User blog comment:Clawson263/Hey guys what world size do u like better Small Medium or Large?/@comment-1466854-20131203091448

Large for multiplayer worlds (more space to spelunk and build incessantly without crossing paths, more space for multiple full castles/mansions/etc).

Small for singleplayer worlds generally. Small worlds tend to have a tighter clustering of resources, much easier to get what you need faster, more than enough space for a single player's buildings and such. They also load up much faster, which matters when switching worlds frequently or otherwise loading often. Worth note, I do use -multiple- small worlds for my singleplayer experience.

Medium... is just odd. Too large for singleplayer, too small for multiplayer, I haven't really bothered with these much.
