Guido Winkler is an artist based in Leiden, the Netherlands. His work is based on the difference between the visual and physical space. He creates wooden panels, often with tapered sides or, in turn, folded into the third dimension, at times they become sculptural installations or wall paintings. The work sits somewhere in between painting and object, often trying to find ways to shift the perspective and space in ways alternatively to the known classical renaissance perspective.

In 2007 together with his wife Iemke van Dijk, he founded the exhibition space IS-projects, in Leiden. Since its initiation the IS collaborated with Supermarket Art Fair Stockholm, The GKG in Bonn, Transmitter in New York and Platforms Project in Athens, to name a few. Among its major projects the IS curated the exhibition Open Air Museum De Lakenhal, 100 years after De Stijl in 2017. Since 2020, the IS has successfully continued to work under the frame of the EST art foundation.

Winkler had solo exhibitions at A Gallery Named Sue in The Hague and Concrete Store in Amsterdam. His work has been shown in numerous exhibitions in galleries, artist run spaces, museums and on art fairs. His work was shown at the first biennial of Non-Objective art in Grenoble, the first biennial Ortogonal in Sofia, the Biennial Roadshow during the 56th Venice biennial and Free Manifesta during Manifesta IV at the Museum für Moderne Kunst Frankfurt A.M.
