Installing indoor paneling, spacing between studs?

[Rode]

We are going to install paneling on a concrete wall at home. First battens, then we're planning to put up cladding boards. 95mm, 120mm & 145mm wide. What can be the center-to-center spacing for the battens? The only thing going up on the wall afterward is some pictures and similar items. Can we go over 100 in cc?

If you mean regular cladding boards that are about 20-22 mm thick, you can probably get by with cc1200mm. But I would have framed cc600 to be on the safe side. Not because it wouldn't hold the paintings, but to avoid the risk of the wall bulging.
