Transparent Graph Rulers

These light-weight, flexible, transparent plastic rulers feature red grid markings that are easy to read on both light and dark surfaces and have zero-centering scales. With the exception of the metric ruler, they all have a 1/8" grid with a 1/16" graduated edge. The metric ruler has a scale of inches divided in 10ths on one side and has centimeter and millimeter graduations on the other.

The 24" graph ruler is calibrated in 8ths to the inch with a zero centering scale.
