Writing guide

How to change the tone of your writing

Tone is not about what you say. It is about how it sounds when the reader hears it. This guide breaks down the 4 dimensions of writing tone with before-and-after examples for each.

5 min read

Formal ↔ Casual

One end

I am writing to inform you that the quarterly review has been rescheduled to March 28th.

Other end

Heads up, the quarterly review got moved to March 28th.

How to shift: Contractions, shorter sentences, and first-person pronouns make text more casual. Removing them makes it more formal.

Confident ↔ Tentative

One end

I recommend we proceed with option B.

Other end

I was wondering if maybe we could possibly consider option B?

How to shift: Hedge words (maybe, perhaps, sort of, I think) make writing tentative. Cut them for confidence. Add them deliberately when genuine uncertainty matters.

Warm ↔ Neutral

One end

Great work on the presentation! The client loved it.

Other end

The presentation has been reviewed. The client responded favorably.

How to shift: Exclamation marks, emotional words (great, loved, excited), and direct praise add warmth. Removing them creates professional distance.

Concise ↔ Detailed

One end

Ship by Friday.

Other end

To ensure we meet the client deadline of April 2nd, I would like the team to complete and ship the updated feature set no later than end of day Friday, March 28th.

How to shift: Concise is not always better. Use detail when the reader needs context. Use brevity when the action is clear.
