Sometimes, when you’re out and about in the world, you may find that it would be really helpful to have a tape measure.
You could be like my mum, who carries a soft, lightweight tape measure like this one around in her purse and whips it out every time she needs to measure a random wall-hanging or outdoor chair cushion.
Or you could be like Reddit user u/buttpuckering (we don’t discriminate based on usernames) and try this:
For quick reference in the future, find and measure between two points on your hand/forearm to the closest inch.
Some examples: Left hand. Middle finger, 3". Tip of pinky to a mole on wrist, 6". Index finger to a mole on forearm, 12".
It helps out when quick, small measurements are needed and a ruler isn’t handy.
Thanks to this tip, I now know that the length of my middle finger to the top of my wrist is almost exactly 18cm, which means I soon will be (constructively) flipping off a bunch of inanimate objects.
