The major new LEGO sets of 2026 range from about 5 hours to about 30 hours of building. The Lord of the Rings: Minas Tirith (8,278 pieces) leads at an estimated 22 to 30 hours, while most of the year's headline releases land between 6 and 14 hours, which is a weekend rather than a season.
New sets are the hardest to plan for, because nobody has built them yet and there are no reviews to tell you what you are in for. Here is the full picture by size.
The biggest 2026 releases
| Set | Pieces | Estimated build time |
|---|---|---|
| Minas Tirith (11377) | 8,278 | 22 to 30 hours |
| Venusaur, Charizard and Blastoise (72153) | 6,838 | 18 to 24 hours |
| NINJAGO The Old Town 15th Anniversary (71861) | 4,852 | 13 to 17 hours |
| Koenigsegg Sadair's Spear Megacar (42232) | 4,104 | 21 to 28 hours |
| Gustav Klimt, The Kiss (31221) | 4,000 | 11 to 14 hours |
| Main Street, U.S.A. (43302) | 3,899 | 10 to 14 hours |
| Tower Bridge (21067) | 3,745 | 10 to 13 hours |
| The Ministry of Magic (76476) | 3,545 | 9.5 to 13 hours |
| Shopping Street (11371) | 3,457 | 9 to 12 hours |
| Claude Monet, Water Lilies (31220) | 3,179 | 8.5 to 11 hours |
| S.H.I.E.L.D. Helicarrier (76354) | 3,057 | 8 to 11 hours |
Look at the Koenigsegg. At 4,104 pieces it is smaller than the Klimt, and it takes twice as long. That is Technic: sub-assemblies, gearing and pin work drop the pace from about 300 pieces per hour to about 170. Piece count alone will mislead you on any Technic set.
The weekend tier
These are the 2026 sets most people can actually finish in one go, which for many builders matters more than sheer size.
| Set | Pieces | Estimated build time |
|---|---|---|
| Stranger Things: The Creel House (11370) | 2,593 | 7.5 to 10 hours |
| Arcade Pinball Machine (11374) | 2,274 | 6.5 to 9 hours |
| Hogwarts Castle: East Wing (76473) | 2,164 | 6.5 to 8.5 hours |
| Golden Retriever Puppy (11384) | 2,102 | 6 to 8 hours |
| Pikachu and Poke Ball (72152) | 2,050 | 6 to 8 hours |
| The Mandalorian's N-1 Starfighter (75442) | 1,809 | 5 to 7 hours |
| Orange Cat (21376) | 1,755 | 5 to 7 hours |
| Jaguar E-type (11381) | 1,682 | 5 to 6.5 hours |
| Sorcerer's Stone (76466) | 1,574 | 4.5 to 6 hours |
| Boba Fett (75455) | 1,544 | 4.5 to 6 hours |
What 2026 tells you about LEGO sets in general
Two patterns stand out in this year's line-up.
The middle is getting crowded. A large share of the 2026 releases sit between 1,500 and 3,500 pieces, which is the 5 to 12 hour band. That is deliberate: it is the size that fits a weekend, and a set someone finishes is a set they recommend.
Collectors' Editions are the new flagship format. The Ministry of Magic, the Sorcerer's Stone and the Hogwarts East Wing are all built to slot alongside existing models rather than replace them. For build planning this is good news, because a 2,164 piece wing is a weekend, while a 6,020 piece castle is a project.
How these estimates are made
Each figure is piece count divided by a build pace, adjusted for the type of set: about 300 pieces per hour for a standard set, about 330 for large display models over 3,000 pieces, about 250 for small detailed sets, and about 170 for Technic. A 15% band either side turns each number into a range.
The method is calibrated against documented adult build times, and it puts the Millennium Falcon at 20 to 27 hours against a widely reported 20 hours. The full explanation is in our guide to build time by piece count.
For a brand new set these are estimates, and we say so on every page. Once five or more builders have timed a set in the SetSquad app, its page shows the measured median instead. If you are one of the first to build one of these, your time is the data.
Deciding what to buy
If you want the set to be an event, go above 5,000 pieces and accept that it is a multi-week project. If you want the set to be finished, stay under 3,000. And if you want a genuine challenge rather than a long one, take the Technic option at half the piece count.
