Dear Anna, if you do this in Germany (as we did with the 2108 in Würzburg) you need to deal with the fire department ... and every one of the 16 states has different rules. Usually, you are limited to 199 chairs that you can place any way you like in a room. If you have more, the exact floor plan with the circles and all needs to go through an administrative process... usually (always) the people in the venue know about this. If you have more than 199 chairs, the chairs need to be either bolted to the floor are hinged together, mostly in bunches of 5.
In Würzburg we got around all of this by getting 2108 pillows in I think 13 concentric circles... the were then also used by participants for breakout spaces, massage areas, napping spaces ... etc. For the geometry itself you got a large number of highly professional pointers alreadd, I just want to add Start with the inner circle and have it be a really perfect circle. S.H. (something happens OR selforganisation happens) when the circle is perfect. Do you remember the situation in the Moscow WOSonOS a few years ago when things were simply perceived as pretty awful by the facilitator (I think it might have been Raffi) and he asked one of the seniors of OST present (I am sure it was Birgitt Williams) what she suggests we should do. She got up and asked very one in the room to grab their chairs and make a perfect circle of what actually was a pretty messed up circle. Folks followed her suggestion, got up, created a perfect circle, sat down and then instantaneously mega S.H. hugs mmp PS: Go to this very long link to get more details on the Würzburg event

Thanks Harrison. In my experience, two meters is fine to pass behind the rows on your way to the agenda wall, but it is not enough when you have 300 people in front of the agenda wall trying to figure out where they want to go. You don’t want people tripping over the empty chairs that are in the way. So directly in front of the agenda wall, I would allow for at least 6 meters (20 feet) if you have 300 participants. Good luck Anna Carolina!

I do love this! And Koos – your spread sheet is fabulous!! Frankly, I’ve found that the basic “rule of thumb” – take the rated room size and divide by 2 -- will get you started. (A room rated for 300 will work well for an Open Space of 150)... and from there on out you just have to go with the flow. Remembering: 1) Have as much space in the center as you can, so folks aren’t all crowed together. After all this is OPEN Space. And 2) Leave a meter or two (3-6 feet) between the last row and the Wall so that folks can easily post their issues. Congestion slows everything down. After that, anything will work. Or more to the point, the people will figure the way. And do have fun!
