One Page Isn’t a Target, It’s a Ceiling You Shouldn’t Reach
Almost every cover letter should fit on one page, and the useful version of that rule is stronger: most should fit comfortably, with white space left at the bottom. A letter that fills the page to the last line is usually a letter that was allowed to run.
There’s a number worth anchoring to. Resume Genius’s survey of 625 US hiring managers found that among those who read cover letters, the preferred length is around 400 words — three or four short paragraphs (Resume Genius, 2023 hiring manager survey). On a standard page with normal margins, 400 words occupies roughly two-thirds of the available space. The remaining third isn’t wasted; it’s the visual signal that you edited.
The Four Things That Push a Letter Over
When a cover letter spills onto a second page, it’s nearly always one of these — and none of them are “I had too much to say.”
| Cause | What it costs | Fix |
|---|---|---|
| A paragraph summarising your resume | 80–120 words | Delete it entirely. The resume is attached |
| The sourcing sentence — where you saw the posting | 15–25 words | Delete. Nobody is tracking attribution through your letter |
| A list of personal qualities — hard-working, detail-oriented, team player | 40–70 words | Delete. Unverifiable assertions; your example either demonstrated them or didn’t |
| An oversized header or signature block | Up to a quarter of the page | Keep contact details to two lines. Don’t repeat your full address if it’s already on the resume |
Remove all four and a letter that was running to a page and a half lands at about 300 words with room to spare. Notice that none of the fixes involve shrinking the font or the margins — those are the two things that make a letter look crammed, which is the exact impression the one-page rule exists to avoid.
Setting body text below 10.5pt, cutting margins under 2 cm, or reducing line spacing to 1.0 will technically fit the letter on one page and will visibly read as a document that was squeezed. A reader can tell the difference between a letter that was written to length and one that was compressed to length, and the second one implies you couldn’t decide what mattered. Cut a paragraph instead.
What 400 Words Actually Looks Like
Here’s the whole letter at the target length, with the proportions marked. The opening is two sentences, the evidence paragraph carries most of the weight, the bridge is short, and the close is two lines.
A complete one-page letter
Dear Ms. Arbuthnot,
I’m applying for the Programme Manager role at Keldon Energy. Your posting describes a portfolio that’s grown past the point where spreadsheet reporting works — that’s the situation I spent most of last year inside.
At Fernhill Utilities I owned a nine-project capital programme, roughly £31m, reporting to a board that had lost confidence in the numbers after two consecutive overruns. The reporting wasn’t the real problem; the real problem was that project managers were forecasting optimistically because nobody had ever been thanked for flagging a slip early. We changed what got reported before we changed how. Within two quarters the forecast variance at month-end dropped from an average of 14% to under 4%, and the board stopped asking for ad-hoc reviews because the monthly pack had become trustworthy.
What carries over to Keldon is less the tooling than that sequence. Reporting systems don’t fix forecasting culture, and installing one first tends to produce very precise numbers that are still wrong. I’d want to understand how your project managers currently get treated when they bring bad news early, because that answer usually determines how long the rest takes.
I’d welcome a conversation about the role. Thank you for your time.
Best regards,
Tomas Lindqvist

That’s 290 words — under the preferred length, and there isn’t a sentence in it you could remove without losing something. Length is the output of editing, not a target you write toward.
The Mechanics of Fitting, Done Properly
If the letter is close and you want it to land on one page without compressing it, the adjustments below are the ones that don’t show. Make them in this order, and stop as soon as it fits.
| Adjustment | Safe range | Gains you |
|---|---|---|
| Cut a sentence from the body | Always first | 1–2 lines, and usually improves the letter |
| Reduce space above the greeting | Down to about 24pt | 2–4 lines |
| Contact details on one line instead of stacked | Always safe | 2–3 lines |
| Line spacing | No lower than 1.15 | 2–4 lines |
| Margins | No tighter than 2 cm / 0.8 in | 3–5 lines |
| Body type size | No smaller than 10.5pt | Last resort only |
The order matters. People reliably reach for the last two first, because they’re the fastest, and they’re the two a reader can see. A letter at 9.5pt with 1.4 cm margins announces that the writer had too much to say and no way to decide what mattered.
How Length Shifts With Seniority
The 400-word figure is an average across all applications, and the right length moves with the role.
- Entry level and internships: 200–300 words. You have one piece of evidence; stretching it is visible. See our entry-level cover letter templates.
