Balance in visual composition refers to the distribution of visual weight across an image or frame, creating a sense of stability, harmony, or intentional tension. A well-balanced composition feels visually comfortable and guides the viewer's eye naturally through the scene, while an unbalanced composition can create unease or direct focus in a specific direction.

There are several types of balance used in visual design. Symmetrical balance places equal visual weight on both sides of a central axis, creating a formal, stable feel. Asymmetrical balance uses different elements of varying size, colour, or contrast to achieve equilibrium without mirroring, often resulting in more dynamic and visually interesting compositions. Radial balance arranges elements outward from a central point, common in graphic design and certain photographic compositions.

When writing prompts for AI image or video generation, incorporating balance-related language helps guide the model toward more intentional, professional-looking compositions. Describing where subjects sit in the frame and how visual elements are distributed can significantly improve the compositional quality of AI-generated content.
