Assuming that is a commutative ring with unity, and be a left unitary -module. This work presents a generalization of the concepts of compressible and retractable modules. We specifically define and examine r-small compressible and r-small retractable modules. We examine their essential aspects, offer characterizations, and present instructive examples. Additionally, we investigate the relationships between these novel classes and existing established types of modules.
