How long should a cover letter be? Short enough that a busy reader finishes it, long enough to carry one real piece of evidence: in practice, 250 to 350 words, comfortably under one page. That's the whole answer, and the rest of this article is the reasoning, the exceptions, and — most usefully — a demonstrated method for getting an overweight draft down to fighting weight, because almost nobody's problem is a letter that's too short.
The answer up front: 250-350 words, and why
The 250–350 range isn't arbitrary. It's the length that a four-paragraph letter naturally lands at when each paragraph does exactly one job:
- Hook: 2–3 sentences, roughly 40–60 words
- Proof story: 4–6 sentences, roughly 90–130 words
- Fit: 3–4 sentences, roughly 60–90 words
- Close: 2 sentences, roughly 25–40 words
Add a greeting and sign-off and you're at 250–350. Anything substantially over that range means a paragraph is doing two jobs — usually the proof paragraph telling two stories, or the fit paragraph drifting into a prose summary of your resume. Anything substantially under about 150 words usually means the proof paragraph is missing entirely, and the letter is all assertion, no evidence.
The one-page rule is the hard outer boundary, but treating "one page" as the target produces bloated letters — a full page single-spaced is 450–550 words, which is 40% more reading than the content justifies. Aim for the letter to fill half to two-thirds of the page with white space below. The visual signal matters: a dense full page announces "this will take a while" before the first sentence gets a chance.
If the structure behind those four paragraphs is unfamiliar, our guide on how to write a cover letter builds it from the ground up — this article assumes the shape and focuses on the size.
What recruiters say about length — sourced, not invented
We'll be straight with you: there is no rigorous, universal study establishing the optimal cover letter word count, and any article citing a suspiciously precise figure ("letters of 287 words get 34% more interviews") is decorating a guess. What actually exists is a broad, consistent pattern in what recruiters and hiring managers say publicly and tell candidates directly — in career Q&As, hiring blog posts, and the endless recruiter threads on LinkedIn — and that pattern points one direction: shorter.
The recurring themes, honestly summarized:
- Reading practices vary enormously. Some recruiters read every letter, many skim, some skip them unless a candidate is borderline. No length rescues a letter that never gets opened; brevity protects you with every reader type that does open it.
- Skimmers read the first paragraph and maybe the first line of each subsequent one. Length spent after paragraph two has steeply diminishing returns.
- The complaint recruiters actually voice is nearly always "too long" or "just repeats the resume" — essentially never "too short." When one side of an error is frequently punished and the other side almost never is, err toward the unpunished side.
That's the honest evidentiary basis: consistent practitioner testimony, not laboratory data. It supports 250–350 words as a confident default, not a law of nature.
The cut-it-in-half editing method, demonstrated
The fastest route to a tight letter is to write loose and cut hard. Draft at whatever length the material wants — 500, 600 words — then halve it in three passes. Watch it work on a real (invented) example.
The original paragraph (98 words):
"I am writing to apply for the Operations Analyst position that I saw advertised on your careers page last week. Throughout the course of my career, I have always been passionate about using data to solve operational problems, and I believe that this passion, combined with my strong analytical skills, would make me a great fit for this role. In my current position at Delvane Logistics, I have been responsible for a number of projects involving process improvement, including one project where I was able to successfully reduce our warehouse picking error rate by a significant margin."
Pass 1 — cut throat-clearing (announcements, hedges, and phrases that delay the point): "I am writing to apply for," "Throughout the course of my career," "I believe that," "I have been responsible for a number of projects including one project where I was able to successfully." Every one of these is scaffolding left up after construction.
Pass 2 — cut duplication: "passionate about using data" and "strong analytical skills" are the same claim twice, and both are adjectives doing a number's job.
Pass 3 — replace vague with specific: "a significant margin" becomes the actual figure; "process improvement" becomes the actual process.
The result (36 words):
"At Delvane Logistics, I rebuilt our warehouse picking workflow and cut the error rate from 4.1% to 1.3% in five months. That's the kind of problem the Operations Analyst role seems built around — which is why I'm applying."
Sixty-two percent shorter, and every remaining word is either evidence or connection. Run these three passes over a full draft and a 550-word letter reliably lands near 300 without losing a single fact — because the cuts were never facts.
