Using person‐environment fit theory, this article formulates a conceptual model that links work, family, and boundary‐spanning demands and resources to work and family role performance and quality. Linking mechanisms include 2 dimensions of perceived work‐family fit (work demands–family resources fit and family demands–work resources fit) and a global assessment of perceived work‐family balance. Work, family, and boundary‐spanning demands and resources are associated with the 2 dimensions of fit, which combine with boundary‐spanning strategies to influence work‐family balance, which in turn affects role performance and quality. The model provides a framework for clarifying and integrating previous conceptualizations, measures, and empirical research regarding perceived work‐family fit and balance as linkages between the work‐family interface and outcomes. The article closes with suggestions for further work.
