About this conversion
Re-Logic's official Terraria Wiki measures worlds in tiles at 2 feet each: small worlds are 4200 tiles wide (8400ft, 2.56km), medium worlds 6400 tiles (12800ft, 3.90km) and large worlds 8400 tiles (16800ft, 5.12km), so one large world equals exactly two small worlds.
These figures come from terraria.wiki.gg (World size page) via the in-game Compass and Depth Meter, which reveal each 16-pixel tile as 2 feet. 1 large = 2.00x small (5.12112/2.56032), 1 medium = 1.52x small, making this converter a handy reference for build planning, hellevator math and everyday curiosity.
Units supported: Kilometers, miles, feet, tiles and world widths (small 2.56km, medium 3.90km, large 5.12km).
Source note: Sizes from official Terraria Wiki — 1 tile = 2 feet; small 4200, medium 6400, large 8400 tiles wide.
