Map sizes
All eight map sizes, heightmap resolutions and how to unlock the larger experimental maps.
Transport Fever 3 publishes eight map sizes across five aspect ratios: 1:1, 1:2, 1:3, 1:4 and 1:5. The official manual defines the ratio using the lengths of the map edges. Read each row as one named size and each column as one shape. Both tables below reproduce the published values, so you can compare the physical dimensions and the heightmap resolution for the same selection.
Small, Medium, Large and Very Large are available without enabling experimental features. Four other names carry an asterisk: Tiny, Huge, Megalomaniac and Gigantomaniac. Tiny is the smallest experimental choice, while the other three extend beyond Very Large. The asterisk therefore identifies a setting requirement rather than simply identifying the largest maps. All eight game names remain unchanged here so that they match the manual.
The first table gives edge lengths in kilometres. For example, the square Tiny map measures 4.096 × 4.096 km, while the square Gigantomaniac map measures 28.672 × 28.672 km. At the 1:5 ratio, Gigantomaniac is listed as 12.800 × 64.000 km. These figures describe the sides of the map. The game rounds displayed values, so use the manual’s dimensions when comparing the entries below.
The second table gives heightmap dimensions in pixels for the same eight names and five ratios. Find the same row and column in each table to read the two published measurements together. Keep the units separate when comparing them: kilometres describe the map edges, while pixels describe the heightmap. The entries are transcribed as published, including repeated dimensions in the Tiny row.
Map size is also a hardware choice. The manual connects map size with the amount of RAM needed and, in most cases, the CPU power needed as well. Smaller maps tend to run more fluently. Experimental sizes require at least 16 GB RAM. Check this requirement before choosing an experimental entry; the setting that exposes those sizes does not remove the memory requirement.
The Console Edition has a separate restriction because of memory limitations: only Small, Medium and Large are available. For the experimental setting, the manual describes editing settings.lua in the userdata folder with the game closed. The instructions below explain that switch and the associated economy warning. Consult the linked manual for the source tables and compare the system requirements before deciding which map size to use.

* Requires experimental map features. Tiny is smaller than Small; the other three marked sizes are larger than Very Large.

Use the same size and ratio as in the dimensions table. These are the heightmap resolutions published by the manual.

* Requires experimental map features. Tiny is smaller than Small; the other three marked sizes are larger than Very Large.
Enable experimental map features
The switch is in settings.lua inside the userdata folder. It unlocks the four sizes marked with an asterisk in both tables.
- Close the game before editing settings.lua.
- Find experimentalMapFeatures and change its value to true, as shown below.
- Save the file and restart the game.
experimentalMapFeatures = true,Experimental map sizes require at least 16 GB RAM. Larger maps need more memory and usually more CPU power; smaller maps tend to run more fluently.
This flag also enables changing the economy in an existing savegame. The manual warns that doing so may lead to unstable situations.
Console map size limit
Due to memory limitations, the Console Edition only allows Small / Medium / Large.
