    I have quite a few stud walls to build, they are not supporting anything.

    All the sites say to use either 400 or 600 centres (depending on the thickness of the plasterboard). They go on to say to use 2x3 or 3x4 but do not say when one should be picked over another.

    CLS is quite heavily cut to size leaving 38 x 63 and it seems very small, or is it strong enough? Does the height of the ceiling have an impact, if so at what height do you have to increase the size of the studs?

    Thank you for your help.

    CLS we get generally comes as nominal 3 x 2 (44 x 70), undersize 3 x 2 (38 x 63) or 4 x 2 (90 x 44). The thickr stuff is more rigid and certainly necessary when erecting stud partitions such as those you'd put up in a Victorian office, at say 4.5 to 5 metres. At that height the wall would probably be a bit "floppy" with 3 x 2s. The deeper section also allows for sound insulation (mineral wool) to be installed inside the core. The really small stuff is absolutley horrib;e and I normally wouldn't want to use it on anything other than very small scale jobs (e.g. closing off an understairs space). In answer to the question - I tend to use 4 x 2 if possible when the ceiling is much over 8 feet (2.4 m) high, if glazed panels need to be inserted, if heavy loading (e.g. stock shelves) will be placed on it or if mineral wool sound insulation is required

    Thank you JobAndKnock, the highest ceiling is 2.4m high and 4m long for the hallway so no insulation required.

    Insulation is mainly for reducing sound transmission.
