Exact placed blocks
The estimate comes from the displayed voxel roof, not from a rough area formula.
Gable roof
Drag the row slider to inspect how the roof changes from one end of the building to the other.
Design a buildable roof for a rectangular Minecraft house. Choose the style, footprint, rise and overhang, then inspect the complete 3D roof, front profile and every construction row with an exact material count.
Drag the row slider to inspect how the roof changes from one end of the building to the other.
Many roof planners draw one gable end and multiply that profile by the building length. This generator models the actual roof surface, including hip-end tapering, ridge length, even-width alignment and overhangs.
The estimate comes from the displayed voxel roof, not from a rough area formula.
See the finished form, verify the front silhouette, then inspect individual rows.
Compare gable, hip, shed, gambrel and curved options without re-entering dimensions.
Enter the outside width and length of the building, excluding the roof overhang.
Set a roof style and rise. Odd widths produce a single centre ridge; even widths produce a two-block crest.
Start at Row 1 and copy its front-to-back cross-section. Move the slider after each completed row.
Join the top blocks last. Stairs can soften the visible slope; full blocks preserve the exact blueprint.
The best roof is determined by the footprint and the mood of the build, not by one universal pitch. Use the same dimensions above to compare silhouettes before committing materials.
| Style | Best for | Build note |
|---|---|---|
| Gable | Houses, halls, workshops | Fastest to build and easiest to extend |
| Hip | Villas, temples, large homes | Slopes inward at both ends; follow every row |
| Shed | Modern builds, lean-tos | One continuous slope with no centre ridge |
| Gambrel | Barns, stables, storage lofts | Steep lower slope and shallow upper slope |
| Curved | Fantasy halls, hangars, greenhouses | Works better at larger widths and rises |
For a typical house, a rise around one-third to one-half of the building width gives a readable roof without overwhelming the walls. A tall A-frame look uses a rise close to half the width or more. Broad medieval halls often look better with a medium rise and a one-block overhang. Curved roofs need extra width because a small arc quickly collapses into a stepped triangle.
The blueprint counts full grid positions so the geometry stays unambiguous. You can replace exposed slope blocks with matching stairs and use slabs to smooth a half-step or cap a flat ridge. Keep full blocks underneath wherever mobs, snow, lighting or interior sealing matter. The copied plan reports voxel positions; decorative stair orientation remains your design choice.
A barrel-style curved roof bends across the width and repeats along a rectangular building. A dome curves in two directions over a round footprint, so it needs different geometry. Use the Minecraft Dome Generator for observatories and glass domes. For the supporting round wall, start with the Circle Generator. This separation keeps each blueprint accurate and prevents a tower cap from being treated like a house roof.
The total updates from the blocks visible in the current model. Overhang blocks are included. On a hip roof, the shortening end rows are counted individually rather than assuming every row matches the middle. The stack conversion divides the exact total into stacks of 64 plus the remainder, which is useful when loading shulker boxes or planning a survival resource run.
Measure the wall footprint, add a one-block overhang, choose a rise that suits the scale, and mirror the slopes from both eaves. Build the ridge last so small alignment mistakes are easy to correct.
Yes. Both the displayed outside bounds and material total include the selected overhang. Building width and length refer to the walls underneath.
Yes. It creates a visual block-by-block reference and does not depend on commands, mods or a particular edition.
Most gable rows repeat, which makes them quick to build. Hip rows change near both ends, so the row view becomes especially useful there.
No. A curved roof repeats one arched profile along a rectangular building. A dome curves across both axes and belongs on a circular base.
