The Definitive Guide on How Long a Cover Letter Should Be

You’ve done it. You’ve found the perfect job advert on Jobberman, LinkedIn, or MyJobMag. You've polished your CV until it shines. Now, you face the final boss: the cover letter.

You start writing. You talk about your degree from UNILAG. You detail your SIWES. You describe your NYSC PPA. You list your three previous roles, your skills, your passions. You look up, and you’re on page two.

A panic sets in. “Is this too long? Or does it make me look serious? In Nigeria, don't they like thoroughness? Maybe I should add more?”

Stop.

Let me give you the single most important piece of advice in this entire 4000-word guide. The definitive, non-negotiable, 99.9%-of-the-time answer to “How long should a cover letter be?” is:

ONE PAGE. ALWAYS.

That's it. This article could end right here. But you have questions. “Why only one page?” “What if I'm a senior executive?” “How do I fit 10 years of experience into one page?” “What about an email?”

This is the ultimate, in-depth guide to cover letter length, written specifically for the Nigerian and African job market. We will dissect the “why” and, most importantly, show you the how.

The “One-Page Rule”

Why It’s Your New Religion

In the modern job market, your cover letter is not a biography. It is a 6-second advert.

A 2018 study by the careers site TheLadders found that the average recruiter spends 7.4 seconds scanning a resume. And the cover letter? It gets even less. It's the “pre-screening” document. If it looks long, it gets skipped.

Why “The One-Page Rule” is Non-Negotiable

1. It Respects the Recruiter's Time: A recruiter in Lagos might have 300+ applications for one role. They are overworked and drowning in documents. Handing them a two-page “epistle” is like asking them to read a novel in a traffic jam. It's disrespectful. A one-page letter says, “I am a professional. I value your time. I can get to the point.”
2. It Proves You Can Summarize: The #1 skill in any job—from banking to tech to marketing—is the ability to identify what's important and communicate it clearly. Your cover letter is your first test. If you can't summarize your own career on one page, why would they trust you to summarize a client report, a project update, or a financial statement?
3. It Forces You to Be Strategic: A two-page letter is lazy. It's a “data dump” where you just list everything you've ever done and hope the recruiter finds something good. A one-page letter is strategic. It forces you to do the hard work of selecting your top 3-4 most relevant achievements that match the job description.
4. It's the Modern Business Standard: Gone are the days of long, flowery, “I wish to humbly apply…” letters. The modern business world runs on concise emails, “TL;DR” summaries, and one-page memos. Your application must reflect this.

The Nigerian Context: “Stop Writing Epistles!”

We have a culture of formal, long-winded writing. We're taught in school to “expatiate.” We love titles and flowery salutations. This is a disadvantage in a globalized job market.

A modern recruiter at a FinTech in Yaba or an FMCG in Ikeja is not impressed by your “vocabulary.” They are impressed by impact and clarity.

• Old-School Mistake: “I am writing to express my profound interest in the esteemed position of Junior Associate at your prestigious organization, which I became aware of via an advert…”
• Modern Standard: “I am writing to apply for the Junior Associate role. My two years of experience in data analysis, where I helped increase reporting efficiency by 30%, align perfectly with your requirements.”

Your length is the first signal of whether you are an “old-school” or “modern” candidate.

The Ideal Cover Letter Length by Section

Okay, so “one page.” But what does that mean? A one-page letter in 8pt font with no margins is still a “no.”

“One Page” has a specific format. Let's break it down by word count and paragraph.

The “Sweet Spot” (The TL;DR):

• Page Count: 1
• Word Count: 250 – 400 words
• Paragraph Count: 3 – 4 (plus Salutation & Closing)
• Font Size: 10.5 – 12pt (Arial, Calibri, Inter, Garamond, Times New Roman)
• Margins: 1 inch (2.54cm) on all sides.

Let's dissect the letter.

1. The Header (Your Contact Info)

• Length: 4-5 lines.
• Content: Your Full Name, City & State (e.g., “Lekki, Lagos”), Phone Number, Professional Email, LinkedIn URL.
• Tip for Conciseness: Don't write “Email:” or “Phone:”. Just put the info. And please, no LGA, State of Origin, or marital status. It's irrelevant and unprofessional.

2. The Salutation (The Greeting)

• Length: 1 line.
• Content: Dear Mr. Adebayo, or Dear Hiring Manager,
• Tip for Conciseness: Stop using Dear Sir/Ma. It's lazy and impersonal. Spend 5 minutes on LinkedIn to find a name. If you can't, Dear [Department] Hiring Team, is far more professional.

3. The Opening Paragraph (The 6-Second Hook)

• Length: 3-4 lines (approx. 40-60 words).
• Purpose: Grab their attention. State the role you're applying for and give your single most compelling reason for them to keep reading (your “hook”).
• AVOID (Too Long): “My name is Tunde, and I am a recent graduate of the University of Lagos with a 2:1 in Business Administration. I am writing to apply for the Graduate Trainee role I saw on Jobberman. I have always been interested in your company…” (Yawn. You've wasted 4 lines saying nothing).
• GOOD (Concise & Powerful): “I am writing to apply for the Graduate Trainee role. As a recent First-Class graduate who grew my university club's Instagram followers by 300% in one year, I am excited to bring my proven digital marketing and leadership skills to your team.”

