At least once year, I update the Most Common LEGO Parts to reflect those parts are gaining (and losing) popularity over time. This revised analysis is based on all of the sets released so far from 2017-2021.
10 parts that caught my eye…
| Rank |

Part ID & Name |
Notes |
| 14 (+22) |
 |
25269 – Tile Round 1 x 1 Quarter |
It jumped 36th place last year and 14th place this year. The rise no doubt follows the increased popularity of LEGO Dots. |
| 9 (-3) |
|
3004 – 1×2 Brick |
The humble 1×2 is about as simple as it gets, but it has dropped three positions in the rankings in a single year…
It’s not alone; other classic bricks like the 2×2, 2×3, and 2×4 have gone down in the rankings, too. |
| 147 (-75) |
|
33291 – 1×1 Plate, Flower (4 Petals) |
Here’s a seemingly classic part that’s plummeting in the charts because it retired in 2020. By contrast, heir-apparent 1×1 w/ 5 Petals (Part #24866) rose 13 spots to 38th place this year. |
| 216 (+90) |
|
36841 – Bracket 1 x 1 – 1 x 1 |
It’s no surprise that this incredibly useful part continues to grow in popularity! |
| 240 (-43) |
|
15379 – Technic Link Tread with Beveled Edge |
The part has been common in the past, but is falling in popularity… It’s in just one set this year. |
| 283 (+129) |
|
26287 – Technic Driving Ring Connector Smooth |
Sometimes you just need a slightly longer Axle connector, or so it seems! |
| 710 (+418) |
|
66956 – Slope Curved 2 x 2 with Stud Notches |
I’m a bit surprised this part was made in the first part, since both the left and right sides exist as separate parts. Nonetheless, it’s rocketing up the charts! |
| 714 (+264) |
|
65803 – Brick Special 16 x 16 x 1 1/3 with Pinholes |
This sturdy part continues to be propelled to fame by the LEGO Art sets, including the massive #31203 World Map set. |
| 749 (+516) |
|
42918 – Slope Curved 8 x 2 No Studs |
This three year old part was used in 7 sets this year, with 24 parts in #10289 Bird of Paradise alone. |
| 917 (+384) |
|
40066 – Panel 1 x 6 x 7 with 2 Columns and Arch |
While of limited appeal to most AFOL’s, this three year old part is being widely used in both 2021 Friends and Harry Potter sets. |
Be sure to take a look at the complete list to discover some relatively common parts that you might not be familiar with!
P.S. I am also using the updated list to make sure that LEGO Brick Labels continues to include labels for all of the most common current parts… The new version is coming soon!
