900 or 1200 mm drywall?

I suggest horizontal raw plank with vertical 1200 gypsum on the outside.

1200 and staggered seams.

Why would you have different panel sizes, do you think?

What kind of room is it? You can manage perfectly fine with OSB. The difference is more in price than in tensile strength between OSB and plywood.

Ahh ok. So 1200 for both plywood and plasterboard 👍👍
The room is a regular interior room. So OSB might be enough then? I've heard that plywood is supposed to be much better.

That's a myth.
Buy plywood if you want, I find it hard to see that you'll regret it if you choose OSB. 👍

I was also thinking about doing something similar in the garage. It's a cold garage, but about 1/5 of it is sectioned off as an insulated storage room. I was thinking of taking down the existing gypsum wall and only replacing it with plywood or OSB. Is that okay to do, or do you have to use gypsum as well?

I was thinking of doing something similar in the garage. It is an unheated garage, but about 1/5 of the garage is partitioned off as an insulated storage room. I was thinking of taking down the existing gypsum wall and only replacing it with plywood or OSB. Can you do that, or do you have to also put up gypsum?

You can do that.
But if you still plan to have plywood or OSB on the outside, you could mount it on top of the gypsum.

I was actually thinking of doing something similar in the garage. It's a cold garage but over 1/5 of the garage is divided into an insulated storage room. I was thinking of taking down the existing drywall and only replacing it with plywood or alternatively OSB. Can you do that or are you required to also install drywall?

Drywall is good for reducing the risk of fire spread.

Gypsum is good for reducing the risk of fire spreading.

But is it a requirement? It would be nice to avoid hanging gypsum, spackling, sanding, and all that follows 😮‍💨

Puttying and sanding are optional, you can probably have the drywall as it is or just painted with a simple color if you wish.

Filling and sanding are optional, you can probably leave the plasterboard as it is or simply paint it with a basic color if you wish.

Ahh true that
