klena" walls, but if you have extra space, I think you should go with thick walls.

I'm not a carpenter, but I think 45x70 is enough..

70 studs are most common for interior walls. 95, 120, and 145 are used if you want a better sound class or if it's some form of load-bearing wall or if you like thick walls...
Standard does not exist but as mentioned 70 is the most common

If you want to soundproof, you should not increase the frame dimension. Either you add double layers on the wall with plasterboard/chipboard, or if that's not enough, you build two thin walls next to each other. For example, 45X70 air gap new 45X70. This dampens significantly more than more insulation unless the insulation is special insulation designed specifically for soundproofing. To achieve good soundproofing, I make a strong simplification and say that the wall should be heavy and consist of several different materials.

I was thinking of building the wall roughly like this...

Gypsum - Chipboard (or OSB) - Stud - Chipboard - Gypsum.

Maybe the thickness should be increased on at least some walls considering the sound insulation...

if the sound you have in mind is better with

Gypsum - Gypsum - Chipboard (or OSB) - Stud - Chipboard - Gypsum - Gypsum

where you mount the plasterboards staggered

If you want to soundproof, you shouldn't increase the frame dimension. Either you put double boards on the wall gypsum/chipboard, or if that's not enough, you build two thin walls next to each other. For example, 45X70 air gap new 45X70. This dampens significantly more than more insulation, as long as the insulation is not special insulation intended specifically for soundproofing. To achieve good soundproofing, I'll make a strong simplification and say the wall should be heavy and consist of several different materials

What I meant by higher sound class is that with more distance between the boards, you get a better lowest frequency in the wall. You also get better sound insulation due to the distance between the masses.

And if you want a sound class, you skip the chipboard and use 3 layers of gypsum double studs, and so on... But that's another story... Stud walls within the same residence with more than 40 dBA R'w are pretty much ridiculous. You achieve this with 70 studs, 30 mm insulation, and 2 layers of gypsum. If you choose to replace 1 layer of gypsum with chipboard or another wood material, you get around 36-38 dB sound insulation... If you have the same construction with 95 studs, it is rated at 44 dB.
