How Long Should A Job Description Be?

How Long Should A Job Description Be?

If you are a small or medium-sized business owner looking to attract job seekers to an open vacancy, then writing a job description, which will form part of your job ad, is a crucial task. A great job description will attract candidates in greater numbers and the perfect job description will ensure they are qualified, at the right seniority level, and the top talent in your industry.

Job descriptions that are too short may not be taken seriously or provide enough detail to give a job seeker a basic understanding of the job posting, let alone if it is right for them. Too long, and job descriptions can be skipped over or have the job purpose and key facts lost within a mountain of text.

  • Job description length and format
  • How long should a job title be?
  • How long should a job summary be?
  • How many job responsibilities and required knowledge should I add?
  • What is the correct length for job ads?

Job Description Length And Format

Job Description Length And Format

A good job description should provide the job seeker thorough knowledge of the role on offer. When writing a job description, you should aim to achieve this in 300-500 words. Another way to judge the length of job descriptions is to aim for half an A4 sheet of typed paper or one or two screen lengths of a desktop/laptop or tablet/mobile phone screen.

The format of a job description should include job titles, job summary, job responsibilities, and required/working knowledge. To hit the sweet spot, you can make use of formatting such as short paragraphs and bullet points. You should follow good basic principles in your hiring process, so avoid internal jargon that might deter the best candidates.

How Long Should A Job Title Be?

How Long Should A Job Title Be

Job titles need to be accurate (reflect the role) and garner the attention of potential candidates. Jobs that tend to catch the eye of a prospective future employee are usually 1-3 words, comprising less than 20-25 characters. One survey discovered that more than a third of the job application decision is made by the candidate on job titles alone.

We recommend doing some keyword research on job titles, listing those with the highest volumes for each company department, and avoiding vague terms. For further insights and guidance, read our blog choosing the right job title.

How Long Should A Job Summary Be?

How Long Should A Job Summary Be

The job summary length should be between 100-150 words or 2-3 sentences. Remember, you want to grab job seekers’ attention, and too long often means unread! The job summary can include the job’s location or if it is remote, top perks, who the position reports, what makes the role unique, and details of the work environment (office based, working with hazardous materials). Reserve your list of duties for the job responsibilities section.

How Many Job Responsibilities And Required Knowledge Should I Add?

Job Responsibilities And Required Knowledge

Dedicating another 100-150 words to job responsibilities should give the best talent sufficient comprehension of essential activities. To ensure a future employee can handle the technical matters of the role, must have qualifications and specific skills are included here. Employers should also consider mentioning desirable personality traits and essential physical requirements (such as standing for long periods).

To find your ideal candidate, consider creating a list of must have and nice to have education and skills. The list can use 7-8 bullet points to give a clear, visible snapshot of jobs, and could include technical certifications, a bachelor’s degree, problem-solving, or complete mastery/comprehensive knowledge/general knowledge of X.

What Is The Correct Length For Job Ads?

Job Ad Length And Salary Range

An additional 100 words will be sufficient to turn your job description into a job ad. To help candidates understand your company and offer, your job ad should include a salary range, company name, company description (what makes your company unique), full-time/part-time, temporary/permanent, and a link to your career site.
