If you realllly get into it. Or if you’re into plant ID: you can tattoo a little ruler onto your hand. e.g., along your index finger. Makes it easy to get pictures of plants to scale.
The tattoo will eventually get a little inaccurate, but still seems like a good point of reference.

Adam savage has a ruler tattoo on his arm.
I have a leather bracelet that is a measuring tape when I remove it. Super handy.
It has gone out of whack by about a 16th of an inch over the last 5 years, but still very helpful for measurement that don’t need a lot of accuracy.
All slap bracelets are also measuring tape.
