Where are LEGO sets made?

In a 2022 news release, the LEGO Group said it had five manufacturing sites on three continents: Billund in Denmark, Kladno in the Czech Republic, Nyíregyháza in Hungary, Monterrey in Mexico and Jiaxing in China. The same release said it planned to add sites in Vietnam and Virginia, USA.

Are LEGO sets a good investment?

We don't make value or resale claims about any set. A LEGO set on this page is listed for building, and that's how we describe it: by line, stated age and what the listing says is in the box. If you're buying, buy the set someone wants to build.

That depends on the builder, not the brand. What our data shows is range: LEGO sets in our tables run from DUPLO boxes listed for 1.5+ to Botanicals and Star Wars display sets listed for 16+ and 18+, with Classic brick boxes in between. A set that fits the builder's stated age and interest is the one worth buying.

Where can I buy LEGO sets?

We track LEGO sets on Amazon US, and the table on this page links to each listing with a Check price button. The maker also runs its own site at lego.com. Check the set number on the box, like 10698 or 75192, to be sure two listings are the same set.

What's the difference between LEGO and LEGO DUPLO?

DUPLO is LEGO's line of larger bricks for small hands. In our data, DUPLO sets state ages from 1.5+ and 2+, while standard LEGO brick sets start at 4+. One DUPLO listing says it combines with other LEGO DUPLO sets. We don't claim more fit than the listings state.

LEGO Sets: DUPLO to Icons, Lines and Stated Ages

Q: Who makes LEGO?

The LEGO Group. Its history page says the company was founded in 1932 by Ole Kirk Kristiansen and is still owned by the Kirk Kristiansen family. The site's footer gives LEGO System A/S in Billund, Denmark, as the registered address.

What LEGO makes

LEGO makes brick building sets: plastic bricks with studs on top that press together and hold. That's been the idea for a long time. The LEGO Group's own history page says the company was founded in 1932 by Ole Kirk Kristiansen and is still owned by the Kirk Kristiansen family.

We track 329 LEGO sets on Amazon US as of 2026-10-23, the biggest single-brand table on this site. In our data they fall into several types: brick sets, licensed sets, toddler blocks, STEM kits and a few others. The table above has all of them. This page walks through the lines with examples, so you can tell which part of the table to read.

Here's the short map:

Line	Who it's for, by stated age in our data
DUPLO	Toddlers, from 1.5+
Classic	Open building, from 4+
City, Friends, Ninjago	Play sets, around 5+ to 7+
Star Wars and other licensed lines	From kids' sets to 16+ display builds
Technic, Boost	Mechanisms and motors, from 7+
Architecture, Botanicals, Icons	Display builds, 12+ to 18+

LEGO DUPLO: the toddler line

DUPLO is LEGO's line of bigger bricks. Eight DUPLO sets in our data sit in the toddler-blocks type:

10913 Brick Box, 65 pieces, 1.5+, storage included
10914 Deluxe Brick Box, 85 pieces, 1.5+, storage included
10954 Number Train, 23 pieces, 1.5+
10941 Mickey & Minnie Birthday Train, 22 pieces, 2+
10931 Truck & Tracked Excavator, 2 to 4
10882 Train Tracks, 2 to 5
10825 Miles Exo-Flex Suit, 37 pieces
10543 Superman Rescue

The brick boxes are the plain start. The trains and vehicles add a toy to roll around. The 10882 Train Tracks listing is specific about fit: it says it works with existing LEGO DUPLO train sets, and that its action bricks don't work with older DUPLO trains. That's the kind of line worth reading before you buy track for a train you already own.

The 10914 listing says it combines with other LEGO DUPLO sets. We repeat that and add nothing more.

LEGO Classic: open building

Classic is LEGO's line for building whatever you like. Eight Classic sets in our data:

11008 Bricks and Houses, 270 pieces, 4+
10696 Medium Creative Brick Box, 484 pieces, 4+
10698 Large Creative Brick Box, 790 pieces, 4+
11011 Bricks and Animals, 1,500 pieces
11717 Bricks Bricks Plates, 1,504 pieces, 4+
11036 Creative Vehicles, 5+
10713 Creative Suitcase, 4+
A Classic Set of 2 with 10696 and 10700 Building Blocks Box plus a green base plate

Classic boxes are what most families mean when they say "a box of LEGO". They come with ideas but no single target model. For a 4-year-old's first standard-brick set, a Classic box is the plain choice.

The range inside Classic is big. Bricks and Houses has 270 pieces. Bricks Bricks Plates has 1,504, and both list 4+. A bigger box isn't a harder box here. It's more of the same bricks.

City, Friends and Ninjago: play sets

These lines build a scene to play in, with figures.

City. 60045 Police Patrol, with 3 minifigures. City Space Mars Research Shuttle 60226, 5+. 60304 Road Plates, 5+, which lays out streets for other City builds.

Friends. 41323 Snow Resort Chalet, 402 pieces. 41422 Panda Jungle Tree House, 265 pieces, 7+.

Ninjago. Titanium Dragon and ElectroMech. Neither listing in our data states an age.

Play sets suit a kid who builds in order to play: the build is the first half of the afternoon, the story is the second half. The 60304 Road Plates set is the giveaway for this kind of builder. Nobody buys streets unless they plan to drive somewhere.

Star Wars and other licensed lines

LEGO makes sets for many licensed lines. We name them only as the listings do.

