How do I talk about numbers in English?

Dylan Nelson

Quick answer

You need four small words:

  • fromthe start
  • tothe end
  • bythe difference
  • inthe topic

Example: "Sign-ups went up from 200 to 300."

You talk about numbers all the time: sign-ups, time on task, errors. You know the numbers. The hard part is the small words around them. Get these four words right and people can follow your results easily.

The four small words

Look at the picture. Each word shows one part of the change.

9060 From = the start

"Time on task went down from 90 seconds..."

9060 To = the end

"...to 60 seconds."

500300200 By = the difference

"Support tickets went down by 200."

daily users In = the topic

"There was a big increase in daily users."

Try it first

Say this chart out loud in one sentence. Use from and to.

Up or down

You don't need many verbs. Choose one for each direction and use it often.

Going up

  • went up
  • increased
  • an increase in...

Going down

  • went down
  • dropped
  • a drop in...

Make it clearer

This is a very common first try. The numbers are right, but the small words make it hard to follow. How would you say it? Try first, then look.

A common first try

"The sign-ups increased in 100, from 200 until 300, so there was a big increase of users."

Say what the number means

A number alone doesn't tell people much. In a meeting, people think: "OK, so what?" Answer that before they ask. After the number, add one short sentence: why it matters.

1The number

"Time on task went down from 90 to 60 seconds."

2Why it matters

"So users finish checkout much faster."

3Next step (optional)

"Next, we want to test it on mobile."

To say why it matters

  • This means...
  • So...
  • That's important because...

When you're not sure yet

  • It's early, but...
  • We need more data, but so far...
  • It looks like...

It's OK to say you're not sure yet. It shows you understand your data.

Practice it

A warm-up and 8 quick charts. Fill the gaps, then say the full sentence out loud. Mistakes are normal here. Nobody is listening, so try again as many times as you like.

Activity5 minOpen full screen
Use it this week
  1. Choose one number from a project you're working on now.
  2. Write one sentence with from, to or by. Add one sentence about why it matters.
  3. Say it out loud before your next meeting.

Come back in 3 or 4 days and do the activity again. A second try, a few days later, helps you remember.

Questions designers ask

Is it "an increase of" or "an increase in"?

Both are correct. "Of" goes with the amount: "an increase of 100." "In" goes with the topic: "an increase in sign-ups."

Do I need to say both "from" and "to"?

No. "Sign-ups went up to 300" is fine if people know the start. For a new result, say both.

How do I talk about percentages?

Use the same small words: "Conversion went up from 2% to 3%." Giving both numbers is the clearest way.
