When classes take on too many responsibilities, they grow. A large number of instance variables or methods can make a class hard to understand. Large classes tend to have lower cohesion and higher churn.

Often large classes have methods that do not operate on all of the class state. Identifying the groups of data that are used together can point to seams to split out additional collaborator classes or value objects.

Another trick is to look for repeated prefixes or suffixes in method and variable names, or repeated parameter names, and use them to guide extractions.

Long or complex methods can make code harder to understand. In most circumstances, methods are best as a small chunk of code (the "how") with a clear, understandable name (the "what"). Long methods can also lead to duplication, as it's harder to reuse logic that is tightly coupled to surrounding code.
