How to Write a Cover Letter (2026 Guide)

A professional cover letter follows a clear structure that hiring managers expect. Start with your contact information at the top, followed by the date and the employer's details. Then include a greeting, three to four body paragraphs, and a professional closing. The standard cover letter length is one page roughly 250 to 400 words. Anything longer risks losing the reader's attention, while anything shorter may seem incomplete. Use a clean, readable font such as Calibri, Arial, or Garamond at 10.5 to 12 points. Set margins between 0.75 and 1 inch on all sides. Keep paragraphs concise, ideally three to five sentences each. White space matters a wall of text is harder to read than well-spaced paragraphs. Your header should match your resume header so the two documents look like a coordinated package. If you are submitting digitally, save as PDF to preserve formatting across devices.

Formatting determines whether your cover letter looks professional at first glance. Use single line spacing within paragraphs and add a blank line between each paragraph. Align all text to the left block formatting is the standard for business correspondence. Bold the company name or role title only if you want to draw attention to them, but avoid excessive formatting. Do not use bullet points in a cover letter. Unlike a resume, your cover letter should flow as natural paragraphs that tell a compelling story. Avoid colors, graphics, or unusual fonts. The goal is readability, not design flair. If you are emailing your cover letter as an attachment, name the file clearly: FirstName-LastName-Cover-Letter.pdf. If pasting into an email body, strip all formatting and use plain text. Many applicant tracking systems strip formatting anyway, so simple is always safer.

Your opening paragraph determines whether the hiring manager keeps reading. Start by naming the specific position you are applying for and where you found it. Then immediately follow with your strongest qualification or most relevant achievement. Avoid generic openings like 'I am writing to apply for the position of...' the hiring manager already knows that. Instead, lead with impact. For example: 'When I saw the Senior Product Manager role at Stripe, I knew my experience scaling B2B payment products from $2M to $18M ARR would make me a strong fit.' Mentioning a referral, a recent company achievement, or genuine enthusiasm for the company's mission can also create an immediate connection. The opening should answer one question: why should this person keep reading? If you can hook them with a specific result or a direct connection to their needs, you have already outperformed most applicants.

The body of your cover letter typically one to two paragraphs is where you make your case. Each paragraph should focus on a single theme: a key achievement, a relevant skill set, or a direct connection between your experience and the job requirements. Use the STAR method (Situation, Task, Action, Result) to structure your examples. Do not simply repeat your resume. Instead, expand on one or two achievements that are most relevant to the role and explain the context behind them. For instance, if your resume says 'Increased conversion rate by 40%,' your cover letter can explain how you identified the problem, what strategy you implemented, and what it meant for the business. Quantify wherever possible. Numbers make your claims concrete and credible. Mirror the language from the job description to show alignment with the employer's priorities, but do not copy phrases verbatim. Show that you understand the company's challenges and position yourself as the solution.

Your closing paragraph should accomplish three things: restate your enthusiasm for the role, summarize your value proposition in one sentence, and include a clear call to action. Avoid passive closings like 'I hope to hear from you.' Instead, write something confident: 'I would welcome the opportunity to discuss how my experience in enterprise sales can help Acme Corp exceed its Q3 revenue targets. I am available for a conversation at your convenience and can be reached at (555) 123-4567.' Thank the reader for their time and sign off with a professional closing such as 'Sincerely,' 'Best regards,' or 'Respectfully.' Follow your closing with your full name. If submitting a physical letter, leave space for a handwritten signature. For digital submissions, a typed name is sufficient. Avoid post-scripts or additional notes after your signature they look unprofessional.

Seeing real examples helps you understand how the principles above work in practice. A strong cover letter for a software engineering role might open with a specific technical achievement, reference the company's tech stack, and close with enthusiasm for the engineering culture. A marketing cover letter might lead with campaign metrics, connect them to the company's growth stage, and offer to bring a specific strategy to the team. The key pattern across all effective cover letters is specificity generic letters that could be sent to any company are immediately obvious to hiring managers. Every sentence should be tailored to the specific role and company. Use our cover letter examples as starting points, then customize heavily for each application.
