center finding ruler

I love rulers, but this one holds a special place in my warm little heart. About one half day of heavy use, and my brain was noticeably mushier. It doesn't take much to figure out how to use it. An example if it isn't readily apparent. Say I have two dots four inches apart and want to find the half way point between them. Place the ruler next to the dots so that one dot is left of the zero and the other dot is to the right. Using a bit of intuition move the ruler in the direction that balances the measurements on either side of the zero. In this example the left dot will be on the left 2" line, and the right dot will be on the right 2" line. The zero is the center point! Plus without doing any math the ruler shows that the center is two inches from either dot!! The ruler really earns its keep when it's 0200 in the morning, and the dots are 4 13/73" apart.

This is another one of my tools from the print studio. I used it mostly when setting the registration marks on paper before printing multiple runs. Paper didn't have to be the exact same size, but I always had a perfect center. Now it is stored with the book tools.


  1. oh wow. i've never seen this before. and now i don't think i can make anything more until i have one in my hands...

  2. This is so cool. Where do you get them?

  3. ah, yes. I ordered it directly from the manufacturer.

    I can't remember how I came across them. I think I saw one of their rulers in a store and researched the name to see what other kind of products they had.
