Have you ever considered designing a LEGO city, building, or scene? Discover which scale is right for you when building your own MOC (my own creation)!

Microscale (<1:50)

LEGO Microscale is defined as any scale smaller than Minifigure scale. The term covers a wide variety of scales, so we’re going to highlight several below.

Nanoscale (<1:1800)

Nanoscale is best suited to replicate large cityscapes. Typically, buildings are a few stud wide, and floors are represented by alternating solid color and transparent plates.

Within Microscale are 1:650 scale buildings, which are intricately designed and popularized by Spencer Rezkalla and more recently Rocco Buttliere. This scale is perfect for replicating famous landmarks, which are large enough to include Technic cores for difficult angles and nice parts usage.

Micropolis Scale (1:288)

TwinLug created the Micropolis standard around 2010, though the scale predates the group. With a 16×16 stud module equal to a quarter of a city block, builders worldwide can create their own buildings and seamlessly integrate them at LEGO events. Micropolis is typically the largest scale to exclude figures.

Trophy Fig Scale (1:130)

Mini Modular / Four-Plate Fig Scale (1:120)

Four-plate and trophy figs are the smallest recognizable figures in LEGO. Building in these scales requires interesting parts usage to achieve windows, doors, vehicles, and other details.

Baby Scale (1:100)

The first known Baby Scale city was created by Paul Wellington in 2023. Less than half the size of Minifigure Scale, Baby Scale builds provides ample opportunity for detail in a quarter of the space.

Microfig Scale (1:80)

Microfigs are slightly larger than LEGO babies but around half the size of Minifigures. Similar to Baby Scale, Microfig Scale is great for building with a lot of detail.

Minifigure Scale (1:42)

Minifigure scale is the most popular LEGO scale in the world. With a plethora of officials sets, figures, and details, it’s easy get start a build from scratch or expand on an existing MOC.

Minidoll Scale (1:38)

The LEGO Friends series is most common in Minidoll Scale. These figures are slightly larger than Minifigures, leaving room for a little more detail in builds.

Miniland Scale (1:17)

Few builders create buildings in Miniland scale due to the shear number of pieces involved. This scale is great for small MOCs and vignettes, but you explore entire Miniland skylines at LEGOLAND resorts across the world.

Life Size (1:1)

What does it take to build a life size LEGO house? In 2009, James May and over 1000 volunteers assembled 3.3 million bricks to build a real LEGO house. Unless you have a nearly unlimited supply of bricks and cash, it’s best to stick to smaller scales.
