Scale and proportion can be used in graphic design to create a variety of effects. For example, in logo design, scale and proportion can create a memorable and distinctive identity, such as using a large scale for the symbol and a smaller scale for the name, or using a proportional relationship between the elements. In a poster design, scale and proportion can be used to create a powerful and persuasive message, such as using a large scale for the headline and a smaller scale for the details, or using a proportional division of space for the layout. Similarly, in web design, scale and proportion can create a user-friendly and intuitive interface, such as using a larger scale for the navigation and a smaller scale for the content, or using a proportional grid system for the structure.