4. The Body Paragraph(s) (The “Proof”)

• Length: 1-2 paragraphs, 4-6 lines each (approx. 100-200 words total).
• Purpose: This is the core of your letter. This is where you provide proof (not just claims) that you match the job description.
• Tip for Conciseness: This is where you must be ruthless. DO NOT list your job duties. (That's what your CV is for). DO highlight 2-3 key achievements with numbers.
• AVOID (Too Long & Fluffy): “In my last role as a Sales Executive, I was responsible for calling clients, managing the sales database, writing reports, and attending team meetings. I worked hard to meet my targets and was a good team player. I also had to handle customer complaints and…” (This is a list of duties, not achievements).
• GOOD (Concise & Impactful): “At my last sales role, I was tasked with breaking into the Port Harcourt market. I developed and executed a new outreach strategy that grew our client base by 40% in six months. This involved securing 15 new high-value accounts and increasing regional revenue by N25 million. This experience directly aligns with your need for a ‘proven business developer.'”
• Using Bullet Points: For conciseness, you can use 2-3 bullet points in your body to break up text and highlight key achievements.

5. The Closing Paragraph (The Call to Action)

• Length: 2-3 lines (approx. 30-50 words).
• Purpose: Reiterate your enthusiasm and give a clear, confident call to action (CTA).
• AVOID (Too Long & “Beggy”): “I am humbly begging you to please consider my application as I am a poor graduate and I desperately need this job. I know I can be a good fit if you just give me a chance. I am pleading for a favorable response. I will be waiting for your call.” (This “Naija-style” begging is unprofessional and screams desperation).
• GOOD (Concise & Confident): “I am confident my skills in logistics and my passion for your company's mission can add significant value to your team. I have attached my CV and look forward to discussing my qualifications in an interview.”

6. The Sign-Off

• Length: 2 lines.
• Content: Yours sincerely, (if you used a name) or Yours faithfully, (if you used “Dear Hiring Manager”). Followed by your typed full name.

Cover Letter Length by Experience (The “What If…”)

“But I'm a fresh graduate!” “But I'm a Senior Manager!” The one-page rule applies to 99% of you. The content is what changes.

Scenario 1: How Long for a Fresh Graduate (NYSC / No Experience)?

• Length: One Page. (Approx. 250-300 words).
• The Trap: Many graduates think, “I have no experience, so I must write more to explain myself.” This is wrong. You write less, but make it more strategic.
• What to Cut:
  • Your primary school, secondary school, or WAEC/NECO grades.
  • Long, philosophical sentences about your “passion for learning.”
  • Irrelevant hobbies.
• What to Focus On (to fill the page concisely):
  1. Your FYP (Final Year Project): Frame it as a project you managed. (“My research on… taught me data analysis skills using SPSS…”).
  2. Your SIWES/IT: Pull 1-2 specific achievements. (“During my 6-month SIWES at [Firm], I assisted with… and was commended for my speed in learning [Software].”).
  3. Your NYSC (PPA & CDS): Frame it as a job. (“As a teacher, I managed a ‘classroom' of 45 ‘clients' and improved test scores… As my CDS project lead, I managed a ‘team' of 10 and a ‘budget' of N50,000…”).

Your letter will be one page, focused on potential, leadership, and teachability, proven by your academic and service experience.

Scenario 2: How Long for an Experienced Professional (5-15+ Years)?

• Length: One Page. (Approx. 300-400 words).
• The Trap: “I have 15 years of experience! I can't fit it on one page!”
• The Solution: You are not supposed to. Your cover letter is not a summary of your 15-year career. Your CV is. Your cover letter is a targeted argument for why your most relevant 2-3 achievements make you the perfect fit for this specific job.
• What to Cut:
  • Your first job from 15 years ago.
  • Your university degree details (just one line: “My MBA from LBS…”).
  • Every single achievement.
• What to Focus On:
  1. Read the job description.
  2. Find their #1 problem (e.g., “need to expand into Ghana”).
  3. Use your body paragraph to show how you've already solved that exact problem.
  • Example: “I see you are looking to expand your operations into Ghana. In my current role at [Competitor], I led the successful launch of our Accra office, building a team from 2 to 15 and achieving profitability in 11 months. This is the exact experience I wish to bring to your team.”

Scenario 3: Is a 2-Page Cover Letter EVER Acceptable?

This is a major long-tail keyword: “is a 2-page cover letter too long?”

Answer: Yes, 99% of the time. A 2-page cover letter is a huge red flag.

The 1% Exception:

• High-Level Academia: Applying for a Lectureship, PhD, or Professorship. These letters are often longer (1.5 – 2 pages) because they must detail research, publications, and teaching philosophy.
• High-Level Federal Government (Old-School): For some very senior, formal roles in traditional ministries, a longer, more formal letter might be expected. But this is a dying trend.
• Internal Promotion (C-Suite): If you are applying for a C-suite role within your own company, a longer, detailed memo-style letter outlining your 10-year strategy might be appropriate.

