Count blocks for solid boxes, room shells, walls, floors, and circular walls using explicit outside dimensions.
How to use this tool
Choose a supported design and enter its outside dimensions. Enter the exact number of blocks you will remove for openings. The result gives building blocks and a stack-of-64 breakdown.
What each design includes
A solid box fills every block in its width, depth, and height. A closed room has a one-block shell, including the floor and roof. Walls leave the floor and roof open. A floor is one layer. A circular wall uses the pixel circle generator's outline, repeats it through the chosen height, and leaves both ends open.
Corners and openings
Outside dimensions include the walls. The shell formulas count shared corners once. Removed blocks represent exact empty positions for windows, doors, or other openings; they do not infer an architectural design. The stack breakdown assumes blocks stack to 64. Select your exact material in the storage calculator when its stack size differs, and use the crafting planner to turn block totals into recipe ingredients.
FAQ
Are dimensions inside or outside?
Outside. A one-block wall reduces the interior width and depth by two where an interior exists.
Does a room include a roof?
Yes. The room design includes a floor, roof, and walls. Choose walls for an open shell.
Can it calculate decorative builds?
It supports the listed geometric designs. Decoration and custom shapes need their own measured block counts.
