Head to head
LEGO DUPLO vs MEGA Bloks
The two toddler block systems every relative considers. The published age ratings are six months apart, and the maker is the bigger difference.
By Sawyer V. · Published
The short answer
Buy MEGA Bloks for a child just turning one, and DUPLO from eighteen months. MEGA publishes its First Builders bag at 1+ with 80 oversized pieces and a wheelbase. LEGO publishes the DUPLO Classic Deluxe Brick Box at 1½+ with 85 pieces — and DUPLO is LEGO’s own early-years line.

The arithmetic
Published specifications
| Maker | DUPLO: LEGO | First Builders: MEGA |
|---|---|
| Stated age | DUPLO 1½+ | MEGA Bloks 1+ |
| Pieces | DUPLO 85 | MEGA Bloks 80, in 10 shapes and 9 colors |
| Storage | DUPLO: brick box | MEGA Bloks: reusable bag |
| Extra in the box | MEGA Bloks: an attachable wheelbase |
| Brick size | DUPLO: larger than standard LEGO | MEGA Bloks: oversized for toddler hands |
| Where it leads | DUPLO: standard LEGO, same maker | MEGA Bloks: outgrown at four or five |
Six months apart
MEGA publishes 1+ and LEGO publishes 1½+. At the youngest end of the category, six months is a long time, and a published rating is a floor rather than a suggestion. A child turning one gets MEGA Bloks on the rating alone.
From eighteen months, both are rated for the child, and the question changes from “which is allowed?” to “which system do we want to be in?”
The maker is the real difference
DUPLO is LEGO’s own early-years line. For a family that expects to buy LEGO for years — and many do — starting with DUPLO keeps everything under one brand from the first birthday to the tenth.
MEGA is a different maker’s system. Neither LEGO nor MEGA publishes cross-compatibility with the other on the product pages we cite, so treat them as two separate collections rather than one that will merge.
What a toddler does with either
At one and two, mostly not building. A child this age knocks down the towers an adult builds, then gradually stacks two or three blocks, then presses them together. Both boxes do that job well; the blocks are big enough for small hands and forgiving enough for a toddler’s aim.
Worth knowing before you buy
Follow each published rating: MEGA Bloks 1+, DUPLO 1½+. An older sibling’s standard LEGO, rated 4+, is often the bigger hazard in a house with a toddler — keep it on a table rather than the floor.
So which one
Turning one: MEGA Bloks First Builders.
Eighteen months or older, with LEGO likely later: the DUPLO Classic Deluxe Brick Box.
Three, and the family wants wood: Lincoln Logs.
Say the unwelcome thing
Do not buy both
Two toddler systems from two makers means two half-collections. Choose on the age today and the brand you expect to be buying in three years, and put the money into more of one.
Where to go next
Building blocks for kids orders the whole block ladder by grip. The best LEGO sets for kids covers what comes after DUPLO, and STEM toys for 1 year olds covers the rest of that age.

1. Better from eighteen months
LEGO DUPLO Classic Deluxe Brick Box
LEGO · 10914 · maker rates it 1½+
85 DUPLO bricks in a brick box, from the maker whose standard bricks come next.
- Pieces
- 85
- Stated age
- 1½ and up
- Storage
- Supplied in a brick box
- Brick size
- DUPLO scale — larger than standard LEGO bricks
LEGO publishes the DUPLO Classic Deluxe Brick Box with 85 pieces, rated 1½ and up, supplied in a brick box, at DUPLO scale — larger than standard LEGO bricks — with nothing consumed.
The maker is the argument. DUPLO is LEGO’s early-years line, so a child who starts here moves on to standard LEGO from the same brand, and the family buys into one system rather than two.
The brick box is a small practical point in its favor. A rigid box that the bricks go back into survives a toddler household better than a bag.
Replay signal

- Open-ended — a box of bricks with no single model
- Does anything run out
- Nothing runs out
- Room to grow
- DUPLO is LEGO's early-years line, so the same brand continues into standard bricks
Why we say so: LEGO publishes 85 pieces rated 1½ and up. The DUPLO scale is the specification that decides it: bricks large enough for a toddler's grip, from the same maker whose standard bricks the child will move on to.
What’s wrong with it
Rated 1½+, six months later than MEGA Bloks.

