You’ve probably heard that the cover letter is dead. Honestly, some recruiters will tell you they never even open the attachment. But then you talk to a hiring manager at a boutique firm or a high-stakes tech company, and they'll tell you the exact opposite. They’ll say a poorly formatted letter is the fastest way to the "no" pile. It's weird. We're in 2026, and we're still obsessing over margins and font sizes, but that’s because proper cover letter format is basically a proxy for "does this person actually give a damn about the details?"
If you mess up the header or use a font that looks like a wedding invitation, you're signaling that you don’t understand professional norms. It’s not just about the words. It’s about the visual architecture.
The Header Is Your Business Card
Don't overthink this, but don't under-think it either.
Your contact information needs to be at the very top. You'd be surprised how many people forget to include their phone number or use an email address from 2005 that involves a nickname and way too many underscores. Just use your name, a professional email, your city and state—you don’t need your full street address anymore, privacy is a thing—and your LinkedIn profile URL.
Below your info, put the date. Then, the recipient’s info. This is where it gets tricky. If you can find the name of the hiring manager, use it. "Dear Hiring Manager" is fine, but "Dear Sarah Jenkins" is better. Use LinkedIn or the company "About Us" page to hunt for that name. It shows you did the work. If you absolutely cannot find a name, "Dear [Department] Hiring Team" is way better than the ghostly, Victorian-sounding "To Whom It May Concern."
The Visual Rhythm of a Winning Letter
White space is your best friend. Seriously.
If I open a document and it’s just a massive wall of text from edge to edge, my brain shuts off. I’m not reading that. Neither is a recruiter who has 400 other applications to get through before lunch. You want your margins to be one inch all around. Use a standard font like Arial, Calibri, or Georgia. Size 10 or 12. Anything smaller and you’re asking for an eye strain lawsuit; anything larger and it looks like a middle school essay where you're trying to hit a page count.

Keep your paragraphs short. Some should be two sentences. Others might be five. This creates a visual "flow" that keeps the reader moving down the page.
Most people think they need to fill the entire page. You don't. A cover letter that is three-quarters of a page long is often more effective than one that hits the very bottom. It shows brevity. It shows you can get to the point.
Why the "T-Format" Is a Secret Weapon
There’s this thing called the T-format cover letter that career experts like Liz Ryan have championed for years. It’s not a strict rule, but it’s a brilliant way to handle proper cover letter format when you’re applying for a role that has very specific, technical requirements.
Basically, you have your intro paragraph, and then you create a section that explicitly matches your skills to their needs. You might say, "You mentioned you need someone with five years of Python experience; I’ve spent the last six years building backend systems for fintech startups."
By breaking the traditional "story" format into these direct "Requirement vs. My Experience" beats, you make it impossible for them to ignore your qualifications. It’s bold. It's direct. It's also much easier for an Applicant Tracking System (ATS) to parse if it's formatted simply without weird columns or graphics.
The Three-Act Structure That Actually Works
The middle of your letter shouldn't just repeat your resume. That’s a waste of everyone’s time. Your resume is the "what," and your cover letter is the "why" and the "how."

- The Hook: Start with why you love the company or a specific project they recently finished. Maybe you saw their CEO speak at a conference, or you've used their software for years. Be genuine.
- The Evidence: Pick one or two "hero stories." These are specific moments where you saved money, made money, or solved a massive headache. Use numbers. "I increased efficiency" is boring. "I reduced the server lag by 40% during peak hours" is a story.
- The Call to Action: Don't be passive. Instead of "I hope to hear from you," try "I'd love to discuss how my background in X can help your team achieve Y."
Modern Formatting Nuances You Can't Ignore
We have to talk about the "Save As" button.
Always, and I mean always, save your file as a PDF unless the job posting explicitly asks for a Word doc. Word docs shift. Fonts disappear. Margins move. A PDF is a freeze-frame of your work. Also, name the file something smart. Cover_Letter_Final_v2.pdf is amateur hour. Firstname_Lastname_Cover_Letter_Company.pdf is how a pro does it.
Acknowledge the reality of the digital age: your cover letter might be the body of an email. If that's the case, the proper cover letter format changes slightly. You don't need the physical header with addresses. You jump straight to the salutation. But the core principles—brevity, white space, and evidence-based storytelling—remain the same.
Real Talk on "Professionalism"
There’s a balance between being professional and being a robot.

I’ve seen letters that are so formal they feel like legal depositions. "I am writing to express my fervent interest in the aforementioned position." Nobody talks like that. It’s okay to sound like a human. You can say, "I've been following your company's growth in the renewable energy sector, and honestly, the way you handled the recent grid integration project was impressive."
That sounds like a person. Recruiters hire people, not algorithms.
Actionable Steps for Your Next Draft
Stop looking at "standard" templates that were designed in 1998. They're cluttered and ugly.
- Start with a clean, blank document. Set your margins to one inch.
- Choose a clean sans-serif font like Roboto or Open Sans if you want a modern look, or a classic serif like Garamond for something more traditional.
- Write your header. Check your LinkedIn URL to make sure it actually works.
- Draft an opening that mentions a specific person or a specific company achievement.
- Identify two "wins" from your career that directly relate to the job description. Write them as short, punchy paragraphs.
- Check your paragraph lengths. If you see a block of text longer than six lines, break it up.
- Save the file as a PDF with a clear, professional name.
- Read it out loud. If you run out of breath during a sentence, that sentence is too long. Fix it.
The goal isn't just to follow a template. It's to create a document that feels intentional. When a hiring manager sees a perfectly formatted, easy-to-read letter that speaks directly to their pain points, you've already won half the battle. You aren't just an applicant anymore; you're a solution.
Don't let a weird margin or a "To Whom It May Concern" kill your chances before they even get to your resume. Get the format right, then let your experience do the talking.
