How Long Should a Cover Letter Be? (Recruiter Word-Count Test)

Cover letter length is one of the few things worth being strict about, because it changes whether the letter gets read at all.

Think about how a recruiter actually reads a stack of cover letters from a single posting: open, scan the first sentence, decide within seconds whether to keep reading or skip to the CV. There’s an inflection point between I’ll read this and I’ll skim it, and it sits at roughly 250 words.

Below 250 words, the whole letter tends to get read. Above 350, it tends to get skimmed. Between 250 and 350 is mixed, depending on how the first sentence lands.

So if you’re wondering how long your cover letter should be, and you’re getting “one page” advice from Google, here’s a more useful answer: around 250 words, three paragraphs. Anything longer is fighting the attention economy, and the attention economy always wins. (For the bigger structural picture — when a letter is even worth writing, what to send instead — start with the cover letter pillar.)

Why the number matters

Recruiters don’t read cover letters the way candidates assume they do. They’re not looking for a well-structured argument. They’re looking for signal, fast. In a typical application review, a recruiter is checking three things:

1. Can you write? (The first sentence usually tells them.)
2. Do you have a reason for applying? (One specific sentence is enough.)
3. Are you a plausible fit? (The CV confirms; the letter just signals intent.)

All three can be answered in 200-250 words. Anything beyond that is you writing for yourself, not for the reader. A 600-word cover letter rarely reads as “thorough candidate.” It reads as “this person doesn’t know their reader.”

The three-paragraph structure that hits the length

The reason 250 words works is that it maps cleanly onto three paragraphs of 80-90 words each. Each paragraph does one job. When you know the job of each paragraph, you don’t pad.

Paragraph 1: the hook (80 words)

Specific first sentence. No “I am writing to express my interest.” No “I am excited to apply for the position of.” Just a concrete sentence that tells the reader why you, why this role, why now.

Examples that work:

“Your job ad mentions rebuilding the pricing model after the last person left, and I just did the same thing at [prior company] for a product with twice the catalog complexity.”

“I’ve been following [Company]‘s move into [market] for a year because I’m on the customer side of that market and I’ve been waiting for someone to solve the problem you’re solving.”

The hook should make the reader want to read paragraph 2. If it doesn’t, the rest of the letter doesn’t matter. The 5 opening line patterns that work covers each variant in detail with before/after examples.

Paragraph 2: the case (100 words)

Two or three specific reasons you’d be good at this role. Not your full CV, just the two or three things most relevant to this specific posting. Use numbers wherever you can. “Built X that increased Y by Z” beats “led initiatives to drive improvements.”

Don’t try to cover everything. Pick the two things that are most relevant and explain them in enough detail that the reader can picture you doing similar work here. A common mistake: candidates list 6 qualifications at shallow depth. Better: 2 at real depth.

Paragraph 3: the close (60 words)

Short, direct, warm. Restate interest in one sentence. Signal availability if it matters. End with something human, not corporate.

“Happy to elaborate on any of the above in a call. I’m UK-based, available for a conversation any time next week.”

Don’t finish with “I look forward to hearing from you at your earliest convenience.” That’s a phrase people stopped writing in 2015 and only AI now produces.

What AI gets wrong about length

If you paste the job description into ChatGPT and ask for a cover letter, you’ll almost certainly get 400-500 words. The default AI cover letter is long. It’s also structurally perfect, grammatically clean, and instantly recognizable as AI output, partly because of the length.

When you edit an AI draft, expect roughly half the edits to be cuts. AI expands every sentence, hedges every point, and adds corporate connective tissue (“additionally,” “furthermore,” “moreover”) that pads the word count without adding information.

The fix is a specific prompt constraint. A prompt that keeps an AI cover letter draft to the right length includes:

“Maximum 250 words. Three paragraphs. First sentence must be specific, not generic. No ‘I am writing to express interest.’ No ‘I look forward to hearing from you.’”

That produces a draft closer to the right length. Then cut another 20% in the edit, because AI still overshoots.

When longer is acceptable

There are specific cases where a longer cover letter (up to 400 words, occasionally more) is appropriate:

Senior executive roles

If you’re applying for a C-level or VP role, search committees and HR directors expect a full one-page letter. Shorter can read as underprepared. The exception: if the role is at a technology company with a casual culture, shorter still works.

Career changers

If you’re switching industries or functions, you need a paragraph to explain the pivot. That adds 50-80 words. So a career-change cover letter might run 300-350 words rather than 250. Still not a full page, just a bit more room for the bridge — see career change cover letter for the specific structure, and what UK recruiters look for in career-changers for the wider framing.

Academic and legal roles

Different norms. Academic cover letters are often 400-600 words with a research statement embedded. Legal cover letters tend to be formal and slightly longer. If you’re in these fields, ignore the 250-word default and follow the field’s conventions.

When the posting explicitly asks

If the ad says “please include a detailed explanation of your interest” or similar, that’s a license to go longer. They’ve told you they’ll read it. Use up to 400 words, not more.

The word-count check

Before you send, do this. Paste your letter into a word counter (any online tool, or the one built into Google Docs or Word). Read the number. If it’s over 350, cut. Every time.

The cuts are usually:

• Entire sentences that restate something the CV already says
• Transition phrases like “additionally,” “moreover,” “furthermore”
• Hedges like “I believe,” “I feel,” “it is my opinion”
• Adjectives that don’t add information (“various,” “numerous,” “innovative”)
• The closing sentence, which is often 30 words longer than it needs to be

A 400-word draft cut to 250 is almost always a better letter. In UK hiring, the strongest candidates tend to send the shortest letters. Not because brevity is a magic formula, but because brevity forces clarity, and clarity is what recruiters actually respond to.

The minimum floor

The other direction matters too. Below 100 words, a letter stops reading as a cover letter and starts reading as a dashed-off email. A 60-word note that says essentially “I saw the ad, I’m interested, CV attached” is technically a cover letter. Practically, it signals low effort.

The minimum that reads as considered: around 120-150 words. Three short paragraphs, each doing their job. It’s closer to the floor than the ideal, but it’s not insulting. (If your letter is going via an InMail or referral rather than a portal, the parallel rules for the LinkedIn channel run shorter still — different medium, different floor.)

What to take from this

Cover letter length is not a format rule. It’s a reader-attention rule. Recruiters spend 20 seconds or less on cover letters, and your letter has to earn more time by being short enough to read in that window and specific enough to justify the read.

The safe default: 250 words, three paragraphs, first sentence specific, last sentence human. You can adjust up or down for your situation, but if you’re within 50 words of that target, you’re in the right zone. Most candidates fail by going long, not by going short. Be the one who goes the other way.
