1. Botanicals
These decorative flower sets easily topped the charts of retailers' bestsellers and Lego's own internal data.
They look great on shelves and require much less maintenance than their real-life counterparts; plus, building these models is an exercise in mindfulness.
Popular choices include orchids, succulents and bonsai trees.

2. Icons
Icons are aimed at adult fans and collectors. Many of the models feature advanced building techniques and hundreds of tiny pieces to create detailed miniatures for display rather than play.
You'll find popular 'icons' of all shapes and sizes, from the Game Boy and Simpsons' Krusty Burger, to massive sets such as Lego's nearly 1.5-metre-tall recreation of the Eiffel Tower.

3. Technic
These sets focus on larger moving parts, including working engines, gearboxes, axles, and wheels. The models are meant to move – and some even have a motor for remote-controlled operation.
Forget 'typical' square Lego bricks. Rounded bars and axles fill packs to recreate hypercars like the McLaren P1, moving models of Planet Earth and the Moon in orbit, F1 cars, motorbikes, SUVs, planes and more.

4. Star Wars
From a galaxy far, far away to your living rooms, Lego's first-ever licensed theme remains a popular choice with adult fans and kids alike. Many of them top retailers' bestselling lists.
Whether you're battling Darth Vader and Luke Skywalker or building a Yoda bust, the Star Wars range features the most-loved characters. You can also find some of the largest-ever Lego models, such as the Ultimate Collector Series (UCS) Millennium Falcon or the UCS Razor Crest.

5. City
Remember the adverts: 'There's a fire in Lego City'? The interest in these sets shows no signs of cooling down.
Created in 1978 (and known as Lego Town until it was rebranded in 1999), Lego City is aimed at children over 4 and designed as the next step from Duplo.
Future town planners can create whole neighbourhoods, packed with fire engines, cars, train stations, food trucks and aeroplanes.

6. Speed Champions
Lego cars are nothing new. However, unlike Technic, Speed Champions tend to be significantly cheaper and much simpler to build.
You'll get recreations of iconic cars from film, TV and F1 models or scaled-down versions of hyper- or supercars. Just know that these are minifigure-scale and much smaller than their Technics counterparts.

7. Creator 3in1
The sets in this theme showcase the full potential of a Lego brick; you can build three different models from the same pack.
They usually range from houses and castles to animals and vehicles, and include instructions to build each of the three sets so you won't be left in the dark.
It's an extremely popular line that frequently tops retailers' bestselling lists, including Amazon's.

Lego sets to look out for in 2026
While we expect the above to remain popular throughout 2026, these are the themes, trends, and features to look out for from Lego this year.
Lego Pokémon
With 90s Pokémania seemingly gripping the world again in the 2020s, it was only a matter of time before these pocket monsters were turned into Lego.
Popular sets include an Eevee, Pikachu and a display of Charizard, Blastoise and Venusaur in action.

Lego Stranger Things
While Lego has been no stranger to releasing sets based on the popular Netflix show, there have only been a handful from 2019 to 2022.
Awful puns aside, we've seen new models in the theme released following the show's conclusion. These include new BrickHeadz and a set based on the Creel House that was featured in the show's fourth series.
Pick up these new sets below:
Lego FIFA
Ahead of this year's World Cup, Lego has released a few football-inspired sets under the Editions theme.
There aren't many but they're certainly popular. Right now, you can choose between a World Cup trophy or a FIFA football.
Pick them up below:
Lego Smart Play blocks
Lego's newest innovation rebuilds playtime with 'smart bricks' that add flashing lights and sounds to sets. These new parts are smart tags or minifigures, and a 2x4 smart brick that reacts to movement.
While you won't need any additional devices to use these features, you will need to charge the smart bricks with an included charger.
So far, only a few Star Wars playsets feature this new system, but expect to see more released throughout 2026.
