- Spell out all numbers from one to nine; use figures for any number 10 or above, except at the beginning of a sentence. This includes ordinal numbers: first, 1st; 20th, not twentieth, unless it’s an official title or data point. Exception: numerical digits are fine when numbers one to nine are used in PowerPoint, designed collateral (e.g., posters, banners, infographics, data points, facts and figures, etc.) to enhance readability.
- The use of ordinals is fine in referencing a title or
proper name. Do not use superscript in ordinals (e.g., 20th, not 20th).
- Use figures for decimals or compound fractions.
- Numbers in the millions should be written out as a combination of words and figures.
- Use figures in sequences such as chapters, acts of a play, school grades, highways, etc.

- You can use the per cent symbol (i.e., %) in presentations, pictures and designed collateral (e.g., infographics, tables, images, data points, posters) when it helps enhance readability and clarity. Do not use symbols in body copy or long-form copy.
Note: The per cent symbol is allowed when averages and grades are referenced in Waterloo’s academic calendars.
- Do not repeat the per cent word or symbol when sharing a percentage range.
Examples: 75-98% (table or infographic),
75 to 98 per cent (body copy).
- To avoid ambiguity, write increased to 15 per cent from 10 (not increased from 10 to 15 per cent).
Examples: six per cent, 15 percentage points, five per cent increase (no hyphens).
