2 inch high item - help with the math!

I use this, and then I use set focus.

No-Math Focus Ruler

Leveraging the recently-released Set Focus tool, I’ve designed a tool to help place materials when the crumb tray has been removed, no maths required. If your material is between the lines while resting on the bottom of your GF – not the crumb tray, you should be able to use Set Focus in the UI. If the top of your material is below the bottom line, use your favorite method (sheets of PG, tiles, 3-D printed stands, matching sets of trained hedgies, etc.) to elevate it and recheck. Repeat until …

Wait, is your crumb tray in? Sorry, I guess I’m not following. I usually use that ruler to make sure my material is in the right position to use set fous. If you use set focus, you don’t need to enter the material thickness…unless set focus can’t figure it out.