- Mid-career: 300–400 words. One strong example, properly told, plus the bridge to this role.
- Senior and specialist: 350–450 words. Two examples become defensible because the reader is assessing a pattern rather than a single result.
- Executive and board: 450 words to a full second page, where the evidence genuinely requires it — our executive cover letter templates cover that structure.
- Email applications: 150–200 words regardless of seniority, because the medium decides rather than the role.
Across all of them, the test is the same and it isn’t a word count: could you remove a sentence without losing an argument? If yes, the letter is too long whatever the number says.
The Narrow Case for Going Over
Two pages is defensible in a small number of situations, and worth knowing so you don’t cut something that needed saying:
- Executive and board applications, where two or three pieces of evidence and a judgment paragraph genuinely need the room — the structure for those is covered in the seniority section above.
- Academic applications, where the letter often doubles as a research and teaching statement and has conventions of its own.
- Public-sector applications that ask you to address numbered selection criteria. Follow their structure, not this page’s.
- Anywhere the posting specifies a longer length. Their instruction beats every general rule.
Outside those, a second page is almost always the resume-summary paragraph wearing a disguise.
All Twelve Fit on One Page
Every template in the set is built around a single page with the body starting high, which is the structural half of the problem — a header that eats the top third forces the letter down before you’ve written a word.
A few are better suited to the shorter end. Ravenna, Verona, Bergen and Lisbon are the plainest and leave the most room, so a 250-word letter in any of them reads as deliberate rather than thin. Turin, Bruges, Nice and Seville carry formal headers and rules that balance a fuller letter nearer the 400-word mark. Malmo and Porto use large display names, which look best with a letter substantial enough to balance them. Vienna and Helsinki both run a second column or sidebar, which absorbs your contact details and gives the letter body more of the page than it would otherwise have.
Wensa’s templates are designed by our founder and product design team — Artur Lopato has 9+ years of experience designing digital products. Every Wensa template is shaped around what hiring managers and recruiters actually look for when scanning a cover letter in seconds — which is why none of the twelve spend the top third of the page on a letterhead.
If brevity is the point rather than a constraint, our minimalist cover letter templates are designed around a shorter letter. And the paragraph-by-paragraph structure behind the example above is in our guide to writing a cover letter.
FAQ — One-Page Cover Letter Templates
How long should a cover letter be?
Around 400 words is what hiring managers report preferring, which is three or four short paragraphs and roughly two-thirds of a page. Shorter is fine if nothing is missing; longer needs a specific reason.
Should a cover letter fill the whole page?
No. A letter that reaches the bottom margin reads as one that was allowed to run. Leaving the last third empty is a visible signal that you edited, and it costs you nothing.
What should I cut to fit one page?
The paragraph summarising your resume, the sentence saying where you found the posting, and the list of personal qualities. Those three together are usually 150–200 words and none of them tell the reader anything actionable.
Can I reduce the font size to fit one page?
Don’t. Body text below 10.5pt, margins under 2 cm or single line spacing all read as compression rather than concision, which is the opposite of what the one-page rule is for. Cut a paragraph instead.
Is a two-page cover letter ever acceptable?
In four situations: executive and board applications, academic applications where the letter doubles as a research statement, public-sector applications addressing numbered selection criteria, and any posting that explicitly asks for more. Otherwise, no.
What should I adjust first if my letter is slightly too long?
Cut a sentence. Then reduce the space above the greeting, put contact details on one line instead of stacked, and only then touch line spacing or margins. Font size is the last resort, because it’s the change a reader can actually see.
Does the right length depend on seniority?
Yes. Entry level runs 200–300 words, mid-career 300–400, senior 350–450, and executive applications can justify more. Email applications stay at 150–200 regardless, because the medium decides rather than the role.
What’s the minimum safe margin for a cover letter?
2 cm, or about 0.8 inch. Below that you risk clipping if anyone prints it, and the page starts to look crammed — which is exactly the impression the one-page convention exists to prevent.
Does the one-page rule apply to email cover letters?
It’s stricter there. An email cover letter runs about 150–200 words, because it’s read in a preview pane rather than on a page — see our email cover letter templates.
How many paragraphs should a one-page cover letter have?
Three or four. An opening that names the role and one specific thing about the employer, one paragraph of real evidence, a short bridge connecting it to this job, and a two-line close.
