World Size

Upon creating a new world, player is given a choice between 3 world sizes: Small, Medium and Large.

Small - 4300 blocks wide and 1200 blocks high, sky limit about 360-370 blocks above underground level.

Medium - 6300 blocks wide and 1800 blocks high, sky limit about 450-600 blocks above underground level.

Large 8400 blocks wide and 2400 blocks high, sky limit about 800-900 blocks above underground level.

Underground level being a level where transition between dirt backround that can be removed and dirt/rock backround that cant be removed happens.

Sky, ground level, stone layer and underground layer (underground jungle being part of it) seems to be affected the most from the scaling, while size of the dungeon (not counting the corridor leading down) and underworld (always at 180-200 blocks from the lower border of the world) seems to be affected only slightly. Depth of the corruption chasms also affected only alittle bit, with a small chance of spawning a chasms down to the underground level, no matter how deep it is.

It also seems that in larger worlds resources are much more dispersed apart from each other than on the smaller ones, which means that in smaller worlds resources are much easier to locate and mine - see the mapviewer fragments for comparison.

Shots were taken from the zone 600x450 blocks at corrupted area for better comparison.
