Question: how big are lego blocks?
Answer: The height of a LEGO brick is around 9.6 millimeters. The length and width of a 1x1 LEGO brick are 8 millimeters, which means that for every additional part of a brick (e.g. 2x1), every part adds up 8 more millimeters, which means that the width is 16 millimeters and the length is 8 millimeters.
