what is the real length ratio in planet coaster 2

The most likely answer is that Planet Coaster 2 uses a 1:1 scale for real- world length, so 1 meter in-game is meant to represent 1 meter in real life.

What players are reporting

• A Reddit post specifically describes using a 1:1 scale approach , saying 4 meters in the game corresponds directly to 4 meters on the map.

• A Steam discussion suggests coaster length calculations may be buggy in some campaign or prebuilt coasters, which can make the displayed length look wrong.

• That means the in-game length number may not always match what your eyes expect , especially on mission or preset tracks.

Practical takeaway

If you’re asking about building scale, the working assumption is real-world 1:1.

If you’re asking why a coaster “feels” longer or shorter than its measured length, the community reports indicate the length readout can be unreliable in some cases.

Example

A coaster showing 268 m in a campaign setup may still look longer in practice, because players have reported the length counter not updating correctly after edits.

TL;DR: Planet Coaster 2 appears to aim for 1:1 real-world scale, but some length calculations seem buggy, so the displayed track length is not always trustworthy.
