LEGO DUPLO: Your Child's First LEGO Set

Published 18th November 2020

Considered a colourful staple of every toy box, the LEGO range has been helping foster youngsters’ imaginations for over 50 years. Twice the length, height and width of traditional LEGO bricks, these chunky building blocks are perfectly sized for tiny hands to handle - making them the ideal option for your little one’s first LEGO set. Which LEGO DUPLO box or set is best for your tot, you ask? Read on to find out!

The history of LEGO DUPLO

When LEGO DUPLO bricks were first introduced in 1969, the colour range was limited to red, yellow, blue and white - a far cry from the rainbow of shades today’s children are spoiled with! More colours were slowly added over the years, alongside different shapes like the small four-wheeled wagon and half arch. 

Deriving from the Latin word ‘duplex’, LEGO DUPLO bricks were scaled up to be twice the size of regular LEGO blocks. The minds behind this popular toy wanted the new, larger bricks to fit into the LEGO System in Play, so Godtfred Kirk Christiansen (a second generation LEGO Group owner) cleverly suggested the idea of hollow studs.

One of the first ever larger-brick sets to be released was the 510, aimed at younger children; it formed the beginning of the LEGO DUPLO box we know today. It wasn’t until the late 1970s, however, that the company decided to market LEGO DUPLO as a separate brand - bringing with it the birth of the famous red LEGO DUPLO bunny logo found on every LEGO DUPLO box today.

While LEGO DUPLO sets continued to evolve over the years, what remained constant was the desire for all the elements of the LEGO System to fit together and provide endless play potential for years to come.

Remaining true to its core, LEGO DUPLO sets continue to inspire young builders with new, innovative designs for the next generation and the same unlimited possibilities of the simple plastic brick. 

Today you’ll find LEGO DUPLO sets with a plethora of themes - from under-the-sea adventures, to fairground days out - and bricks in every colour imaginable: vivid pinks, sky blues, various shades of green (very important for distinguishing between shrubs, trees and lawns!) and browns, to name a few. 

Themed collaborations with Disney, Marvel and DC tap into the interests of today’s young architects, with LEGO DUPLO sets showcasing well-known characters and scenes from popular animations.

It can also be used to supplement an existing set with additional bricks to expand the realms of your little one’s imagination!
