Large Biome worlds are generated as Default worlds, but have 16 times as much area (multiplied by 4 along the X and Z axis), causing the biomes of the Overworld to be expansive. A Default and Large Biome world sharing the same seed are geographically the same, overall. Rivers are not larger than they are in a default world.
The player can use a map to gain a visual representation of the scale of the biomes in their world.
Large Biomes offer a play experience different from regular sized worlds. If a player starts in an undesirable area, such as a desert, it can be difficult to survive. The generation system also leads to rare biomes being far more difficult to come by, but with more valuable resources when they are eventually found (for example, woodland mansions are more likely to spawn in dark forests that are sufficiently large).

- In Java Edition 1.18, the scale of biomes can be altered through the
biome_sourceof Custom worlds. Decreasing each
firstOctaveby 2, roughly makes biomes have a similar size to Large Biomes. [needs testing]
- Amplified - Similar to large biomes, but world generation is instead expanded vertically.