What to cut first: throat-clearing, repetition, resume echoes
When your letter is over budget, cut in this priority order:
- Throat-clearing. "I am writing to express my interest," "As you can see from my resume," "I would like to take this opportunity to." These phrases exist to warm up the writer, not inform the reader. Cutting them costs nothing, ever.
- Adjective self-praise. "Highly motivated," "detail-oriented," "results-driven" — unverifiable claims that evidence elsewhere in the letter should be making instead. If the evidence exists, the adjectives are redundant; if it doesn't, they're unsupported.
- Resume echoes. Any sentence that restates a resume bullet in prose form. The recruiter has the resume. The letter's paragraphs must add context, motivation, or texture the bullets can't hold — sentences that merely re-deliver bullets are the largest single source of letter bloat.
- The second story. If your proof paragraph tells two stories, keep the one more relevant to this posting and bank the other for the interview. Two stories at half-depth persuade less than one at full depth.
- Closing hedges. "If you feel my qualifications are a match, please don't hesitate..." — the entire conditional apparatus can compress to a confident two-sentence close. Our guide to ending a cover letter shows the compact versions.
What you should not cut to save space: the specific number in your proof story, the researched detail in your fit paragraph, or the recipient's name. Those are the letter.
When longer is justified: academic, federal, and executive letters
Three genuine exceptions to the 250–350 default:
- Academic cover letters are a different genre. Letters for faculty and research positions conventionally run one to two full pages, covering research agenda, teaching philosophy, and fit with the department. Applying business-letter brevity to an academic search reads as underprepared. Follow the norms of your field and the posting's instructions.
- US federal applications and some other government processes may ask you to address specific qualification criteria point by point. Where instructions specify content, instructions beat brevity — cover every required element, as compactly as each allows.
- Executive letters have more latitude, into the 400–500 word range, because the letter often carries a capsule leadership narrative and a point of view on the organization's strategy. The discipline still applies; the budget is just larger. A rambling executive letter damages a candidacy at least as much as a rambling analyst letter.
Outside these, "my situation is complicated" rarely justifies length. Career changes and employment gaps need one calm sentence of context, not an extra paragraph — the same principle that governs resume length, where complexity is handled by selection, not expansion.
Word counts for form-field "why us?" boxes
Increasingly, applications skip letter uploads for a text box: "Why do you want to work here?" or "Anything else we should know?" These have their own budgets:
- If the box states a limit, treat about 80% of it as your target. Maxing out a 200-word limit with 200 words reads differently than landing at 160 with room to breathe.
- If it's unlimited, write 80–150 words: your hook and a compressed proof story, merged into one paragraph. No greeting, no sign-off — form fields strip the letter frame, so the conventions go with it.
- One dense paragraph beats three thin ones in a form field. The rendering rarely preserves formatting gracefully, and the reader is in speed mode.
The skill transfers directly: a form-field answer is just a cover letter after the cut-it-in-half method has been applied twice.
Frequently asked questions
Is a 150-word cover letter too short?
Not automatically — a 150-word letter with a named referrer, one metric-backed accomplishment, and a specific reason for the company beats a 400-word letter with none of those. But check what's missing: at 150 words there's usually no proof story, and the proof story is the letter's engine. If all four structural jobs are done in 150 words, send it with confidence.
Does anyone actually count the words?
No recruiter is running your letter through a word counter. Length operates visually: the reader sees a dense full page or a clean two-thirds page and forms an expectation before reading. The word targets in this guide are just reliable proxies for producing the right visual and the right reading time.
Should a cover letter ever be two pages?
For standard industry applications, no — a second page nearly guarantees the second half goes unread. The exceptions are genre-based: academic letters, federal applications with mandated criteria, and occasionally executive searches where the letter functions as a strategy memo. If you're not in one of those situations, two pages means the editing isn't finished.
Is it fine if my cover letter is only three paragraphs?
Yes. The four-paragraph structure separates jobs for clarity, but merging the fit paragraph into the proof or the close works fine at shorter lengths. Structure serves the argument — what matters is that hook, proof, fit, and close all happen, not that each gets its own visual block.
Trim the letter, then weigh the resume
The same editing discipline that gets a letter to 300 words is what gets a resume to the right length for your career stage. Run yours through Workplacea's free resume checker — it flags the padding, the duplicate claims, and the bullets that echo instead of add, so both halves of your application respect the reader's time.
