Symmetrizing is defined as the process of making something symmetrical or balanced. The antonyms of the word symmetrizing are asymmetry and disproportion. Asymmetry refers to the lack of balance or symmetry in something. It means that the two sides of an object or an image are not identical, and there is a significant difference between them. Disproportion, on the other hand, means that something is not in proportion or harmony. It refers to the imbalance or inequality in size, shape, or amount of something. While symmetrizing is about creating harmony and balance, asymmetry and disproportion are all about imbalance and disharmony.
