Great quality! As a graphic design student I really recommend it!

As a proofreader, I like this clear ruler that tells me the height of each letter in picas, the amount of space between lines (the leading), and other vital measurements. Kinda makes you feel "like an expert" to have it handy in your pencil cup when helping someone evaluate their document!

Excellent product easy to use.

EXCELENTE PRODUCTO

This types of rulers used to be easily available and this is the only one I could find. It is a good size... not too big and it has lots of leading space sizes, font sizes, inches and cm. Perfect.
