How Long Should a Cover Letter Be? (A Rule You Can Apply)

A mid-career professional deciding how long a cover letter should be, the reframe that length is a function of evidence rather than a word count, why the length question is really an evidence question, the one-page four-paragraph rule, how long to write in five common situations, what to cut when it runs long, what to add when it runs short, a worked example, and the four mistakes

How long should a cover letter be is the question people ask right before they either pad a page with adjectives or delete the letter entirely, and both answers are wrong. Length is not a formatting preference. It is a direct function of how much evidence you have to offer, and most letters are too long because they are carrying sentences that prove nothing.

Here is the reframe: A cover letter is as long as it takes to earn the next sentence. The reader is not measuring your word count - they are deciding, line by line, whether to keep reading. One page and four paragraphs is the default because that is usually where the evidence runs out, not because a rule says so.

What follows is the whole method: why the length question is really an evidence question, the rule that settles it, how long to write in five common situations, what to cut when it runs long, what to add when it runs short, a worked example, and the four mistakes.

Why the length question is really an evidence question

People ask about length because they are unsure what belongs in the letter. Once you know what belongs, the length decides itself.

Every extra sentence dilutes the strong ones. A letter with three pieces of evidence and eleven sentences of filler reads as weaker than a letter with three pieces of evidence and four sentences.
Recruiters skim, then decide. The first two lines get read. The rest gets read only if those two lines earned it, which means the opening matters more than the total.
Long letters usually repeat the resume. If a paragraph restates your history, it is not doing a job the resume has not already done.
Short letters usually skip the argument. A three-sentence letter is not disciplined, it is unfinished - it names the role and stops before it says anything.

The structure this is built on is the value-first cover letter formula, and the fill-in-the-blank version is the cover letter value proposition templates.

The rule: one page, four paragraphs, 250 to 400 words

Four paragraphs, each with one job, is the whole letter. Anything longer gets skimmed and anything shorter looks like you did not try.

Paragraph one: the role and the problem. Two sentences. Name the job, then name what the hire is actually for.
Paragraph two: the closest evidence. Three to five sentences. One or two things you have done that map to the work, described as outcomes.
Paragraph three: the gap and the plan. Two sentences. One honest line about what you are missing, one line about how you are closing it.
Paragraph four: the close. Two sentences. A specific, low-friction ask with two times you are free.

How long to write in five common situations

The default is one page. These are the situations where the balance shifts.

Situation	Target length	Why
Career change	350 to 400 words	You must argue the transfer, so paragraph two carries more
No direct experience	250 to 300 words	Less history to summarise; the argument is understanding
Senior or executive	300 to 350 words	Fewer, larger claims; the reader has less patience
Internal transfer	200 to 250 words	The reader knows you; only the argument is new
Warm referral	200 to 250 words	The referral does the work; the letter must not repeat it

What to cut when it runs long

Almost every over-long letter is over-long for one of four reasons.

Cut the interest statement. 'I am writing to express my interest' and every variant of it says nothing the subject line did not.
Cut the company flattery. One sentence about why this company is enough. Two paragraphs about their mission is a research paper, not a letter.
Cut the resume recap. If a sentence lists your roles or dates, the reader already has it. Replace it with the outcome.
Cut every adjective about yourself. Hard-working, passionate, detail-oriented - each one costs you a sentence and proves nothing.

What to add when it runs short

A short letter is usually missing one of three things.

Add the problem. One sentence naming what the role is really for turns a summary into an argument.
Add the outcome. If your evidence describes a duty, add what changed because you did it.
Add the ask. A letter without a specific next step leaves the reader with nothing to do.

A worked example: Marcus cuts 620 words to 310

Marcus had written a 620-word letter he was proud of: an opening about his passion for the company, two paragraphs of his career history, a paragraph on their recent product launch, and a closing about how much he would love the chance. He sent it to nine roles and heard nothing. He rewrote it against the four-paragraph rule. Paragraph one named the role and the problem: their support team was absorbing a new product line and needed someone who could write the internal playbook. Paragraph two gave one piece of evidence - the help-centre rebuild he had led that cut repeat tickets by a third - in three sentences. Paragraph three named the gap: he had not worked on a product launch, and he had already started a short course on release documentation. Paragraph four asked for twenty minutes and gave two windows. The letter was 310 words. He sent it to six roles and got three replies. Nothing in the new letter was unavailable to the old one. The old one had simply buried the only three sentences that mattered under nine that did not.

The four mistakes

Cover letter length goes wrong in four predictable ways, and each one is a step you can add back.

Mistake	What it looks like	The fix
Padding to fill a page	Soft-skill adjectives and mission paragraphs	Cut to the evidence; a short letter beats a padded one
Restating the resume	A paragraph of roles and dates	Replace history with the outcome it produced
Skipping the argument	Three sentences that name the role and stop	Add the problem, the evidence and the ask
One letter for every role	The same page sent to nine postings	Rewrite paragraph one and two for each posting

The cover-letter length checklist

One page, four paragraphs, as many words as the evidence earns.

The letter is one page or less?
It has four paragraphs, each with one job?
Paragraph one names the role AND the problem?
Paragraph two is evidence, not a summary of my history?
Paragraph three names the gap once and the plan?
Paragraph four asks for a specific next step?
I have cut 'I am writing to express my interest'?
I have cut the company flattery to one sentence?
I have cut every soft-skill adjective?
No sentence lists roles or dates the resume already has?
I have read it out loud once?
I rewrote paragraph one and two for THIS posting?

Length by situation

The default is one page. These are the situations where the balance shifts.

Situation	Target length	Why
Career change	350 to 400 words	You must argue the transfer
No direct experience	250 to 300 words	Less history; the argument is understanding
Senior or executive	300 to 350 words	Fewer, larger claims; less patience
Internal transfer	200 to 250 words	The reader knows you
Warm referral	200 to 250 words	The referral does the work

The close

One page, four paragraphs, and as many words as your evidence earns - usually between 250 and 400. If you are writing with no direct experience, the shorter version is how to write a cover letter with no experience, and if you want the structure behind the four paragraphs, the value-first formula is the place to start.

Quick answers

Short answers to the questions this piece gets asked most.

How long should a cover letter be?
One page, four paragraphs, and usually between 250 and 400 words. The number is not the rule - the rule is that the letter is as long as it takes to earn the next sentence, and most letters run long because they carry sentences that prove nothing.

Is a short cover letter better than a long one?
A short letter with evidence beats a long one padded with adjectives, but a three-sentence letter is not disciplined, it is unfinished. Cut the interest statement, the company flattery, the resume recap and every adjective about yourself, then stop.

Should a cover letter be one page or half a page?
One page is the ceiling, not the target. Half a page is right when the reader already knows you - an internal transfer or a warm referral - and a full page is right when you have to argue a transfer from another field.

How many paragraphs should a cover letter have?
Four. One for the role and the problem, one for your closest evidence, one for the gap and the plan, and one for the close. Each paragraph has one job, and a paragraph that repeats another one is the first thing to cut.
