Common measurements in Unreal Engine 4

When you work on any game engine, it is very important and useful to know the common measurements that are used in your game world. Each game is different, and the scaling of that game world will be different depending on whether or not the developers are going for realistic scaling measurements, but for the purposes of this book, the following measurements will be for a game world that is going for realism. Remembering that by default, 1 uu is equal to 1 cm in Unreal Engine 4, here are some of the common measurements that you can implement in your game world. An additional note is that all the following dimensions are set under the assumption that your player character is roughly 6 ft tall or 180 uu.

The dimensions of a player character are 180(uu)H, 60(uu)W, 60(uu)D. These are dimensions for a larger character that is roughly 6 ft tall, so you may need to adjust these values accordingly based on your character's height.

The wall height is 300(uu)H to 400(uu)H. A value of 400 uu will produce a slightly taller wall, whereas a value of 300 uu will result in a slightly shorter wall, but any value between 300 uu and 400 uu will work just fine.

The wall depth (thickness)is 10(uu)D to 20(uu)D. The value of the wall thickness depends greatly on the material that the wall is made of. For example, a brick wall would be thicker than a wall made of plaster.

The dimensions of doors and doorways are 210(uu)H – 230(uu)H / 110(uu)W – 140(uu)W. The value of the door and the doorway depth (thickness) depends on the value of the wall thickness.

Staircases

  • The step height is 15(uu)H
  • The step length/depth is 30(uu)D

The value of the staircase width will depend on the area that the staircase is placed in, so the dimensional measurement of width will vary. The following image has a step length of 30(uu)L, a step height of 15(uu)H, a step width of 200(uu)W, and 20 steps in total:
