When describing something as "ill-proportioned," there are a number of synonyms that can be used to convey the same idea. For instance, "disproportionate" is a term that can be used to describe something that is out of balance or uneven in certain aspects. Similarly, "lopsided" can be used to describe something that appears to be leaning to one side, while "awkward" suggests a lack of harmony or grace. "Unbalanced," "uneven," and "inharmonious" are also possible synonyms for "ill-proportioned," each emphasizing a different aspect of the lack of proportion. Whatever term is used, the goal is to convey a sense of disharmony or imbalance in the thing being described.
