When something is out of proportion, it means it is not in accordance with the correct or proper size, quantity, or ratio. There are several synonyms that can be used to describe this condition, such as disproportionate, imbalanced, unequal, excessive, exaggerated, too much, and intemperate. Each of these words conveys slightly different connotations, but all refer to something that is not correctly proportioned. For example, if someone's reaction to a minor event is disproportionate, it means the reaction is more intense than is appropriate for the situation. Similarly, if an item in a display is excessive or exaggerated, it means it is too large or ostentatious for the space or context in which it is presented.
