How Long Should a Case Study Be?

What you need to include in your story will depend on the type of discipline. For example, a kitchen remodeling company could tell its entire story with pictures. Whereas this approach may not be suitable for a software invoicing solution.

Consider this pro advice while crafting your case study:

• Most sources indicate that it should consist of 500-1500 words.
  
• To ensure that your message is concise and crystal clear, add a brief snapshot section of 100 words or less.
