The Penrose Stairs, also known as the endless staircase, is one of my favorite optical illusions. In this post, I wanted to share my own versions of the famous never-ending stairs. I created these impossible objects using Adobe Illustrator and an isometric grid. If you’d like to use any of these illustrations for your personal or educational projects, you’re welcome to do so, but please don’t use them for commercial use. I’ve also included a Penrose Staircase printable puzzle activity. Cut out the shapes and piece them together to make the endless stairs.

About Lionel Penrose and the Penrose Stairs
Lionel Penrose was a British Psychiatrist and mathematician. Penrose created the Penrose Stairs with his son Roger in the 1950s. They had been inspired to create their own “impossible objects” after seeing the work of M.C. Escher. While Escher had created other optical illusions, he had not yet created an endless staircase. When he learned about the Penroses’ creation, he incorporated it into the artwork titled, “Ascending and Descending.”
A variation of the Penrose Stairs is the Penrose Triangle.
