How many different types of Lego bricks have been produced?

I was curious and wondering: How many different types of Lego bricks have been produced since the start of the company in 1949?

• How many different kinds of bricks... or how many bricks in total? An all-time tally of all bricks ever made would probably be in the trillions. – LegoSonicBoy Dec 28 '11 at 8:05
• Edited question to be less ambiguous. – daviesgeek Dec 28 '11 at 18:14
• If BrickLink toutes already 59,338 items in its "Parts" section, how would we consider 2,200 or 4,000 or 219 even nearly in the right ballpark? – Sander Verhagen Apr 26 at 6:08
• I think that all the other answers are wrong since BL holds nearly 60,000 parts in its inventory and yet we say that 2,200 or 4,000 is right when it's not, as @SanderVerhagen said. This question is impossible to solve, and even if we say that 59,338 elements were made since we rely in BL, then we would still be somewhat wrong! There has to be some moment in history where BL messes up, no one is perfect!! I think this question should be closed!! – mindstormsboi May 22 at 11:11
• @SanderVerhagen We are looking for types of bricks. The 60,000 BL parts are not types. This similar question from 2016 asked for "shapes" which can mean "types". One example: Today, there are more than 4000 different minifig torsos in the BL part list (1 type, 4000 print patterns). So, 2000 to 4000 might even be an upper estimate for 2011 (the year of this question). It definitely is the right "ballpark". – Aziraphale May 26 at 19:20

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, Clikits, or Bionicle etc, etc, are included in that count.

`````` How Many Different Types of LEGO Elements Exist?
2,200 different elements—or types of pieces

How Many LEGO Elements Are Manufactured?
Approximately 19 billion each year
or, 2 million per hour
or, 36,000 per minute

• Where did you find that number? – Ambo100 Dec 28 '11 at 21:40

One source I found mentions that there are around 4000 different LEGO elements:

There are now around 4,000 different elements, as they are called at LEGO: round bricks, square ones, wheels, gears, and bricks with and without knobs.

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):

219

But it didn't list the many series under Bionicle, so let's bump that up to:

234

I really have no idea how our good friends Abdel and Stackings managed to get into the thousands.

• You are answering the question "how many Lego themes have been produced", not "how many Lego brick types/shapes have been produced. – htmlcoderexe May 28 at 13:41
