[UE5.8] Recommended room and living room dimensions for a first-person horror game?

Hello everyone,

I am planning to create a short, 1-hour first-person horror game in Unreal Engine 5. The player will control a character exploring a dark house using a flashlight.

Since my main character is 175 cm tall, I want to make sure the environment feels realistic yet comfortable for the camera and player movement.

I would like to know what the recommended dimensions (in centimeters/Unreal Units) should be for the rooms in the house? Specifically, how big should the living room be to feel atmospheric and eerie without causing camera clipping issues?

Any advice on modular wall heights or hallway widths for this type of horror game would be greatly appreciated!

Thank you!
