Printable Rulers In Actual Size
The convenience of a printable ruler is something that I've taken advantage of more times than I can remember. I'm frequently misplacing my rulers and measuring tape and the quick print of a free printable ruler gets me going in quicker time than it would take to hunt down the actual ruler.
The printable rulers are in just about every different form imaginable including rulers in actual size to measure feet, centimeters, inches, and metric measurements. There are your standard rulers but also rulers such as protractors, growth charts, and French and hip curve rulers.
Printable rulers are also very convenient because they are more flexible than a plastic, wood, or metal ruler because you can bend them to measure just about anything.
If you're teaching your child or students about units of measurements then these printable rulers can really help with that and with them being paper, they can even decorate them to make the activity a bit more fun.
These rulers are actual size so you'll want to take care to keep them that way when you print. When printing a paper ruler make sure that you do not have the shrink to fit option turned on, and page scaling should be set to none before you print. This will print the ruler at actual size with accurate units.
If you're looking for a sturdier printable ruler, try printing the ruler on cardstock instead of printer paper. You also might like this free, printable graph paper available.
