The grid in every Gather Space consists of 32 by 32 pixel squares that we refer to as tiles. When moving around a Space, your character will move  on to and occupy entire tiles.  When placing objects, they will snap to the existing grid both in the Mapmaker and Builder Mode and so designing a space in multiples of 32 pixels with particular junctions lining up with the 32 pixel grid is recommended.

In designing your own Space, you need to consider facilitating interactions as well as free movement. You can connect with and communicate with someone who is roughly 5 tiles away from you in any direction. Audio and video is most clear when 2 or less tiles away from another person with a gradual fade such that, at a distance of 6 tiles, you are no longer connected. Ideally every person should have the option to remove themselves from the conversation. Taking this into account, when you size your map,  we recommend:

  • a max of 3200 x 3200 px dimensions (or 100 x 100 tiles). 
  • background image file size should be less than 3 MB.
  • plan at least 20 and 40  available tiles per expected guest (roughly 5 by 5 tiles for a 25-tile-square per person)
  • use an odd number of tiles (to help easily divide your Rooms into smaller sections or have a centerline to focus your Rooms around)
  • size your default entry Room or area to the max rate of expected guest arrival per 5-minute interval

You don't want your space to feel so large that you could go days without running into another human, but you also want to allow for enough room such that any one person is not forced into conversation if they do not wish it. 


For a 200 person event, you would want a map that with roughly 4000 to 8000 tiles (200 people times 20 to 40 tiles per person). 

Let say you settle on 5000 tiles. You can accomplish this with:

  •  one large room map of 51 x 101 tiles (1632 x 3232 pixels) 
  •  one large room map of 51 x 51  tiles (1632 x 1632 pixel) and two smaller side room maps of 25 x 51 tiles ( 800 x 1632 pixels)
  • Or any combination thereof

You event has some arrival flexibility, but you're also having a keynote speaker at a very specific time. You decide you want to open the space roughly 30 minutes before the talk and expect that roughly half of your attendees will arrive 10 minutes before the talk. This gives a very rough estimate of 50 attendees per 5-minute interval.  You can determine the minimum size of your default entry room or greeting area in the following way:

  • 50 attendees x 25 tiles = 1250 tiles square. 
    • square root (1250) ~ 35 tiles --> Default Entry Room / Greeting Area ~35 x 35 tiles (1,120 x 1,120 pixels) 
    • Or to use easier numbers: A Default Entry Room/ Area of 25 x 50 tiles (800 x 1,600 pixels) +/- one tile to make it odd and easy to divide

These are all recommendations and are not hard and fast rules. If you find that you like to subdivide your spaces into smaller areas, you may want a larger map to accommodate the additional walls.

How Big Should I make my Spawn Tile Area?

For information on how to size your Spawn Tile Area within your Default Entry Room/ Greeting Area to maximize your guests' experience upon first entering your Space, please click here see our article on Spawn Tiles.
Example of spawn points split between entrances. This example would accommodate a rate of 36 "simultaneous" guests.
