When it comes to describing the size of objects, the term "cookie-sized" is quite common. However, there are some alternative synonyms that can be used to convey similar size dimensions. One could use words like "biscuit-sized," "cracker-sized," or "petit-four-sized" if referring to a small, bite-sized item. For a slightly larger but still compact object, one could use phrases such as "deck of cards-sized" or "hockey puck-sized." If you're describing something that is between the size of a cookie and a full meal, you might want to use "appetizer-sized" or "tapas-sized." Regardless of the synonym chosen, the goal is to accurately convey the size of the object in question.
