A cover letter should almost always fit on one page , which usually means about 250–400 words or roughly 3–5 short paragraphs.

Quick Scoop

Ideal length (modern standards)

  • Half a page to one full page is the sweet spot.
  • Around 250–400 words is considered ideal by most career experts and hiring platforms.
  • This typically works out to about 12–20 sentences spread across a few focused paragraphs.

The reason is simple: hiring managers often spend 30–60 seconds on a cover letter, so they want something tight, skimmable, and clearly relevant to the role.

Paragraph and structure guide

Most guides now suggest something like:

  1. Opening paragraph – Who you are, the role you’re applying for, and a sharp hook showing why you’re a strong match.
  2. Middle 1–2 paragraphs – 2–3 key achievements that link directly to the job description, ideally with numbers or clear outcomes.
  3. Closing paragraph – Reaffirm interest, show cultural fit in a sentence or two, and add a polite call to action.

That structure keeps it substantial but not overwhelming, and avoids turning the letter into a repeat of your CV.

When can you go shorter or longer?

  • Shorter (around half a page) :
    • Entry-level roles with simple requirements.
    • When the employer clearly doesn’t emphasize cover letters.
    • Highly time-pressured industries where brevity is valued.
  • Standard (most jobs) :
    • One page, 250–400 words, 3–5 paragraphs.
  • Slightly longer (rare) :
    • Academic, research, or certain public-sector roles that explicitly request more detail.
    • Even then, guidelines often say not to go far beyond one page unless the posting says so.

If a job ad sets its own length (e.g., “no more than 300 words” or “three paragraphs”), that always overrides general rules.

What forums and real applicants say

On recent resume/cover-letter forums, people often report that when they cut their cover letters down to about three-quarters of a page , they get better feedback and feel their ideas are more focused. Community advice there tends to favor trimming “fluff,” merging extra-short paragraphs, and sticking close to the 250–400-word zone rather than trying to tell your full career story.

Quick checklist before you send

Ask yourself:

  • Does it fit on one page with normal margins and 10–12 pt font?
  • Is it around 250–400 words, not a wall of text, and easy to skim?
  • Have I focused on 2–3 strong, relevant examples instead of everything I’ve ever done?
  • Have I followed any specific instructions in the job posting (word limit, paragraph count, or format)?

If you’d like, I can help you turn your existing cover letter into a tight, one-page version in that ideal range.
