What is a Cover Letter? (Definition, Examples and Format)

Updated 2026-04-24

A cover letter is a one-page letter you send with your CV when you apply for a job. It introduces you to the hiring manager, explains why you're a good fit for that specific role, and points at the parts of your CV that matter most. The CV says what you've done. The cover letter says what you can do here.

Most applications still ask for one. Even where it's "optional", a tailored cover letter is the cheapest way to stand out from candidates who copy-paste the same CV everywhere.

What is a cover letter for?

Three jobs:

  1. Translate your CV for this role. A CV is a list of facts. The cover letter picks the two or three facts that match this job and explains why they matter for it.
  2. Show you've read the job description. Hiring managers can tell within a paragraph whether you've actually read the JD or sent the same letter to fifty companies. Mentioning a specific responsibility, tool, or value from the posting is the simplest signal.
  3. Sound like a person. CVs are formatted to be skimmed. Cover letters are the only chance to write in your own voice — to give a hiring manager a feel for what working with you would be like.

Cover letter format (UK 2026)

A cover letter has six parts:

  • Your contact details at the top (name, email, phone, optionally LinkedIn) — usually right-aligned or as a header.
  • Date below your details.
  • The hiring manager's name if you can find it. "Dear [First name] [Last name]" or "Dear Hiring Manager" if you can't.
  • Opening paragraph — what role you're applying for, where you saw it, and one sharp sentence on why you're a strong fit.
  • Two or three middle paragraphs — concrete examples from your background that match what the JD asks for. One paragraph per major requirement.
  • Closing paragraph — restate your interest, mention your CV, and propose a next step (a call, an interview).

Total length: 250–400 words. One page. Anything longer and the hiring manager won't read it.

Cover letter examples

Graduate applying for a first marketing role

Dear Sarah,

I'm applying for the Junior Brand Marketer role advertised on LinkedIn. The job description mentions you're looking for someone who can run social-first campaigns end-to-end — that's exactly what I did during my placement at Yellow Box, where I planned and shipped three TikTok activations that brought 14% week-on-week growth in followers.

I'm at the start of my career, but I've already learned how to brief designers, write briefs, and read GA4 reports without bluffing. ...

Career-changer moving from teaching into UX research

Dear Hiring Team,

Five years in the classroom taught me how to ask the right questions to people who don't know what they're trying to tell me — which is most of qualitative research. I'm applying for the UX Researcher role at Ardent because your team works with public-sector clients, and that's where I want to spend my next chapter.

Since deciding to switch in early 2025, I've completed the Nielsen Norman Group UX certification and run six unmoderated studies for a side project ...

Senior leader applying for a Director role

Dear Hiring Committee,

I'm applying for the Director of Engineering role at Riverbank Foods. Two parts of the brief stood out: scaling the platform team from twelve to twenty-five over the next year, and rebuilding the on-call rotation so engineers stop dreading nights. I've done both at companies similar to yours.

At my current role I led a team through exactly that transition ...

Cover letter vs CV — what's the difference?

A CV is a structured, scannable document. Sections are predictable: profile, experience, education, skills. A recruiter spends roughly six seconds on a first pass. The CV has to win those six seconds.

A cover letter is prose. It reads top-to-bottom. Its job is to argue why this CV is right for this job. The CV proves capability; the cover letter proves fit.

You need both. A great CV with no cover letter looks generic. A great cover letter with a weak CV doesn't get past the first round.

Common cover letter mistakes

  • Restating the CV. If a paragraph could be cut and pasted from your CV, cut it.
  • Writing about what you want. "I'm passionate about growth" doesn't help anyone. What did you grow, by how much, in what time?
  • Sounding like ChatGPT. Generic AI-written cover letters all use the same hedging phrases ("I'm excited to apply", "demonstrates my passion for"). Hiring managers spot them now.
  • Forgetting to tailor. If you could send the same letter to a different company, you haven't tailored it.
  • Going over one page. Nobody finishes a two-page cover letter.
