How are records measured?


If your record idea is approved, we’ll send you the guidelines for your attempt. Your guidelines are unique to your record and explain:


What the record is for and who can attempt it
The rules you must follow
How we measure the record
What evidence you need to provide

You’ll find your guidelines on your account page as a link under your record title. You can also download them as a PDF and share them with everyone involved in your attempt – participants, organisers and independent witnesses. It’s vital that everyone reads and understands the rules/guidelines before the attempt. If any rule is broken, your attempt may be disqualified and nobody wants that to happen.

Every Guinness World Records title is measured in a clear, fair way so that everyone attempts it under the same conditions. That’s why you must make an enquiry and wait for your official guidelines before you make your attempt.

Most records are verified by uploading evidence for our Records Management Team to review. For some attempts, you can have an official Guinness World Records Adjudicator at your event.

An Adjudicator:

  • Checks your guidelines with you on the day
  • Observes the attempt to make sure all rules are followed
  • Reviews the measurements and evidence in real time
  • Announces the result there and then
  • Presents the official certificate if you are successful

Having an Adjudicator present is a paid-for service. If you want to know more about it then select the option of adjudication when you are enquiring about your record.

Whether your record is verified by uploaded evidence or in person by an Adjudicator, the goal is the same: to be certain that when we say something is a world record, it really is the best in the world.
