To Spell Out Numbers, or Not?

This month’s issue includes a short history of spelling out numbers and another great handmade sign.

Why We Spell Out Only Some Numbers

“I prefer writing numbers as numbers. Not as words. I find it easier to read.”

That was from a text message I received recently. (Yes, people know my love of language and send me stuff like this now and then.)

As this was from someone not in the writing field, I explained why sometimes numbers are spelled out, and sometimes they appear as figures. It depends on a lot:

How low or high the number is
If the numbers appears at the start of a sentence
Where you see it published (books follow a different style than news outlets)
What editorial style is being followed
And so much more! (The numerals listing in the AP style guide is over 1,500 words long.)

But why?! People in the industry know the rules. But does the reader? And if the reader doesn’t, why does it matter?

Consistency, Consistency, Consistency

It matters because of consistency. If each writer chose their own way of presenting numbers, they’d appear willy-nilly all over the place. And that’s bothersome for readers.

In an effort to create this consistency, style guides began over the last century implementing rules (guidelines, really) for how to present numerals in narrative. For a lot of publications, that means you’ll see numbers one through nine spelled out, with figures used for 10 and above.

Of course there are exceptions: ages, dates, measurement units, times, decimals, fractions…and the list goes on. Hence why AP’s numerals listing is so lengthy.

The good news is, when you work with a high-quality editor, you can leave your number questions to them. Good editors often have these nuances memorized, and when they don’t, they have the resources — and the passion — for finding the answers for you.
