What’s the difference between a style guide and a tone of voice guide?

We’ve been asked this a couple of times this week, so here’s a quick overview:


This is the word that many organisations – and everyone working in writing and communications – use to describe a common approach to the nuts and bolts of presenting information. It includes the way your organisation spells words, capitalises words, uses punctuation and things like italics and bolding.

It will also set out how your organisation does things like write dates, quantities, addresses – and any other piece of written information you need to have a common approach for.

The very good reason to have a style guide is your written communications are more legible and easy to follow if you have a common approach to presenting information.

Typical advice in a style guide will be:

Style is about the physical appearance of information. Tone, on the other hand, is about conveying a distinct personality in words. So rather than simply concern itself with the layout of a date or the capitalisation of certain words, a tone of voice guideline will explain which words, phrases and constructions to use to achieve a particular personality.

A good tone of voice guideline will also explain how to flex a tone so that it works in all circumstances – from the most serious through to the most celebratory.

Advice in a tone of voice guideline may say something like this:

Do you need both?

Yes you do – because each guide performs different roles.
