Wired Science published a ridiculously detailed statistical analysis of the size of LEGO blocks in an article titled “Why Are LEGO Sets Expensive?”
I’m not sure I would say LEGO blocks are that expensive, but the statement is that they are expensive because they are so well made. Really, this has to at least be partially true. If you take some blocks made in 1970, they still fit with pieces made today. That is quite impressive.
But the real question is: what is the distribution of LEGO sizes? How does this distribution of sizes compare to other toys? The simple way to answer this question is to start measuring a whole bunch of blocks.
Incredibly nerdy but fascinating to read.
