How Long Should a Cover Letter Be?
You have found the perfect role, you are keen to make a strong impression, and now you are staring at a blank page wondering how much to write. Too short and you seem to have made no effort. Too long and the reader gives up before your best point. It is a genuinely tricky balance.
So how long should a cover letter be? The short answer is one page, and usually rather less than that. The longer answer, which will actually help you write a better letter, is below.
The Ideal Cover Letter Length
A cover letter should fit comfortably on a single side of A4. In practice that means roughly 250 to 400 words, arranged in three or four short paragraphs. Anything longer risks losing the reader, and anything much shorter often means you have not made a proper case for yourself.
Think of it as a taster, not a full meal. Your CV carries the detailed history. The cover letter’s job is to make a hiring manager want to read that CV closely and picture you in the role. It should take under a minute to read.
A useful mental model: three or four tight paragraphs, each doing one clear job, with white space around them so the page feels inviting rather than dense.
Why One Page Is the Sweet Spot
Recruiters are busy and often working through a large stack of applications. A concise letter respects their time and signals that you can communicate clearly, which is itself a workplace skill worth demonstrating.
There is also a psychology to it. A short, confident letter reads as though it was written by someone who knows their value and does not need to over-explain. A sprawling one can suggest uncertainty, as though you are hoping that volume will make up for focus. Brevity is quietly persuasive.
Keeping to a page also forces useful discipline. When space is limited, you are far more likely to lead with your strongest, most relevant points rather than everything that crossed your mind.
What Belongs in Each Paragraph
Structure is what lets you stay short without leaving anything important out. A reliable shape looks like this:
- Opening. State the role you are applying for and offer a sharp, specific reason you are a strong fit. Skip the throat-clearing.
- Middle (one or two paragraphs). Give your best evidence. Pick one or two achievements that map directly onto what the advert asks for, with a result attached.
- Closing. Reaffirm your enthusiasm, mention that your CV holds further detail, and end with a warm, confident sign-off.
Each paragraph should earn its place. If a sentence does not move you closer to an interview, it is a candidate for the cut. For a fuller breakdown of the essential ingredients, our guide on what to include in a cover letter sets out each element in turn.
How to Cut the Waffle Without Losing Substance
Most first drafts are too long, and that is completely normal. The skill is in the edit. Here is where the wasted words usually hide:
- Empty openers. “I am writing to apply for the position of” can almost always be sharpened into something more direct.
- Restating your CV. The letter should interpret your experience, not repeat it line for line.
- Filler phrases. “I believe that I would be”, “as you can see from my CV”, “I am confident that”. Cut them and the sentence usually reads stronger.
- Over-qualifying. Words like really, very, quite and just often weaken rather than add.
Read your draft aloud. Anywhere you stumble or feel your attention drift is a place to tighten. If you can say something in six words instead of twelve, do.
When a Little More Length Is Justified
Occasionally a slightly fuller letter makes sense, for instance a senior role, an academic post, or an application that explicitly asks you to address specific criteria. Even then, stay on one page and let relevance, not volume, guide you. A longer letter still has to justify every line.
Length Is Not the Only Thing That Counts
It is worth remembering that a perfectly sized letter can still fall flat if the content is generic. Length gets you in the door, but impact comes from tailoring, evidence and a genuine connection to the specific role and organisation.
Aim for a letter that could only have been written by you, for this job, at this company. That is what turns a correctly formatted page into a memorable one. Our collection of tips to help your cover letter get noticed covers the finer points of tone, personalisation and impact that lift a good letter into a great one.
So hold yourself to the one-page rule, then spend your energy making every one of those words work hard.
Getting the length right is the easy part. Making a short letter genuinely compelling is where the craft lies, and it is exactly what our writers do every day. If you would rather have a professional shape yours to perfection, put your cover letter in expert hands and give yourself the strongest possible start.
