I was curious and wondering: How many different types of Lego bricks have been produced since the start of the company in 1949?
One source places the number of different types of LEGO elements that have been made at 2,200. It is unclear whether or not DUPLO, Click-its, or Bionicles etc, etc, are included in that count.
One source I found mentions that there are around 4000 different LEGO elements.
This link gives a list of every official theme and type up to now. These themes include DUPLO, Bionicle, Znap, and Baby, among the many other wonderful adventures LEGO has offered over the years!
So I counted them one by one. It was tedious. Total listed (spoiler):
But it didn't list the many series under Bionicle, so let's bump that up to:
I really have no idea how our good friends Abdel and Stackings managed to get into the thousands.
