Brick parts calculator
Type the size of a model in studs and see roughly how many bricks it takes. It is an estimate for planning a print or a shopping list, not an exact parts list.
Your model
Size when built-
Studs per layer-
Fewest bricks (2x4 only)-
Typical mix-
Most bricks (all 1x1)-
Rough plastic weight-
Estimate only. A real build also depends on colours, windows, stepped shapes and how the bricks overlap. The weight uses about 2.4 g for a 2x4 brick as a rule of thumb (about 0.3 g per stud); weigh one of yours for a better number.
How it works
- Brick-compatible sizes put studs 8 mm apart, so a model N studs wide is about 8 x N mm, minus a small gap.
- Hollow shell counts only the studs around the edge of each layer; solid counts every stud.
- The fewest-bricks figure packs each layer with 2x4 bricks, rounded up. The most-bricks figure is one stud per brick. A typical mix assumes bricks average about 3.5 studs each, which is a planning guess.
Want the exact parts for a real set? Type its number into the set tool and get every part with a print file. To turn the count into a cost, use the print cost calculator.
Printed bricks are not toys: small parts, a choking hazard, not for children under 3.
