Top 15 Biggest LEGO Sets With the Largest Number of Pieces, Ranked in 2025
- Lego was once a building toy for children has expanded its audience to include teens and adults. And the sets themselves have expanded in detail, utility, and variance. However,when it comes to big LEGO sets we tend to think of sets like the Ultimate Collectors Series Millennium Falcon, or the original Lion Knights Castle, but are they the biggest? What is the largest LEGO set by number of pieces? What is the tallest LEGO set? Or when do LEGO sets go on sale? Read on and this up-to-date guide tracks the biggest Legos of them all – namely the Lego sets with the most pieces. We'll be looking at the sets with the highest brick count; but expect to also find out about the tallest commercially released LEGO set and the longest LEGO set. If you like brick related facts, you are in for a treat!
What Is Lego Set?
LEGO Group, a Danish company, was founded in 1932. Headquartered in Billund, Denmark, the company is one of the world’s largest toy manufacturers, renowned for its iconic plastic building blocks. The LEGO Group began manufacturing the interlocking toy bricks in 1949. Over the decades, LEGO added mini-figures, Technic sets, a variety of hinges, arches, windows, and more to their products.As of 2025, LEGO was the largest toy company in the world. The company's flagship product, LEGO, consists of variously colored interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts.
LEGO pieces can be assembled and connected in many ways to construct objects, including vehicles, buildings, and working robots. Anything constructed can be taken apart again, and the pieces reused to make new things.
LEGO maintains a very positive, family-friendly atmosphere, conveying the message of “providing healthy, educational, fun, and quiet play for children.”
Where to Buy LEGO Sets Online?
If you’re after a hard-to-find set, the first place to look should be the world's biggest LEGO Shop at LEGO.com (up to 3% super cash back). You'll find the very latest models, exclusive sets, accessories and more. During some parts of the year, you'll even find seasonal holiday sets.
You can buy sets before they launch to the general public. You can receive free sets as incentives for spending money. And there are several sets that are exclusive to the LEGO Store, which cannot be bought from a third-party retailer.
If the LEGO shops don’t have the set you’re looking for, there are still plenty of other places to buy LEGO products! You may want to try searching toy stores, supermarkets, specialty gift shops, department stores, or the Internet,such as:
Best Buy (up to 0.5% super cash back)
Walmart (up to 1% super cash back)
Kohl's (up to 3% super cash back)
StockX (up to 2% super cash back)
While these online storefronts do not have the point system or the exclusivity of the official store, they offer modest discounts for most of their sets. The LEGO Store, meanwhile, typically charges full retail price except on select occasions, like when it's trying to get rid of inventory near the end of a set's run.
Where to Buy Retired Sets Online?
Lastly, there are the unofficial online marketplaces on Craigslist, EBay, Facebook, and more. If you're looking for a retired set, this is your only option, and be warned: your acquisition will come at a steep price. Definitely get in touch with the seller directly, definitely haggle, and definitely shop around to get the best possible deal.
Where to Buy LEGO Sets in Stores?
Brick-and-mortar stores are your other option. It is unlikely you'll find a wider diversity of sets in person than you would online, but many people prefer personalized attention and want to physically handle a set before purchasing it.
The LEGO Insiders program and its point system carry over to either option.
Find one Lego store near you using the store finder.

11.LEGO Creator Taj Mahal - 10256

When Is the Best Time to Buy LEGO Sets?
Aside from regular discounts at the box-stores (which are the baseline default, rather than the exception), LEGO sets rarely receive discounts. The demand is high, and LEGO would rather retire a set than discount it. But there are specific times of the year when LEGO sets go on sale to watch out for.
LEGO typically celebrates May 4 (Star Wars Day) by offering double the Insider points for purchasing Star Wars sets. LEGO also celebrates March 10 (Mario Day) by partnering with Nintendo and offering similar deals. So watch out for notable anniversaries, particularly as they relate to 3rd party franchises.
Always look for clearance deals at the box-stores, which are more common at the beginning of the year. That's when LEGO retires scores of old sets and launches scores of new sets. This requires the 3rd party retailers to refresh their inventory.
Lastly, the holiday season is ideal for deep discounts, particularly on Black Friday and Cyber Monday. Amazon Prime Days, which run in July and October, are also solid opportunities. Keep an eye out for any upcoming sales events for potential LEGO deals.
