Resume Formatting: Margins, Font Sizes and Spacing That Actually Work

Formatting is where people go when the writing is hard. It feels productive — the page visibly changes — and it is the least likely part of the process to improve your chances.

That said, bad formatting genuinely costs you, in two specific ways: it makes the document tiring to read, and it can break text extraction entirely. So here are the working numbers, and then the part that matters more, which is what to do when the content will not fit.

The numbers

| Element | Range | Notes | |---|---|---| | Margins | 0.5"–1" (13–25mm) | 0.75" is a safe default on all four sides | | Body text | 10–12pt | 11pt suits most typefaces | | Your name | 14–18pt | Bold, plain text, not an image | | Section headings | 12–14pt | Bold or small caps; consistent throughout | | Line spacing | 1.0–1.15 | Within paragraphs and bullets | | Space between sections | 8–12pt | The single biggest readability lever | | Bullet indent | 0.15"–0.25" | Enough to register; more wastes width |

Two of those have hard floors. Do not go below 10pt body text — it is the point at which a document stops being comfortable for a reader in their fifties, which describes a large share of hiring managers. And do not go below half-inch margins, because some printers clip beyond that and the page begins to feel like a wall.

Everything else is preference. A resume at 11pt with 0.75" margins and a clear gap between sections will look professional in any industry.

Spacing is the part that matters

If you change one thing, change the space between blocks rather than within them.

Most cramped-looking resumes have adequate line spacing and no separation between sections, so the eye cannot find where "Experience" ends and "Education" begins. The reader has to parse the structure instead of absorbing it, and on the fifteenth resume of the morning they will not.

Give every section a consistent gap above it — 10pt is a reasonable number — and give each job entry a smaller but visible gap. The page will feel lighter without losing a single word.

The corollary: be consistent. Two sections with 12pt above them and one with 6pt reads as sloppiness even when nobody consciously registers it. Most word processors have paragraph spacing settings that do this properly; adjusting by pressing Enter twice does not, because the amount varies with font size.

Typefaces

Any clean, widely-installed typeface at a sensible size is fine. Serif or sans-serif does not matter and never has.

Reliable choices: Calibri, Arial, Helvetica, Cambria, Georgia, Garamond, Lato, Source Sans. Pick one and use it for the entire document. A second face for headings is acceptable if you are confident about pairing, and unnecessary otherwise.

The genuinely bad choices are narrow:

• Display and script fonts. They slow reading and frequently fail to embed.
• Anything below 10pt, for the reason above.
• Fonts that live only on your machine. If the font does not embed in the PDF, the reader gets a substitute and your line breaks move — which is how a carefully fitted one-page resume arrives as a page and a half.
• Comic Sans. Still true.

Garamond deserves a specific note: it runs visually small for its point size, so 11pt Garamond reads more like 10pt in something else. If you use it, go to 12.

Structure, and why it is not just aesthetics

Formatting decisions determine whether a parser can extract your history. Three rules carry almost all of the risk:

One column. Two-column layouts are extracted in the order the text exists in the file, which is not the order your eye follows. That can attach dates to the wrong employers or produce a run of dates with nothing connecting them to anything.

Nothing important in headers or footers. Many parsers skip these regions entirely. If your name and phone number live in the header, the resulting record may have no contact details at all. Page numbers are fine there; contact information is not.

Real text, not images. A name rendered as a logo, contact details as icons, or a whole resume exported as an image parses as nothing. Select the text in your exported PDF with the cursor — if you cannot, neither can the software.

Beyond those three, there is more design room than the advice usually implies. Horizontal rules, restrained colour on headings, small caps, generous whitespace, and clear hierarchy all survive extraction perfectly well.

Section order

Standard, boring, and in this order for most people: contact, summary, experience, education, skills, then anything else.

Two exceptions. Early career puts education above experience, because it is the stronger material. Career changers and technical candidates often put skills above experience, because that is the part that translates.

Use conventional section names. "Experience", "Education", "Skills", "Certifications" are parsed reliably because parsers are looking for exactly those words. "Where I've Made an Impact" is a nice heading and a parser has no idea what it contains.

When it does not fit

You are a quarter-page over. The temptation is to drop to 9.5pt, pull margins to 0.4", and squeeze line spacing to 0.9.

Do the opposite. Work down this list in order:

1. Cut a weak bullet. There is one. Usually there are three — the duty descriptions that survived the last edit.
2. Compress old roles. Anything more than eight years back rarely needs more than two lines. Anything more than fifteen years back can be a single line of title and company.
3. Remove filler sections. "References available on request", an objective that only states what you want, hobbies that are not relevant, proficiency bars.
4. Tighten the wording. "In order to" becomes "to". "Was responsible for managing" becomes "ran". This routinely recovers three or four lines.
5. Then, and only then, adjust the layout — and only within the ranges above.

The order matters because every step before the last one improves the resume, while the last one only makes it fit. A dense, airless page is a worse document than a clean two-page one, and reviewers notice compression immediately even when they cannot name what is wrong.

Export

PDF, unless the posting explicitly asks for .docx. It preserves your layout on every machine; a Word file re-flows according to the reader's fonts and settings, which can put a page break through the middle of a job.

Name the file properly — Firstname-Lastname-Resume.pdf. It appears in the recruiter's file list and often inside their tracking system, and resume_final_v4.pdf is the first thing they read about you.

Then run the check that matters: open the PDF, select all, paste into a plain text editor, and read what comes out. If your job titles still sit above their bullets and your dates are attached to the right employers, the formatting works. That test takes a minute and tells you more than any amount of adjusting.
