Age Guide: How to Choose the Right Building Toys for your Child

The type of building toy you should choose for your child will largely depend on their age and skills. Here, we have outlined what you should be looking for in a building toy, depending on the age of your child.


Younger children will benefit from a toy with chunkier pieces. Ensure there are no small parts which could pose a choking hazard. Toddlers love bright, bold colors and interesting shapes.

Instead, go for something which they will be able to build anything they choose rather than having to follow complex instructions.

Children aged 5 years old can follow simple instructions, with help from parents. You can choose something with more parts now your child is older too. Kids this age will probably enjoy building games, too.

7 to 9 Year Old Kids
