Out of curiosity: How long can a 1×x brick be?

When there are differences, I can think of the following categories:

  • Longest brick ever included in a regular Lego set
  • Longest brick ever available through other channels
  • Longest brick produced ever and visible on exhibits or other occasions, but unavailable to the public

EDIT: I am only interested in bricks made by LEGO, clone brands do not count.

  • Within bricks, do you include plates and tiles? – Craig Aug 6 '19 at 23:48
  • No, this is another question to be asked. – jk - Reinstate Monica Aug 7 '19 at 8:46

If you mean specifically Lego bricks, I'm pretty sure the 1x16 was/is the longest one made. Outside of the 1x? sized bricks, the longest plain shaped brick that I know of is part #30072 or #47122 at 24 studs long. I don't know about other brands though.

  • Yes, I mean LEGO specifically, I'll add this to my question. – jk - Reinstate Monica Aug 5 '19 at 11:02

You didn't say anything about modified 1 x bricks.

  • This is Item 47978 and it is actually listed as a 2x24 brick, because of the added bit in the middle.

    Still technically a 2x though :P – JohnnyB Aug 6 '19 at 0:26

This technic rack is 1x20 and is exactly 1 wide, no hanging out bits

    Ah, nice find! I wouldn't consider it a brick though being only 2/3 the height. – JohnnyB Aug 6 '19 at 0:25

    And no studs, unfortunately. +1 for this nice find, anyway. – jk - Reinstate Monica Aug 6 '19 at 9:12
