Blattgröße
Blattgröße (German for "leaf size") refers to the dimensions or surface area of a plant leaf and, in other contexts, the size of a sheet in printing and papermaking. In botany the term is used to describe individual leaf area, length and width, and overall form; in industry it denotes standard sheet formats and dimensions.
In plant science, Blattgröße is measured as leaf area (commonly in cm² or mm²) using tools such
Leaf size influences and reflects ecological and physiological processes including light capture, transpiration, boundary-layer heat exchange
Applications include taxonomy, functional ecology, paleobotany (leaf physiognomy as a climate proxy) and forestry. In printing