Star Wars. Seven sets in our data:

75192 Millennium Falcon, 7,541 pieces, 16+
Star Wars: A New Hope Imperial Star Destroyer 75252, 16+
Star Wars TIE Fighter 75095, 14+
Sandcrawler, 1,669 pieces, 11 minifigures
Slave I
Star Wars Snow Speeder 75144
Star Wars Y-Wing Starfighter 75181

The 75192 Millennium Falcon has the largest piece count of any LEGO set in this page's examples. For a fuller list sorted by stated age, see the best LEGO Star Wars sets.

Other licenses in our data. Indiana Jones Motorcycle Chase (79 pieces), 10594 Sofia the First Royal Stable and Harry Potter Hogwarts Castle 71043.

Technic and Boost: mechanisms

Technic. Technic Heavy-Duty Tow Truck 42128, 11+. LEGO's own Technic page describes the line as sets with functioning gearboxes, wheels and axles that kids put together themselves.

Boost. 17101 Boost Creative Toolbox, listed 7 to 12. It's in the STEM kits type in our data. Read the listing for what it needs to run.

Lucho saw the tow truck in the table and stopped scrolling. "That's the vehicle I respect most at work," he said. "It shows up on everybody's worst day and fixes it." Then he asked if it tows. I said read the listing. He did.

Architecture, Botanicals and Icons: display builds

These are sets built to sit on a shelf.

21034 London, 468 pieces, 12+ (Architecture)
21042 Statue of Liberty (Architecture)
Botanicals Bonsai Tree 10281, 18+
Botanicals Flower Bouquet 10280
Icons Porsche 911 10295

The Bonsai Tree is listed 18+. That label isn't a warning about difficulty alone. It's the maker saying who the set is for. A bouquet that never needs water is the only flower arrangement a math teacher can be trusted with.

LEGO vs K'NEX

Both are building systems, and they build in different ways. LEGO bricks press together on studs and make solid shapes. K'NEX rods click into connectors and make open frames. In our data, LEGO's stated ages run from 1.5+ (DUPLO) to 18+ (Botanicals). K'NEX runs from 3+ (Kid K'NEX) to 16+ (the 6-foot Ferris wheel), with most sets at 7+ to 9+. Both have motorized and STEM options: LEGO Boost at 7 to 12, and K'NEX motorized sets at 7+ and 8+. Pick LEGO for a model that looks like the thing. Pick K'NEX for a model that shows how the thing is put together, like a roller coaster's track and supports.

LEGO vs nanoblock

nanoblock makes micro bricks. Our data records its brick size as micro, 4 to 8 mm, much smaller than standard LEGO bricks. The nanoblock listings we track mostly state 8+, and several state 15+, with piece counts from 110 to 1,530 where stated. LEGO's range starts far younger, with DUPLO at 1.5+ and Classic at 4+. A nanoblock model is small and detailed, made for a desk. A LEGO set ranges from a toddler's brick box to a 7,541-piece display ship. We don't claim the two systems fit together, and no listing in our data says they do.

LEGO vs Mould King

Mould King listings in our data are mostly big vehicle and machine kits: trucks, cranes, excavators, engines and a roller coaster. Piece counts run from 1,015 to 8,506 where stated, and every listing that states an age says 14+. LEGO covers that end of the hobby too, with Technic and the 16+ display sets, but its range runs all the way down to toddlers. If you want a big mechanical build, compare piece count, stated age and what each listing says about motors and controls. We don't claim parts fit between the two brands. No listing in our data says so.

Set numbers, booklets and lost instructions

Every LEGO set in our data that lists one has a set number: 10698, 60045, 75192, 42128. That number is the most useful thing on the box. It tells two listings apart when the names are close, and it's what you search for when a booklet goes missing.

Keep the booklets, flat, near the finished builds. If one goes missing, start with the maker's site and the set number. We haven't checked the maker's instruction pages for every set, so we don't link them here.

A booklet is the one part of a set that can't be replaced by a spare brick. Treat it that way.

How to pick a LEGO set

Find the line for the age. DUPLO for toddlers, Classic from 4+, play lines around 5+ to 7+, display lines for teens and adults.
Check the listing's own age. Lines are a guide. The box is the rule.
Open building or a target model? Classic for open building. Everything else has a picture to match.
Space. A 7,541-piece set needs a table for weeks. A 270-piece Classic box needs a lap.
Set number. Write it down before you shop. It's the surest way to compare listings.

Build-tray advice for big sets

A 7,541-piece set has 7,541 chances to roll off a table. A tray with a raised lip catches most of them. Build the current step on the tray, keep the next bag closed, and the floor stays a floor.

The tray also solves the younger-sibling problem. A tray can be lifted onto a high shelf between sessions with the half-built model still on it. A pile of loose bricks on a carpet can't.

One more trick for big builds: sort the bag for the current step by color into small bowls before you start the step. It takes a minute and saves ten.

Small-parts safety

Check the age label on the listing. Toys with small parts are a choking hazard for children under 3.

Standard LEGO bricks are small parts. If a house has DUPLO for a toddler and standard bricks for an older child, keep them in separate bins, and keep the older child's bin closed and up high.

Who should skip a LEGO set

Skip any set whose stated starting age your child hasn't reached. In our data that ranges from 1.5+ for DUPLO to 18+ for the Bonsai Tree.

Skip a 16+ display set for a kid who wants to play with the finished model. Those are built to sit still. A City or Friends play set fits that kid better.

And skip a big licensed set for someone who doesn't care about the license. A Classic box gives more building per piece of interest.

For more brick sets by age from many makers, see building blocks.

Find the line, check the number on the box, and get a tray.
