Carpet weaving, as an ancient art in Iran, is commonly divided into two components: the field and the border, based on pattern structure. In certain carpet types, especially those from the Timurid era, borders serve as a vital stylistic element for proper understanding and classification. Consequently, the importance of borders in Timurid-style carpets underscores their critical role in facilitating comprehension of this art. Intact examples of these carpets are limited, heightening the significance of remaining images as a documentary source for recognizing this art. This qualitative research leverages these sources and, through a descriptive-analytical method, aims to identify types of borders in Timurid-style carpets based on visual structure. The research findings indicate that these border types can be classified into four main groups and eleven subgroups: 1. Borders composed of interlocking knots (with the main element being the destiny knot, with the main element being the hooked knot) 2. Borders composed of destiny knots or composed of hooked knots (destiny knot, composite knot, combinable knot) 3. Islamic borders (mihrab-shaped, candlestick-shaped, complete Islamic) 4. Simple borders (geometric, geometric-rotational).
