The concept of urban resilience has been recognized in recent decades as a key indicator for assessing and designing cities resistant to crises and undesired changes, with its physical and social dimensions having the most significant impact on urban structure. Sustainable urban form plays a fundamental role in shaping resilient urban fabric, which is of great importance in urban regeneration approaches. The main aim is to investigate the effects of sustainable regeneration on urban form in the historic and worn-out fabric of Tabriz city in Iran. The research method is analytical-descriptive and considered practical in terms of purpose. Data collection was conducted through library and survey methods. Given the nature of the issue and the goal, the scale of urban form analysis was applied to the historical worn-out fabric of Tabriz, evaluated based on the extracted dimensions and presented indicators, focusing on the physical-social dimension. Accordingly, the research employed questionnaire surveys randomly among 395 residents in five neighborhoods: Charmenar, Nobar, Sanjarn, Nariman, and Vijoyeh, utilizing the AHP technique and the deviation from the optimal limit method. The findings indicate that the neighborhoods of Fourminar and Sengarān, with ARI levels of 0.49 and 0.53 respectively and the greatest resilience, show the highest resilience in the urban regeneration approach. Further studies can explore other dimensions of resilience
