Is your cover letter the right length?

Hit the sweet spot — 250–400 words.

A cover letter that's too long gets skimmed and forgotten; too short and it looks like you didn't try. The sweet spot is 250–400 words in three or four tight paragraphs — long enough to make a specific case, short enough to respect a recruiter's six-second scan. The Length Checker tells you instantly where you stand: word count, character count, sentence count, reading time and an honest verdict.

It works on any text, not just cover letters — a LinkedIn summary, an outreach email, a personal statement. When you're ready to write the letter itself, CoverCraft drafts a grounded one from your real resume; run it back through the checker to trim it to length.

Why recruiters reject cover letters on length alone

A cover letter shorter than 100 words reads incomplete—the recruiter may dismiss it as low effort. One longer than 500 words competes for attention with other candidates' letters and competing tasks, and most recruiters will skim rather than read, which means your core argument gets missed. The sweet spot of 250 to 400 words is long enough to make a specific, grounded case but short enough that a recruiter can read it in one to two minutes without skim-skipping.

The economics are straightforward. A recruiter spends fifty seconds scanning the rest of your application (resume, LinkedIn profile). They will spend sixty to ninety seconds on a cover letter if it signals relevance—that is, if the opening paragraph shows you understand the specific role, not a generic template. A letter over 500 words demands a two-to-three-minute commitment when the recruiter has twenty more applications to review. The only way to justify that time is if the letter contains information not on your resume—a specific story, a unique qualification, or proof that you have done this role before. Most do not.

Acceptance-rate data from hiring teams that track cover letter length shows a sharp drop in interview callbacks for letters over 450 words. The correlation is not causal—long letters often lack focus, which is why they are long—but the pattern is consistent. Conversely, a tight 280-word letter with a specific opening, one concrete example, and a clear close yields higher callback rates than a 150-word one that feels rushed. Length signals effort; over-length signals either unclear thinking (the candidate could not distil the message) or disrespect for the recruiter's time (the candidate thinks their story is worth an extra read-through, regardless of other workload).

Fitting your story into 250 to 400 words

The three-paragraph structure holds all of this: an opening that names the role and why you are interested (specific, not generic), one body paragraph with a single concrete story or accomplishment that maps to the role, and a close with a call to action. Each paragraph should be three to five sentences. This structure works because it mirrors how recruiters actually read: opening (is this person serious about us?), middle (does this person have relevant skills or context?), and close (what do they want next?). A fourth paragraph is possible but eats into your words and usually rehashes resume content.

The mistake is trying to summarize your entire resume in a letter. That is what the resume does. A cover letter is the one place to provide context the resume cannot: why you are switching industries, why you care about this company specifically, or a story that shows your working style rather than just listing roles. "I have ten years as a backend engineer" is resume content. "During a launch crisis, I shipped a critical caching layer in 36 hours, and this experience showed me I thrive in high-velocity teams." That is a letter. It provides evidence and context that makes the resume actionable.

Word budgets break down like this: opening (40-60 words), body story (120-180 words), close (30-50 words). This leaves room for variation and a sentence or two of connective tissue. If you are at 380 words, you have room for a very brief second body paragraph, but only if it is distinct from the first—not a rephrasing of the same point. Most strong letters stay between 250 and 350 words; the extra space to 400 is for candidates with complex backgrounds (career change, relocation, re-entry after a gap) that genuinely need explanation.

How format affects perception of length

A letter in three paragraphs, each four sentences or fewer, appears shorter and more readable than the same letter in five cramped paragraphs. Margin, line spacing, and font size all affect perceived length independent of word count. A 350-word letter in single spacing with 0.5-inch margins looks dense and reads as longer. The same letter in 1.15 spacing with 0.75-inch margins breathes and does not feel padded. Recruiters often skim short sections, so the visual signal (is this letter approachable?) matters.

Most online cover letter templates add 50 to 100 words of boilerplate—"Dear Hiring Manager," a formal close, and generic pleasantries. These are expected but they consume word budget. If you have 400 words total, fifty of them are salutation and closing, leaving 350 for your actual content. Some templates auto-bloat: they have large headers, spacing, or graphics that make a 250-word letter look like 350 words. If you are using a template, count actual words, not perceived length.

Length also depends on context. An email cover letter (pasted directly into an email, no attachment) should be tighter—200 to 280 words is standard—because email feels more casual and oversized emails risk getting cut off on mobile. An attached cover letter can stretch to 400 words because the recruiter chose to open a document. The format signals how much time they are allocating. Respond to that signal rather than using a one-size-fits-all length.
