I have invented the first ruler in KidBlock! Now when you need others to know how long or tall something's needs to be, use this! You can make the ruler from 1 block to 1,000, or more! As many as you need. (As long as it doesn't take up the whole world.) If you download this world you can get a closer look. Also, you can explore the rest of the world me build what ever you want! You can measure your creations with the ruler! Enjoy!
