Measurements

Base sizes I use for my 15mm figures:

Infantry = 15/16" x 9/16"
Cavalry = 1 3/16" x 9/16"
Artillery = 1 3/16" x 1 10/16"
General = 15/16" x 15/16"

I play on a table size of 4' x 6'

For those who like a more metric set of measurements use:

9/16" = 15mm
15/16" = 23mm
1" = 25mm
1 3/16" = 30mm
1 10/16" = 41mm
2" = 50mm
3" = 75mm
4" = 100mm

6" = 150mm
8" = 200mm
10" = 250mm
12" = 300mm
16" = 400mm
24" = 600mm

4' = 1200mm
6' = 1800mm
