Mega Bloks vs Duplo Similarities & Differences – Which ONE?

The older your baby gets, the more interested they are in getting toys they can assemble (or disassemble, like my daughter). A great toy for this stage is building blocks. If you’ve got younger children, there are large-sized blocks, such as the ones in this Mega Bloks vs Duplo comparison that they cannot swallow. They’re also easy to take apart and create new structures. These have connection points that help to keep these elements together.

Why you should consider them

Children naturally like playing with toys that they can put together and take apart whenever it suits them. Playing blocks are an excellent option for playtime sessions as they’re suitable for children of any age. The only thing you would have to consider is the size of the blocks when dealing with younger toddlers. These days, you’ll even come across playing blocks with special pieces to create a variety of structures. Various sources have confirmed the numerous benefits of playing with Lego blocks or also with the Mega Bloks.

Here’s me and my daughter playing with Mega Bloks. Not for long though as she’s become very good at disassembling.

Main features – similarities and differences


With all toy options, how much you can spend will define which brand you can look at. In general, LEGO DUPLO costs more than Mega Bloks.


To enable your child to create sturdy structures, playing blocks are made of plastic. With the option you choose to buy, ensure that its plastic is safe.

Child’s age

Blocks for older toddlers wouldn’t be suitable for younger ones. That’s the case because they would have smaller, more intricately joined pieces to make sophisticated structures. Bigger pieces would work better for little ones also because they cannot be swallowed.


Block collections with special pieces such as windows, wheels, and decorated blocks allow your child to create more variety with the set.


Blocks are meant to build on each other. If the blocks don’t hold together well, that pack will fail to serve its purpose. For a child that would also be a frustrating block collection to own.


Would you like to build your child’s motor skills or creativity? Basic pieces will get them to understand how blocks work. However, to enhance creativity, sets with decorative pieces would work best.


You can easily build up your playing block set by getting compatible pieces. Therefore, choose brands that can be added on to as you will have more variety for your child.

Mega Bloks vs Duplo – Which one to choose?

Both these toy block sets come with their advantages. To help make your selection easier, consider mostly your child’s age. Mega Bloks has pieces that are large enough for smaller children. Duplo blocks are also slightly large, but some parents do not recommend them for young toddlers. This is why I chose Mega Bloks for my daughter. This option has unique shapes and the number of structures we could build are nearly endless.
