Selection Criteria

Shortlisting a handful of the best LEGO sets that cost less than $20 is by no means an easy task, as there are hundreds of models to choose from. Choosing the best LEGO set under $20 is further complicated by the fact that each of LEGO’s themes features at least one set that costs less than $20.

That’s why I used a broad spectrum of parameters during the selection process that assisted me in choosing the sets you’ll find in this article. Here are some of the most important criteria I utilized to pick the best LEGO sets under $20.

  • Set theme – I identified the most popular LEGO themes and then selected a set from each theme that is priced below $20 so that you can choose a classic LEGO set or opt for one of the sets inspired by superhero movies.
  • Set size – Each set in this article is aimed at users with different set building skills. A model with fewer than 50 pieces is best suited for a novice builder, while sets with more than 200 pieces are an excellent choice for an experienced LEGO builder.

Our guide to the best LEGO sets can help you identify some of the best LEGO sets ever created.

A Brief Guide to the LEGO Themes

All LEGO sets are released within a specific theme, and currently, LEGO publishes sets within forty themes. Some of these categories, like LEGO City or LEGO Technic, are decades old. On the other hand, themes such as LEGO Art or LEGO Super Mario were only recently added to the brand’s product lineup.

You’ll find inexpensive sets that cost $20 or less within each theme, so let’s take a closer look at some of the brand’s most popular themes.

LEGO Classic

This theme was reintroduced in 2014 after being discontinued for more than a decade. Initially, LEGO published sets within the Classic theme from 1966 until 1999. All sets within this theme allow you to build a variety of models. The most affordable sets from this theme are:

LEGO Classic Bricks and Houses

LEGO Star Wars

As one of LEGO’s longest-running themes, the Star Wars theme contains hundreds of sets inspired by the Star Wars universe. Currently, this theme features more than sixty sets, including 11 sets that cost less than $20. The least expensive LEGO Star Wars sets are:

LEGO Star Wars Mandalorian Battle Pack

LEGO Creator 3-in-1

The first Creator 3-in-1 theme set was released in 2003. Sets from this theme are equipped with specialized bricks to build unique models. Here are a few sets from this theme you can get for less than $20.

Set’s Versatility

Getting a set that allows you to build just one model can be limiting. Moreover, children get tired of toys quickly, which is why parents often choose LEGO sets that have more than a thousand pieces.

However, large sets usually cost much more than $20, which can be challenging to assemble. Opting for a set from the LEGO Classic or LEGO 3-in-1 Creator themes will enable your child to combine elements freely.

This, in turn, will make a set more interesting because it will provide a child with a wide range of play scenarios. You should also consider sets that include a combination of buildable models and mini-figures since they’re fun to play with and inspire a child’s creativity.

LEGO Sets Under $20 for Children Below the Age of 4

Standard LEGO sets contain pieces a child can swallow, making these sets unsuitable for toddlers and preschoolers. You should opt for one of the LEGO Duplo sets that cost less than $20 in case you’re looking for a set that is safe for children under the age of 4.

Luckily, you’ll have a variety of options at your disposal because most LEGO Duplo sets are inexpensive. This product line currently features a dozen sets priced under $20. Here are some of the least expensive LEGO Duplo sets you should consider:

LEGO DUPLO Classic Heart Box

Besides being fun to play with, these sets can also help a child learn new things and improve creative thinking skills. Go through our guide to the best LEGO Star Wars lightsaber sets to find out if any available models are suitable for preschoolers.

Navigating through Retired LEGO Sets Under $20

LEGO Friends Heartlake City Play Hair Salon

Discontinued sets like the Heartlake City Hair Salon 41391 or Thanos Mech 76141 cost less than $20, and they’re still relatively easy to find. Retired sets remain available on the market for as long as stores have them in stock, but their price is usually higher than the sets that are still in production.

Finding a discontinued set that costs less than $20 shouldn’t be too tricky, but you should only buy these sets from reliable sources to avoid getting a set that’s missing crucial pieces. Arguably, one of the most significant downsides of retired LEGO sets is that replacement parts can be hard to find.

The easiest way to find out if a set was discontinued is to check if it is still listed on LEGO’s website.

The Most Important Factors to Consider while Choosing a LEGO Set Under $20

LEGO offers a broad spectrum of sets from forty different themes that cost $20 or less. Such an abundance of available options makes finding a set that meets all your criteria challenging.

That’s why you’ll need to utilize several other search parameters besides your budget to shortlist the best sets within this price range. However, I’ve selected some of the most critical factors that can make your search for the best LEGO set under $20 easier, so let’s take a quick look at them.

Child’s age and gender

Although LEGO sets are made for all children, some topics might be more suitable for boys or girls. For example, taking the child’s gender into account can help you decide if a set that contains a buildable model of a superbike or cat-grooming car is a gift your child will like.

LEGO Creator 3in1 Superbike

LEGO sets are designed for specific age groups, and you should avoid getting a set that is made for kids older than your child.

Set’s skill development potential

Playing with LEGOs can help a child develop various skills that range from creative thinking to planning and organization. So, for instance, a set from the LEGO Classic theme can inspire a child to seek creative ways of building different models.

Getting a set that requires a child to follow instructions during the assembly process might improve literacy and problem-solving skills. In addition, all LEGO sets enable kids to better understand spatial relations between objects and encourage three-dimensional thinking.

Set’s size and complexity

The number of pieces in a LEGO set often affects its price, which is why sets that cost less than $20 don’t have more than 300 pieces. Nonetheless, a set with over 200 pieces can still be challenging to assemble, especially if a child doesn’t have advanced set building skills.

It is better to opt for a set with less than 100 pieces if you’re searching for your child’s first LEGO set, while more complex sets are better suited for kids who already have some experience with building sets.

The topic the set is based on

Each LEGO theme includes sets that cover a variety of topics. For example, sets from the City theme can be inspired by firefighters, police officers, or camper vans, and which one you should choose depends on your child’s preferences.

Knowing which Star Wars or Marvel movie your child likes the best can make choosing a set from either of these LEGO themes much easier. Sets from the LEGO Classic theme don’t have a specific topic, and they can be useful if you want to encourage your child to explore its interests.

Availability of spare parts

LEGO bricks and plates have a reputation for being indestructible, but the same cannot be said for all the parts you’ll find in LEGO sets that cost under $20. LEGO produces replacement parts for all of its sets, including the retired models.

However, replacement parts aren’t available for all old LEGO sets, and you need to check if the part you’re looking for is listed on the Pick a Brick section of LEGO’s website.

The Advantages of LEGO Sets Under $20

A great introduction to the world of LEGO sets

It isn’t easy to know if your child will enjoy playing with LEGOs if they never owned a LEGO set. Getting a set that costs less than $20 can be a great way to introduce a child to the LEGO world and determine if they would appreciate owning a larger and more expensive set.

A wide variety of options

Each of LEGO’s forty themes contains at least one and often many more sets that cost less than $20. This enables you to get a set that matches your child’s interests and age.

Skill development

Learning how to read, excellent problem solving, collaboration, and creative thinking skills are some of the benefits of playing with LEGOs from an early age.

The Disadvantages of LEGO sets under $20

LEGO sets under $20 contain a limited number of pieces

Building a set that has fewer than 300 pieces doesn’t take more than a few hours, so your children might get bored quickly with a set that is too easy to assemble.

Even though assembling the elements from this set is easy, the manufacturer included the building instructions that guide a child through the assembly process.

This set contains bricks in 29 different colors and special pieces that enable kids to design cars, houses, or boats. In addition, building instructions and ideas are included in the set so that children can use them whenever they lack inspiration for their next project.
