The units in OpenSim are generally interpreted as meters, so a normal region would be 256x256 meters. Terrain textures can be any size that can be uploaded, typically they range anywhere from 4x4 to 2048x2048 pixels and both dimensions must be a power of 2. There are 4 textures for a given region terrain and regardless of size they will repeat every 7 meters or so (I can't remember the exact repeat number). They also blend according to height and some random noise.
