British vs. American vs. Australian English: Which One Should You Use?

If you’ve ever hesitated before typing colour or color, or wondered whether it should be organise, organize, or something in between—you’re not alone. One of the most common questions I get as a proofreader is:

“Should I use British, American, or Australian English?”

The short answer? It depends. Let’s break it down.

What’s the Difference?

These three English variants share a common base, but there are differences in spelling, punctuation, grammar, and vocabulary. Here’s a quick comparison:

American English	British English	Australian English
color / organize	colour / organise	colour / organise
traveled / labeled	travelled / labelled	travelled / labelled
program (computer)	program	program
program (TV show)	programme	program
check (banking)	cheque	cheque
center	centre	centre
favor	favour	favour
catalog	catalogue	catalogue
eggplant	aubergine	eggplant
cookie	biscuit	biscuit or cookie (or bikkie)
flashlight	torch	torch
soda / pop	soft drink / fizzy drink	soft drink
bell pepper	pepper	capsicum

Australian English typically follows British spelling and grammar rules but incorporates its own informal language and slang.

Other English variants, such as Canadian, South African, and New Zealand English, also exist. I don’t typically proofread in these styles as I’m less experienced with their specific conventions.

So... Which one should you use?

There’s no universal right or wrong—but consistency is crucial. Here’s how to decide:

1. Consider Your Audience

Writing for a global audience? Keep in mind that the USA has the largest English-speaking audience, so many non-American authors choose to write in American English to appeal to that market.

1. Match the Setting and Characters

The language should reflect the world of your book. If your story is set in Melbourne, your narrator probably drinks lemonade, not soda, and wears trackies, not sweatpants. Regional language helps bring authenticity to your writing.

It’s perfectly fine to write in a variant that isn’t your native style. For example, a Kiwi author writing a novel set in New York would be better off using American English throughout.

1. Follow Submission Guidelines

Whether you’re submitting to a publisher, university, or agent, always check their language preferences. They may require a specific English variant, especially if they serve a global or region-specific market.
