Welcome to Tim’s Printables, your go-to place for useful freebie printables and PDF downloads. On this page, I’m providing you with a printable inch ruler. Need a ruler but don’t want to spend time driving to the store? This download will remedy the problem. Better still, this printable inch ruler can be bent and used to measure curved surfaces just like a tape measure. So in that regard, a paper ruler is actually superior to a regular metal one. I’ve created the printable inch ruler in both color and black and white. Download whichever one will best suit your needs. Both come in PDF format. Be sure to uncheck “Scale to Fit” in your printer settings before pressing print, to prevent your ruler from printing out the wrong size.
