When it comes to larger building blocks for younger children there are two big names that seem to dominate the scene. These being Mega Bloks and Lego. The Lego Group makes blocks specifically for younger children known as Duplos, and many parents wonder what the difference between Mega Bloks and Duplos is.

In short, both Mega Bloks and Duplos share similar features such as locking mechanics and assembly. The main difference between the two different brands is the quality. Duplos are much easier to put together and take apart and are also made of much more sturdy materials. 

Of course each has their own unique aspects which make them special and different in their own right but for many people the reason to choose Duplos boils down to the quality issue. 

If you are interested in learning more about these two signature building blocks and what their other differences are, you will want to keep reading the rest of this article.

The Differences Between Duplos and Mega Bloks

The biggest difference between these two options is the quality (as mentioned above) and the price. Mega Bloks are considerably cheaper than buying the same amount of Duplos so you will certainly get more for your money by purchasing Mega Bloks. 

However, the initial purchase price is only one of the things that you should consider. 

Why choose Duplos? 

Duplo is a product that the Lego Group came up with way back in 1969, when they released the first bricks. These bricks were meant to be a special product that was made specifically for younger children.

These younger children, those under the age of five, were to benefit from these Duplo pieces due to them being double the size of a standard LEGO brick. That made for easier handling and safer playability, while also serving as a creative tool for toddlers. 

The way that Duplo works is essentially the same as standard Lego bricks. They snap together via studs and hollow bits, and stay locked into place tightly due to their high quality construction.

Studs on top of each brick are used to lock into spaces beneath another brick, locking them both into place and forming a tight yet easily breakable bond. These Duplo  blocks are a fine toy for many kids as they are sturdy enough to be made into structures and vehicles, yet easy to break down into parts again and be used in another creation.

Duplo  blocks come in a variety of different shapes and sizes, some even have print on them or be used for special purposes as some pieces may be ladder pieces, tubes, or even doorways.

What Do Duplos Offer that Mega Bloks do Not?

For starters, the plastic that the Lego Group uses in all of their products is renowned for how sturdy, tough, and thick it is. Duplo bricks, just like their standard sized counterparts, are made with high end plastic that is very hard to break, and is designed not to wear down, or even crack.

Mega Bloks, on the other hand, features pieces that are made out of much flimsier and cheaper plastic. While this does make them considerably cheaper, it also means that they are more prone to breakage and wear than Duplo  blocks are.

Another thing that sets Duplos apart from Mega Bloks is the fact that Duplo blocks are much better at sticking together consistently.  This means that if your child is aiming to build elaborate structures and does not plan on breaking them apart any time soon, then Duplo is much better.

Mega Bloks often have many inconsistencies in sizing so some blocks will fight together so tightly that it is virtually impossible for a child to take them back apart while other blocks will be so loose that it is difficult to build anything with them at all. 

These type of inconsistencies are virtually never found in Duplos which is why many people prefer them. 

The size and feel of Duplo blocks are also much better than the competitors. They fit in little children’s hands well and are perfect for building and making great creations.

A big draw of Duplos is that by the time children get around the age of four or five they start to crave blocks that stick together better. That means that the tightly fit Duplo  blocks will serve them better than the looser fitting Mega Bloks that they will most likely outgrow.

Another thing to keep in mind is the fact that Duplo  blocks can be used in conjunction with standard Lego pieces. This means that even when your child grows up they can use their Duplos  in their Lego creations which allows Duplos to be used for much longer than any of the cheaper blocks. 

Why choose Mega Bloks? 

At first glance, you may think that Mega Bloks and Duplos are the same thing, but there are some key differences that set them apart. For starters, Mega Bloks tend to have very thick and bulky studs atop them, while their bottom halves are quite a bit thinner than DUPLO blocks.

There are, however, Mega Bloks that look nearly identical to Duplos. They share a chunky, blocky design and small, hollow studs atop them. 

Because of this thinner construction, Mega Bloks are considerably cheaper for comparable sets which is why so many people want them instead of the much more expensive Duplos. 

For example, a starter set from Mega Bloks (found here) is almost half the price of a starter set of Duplos (found here) and the Duplo starter set only has 85 pieces to the 150 pieces that the Mega Bloks set has. 

As you can see you get much more quantity with Mega Bloks than you do with Duplos. 

What Does Mega Bloks Offer That Duplo Does Not?

While it is true that Duplo is much better in terms of quality and durability, Mega Bloks is no slouch in that department. Although their blocks are generally not made to the same standards as the Lego Group holds for their Duplo blocks, they are still fine toys for young children.

One of the biggest draws of Mega Bloks is the fact that they do not stick together as strongly as Duplos do. This may seem like a bad thing, but when taking into account the age group that these toys are made for, it can actually be quite a big plus. 

In fact, Mega Bloks pieces do not really “stick” to one another the same way that Duplo and Lego blocks do. Rather, they seem to float atop each other, simply using gravity to keep themselves in place.

Because the blocks are not so tightly stuck together once assembled (they can come apart just by lifting them up), Mega Bloks are a wonderful choice for children that are very small and those that do not possess much strength.

However, as mentioned earlier, the Mega Bloks are much more inconsistent which means while most will be looser some of them will be so tight that children won’t be able to separate them at all. These inconsistencies can be extremely frustrating to children so that is something to keep in mind. 

Of course, one of the biggest reasons that people choose Mega Bloks is the fact that they cost quite a bit less than Duplos do. This will save parents money when trying to purchase their kids toys that will fuel their creativity.

While Duplo may have more longevity due to them being compatible with Lego bricks, Mega Bloks being more cost-effective is still a giant plus for many parents, especially  since once your child outgrows these blocks they might not ever want to use them again! 


Overall, Duplos and Mega Bloks each have their own strengths and weaknesses. Duplo  products tend to be sturdier, tougher, and stick together better. They can also be used in conjunction with regular Lego bricks as your children get older, making them a useful toy far past their intended age group.

Mega Bloks, on the other hand, are cheaper, loosely fitted, and aimed towards very young children. The price and loose-fitting nature of these blocks does make them quite a good pick for very small children.

At the end of the day, both blocks perform well in their own right. The choice that you have to make is if you are willing to pay more for the higher quality Duplos or if you prefer to save some money and buy the cheaper Mega Bloks.
