Styles Fight Back
A colleague formatted a 40-page report by selecting each paragraph and setting font size 11, spacing 1.15, and 6 pt after. Headings were made bold and enlarged manually. Your manager now asks for all body text at 12 pt and headings at 16 pt, and wants a consistent look throughout. You try selecting all (Ctrl+A) and changing the font size, but the headings also change and several paragraphs keep odd spacing. One paragraph refuses to match the rest no matter what you select.
1. Why does changing the font size on the whole document also change the headings, and what is the better approach?

Direct formatting applied to every paragraph means Ctrl+A treats body text and headings identically, so one font-size change hits both. The robust fix is to assign styles: body paragraphs get Normal (or Body Text), headings get Heading 1/Heading 2. Then modify the style definition (right-click the style > Modify) so Normal is 12 pt and Heading 1 is 16 pt. All styled paragraphs update at once, and future edits stay consistent.
2. One paragraph will not match the rest. What are likely causes and how do you diagnose it?

Likely causes are leftover direct formatting, a different paragraph style, or manual line breaks/spacing. Show formatting marks (pilcrow button) to reveal breaks and extra spacing, and use the Styles pane to see which style the paragraph uses. Clear direct formatting (Ctrl+Space for characters, Ctrl+Q for paragraph) then reapply the correct style. If it still differs, check paragraph spacing settings in the style itself rather than on the paragraph.
3. After restyling, the document grows from 40 to 46 pages. Is that a problem, and what would you check?
Read the worked answer
Growth is expected when body text goes from 11 to 12 pt and headings enlarge, so page count alone is not an error. Check that the increase is consistent, that no table now splits awkwardly, and that the TOC (if present) is updated. If a specific section ballooned disproportionately, inspect for a stray page break or a paragraph with excessive spacing rather than assuming the style change is wrong.
