Since 1932, LEGO bricks have become a favorite in millions of homes worldwide. From curious kids to nostalgic adults, LEGO Sets has inspired fans of all ages with its endless creative options. But one question has confused LEGO lovers for years:
Why Do LEGO Sets Include Extra Pieces?
These extra pieces might seem random and often end up scattered around, collecting dust, leaving builders curious about why they’re there. The reason is actually simple and considerate. LEGO Sets add them to make up for the chance of losing small parts while building. This way, builders can finish their sets without stress, even if a tiny piece gets lost.

But what can you do with these extra pieces?
Instead of leaving them unused, there are so many fun and creative ways to use them. Whether you’re new to LEGO or an expert, these extra bricks can be turned into something special. You can use them to add your own touch to builds you’ve already made, create small new projects, or mix them with pieces from other sets to design something completely unique. If you want to keep things tidy, sorting the extra pieces by color or size can help make your next builds easier and faster.
From Leftovers to Masterpieces: How Extra LEGO Sets Spark Creativity
By using these extra pieces, LEGO builders can get even more out of their sets, turning what might look like clutter into chances to create something new. So, the next time you find extra LEGO pieces, remember—they’re not just leftovers; they’re the pieces you can use to build your next amazing creation.
In a recent article on Gizmodo, a LEGO spokesperson explained something fans have wondered about for years: why do LEGO sets come with extra pieces? The answer is simple and thoughtful. The spokesperson shared two main reasons. First, some LEGO pieces are so small that they’re too light to be weighed correctly by the machines used during packaging. Second, it’s better to add a few extra pieces than to risk builders missing any. LEGO knows which pieces are most likely to get lost or misplaced and includes extras in sets to make sure building is smooth and fun.
The Science Behind LEGO Bricks: Lightweight Design and Thoughtful Extras
Since 1952, LEGO bricks have mostly been made in a 2×1 size, with each piece weighing only 2.5 grams. This light design makes it easy for builders to use and connect the pieces, but it also means it’s hard to tell exactly how many bricks are in a set just by looking. On average, a pound of LEGO bricks has about 165 pieces. This could include 10 to 15 extra pieces, added as a helpful backup.
For LEGO fans, whether they’re building their first set or their twentieth, these extra pieces are a nice little bonus. They make sure the building process stays fun and stress-free, even if a piece gets lost. By thinking about what their customers might need, LEGO doesn’t just sell toys—they create experiences that inspire creativity and happiness. So, the next time you find extra bricks in your set, remember—they’re there to make your building experience even better.
