Greetings! Tim’s Printables is the place to be if you’re looking for free high quality printables for work, school, or home. The freebie for this webpage is a printable centimeter ruler. If you need a ruler but can’t find one around the house, this download will save you a trip to the store. In fact, in some ways, this printable centimeter ruler is better than a plastic or metal one. A plastic ruler doesn’t bend, but a paper ruler bends just like a tape measure, allowing you to measure curved surfaces. The paper ruler is available in both color and black and white. Select the one that’s best for you.
Since most browsers have the ability to open PDF files, I’ve saved the printable centimeter ruler in PDF format. When printing, don’t choose the “Scale to Fit” option in your printer settings. Otherwise your ruler will not be to scale.
