More joints, but heavier boards. I got 1200 boards for my ceiling, and
after lifting one, I changed to 900mm, using the 1200 for walls. With
assistance 1200 would be ok. 9.5mm at 2400mm board may be too bendy for
single handed fitting.

Here they use 3600 boards glued and nailed to studs/joists. Walls are done
with the boards in landscape mode so that smaller rooms have one
horizontal joint only per wall.
