What is the purpose of the holes in a standard ruler?

Question

I'm looking at a wooden ruler, and see 4 holes: 3 spaced evenly across the ruler, and a large one at the end. Is there any particular reason they're there?

Thanks, you guys. I guess I was having a stupid moment.

Answer 1

So you can put it in a binder

Answer 2

You might see whether the three evenly-spaced holes match the holes in a 3-ring binder. If so, then they're probably there to make the ruler easy to store with a student's math folder.

Answer 3

So you can keep yourself entertained in class with nice, evenly drawn circles. As for the spinning on pencils, the ruler tends to get taken away after it flies of and hits someone.

And to fit in binders.

Answer 4

yeah for putting the ruler in to a three ring binder or to hang it up on the wall (the big hole)

Answer 5

The three mid-size holes are so you can put it in your three ring binder. The big one is so you can hang it up or something of the sort.

Hope this helps!

Answer 6

So you can put it in a 3 ring binder

Answer 7

So you can put a string on it to wear around your neck in the event that you come across something you want to measure. And it's best to put a keyring in the hole then the string on the keyring. That will be the next thing rappers start wearing around their neck.

Answer 8

So the ruler can fit in your binder

Answer 9

so you can put in a standard 3 ringed binder

Answer 10

They are for fitting into a standard format binder.

Answer 11

So you can hold the ruler over your eyes, look thru the holes and yell "I CAN SEE YOU!"
