What to Consider Before Purchasing Legos

Legos aren’t like they used to be. With countless styles and designs, there are a few items you should consider before purchasing Legos. They include:

  • Age
  • Interest & Hobbies
  • Active vs. Model Sets
  • Colors
  • Price

Now, let’s take a closer look at each one.


Age is the first factor you should consider when purchasing Legos. Lego boxes are clearly marked with an age range. There will always be a starting age range (for example, seven years old).

In some cases, an age range will be listed (such as 7 – 12). In other cases, there isn’t a cap on age (such as 7+).

The good news? There’s a Lego set for just about everyone. Lego sets start for toddlers and go all the way up to adults of 99+ years old.

Interest & Hobbies

Nowadays, there’s a Lego set for just about every interest and hobby. Lego is continuously engineering new designs, and they even have contracts with movies and video games.

So, before you choose a Lego set for your boys, consider if they prefer a more creative approach with standard blocks or if they’d prefer to build Legos with a set theme.

Active vs. Model Sets

When it comes to function, consider whether your child will roughhouse their Lego set or if they’re looking for a more refined model that they can keep on a shelf.

Lego caters to both options, so it’s just a matter of knowing what will work best for your child.


The goal is to have your child playing a lot with their Legos. So, you’ll want to make sure to choose colors and designs that appeal to them. Picking a Lego set with attractive colors is especially important if you’ll be purchasing a general building set without a theme.

Lego has done a great job of offering various color options, so the most challenging part will likely be picking your child’s favorite.


As you may have already gathered from this article, prices for Legos vary significantly. Economical Legos start in the single digits to teens. The price range can go up into the hundreds of dollars, especially in detailed models with a high piece count.

So, decide how much you’re willing to spend on a Lego set and work from there.

Benefits of Legos

Legos are so much more than just a toy. Parents who have exposed their boys to Legos can likely attest that they are both fun and educational.

Below are six benefits of Legos for children:

  1. Develops fine motor skills
  2. Helps with spatial awareness
  3. Improves reading and learning to follow instructions
  4. Enhances concentration and patience
  5. Encourages problem-solving and mathematical thinking
  6. Promotes the development of planning skills

Mixing and Matching Lego Sets

As you may have gathered from this article, most Lego sets are designed to be mixed and matched.

But should you do it?

That depends.

Below are some advantages and disadvantages of mixing and matching Lego sets.


  • Near endless building opportunities.
  • Some Lego sets come with fewer pieces, making them feel incomplete without other Lego kits.
  • Your child will be able to build larger, taller designs.


  • If you want to rebuild an original set after mixing and matching, it can be a nightmare to sort out the pieces.
  • Buying multiple Lego kits can get expensive.

As a final note, most, but not all, Lego sets are compatible with other kits. For example, a toddler’s DUPLO bricks won’t be compatible with bricks from the Creator line.

To know whether or not your old Lego sets can be mixed and matched with the new kit you want to buy, simply read the box of your new Lego set.

Lego Instructions

Lego is well known for offering detailed, step-by-step building instructions.

If you happen to lose your instruction booklet, simply head to Lego’s website and search from the thousands they offer online. You can even download the Lego Building Instructions app to make it easier to source long-lost instructions for Technic sets.

Lego’s online instruction offers an additional benefit—alternative instructions for sets that can be built in various ways.

Are you unsure if your Lego set comes with alternative designs?

No problem. Simply type your set number into their system, and they’ll let you know.

Even if your set doesn’t come with different designs, it’s still worth checking out their website. You just might get inspired, especially if you have multiple Lego sets to mix and match.

Value of Legos

Legos may have originally started as only for kids, but over the years, they’ve developed styles and complexities that appeal to adults too. In either case, Legos can have both sentimental and monetary value for its owners over time.

Kits that turned into collector’s items have been known to sell for thousands of dollars when their retail value was in the hundreds. In fact, they went on to claim that Legos could be a better investment than stocks.

So, if your child outgrows their Lego set, you may want to tuck it in a safe place and hope its value increases.

Final Word

Legos are bound to bring joy and learning opportunities for the boys in your family. There’s a Lego out there for every child; they offer an array of designs, difficulty levels, colors, and uses.

What are you waiting for? Whether it’s your first Lego purchase or twentieth, take the leap and purchase that dream set for your child.
