How to write a cover letter in 2026: the complete guide
A cover letter makes one argument in three short paragraphs: why this company, why you, and why now. It does not summarize your resume — it connects your strongest evidence to the posting's top requirements and gives the reader a reason to look at your resume with interest instead of skepticism. Here is the whole process, with an in-depth guide for each step.
The five steps, in order
- Decide whether this application needs a letter — it clearly does if the posting asks, you are changing careers, or a named person will read it.
- Find the name — ten minutes on the posting, LinkedIn, and the team page. "Dear [Name]" outperforms every generic greeting.
- Open with your strongest relevant fact and the role name — never "I am writing to apply for..."
- Spend the middle paragraph on one or two achievements chosen to mirror the posting's top requirements, with numbers where honest.
- Close with the fit in one line and a clear next step, keep the whole letter to 250-400 words, and format it to match your resume.

Frequently asked questions
What should a cover letter say?
One argument in three short paragraphs: why this company and role (opening), the one or two achievements that prove you fit its top requirements (middle), and a confident close with a next step. It complements your resume; it never summarizes it.
How long should a cover letter be?
Between 250 and 400 words — three to four paragraphs, comfortably under one page. Hiring managers skim, and a tight letter that makes one clear argument beats a full page.
Do employers still expect cover letters?
It depends on the role. They matter most when the posting requests one, for career changers, at smaller companies, and in writing-heavy roles. For high-volume portal applications where the field is optional, a strong resume alone is acceptable.
How do I make an AI-generated cover letter sound like me?
Generate the draft against the actual job description, then edit in the details only you know: the real reason this company interests you and the specific project that maps to their needs. Two or three minutes of edits separates your letter from every unedited draft.
