How Long Should a Cover Letter Be?

The word-and-page rule: 250-400 words, one page

The target is 250 to 400 words. That range is long enough to introduce yourself, connect your experience to the specific role, and offer one or two concrete proof points, but short enough that a recruiter scanning a stack of applications will actually read it. Land closer to 250 when your relevant experience is easy to state, and closer to 400 when the role genuinely warrants more context — a senior position, a career pivot you need to explain, or a posting with several distinct requirements you can each speak to. Going much past 400 is almost always a sign you are repeating your resume or over-explaining.

On the page, 250 to 400 words of body text usually fills somewhere between half a page and three-quarters of a page once you add the standard furniture: a header with your name and contact details, the date, the hiring manager's name or company line, a greeting, and a sign-off with your name. With normal formatting that leaves comfortable white space and lands you safely under the one-page ceiling. The one-page limit is not a stylistic preference — it is a signal. A cover letter that runs to a second page reads as someone who could not prioritize, which is the opposite of the impression you want.

For formatting that supports the length without crowding the page: use a clean, professional font at 10.5 to 12 points, single line spacing with a blank line between paragraphs, and roughly one-inch margins. If your letter is running long, fix it by cutting words, not by shrinking the font below ~10.5pt or squeezing the margins — a wall of tiny text is harder to read and obviously padded, and recruiters notice both.

Why shorter almost always wins

Cover letters are skimmed, not studied. A recruiter or hiring manager moving through dozens of applications gives each one a short first pass, and a long letter does not buy you more attention — it spends the limited attention you have. Every extra paragraph is a paragraph that dilutes your strongest point and increases the odds the reader bails before reaching it. A concise letter respects the reader's time, and that respect itself reads as professionalism.

Brevity also forces clarity. When you have only 250 to 400 words, you cannot afford filler like "I am writing to express my strong interest in the position" or a paragraph-long recap of your entire career — you have to choose the one or two things that actually make you a fit and lead with them. That discipline produces a sharper letter. The candidates who struggle to keep it short are usually the ones who have not decided what their core argument is; the word limit is doing them a favor by forcing the decision.

There is a practical signaling layer too. Hiring teams read the length and structure of a cover letter as a proxy for how you communicate on the job. A tight, well-organized one-page letter suggests someone who can get to the point in an email, a status update, or a stakeholder summary. A rambling two-page letter suggests the opposite — before anyone has evaluated your actual qualifications.

The structure that fits the length

The 250-to-400-word, 3-to-4-paragraph shape is not arbitrary — it maps onto a natural structure where each paragraph does one job. Think of it as an opening hook, one or two body paragraphs of evidence, and a short close. If you write to that structure, you land in the right length almost automatically, because each part has a built-in stopping point.

When even shorter is fine: email and LinkedIn versions

The 250-to-400-word target is for a formal cover letter — the kind you attach as a PDF or paste into a dedicated cover-letter field on an application. When you are instead writing in the body of an email or sending a LinkedIn message to a recruiter or hiring manager, go shorter: roughly 150 words, two to three tight paragraphs, and short sentences. These contexts are read on phones, scanned in seconds, and compete with a crowded inbox, so concision matters even more than in a formal letter.

The structure compresses but does not disappear: a one-line opener that says who you are and why you are reaching out, one short paragraph connecting your background to the role or to why you admire the company, and a one-line close with a clear next step. You can always offer to share a full cover letter or resume as an attachment or link. For a quick recruiter outreach message, even 75 to 120 words can be appropriate — the goal is to start a conversation, not to make the entire case in one message.

Can a cover letter be two pages? (No.)

No. For the overwhelming majority of applications, a cover letter should be one page, full stop. A two-page cover letter signals that you could not edit yourself or distinguish what matters from what does not, and it asks for more of a busy reader's time than the format earns. If your draft is running to two pages, that is a cutting problem, not a length allowance — the fix is to remove the resume restatement, trim the throat-clearing openers and closers, and keep only your strongest one or two proof points.

There are narrow exceptions, and they are genuinely narrow: some academic, federal/government, and certain senior executive applications use longer formats (an academic cover letter or a federal resume narrative can run longer by design and by explicit instruction). Those are governed by the application's stated requirements, not by general cover-letter norms — and even then, you follow the instructions rather than padding for the sake of length. For a standard private-sector job, treat one page as a hard limit, not a target to push against.

Length mistakes that pad a cover letter

Most over-long cover letters are not long because the candidate had too much to say — they are long because of a handful of predictable padding habits. The most common is restating the resume: walking through your job history paragraph by paragraph when the reader already has that document. The cover letter should interpret and prioritize, not duplicate. Cut any sentence that simply re-narrates a resume bullet.

Other reliable culprits: generic opening lines ("I am writing to express my interest in..."), long wind-up before you get to the point, listing soft-skill adjectives ("hardworking, detail-oriented, passionate") instead of showing them with one concrete example, and over-explaining your motivation or backstory. A useful editing pass is to read each sentence and ask, "does this give the reader a new, role-relevant reason to interview me?" If not, it goes. That single test will usually pull a bloated 600-word draft back into the 250-to-400-word sweet spot.

The last mistake is fixing length cosmetically instead of editorially — shrinking the font, narrowing the margins, or deleting the spacing between paragraphs to cram more words onto the page. That makes the letter harder to read and obviously padded, and it defeats the purpose of the limit. If the words do not fit comfortably on one page at a readable font size, the answer is fewer words, not smaller ones.

So, how long should a cover letter be?

Aim for 250 to 400 words, 3 to 4 short paragraphs, and one page — closer to half a page of body text once you add your header, greeting, and sign-off, and never spilling onto a second page. Build it as an opening hook, one or two body paragraphs of concrete proof, and a brief close, and the right length will largely take care of itself. If you are writing in an email or a LinkedIn message instead of attaching a formal letter, cut to roughly 150 words. When you are unsure, cut: a shorter, sharper letter beats a longer, fuller one almost every time.

If hitting that length while staying tailored to each role is the hard part, that is exactly the work a tool can take off your plate. Resumly generates a cover letter matched to the specific job — naming the role, pulling the relevant requirements, and keeping it to a tight one-page draft you can edit — so you get a correctly-sized, role-specific letter without staring at a blank page. You can try it free with no credit card, then trim to taste using the one-page rule above.
