So I took the blast zone information compiled by Ruben and created a chart:

Some interesting takeaways:
- Ceilings are either in the 180 club or the 192 club with the exception of T&C, WarioWare and Halberd. Halberd ironically enough has the highest ceiling in the game for a potentially legal stage.
- The longest legal stage in the game is Mushroomy Kingdom U for Doubles, followed by Pokemon Stadium 2. The Stadiums in general have long floors.
- Mushroomy Kingdom U has reasonably normal blast zones, so it isn't too large there. However along with having the longest floor, it has close blast zones from the ledge, though not as close as WarioWare. Probably fine for doubles.
- While WarioWare has narrow blast zones it also has smallest stage floor with the exception of Brinstar.
- Nothing ever exceeds 500 units across from left to right blast zone.
- Not only are the blast zones narrow on WW but spiking people for kills is stronger.
- Out of all the triplats available, Yoshi's Story is by far the most distinct from Battlefield. It is the only one in the 180 club for ceiling height as opposed to 192, making it the Dreamland of this game. It is also the easiest to spike on, has the narrowest blast zones, and has the shortest floor. It is not as small as Melee's Yoshi's Story, but it is the smallest variant here.
