The idea behind Pecha Kucha is to keep presentations concise, the interest level up and to have many presenters sharing their ideas within the course of one night. Therefore the 20x20 Pecha Kucha format was created: each presenter is allowed a slideshow of 20 images, each shown for 20 seconds. This results in a total presentation time of 6 minutes 40 seconds on a stage before the next presenter is up.
