World size

Map Size refers to the size of a Terraria world. Upon creation, you can select either "small", "medium", or "large" for the size of the map you generate.

Dimensions of the different map sizes are as follows: (one block = two feet)

Map Size Comparison
Different world sizes may be better suited for different purposes. Players may find that creating many small worlds may be more efficient than creating large worlds due to the amount of memory needed.

Advantages of Small Worlds

 * Getting to specific locations like the Dungeon, Jungle and Oceans requires less walking
 * Less digging is required to reach the Underworld
 * Floating Islands are lower and therefore easier to find
 * The world saves and loads faster

Advantages of Large Worlds

 * There is more space to build and explore
 * There are more total chests and pots underground per world
 * There are more floating islands
 * The Dungeon is larger
 * There are more Corruption chasms
 * The Underworld is larger, potentially giving more time to defeat the Wall of Flesh
