The Masgrimes Lining Triangle elevates a tool that’s been around for over a century, offering modern improvements inspired by historic designs. Created by American penman and historian David Grimes, this minimalist tool reimagines vintage classics like the Soennecken Rundschrift-Maass and the Ames Lettering Guide. The result? A more intuitive, versatile solution that belongs in every serious calligrapher’s toolkit.
Key features include:
Try combining different holes to develop custom guideline schemes, prop the triangle on a corner to ink crossbars on minuscule t’s, or rotate it to the top angle to create 73° slant lines for a more upright script style. The possibilities are truly endless.
Why you’ll love it:
**The Lining Triangle arrives with protective films on both sides to prevent scratches or chips during transit. Peel off both films before your first use for optimal clarity and performance.**

This little triangle is brilliant! I love how easy and intuitive it is to use. The instructional video is super short and contains all you need to know. I LOVE how the first hole in each row is the same #mm away from the bottom so you can go right from your bottom ruler line to whatever your x-height needs to be - this makes it really helpful you’re stacking several sets of lining. It’s super compact and portable so it’s easy to take with you. And I love love love how affordable it is. I have spent much more on a lining template that was less practical. This one is travel-ready as well!
