Basic Origami Symbols

Below are the basic origami symbols used in diagrams throughout this site.  These symbols, or origami expressions, are based upon those developed by Akira Yoshizawa and modern internationally recognised conventions.  These are the ‘language’ of origami.

In 1991 Robert Lang published an excellent series of articles on diagramming conventions for the Friends of the Origami Center of America (now OrigamiUSA) recommending a standard set of origami symbols.  This would update the symbols originally devised by Akira Yoshizawa to account for modern folding and diagramming techniques, and reduce the number of variations that had arisen. Lang’s articles have since been published on his website

The basic origami symbols used on this site largely conform to Lang’s recommendations.
