About Block Build Tools

Block Build Tools makes free helpers for people who build in Minecraft, so big projects take less counting and guessing.

Tools so far: the circle generator for pixel circles and ovals, and the Nether portal calculator.

How we check the tools

Shapes are generated by code with automated tests, including hand-checked small circles and symmetry checks.
Game rules, such as the Nether's 1:8 scale and portal frame sizes, are read from the Minecraft Wiki and checked against a second source. Each page lists its sources.
Block colors on our charts are plain colors we chose. We don't use game textures, screenshots or logos.

Block Build Tools is a small independent website. Every tool is free, needs no account, and runs in your browser.

NOT AN OFFICIAL MINECRAFT PRODUCT. NOT APPROVED BY OR ASSOCIATED WITH MOJANG OR MICROSOFT.
