Map Sizes

If a small map is 1 unit square...

• A medium map is 2 units square
• A large map 3
• An extra-large map 4

Tile dimensions

Note: you can't multiply rows by columns to get the area of the map, because the corners of the grid are cut off; see Coordinate System. The actual area of the map is 1/2 × rows × cols

• Small: 76 × 76
• Medium: 152 × 152
• Large: 228 × 228
• Extra-large: 304 × 304

Such odd numbers, aren't they? But that's what they are. I'm guessing they started with 75 × 75 and then decided they'd better make it an even number.
