Key takeaways

Increasingly, cover letters should be a half page and connect the impact you've had in past roles to the needs of the one you're applying to.

  • While many employers don't require cover letters, including one can be a useful addition to your overall job application.

  • Increasingly, cover letters need to be short, show that you understand the needs the open role is trying to address, and connect your experience to those needs.

  • More employers are foregoing cover letters for short-form response prompts, but they screen submitted answers for AI usage.

How long should a cover letter be for a job? 

At most, a cover letter should be one page. However, it's becoming increasingly common to submit a cover letter that's much shorter.

Once an application makes it past an applicant tracking system (ATS) for human review, recruiters typically don't spend significant time reviewing each candidate's materials just yet. That means a cover letter has to grab their attention—and fast. A half-page cover letter means you know which of your accomplishments address the needs the open role is trying to solve.

Tips for drafting an effective short cover letter

Overly long cover letters that use a chronological approach to retell a resume aren't as effective. Instead, aim for a quick synthesis that shows you understand the problems the open role is addressed with solving—and how your experience fits those needs.

Since you aren't drafting as long of a cover letter, space will be tighter. By leading with quantifiable metrics and specific achievements, you'll more quickly prove your business value.

Follow the tips below to craft a brief and impactful cover letter:

  • Aim for impact over length: Keep the total word count around to around 250 words, ensuring it easily fits on half a page with plenty of clean white space.

  • Include metrics: Use your limited space to highlight specific, data-backed wins, such as "increased team efficiency by 20 percent" or "improved customer resolutions by 13 percent in one quarter."

  • Know the needs the job is trying to solve: Every key win should directly answer a specific pain point mentioned in the job posting.

Do employers still want cover letters?

While cover letters are now an optional part of many job applications, including one can still be helpful. If your application makes it through that screening and gets reviewed by a human resources (HR) professional, including a cover letter can be an opportunity to clarify what you're looking for, what you've accomplished at your last role, and your potential fit.

The rise of short-form response prompts

Many modern employers have started asking candidates to complete two to five targeted, short-form questions as part of their application. These micro-responses, which can range from 100 to 250 words per answer, act as an additional screening layer.

While many of the questions have to do with some aspect of the role and are meant to learn how you might approach the work, you may also find questions that seek to understand your critical thinking, problem-solving, and decision-making skills.

Sample prompts:

  • Customer support: Tell us about a time when you needed to troubleshoot a customer’s technical issue without pre-existing documentation.

  • Marketing: How do you diagnose and address an underperforming marketing channel?

  • Design: When was a time when you went above and beyond to make a user happy?

  • Sales: How do you balance volume with quality in your sales outreach?

To stand out in a short-form format, treat each response like a mini-interview answer, using frameworks like the STAR method (Situation, Task, Action, Result) to deliver a concise, evidence-based response.

Screening for AI in cover letters

As candidates increasingly use LLMs to draft cover letters and short-form answers, hiring teams have sought to run AI detection software or API integrations within their ATS to flag writing that may have come from AI.

When an application features flawlessly structured prose that lacks any real human voice, specific cultural context, or deep personalization, it is immediately flagged as low-effort spam. For a candidate, having your responses identified as pure AI output will often lead to the rejection pile because it signals a lack of genuine interest in the specific role and company.

Navigating this new screening landscape requires a hybrid approach. Consider using AI responsibly for brainstorming, outlining, or proofreading, but keep the actual writing deeply personal. If your short-form response includes highly specific data points, hyper-local company references, and a conversational tone unique to your actual work history, you shouldn't have to worry about getting flagged as AI.
