Max room size

[POMF POMF]

What is the max room size before you can't build a roof?

There's times I build a room and it ends up being "too" big and it all gets roofed except one small block and I have to place a wall in the center.

What room size do you recommend for like storage etc?

I think you just need to build some support columns.

yea I at the time had to build a single wall/block in the center to get a roof placed there.

But I'm wondering how big until the roof can't get placed.

A roof will collapse if it is more than 6 spaces away from any support structure.

Ah okay I see now

11x11 is the maximum, you need to build supports for anything bigger.

ah I usually make store rooms 10x10

12 across is actually the maximum. You can run 12xWhatever and it will stay up.

But you shouldn't necessarily use that, because the bigger the room the more likely you are to have a collapse if walls fall in a fire or a raid. Plus, for storage rooms, a 12x12 doesn't quite fit the shape of a trade beacon.

I often make storage rooms the shape of a trade beacon, and just put in the necessary supports.

Oh right.

If you use even amounts of tiles.

This mod is pretty nice.

I have difficulty convincing the game to put a roof on anything larger than 128x128, even when there are suitable pillars for the roof.

Without pillars? 12x12 floorspace, which is 14x14 walls.
Make it even 1 bigger and you need *multiple* support pillars.

My storage rooms are 15x15 floorspace with the trading beacon in the center and only one support pillar right next to it

[Slye_Fox]

I generally make my rooms 13 across(including walls) so the centre tile get's support from both sides.

you can make:
12xA of space (with 14xA walls), A - any number.
21x21 space (23x23 walls) with 1 cell wall at the center
21x42 space with 2 walls at centers of both 21x21 squares (any 21xA*21 works).
Any square of space bigger than 21x21 requires at least 4 additional walls inside.

You can check the maximum area of roofing that can be placed around a single support here

Without support columns, 13x13. At least from experience and with support columns, as big as you wish.
