Work out lego brick count instantly with clear inputs, formula shown and shareable results.
Each layer covers length times width studs, so bricks per layer is that area divided by the studs on one brick, rounded up; a standard brick layer adds 9.6 mm of height. Counting in studs rather than bricks is what lets you swap 2x4 for 2x2 pieces without redoing the plan, and the 9.6 mm layer height gives a real model size.
Bricks per layer
bricks per layer = ceiling(length studs x width studs / studs per brick)
Height
height = layers x 9.6 mm for standard bricks
bricks per layer = ceiling(length studs x width studs / studs per brick). Each layer covers length times width studs, so bricks per layer is that area divided by the studs on one brick, rounded up; a standard brick layer adds 9.6 mm of height.
Counting in studs rather than bricks is what lets you swap 2x4 for 2x2 pieces without redoing the plan, and the 9.6 mm layer height gives a real model size.
Enter model length, model width, number of layers, studs per brick. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
