Occasionally, I have clients ask me to recreate a poster that they have from long, long ago. They want the fonts the same, photos etc. I have had posters, postcards, and business cards given to me. How do I know what size their fonts are. Well, I could go into math and create complex measurements after scanning at 100% and then measuring.
Or I could just use a ruler. Tiny Tutorials put together a great printable ruler for download. It’s awesome, and if you really want to do some folding you can make it into a 6 sided ruler. Awesome. Thank you to Tiny Tutorials.
