ArmA 3 Terrain Grid and Cell Sizes

This page is “modular” or “inheriting” so first you must read arma terrain grid and cell sizes page to know the background and other sizes than listed below.

What size is your terrain? How to describe it on forums / chats? What size are official bis terrains?

New capability in ArmA 3 is that it / terran builder now supports 8192 grid heightmaps. Note: 8192 grid heightmaps make terrain builder extremely unstable (freezes or even crashes are normal behavior), it is not recommended to be used unless you are experienced terrain developer.

Do NOT use 8192 grid heightmap!

Grid Size Cell Size Kilometer x Kilometer
8192 50 409.6
8192 40 327.68
8192 30 245.76
8192 20 163.84
8192 10 81.92
8192 9 73.72
8192 8 65.53
8192 7 57.34
8192 6 49.15
8192 5 40.96
8192 4 32.76
8192 3 24.57
8192 2 16.38
8192 1 8.19
8192 0.5 4

Do NOT use 8192 grid heightmap!

The km x km is the standard we have used since 2001 OFP era. To explain your terrain size use “km x km” or just “km” for example “40km terrain” to keep it simple. Never use any other odd mumbo jumbo value system.

Some terms for below table:
Satellite Tile is NOT satellite “texture”, it is the TILE to which satellite texture is chopped. These tiles can be found in Layers\ dir as *.paa files.
Texture Layer is internal WRP tech which is complicated to explain and basically is useless info in this pages context but we added it to be thorough.
