Best Building Toys for Kids & Toddlers of 2020

Help your child discover and develop new skills with building toys they love and enjoy.

Are you looking for more than just a toy? Do you want something that helps establish early learning, engineering, logic, and spatial skills? If so, you may want to check out this list of the best building toys for kids.

Open-ended toys, like building blocks, help encourage your child to develop problem-solving skills as well as motor skills (1). If you’re looking for more than just another toy to add to the shelf, building blocks can be a great choice.

Let’s explore what you should look for in building toys — then I’ll let you in on some of my favorites on the market.

Why Choose Building Toys?

There are a lot of toys out there, and that makes your choice as a consumer harder than ever. Before you start shopping for building toys, take a look at this buyer’s guide for the features you’ll want to keep in mind.

Great building toys should encourage development. Here are some reasons to pick building blocks and building toys over other kinds of toys out there.

Motor skills

Picking blocks up, taking blocks apart, and putting them back together all build finger dexterity. These actions help your child finesse both fine and gross motor skills.


Building with blocks can be frustrating — in a good way. Your child will quickly learn their structures will tip over if they aren’t balanced. They’ll learn what fits where, and then experiment with how to correct those problems.

Social and language skills

Building toys usually inspire collaborative play, which encourages communication skills and the need for language (2).

Many other skills can also be strengthened through the use of building toys and blocks. Children can have fun while also learning — using building toys is a great way to make it happen (3).

What to Look For

When you’re shopping for this type of toy, here are some things you’ll want to check out before you buy.


It’s likely your building blocks will be dumped out of boxes, thrown, and stepped on — usually by mom or dad in bare feet. Make sure you choose a building toy that won’t break easily. Frequently inspect your building toys to make sure none are damaged or have sharp edges.


There are great options made out of plastic or wood. Check the product information and make sure the paint and materials are safe for children to touch or even chew on (4).


Look for pediatrician-approved, Organization-recognized, and award-given products. This can help point you in the right direction for high-quality toys that deliver.