For 99% of you reading this (applying to a bank, tech firm, NGO, FMCG, oil & gas): Stick to one page. No exceptions.

Special Cases (Email, Academic, Cold-Calling)

Case 1: The Email Cover Letter

• What it is: When the job advert says, “Paste your cover letter in the body of the email.”
• Ideal Length: Even shorter! 100-150 words.
• Format: 2-3 short paragraphs.
  • Para 1: The hook. (The role + your #1 selling point).
  • Para 2: Your proof. (Your 1-2 best achievements with numbers).
  • Para 3: The CTA. (“My full CV is attached. I look forward to hearing from you.”).
• Why? People have zero patience for long emails. Be direct, punchy, and get them to open the attachment.

Case 2: The Academic Cover Letter

• What it is: Applying for a Master's, PhD, or teaching/research position.
• Ideal Length: 1.5 to 2 pages.
• Why? This is the main exception. You are expected to “expatiate.” You must detail:
  • Your research interests and how they align with the professor's.
  • Your past research projects and publications.
  • Your teaching philosophy.
  • Your specific qualifications for the program.
• This is not a business letter; it's an academic proposal.

Case 3: The “Cold” Cover Letter (Letter of Interest)

• What it is: Sending a letter to a company that has not advertised a job.
• Ideal Length: One Page, but on the shorter side (250-300 words).
• Why? You are an uninvited guest. You must be exceptionally polite, quick, and value-packed.
• Format:
  • Para 1: Hook. (Acknowledge you're cold-calling, but you admire them so much… and you have [X skill]).
  • Para 2: The “Value Prop.” (“I see your company is doing [X]. My skill is [Y], and I have an idea for how you could [achieve Z].”).
  • Para 3: The CTA. (A polite, no-pressure request for a 10-minute chat. “I've attached my CV for your reference. Would you be open to a brief chat next week?”).

15 “Sins” That Make Your Cover Letter Too Long (And How to Fix Them)

You're on page 2. You need to cut 200 words. Where do you start? Here are the 15 most common “fluff” and “filler” mistakes.

1. The “Life Story” Intro: “Ever since I was a child…” / “I graduated from…”
   • Fix: Cut it. Start with your current value.
2. Rehashing Your CV: “I worked at A, then B, then C…”
   • Fix: Assume they've read your CV. Your letter is for context and persuasion.
3. Listing Duties, Not Achievements: “My job was to manage reports…”
   • Fix: Change to achievements. “I automated the reporting process, saving 10 hours/week.”
4. The “Begging” Tone: “I humbly plead…” / “I desperately need…”
   • Fix: Cut all of it. Replace with one confident sentence.
5. Empty “Buzzwords”: “I am a hardworking, results-driven, motivated, dynamic, team-playing go-getter…”
   • Fix: Cut all adjectives. Show it with an achievement. (Don't say you're “results-driven”; say “I increased sales by 30%”).
6. Wrong Font Size: Using 14pt font to fill the page, or 9pt to cram it all in.
   • Fix: 10.5, 11, or 12pt.
7. Wrong Margins: Using 2-inch margins (too empty) or 0.5-inch margins (too dense).
   • Fix: 1-inch (2.54cm) on all sides.
8. Not Using Bullet Points: A dense 10-line paragraph is hard to read.
   • Fix: Break that paragraph into an intro sentence and 2-3 bullet points for your achievements.
9. Explaining Your University: “I attended the University of Lagos, a prestigious institution in Nigeria, where I studied…”
   • Fix: “My B.Sc. in Economics from the University of Lagos…”
10. Explaining a Career Gap: “I was out of work in 2023 due to…”
    • Fix: Cut it! A cover letter is a sales document, not a confession. Save that explanation for the interview (if they even ask).
11. Archaic Language: “I wish to state my intention…” / “Further to our…”
    • Fix: Use modern, professional language. “I am writing to…”
12. Including “References”: “References: Dr. T. Bello…”
    • Fix: NEVER put this on a cover letter or CV. It's a waste of space. They will ask if they need them.
13. Including “Personal Info”: “Date of Birth: …” / “LGA: …” / “Marital Status: …”
    • Fix: Cut immediately. It's irrelevant, unprofessional, and can lead to bias.
14. Using a Fancy Template: Using a template with a huge header, graphics, or a photo.
    • Fix: These waste valuable space. Stick to a clean, standard, text-only format.
15. Waffling / Repeating Yourself: “As I said before…” / “To reiterate…”
    • Fix: Say it once, say it well. Be ruthless. Every sentence must have a purpose.

Length is a Sign of Respect

Your cover letter length is not just about a word count; it's about respect.

A concise, powerful, one-page letter respects the recruiter's time. It respects the company's needs (by being relevant). And it respects your own achievements (by presenting them as high-impact highlights, not a boring list).

In the competitive Nigerian job market, you don't win by being the loudest (longest). You win by being the clearest and most compelling.

Go back to your two-page letter. Be brutal. Cut the fluff. Focus on the 2-3 things that prove you are the person for this job.

Your one-page advert is waiting. Go and write it.
