Proporcionális is a term that can refer to several concepts, often related to proportionality or a balanced relationship between parts. In mathematics, it signifies a constant ratio between two quantities. When one quantity changes, the other changes by the same factor, maintaining their proportional relationship. This is fundamental in understanding scaling, ratios, and direct variation.

In political science, proportional representation is a electoral system designed to allocate legislative seats in proportion to the votes each political party receives. This system aims to ensure that the composition of the legislature more accurately reflects the electorate's preferences, potentially leading to greater diversity of representation and reducing the prevalence of "wasted" votes. Different methods exist for implementing proportional representation, such as party-list systems or mixed-member proportional systems.

The concept also appears in art and design, where the idea of proportional balance is crucial for aesthetic harmony. Achieving proper proportions can contribute to a sense of stability, realism, or visual appeal in a composition. This might involve the Golden Ratio or other established principles that guide the relative sizes of elements within a work. The application of proportional principles can vary widely depending on the style and intent of the artist or designer.
