How long should a cover letter be?

A cover letter should be 250–400 words — approximately three to four short paragraphs that fit on a single page. Most hiring managers spend fewer than 30 seconds reading a cover letter, so concise and specific beats long and general every time. Never exceed one page.

Is a 500-word cover letter too long?

Yes, 500 words is generally too long for a cover letter. At 500 words, you risk losing the reader's attention and pushing onto a second page, both of which work against you. If your cover letter reaches 500 words, look for duplicate ideas, generic sentences, and unnecessary context that can be cut without reducing the strength of your argument.

Can a cover letter be too short?

Yes. A cover letter under 150 words signals low effort and doesn't give you enough space to make a compelling case. Aim for at least 250 words so you can explain your fit for the role, highlight one or two specific achievements, and express genuine interest in the company — all of which a very short cover letter can't adequately do.

Cover Letter Length Guide — How Many Words Is Too Many?

The Sweet Spot: 250–400 Words

Career advisors, recruiters, and HR professionals are remarkably consistent on this point: the ideal cover letter is 250 to 400 words. That's roughly three to four focused paragraphs, all fitting comfortably on a single page. This length is long enough to make a meaningful case for your candidacy and short enough to respect the reader's time.

Word Count	Pages	Assessment
Under 150 words	<1	Too short — signals low effort; insufficient to build a case
150–249 words	~0.5	Borderline — acceptable for very junior roles with narrow scope
250–400 words	1	Ideal — complete, focused, respectful of the reader's time
401–500 words	1	Acceptable — review for cuts; approaching the upper limit
Over 500 words	1–2	Too long — cut aggressively; risks losing the reader
Over 700 words	2+	Far too long — rarely read in full; strongly revise

The one-page rule: A cover letter should never exceed one page. If yours does, it's a clear signal to cut — not to reduce font size or margins. Shrinking formatting to squeeze a long letter onto one page creates a wall of text that's even harder to read than a two-page letter.

How Hiring Managers Actually Read Cover Letters

Understanding how your cover letter is actually consumed fundamentally changes how you should write it. Multiple eye-tracking studies and recruiter surveys point to the same pattern: most hiring managers spend fewer than 30 seconds on a cover letter during the initial screening pass. Some spend less than 10 seconds before deciding whether to read further or move on.

This doesn't mean cover letters don't matter — it means the structure and density of your cover letter matters enormously. A well-written 300-word letter with a compelling first sentence, clear paragraphs, and specific achievements will be read fully. A 550-word letter with a meandering opening and repetitive content will be skimmed for 20 seconds and discarded.

What recruiters scan for in those 30 seconds

Experienced recruiters have well-trained pattern-recognition. During a fast scan, they look for:

The first sentence — does it immediately signal relevance and confidence?
The role and company name — is this letter clearly tailored, or generic?
Any bolded phrases or standout numbers that catch the eye
The closing line — does it end with a clear, confident call to action?
Overall length and density — does it look readable at a glance?

The implication for length: a shorter letter that passes the 30-second scan test outperforms a longer, more comprehensive letter that fails it. Getting read in full is more valuable than fitting in every piece of relevant experience.

A Four-Paragraph Structure That Works

The most reliable structure for a 250–400 word cover letter follows four short paragraphs, each with a single, clear purpose. This structure works for most industries and roles:

Paragraph 1: The hook (50–75 words)

Open with a specific, confident statement about why you want this role at this company and why you're a strong fit. Name the position. Avoid generic openers like "I am writing to express my interest in..." — they waste your most valuable real estate. Instead, lead with your most compelling qualification or a specific reason you're excited about this company's work.

Paragraph 2: Your strongest achievement (75–100 words)

Choose one achievement — the most relevant to this role — and describe it specifically. Include what you did, the scale or context, and the measurable result. "Increased customer retention by 18% over six months by redesigning the onboarding email sequence" is far stronger than "improved customer outcomes." One specific, quantified achievement is more convincing than three vague claims.

Paragraph 3: Why this company specifically (50–75 words)

Show that you've done your research. Reference something specific about the company — a product, a mission statement, a recent initiative, or a piece of work you admire — and connect it to your own experience or values. This paragraph is where you differentiate a tailored letter from a generic one. It signals investment in the opportunity.

Paragraph 4: The close (30–50 words)

End with a clear, confident call to action. Express that you'd welcome the opportunity to discuss your candidacy further, and thank the reader for their time. Keep it brief — this is not the place for a final summary of your qualifications.

What to Cut When Your Letter Is Too Long

If your cover letter exceeds 400 words, it almost certainly contains content that can be cut without weakening your application. Here are the most common sources of excess length:

Generic openers: "I am pleased to submit my application for the position of..." — delete the whole first sentence and start with your hook
Repeating your resume: Your cover letter should not summarize your resume; it should interpret and contextualize it
Multiple achievements instead of one great one: Three vague achievements fill space without persuading; one specific, quantified achievement does the work of all three
Explaining your career change at length: One clear sentence is sufficient; more reads as defensive
Clichés and filler phrases: "I am a team player," "I think outside the box," "I am passionate about..." — these add words without adding information
Restating what the job posting says: Describing the role back to the recruiter is wasted space; use that paragraph to show what you bring to the role

How to Check Your Word Count

Before submitting any cover letter, paste the full text into a word counter or character counter to verify your length. This takes 10 seconds and immediately tells you whether you need to expand or cut. Many word processors display word count in their status bar, but a dedicated tool gives you character count, sentence count, and reading time as well — useful data when you're calibrating for length and density.

Aim to submit a cover letter between 250 and 400 words, formatted in 10–12pt font with standard 1-inch margins, filling approximately 60–80% of a single page. This presentation signals professionalism and confidence — your writing is complete, not padded, and not rushed.
