The dimensions of LEGO bricks are based on a modular system with a fundamental unit of 0.8mm. This base measure, along with play measures and stud height, dictates the overall size and compatibility of LEGO elements.
While a complete list of every LEGO brick dimension is vast, understanding the underlying principles provides a clear picture. The following points highlight key aspects of LEGO dimensions:
- Base Unit: 0.8mm. All LEGO brick dimensions are multiples of this base unit.
- Play Measure: An additional 0.1mm is added as a tolerance, or "play measure," to ensure bricks fit together easily.
- Stud Height: 1.8mm is the height of a LEGO stud.
Therefore, the dimensions aren't single set values, but rather values derived from these key measurements. A 2x4 brick's length and width are based on multiples of 0.8mm, and the height incorporates the stud height and the thickness of the brick's base.
Because the size of LEGO bricks depend on the number of studs on top, it is impossible to give dimensions without specifying the exact brick. However, using the information above you can determine each dimension if you know the stud number.