2. Better at one
MEGA BLOKS First Builders Big Building Bag, 80 Pieces
MEGA · DCH62 · maker rates it 1+
80 oversized blocks in 10 shapes and 9 colors, with an attachable wheelbase, rated from one.
- Pieces
- 80, in 10 shapes and 9 colors
- Includes
- Reusable storage bag; an attachable wheelbase
- Stated age
- 1 and up
- Block size
- Oversized — designed for toddler hands
MEGA publishes 80 pieces in 10 shapes and 9 colors, a reusable storage bag and an attachable wheelbase, oversized for toddler hands, rated 1 and up, with nothing consumed.
A 1+ rating on a construction toy means the pieces are cleared for a child who still puts things in their mouth. That is why MEGA Bloks can arrive on a first birthday and DUPLO, on its published rating, cannot.
The wheelbase is a genuine extra. A tower that becomes a vehicle is a second game from the same box, and one a one-year-old understands.
Replay signal
- Open-ended or one-shot
- Open-ended, and at this age that is the entire point
- Does anything run out
- Nothing runs out
- Room to grow
- Outgrown at four or five, when the child's hands are ready for smaller bricks
Why we say so: MEGA publishes the 80-piece count across 10 shapes and 9 colors with a 1+ rating. A 1+ rating on a construction toy means the pieces have passed small-parts testing for children who still mouth things, which is the specification that matters most at this age and the reason most brick sets start at three.
What’s wrong with it
Outgrown at four or five, and it is a different maker's system from LEGO.
| Pieces | 80, in 10 shapes and 9 colors |

| Stated age | 1 and up |

3. The wooden step at three
Lincoln Logs 100th Anniversary Tin
Lincoln Logs · 100th Anniversary Tin · maker rates it 3+
111 real maple pieces joined by notches — the easiest wooden system for small hands.
- Pieces
- 111, real maple wood
- Contents
- Roof and roof facade pieces, wall logs, chimney, porch, fences, bonfire and bonfire seats
- Build ideas included
- 3 — a tall tower, two small houses with a bonfire, a large cabin
- Joining method
- Notched indentations; no clips, glue or connectors
Basic Fun publishes 111 real maple pieces joined by notched indentations with no clips, glue or connectors, three build ideas, rated 3+.
Where either brick system goes next if the family would rather add wood than more plastic. Notch-only joining needs no precision and no pressing.
Replay signal
- Open-ended or one-shot
- Open-ended after the three published ideas — notched logs impose a style, not a model
- Does anything run out
- Nothing runs out, and maple survives being trodden on
- Room to grow
- Limited by piece count rather than by concept; sets combine
Why we say so: Basic Fun publishes 111 real maple pieces joined by notches with no connectors. Notch-only joining is why a three-year-old can build with these: there is nothing to align precisely and nothing to press hard.
What’s wrong with it
Rated 3+, so it waits for the third birthday.

LEGO Classic Large Creative Brick Box
LEGO · 10698 · maker rates it 4+
The standard LEGO box, often bought for a toddler to grow into, rated 4+.
- Pieces
- 790
- Colors
- 33
- Stated age
- 4 and up
- Includes
- 8 types of windows and doors, 2 green baseplates, 6 tires and wheel rims
LEGO publishes the Classic Large Creative Brick Box with 790 pieces in 33 colors, compatible with all LEGO construction sets, rated 4 and up.
It is the right box at four. At one or two it is a box of small parts, and bought early it becomes an old thing from the cupboard by the time the child is ready. Buy DUPLO now and this later.
Replay signal
- Open-ended or one-shot
- Open-ended — this is the box with no instructions and no finished model
- Does anything run out
- Nothing runs out
- Room to grow
- Every LEGO set the child is ever given pours into the same box
Why we say so: LEGO publishes the 790-piece count, the 33 colors and the box's compatibility with all LEGO construction sets. The absence of a build-this model is the product's stated design, not an omission.
What’s wrong with it
Standard LEGO bricks are a small-parts decision in a house with a toddler.

We are not putting a buy button on this one. It is easy enough to find if you want it anyway — but we would rather send you to something that gets played with twice.
