How to choose a scale for a LEGO MOC and convert real measurements into studs and plates, with the arithmetic for minifigure, micro and jumbo scale and current official sets that show each one.
Scale is the first decision in any LEGO MOC, because it sets how big the model gets, how much detail fits and which parts you need. Choose the scale from the subject, then do the arithmetic once so every part of the model agrees. Here is how, with the numbers.
The numbers you need
LEGO's system rests on three measurements: studs sit 8 mm apart, a plate is 3.2 mm tall and a brick 9.6 mm, three plates. A minifigure is about 4 cm tall. With those, any scale works out with a calculator:
- Length in studs = real length ÷ scale ÷ 8 mm.
- Height in plates = real height ÷ scale ÷ 3.2 mm.
For example, a 4.5 m car at 1:44 is about 102 mm long, about 13 studs. A 3 m ceiling at the same scale is about 68 mm, or about 21 plates, seven bricks.
Minifigure scale: for things figures use
At about 4 cm tall, a minifigure stands in for a 1.75 m adult at roughly 1:44. The catch is width: minifigures are wide for their height, so buildings and vehicles built to strict scale are too narrow for them. Builders, and LEGO, widen things on purpose: LEGO's Speed Champions cars moved from six to eight studs wide in 2020, which leaves room for two figures side by side. Plan doors and interiors around the figure, not the tape measure.
The official Modular Buildings are the reference for minifigure-scale architecture. Prices, piece counts and expected exit dates come from our catalog when this page loads.

Micro scale: landmarks and skylines
At micro scale a whole building is a few studs wide, so details become single parts: a 1x1 round plate is a window, a cheese slope a roof, a grille tile a facade. The challenge is choosing what to leave out. LEGO's Architecture sets are the best study material, and the Star Wars Starship Collection shows a middle step LEGO calls mid scale. Our microscale guide covers the techniques.

A fixed real-world scale also works for display models. LEGO's Titanic is a 1:200 model built in three sections, about the clearest official example of picking a scale and keeping to it.

Jumbo scale: one small thing, made big
Jumbo scale turns a small object, most often a minifigure, into a display piece. The difficulty flips: instead of finding parts small enough, you need curves and smooth surfaces at a size where every step in a slope shows, so builders lean on curved slopes, tiles and sideways building. LEGO's Up-Scaled minifigure sets are the official version.

Mixing scales on purpose
Building the background of a scene at a smaller scale than the foreground makes it look deeper than it is. Our forced perspective guide shows how.
