The Definitive List of the Longest LEGO Sets Ever Made

Last updated 2nd January 2024

Longest LEGO Sets

LEGO seems to be reaching new heights each year, continuously producing bigger, better, and more impressive sets. These present a challenge to build, but a bigger challenge to display.

In this article, we run through the longest LEGO sets ever made.

LEGO Daigon Alley

9. 75978 Diagon Alley

Length: 102 cm

The Diagon Alley set from 2020 gave us four buildings from the famous wizarding shopping street. Inside can be found Ollivanders Wand Shop, Scribbulus Writing Implements, Quality Quidditch Supplies, Florean Fortescue's Ice Cream Parlor, Flourish & Blotts bookseller, Weasleys' Wizard Wheezes, as well as the entrance to the Daily Prophet. The four modular builds combine to form a set that stretches to over a metre long.

LEGO Concorde

8. 10318 Concorde

Length: 105 cm

Being designed for long-haul flights, the real-life Concorde was significantly longer than the common Boeing 737 and Airbus A320 models that most of us will have flown on for short hops. The LEGO version measures in at 105 cm long and features a tiltable nose, which used to be dropped when Concorde was landing, taking off, or being taxied, because it's unusual long length prevented pilots seeing the runway when the nose was in its lifted position.

LEGO Venator-Class Republic Attack Cruiser

6=. 75367 Venator-Class Republic Attack Cruiser

Length: 109 cm

The UCS Venator is identical in length to the UCS Imperial Star Destroyer (75252) and shares sixth place on the list of longest LEGO sets. The Venator was released to commemorate the 20th anniversary of the Clone Wars, where it was a key part of the Galactic Republic's fleet. The actual ship is said to be around 1.1 km long.

LEGO Imperial Star Destroyer

6=. 75252 Imperial Star Destroyer

Length: 109 cm

This updated 2019 version of the Imperial Star Destroyer was 1,688 pieces larger and 15 cm longer than the original UCS Imperial Star Destroyer (10030) from 2002. With a whooping 4,784 pieces, it's a colossal build and one of the largest LEGO Star Wars sets ever produced.

LEGO Liebherr Crawler Crane  LR 13000

5. 42146 Liebherr Crawler Crane LR 13000

Length: 111 cm

The Liebherr Crawler Crane LR 13000 depicts one of the world's most powerful conventional crawler cranes and is one of the largest LEGO Technic sets ever released. In addition to being one of the longest sets LEGO have produced, it's also one of the tallest.

LEGO Orient Express

4. 21344 Orient Express

Length: 116 cm

This set is the most recent on the list, and was adapted from a fan-based submission as part of LEGO Ideas. The set includes the train's engine, tender, the dining-car, and the sleeping-car. At 116 cm long, it's the second longest train LEGO have made.

LEGO Hogwarts Express - Collectors' Edition

3. 76405 Hogwarts Express - Collectors' Edition

Length: 118 cm

The Hogwarts Express - Collectors' Edition is a 1:32 scale replica of the world's most famous locomotive. The set includes the engine, coal tender, and one of the train's passenger carriages. At 118 cm long and 5,129 pieces, it's the longest and largest LEGO train, just edging out the Orient Express.

LEGO Super Star Destroyer

2. 10221 Super Star Destroyer

Length: 124.5 cm

The longest Star Wars UCS set so far is the Super Star Destroyer, which was released in 2011. The term Super Star Destroyer is used to refer to ships larger than Imperial Star Destroyers, with the largest of this class being the Executor Star Destroyer, which was 19 km (12 miles) long. With a subject that big, we're glad LEGO chose to draw the line at 124.5 cm for the set's length!

LEGO Titanic

1. 10294 Titanic

Length: 135 cm

The 10294 Titanic was titanic in both name and nature. At 135cm, it's over 10 cm longer than the next longest set, and with 9,090 pieces, it's one of the biggest LEGO sets ever made.

The set is also one of the most faithful LEGO replicas of a real-world vehicle. It's a perfect 1:200 scale model of the actual ship in both length and width, with the real vessel being 269m long and 28m wide. Because the set is under 50 cm tall and only 14 cm wide, it's not as difficult to display as some of the towering sets LEGO have produced.

It's hard to think of a set that could potentially take the "Longest LEGO set" title off the Titanic. Perhaps if LEGO decided to make a new Great Wall of China set or a large-scale model of a Boeing or Airbus passenger jet…

The table below lists the top 15 longest LEGO sets.
