How Many LEGO Bricks Can Be Stacked?

Published in LEGO Physics 2 mins read

A single LEGO brick can theoretically support approximately 375,000 identical LEGO bricks stacked on top of it.

Here's the breakdown of how this number is derived:

  • LEGO Brick Mass: An average 2x2 LEGO brick weighs around 1.152 grams.
  • Maximum Load Capacity: A single 2x2 LEGO brick can withstand a mass of approximately 432 kilograms before being crushed.
  • Calculation: Dividing the maximum load capacity (432 kg) by the mass of a single brick (0.001152 kg) gives the approximate number of bricks it can support: 432 kg / 0.001152 kg/brick = 375,000 bricks.

Important Considerations:

  • This is a theoretical maximum. Real-world factors, such as imperfections in the bricks, uneven weight distribution, and environmental conditions (temperature), could reduce the actual number of stackable bricks.
  • The type of LEGO brick also matters. Larger bricks might have different load-bearing capacities. The 2x2 brick is used for this calculation as it is a common and recognizable size.
  • The orientation of the brick and the way the load is applied affects its strength.

Therefore, while a LEGO brick is remarkably strong for its size, stacking 375,000 bricks in a stable and practical structure is highly unlikely. It is more of a theoretical limit illustrating the material strength.
