Introduction: The three important articulating facets in the superior aspect of the calcaneum are the anterior, middle and posterior articulating facet. Descriptions of the posterior talar facet on the dorsum of the calcaneus are similar. However, there are differences when facet for the head of the talus on the calcaneus is considered. Four types (pattern I, II, III, IV) of calcaneus having different talar facets are reported in the literature.

Objective: This study aims to describe the calcaneal bone by measuring its dimensions and determining the variations of talar articulating facet.

Materials and methods: Overall 142 calcanei (68 right, 74 left) with unidentified gender, were assessed. Vernier calipers and Goniometry were used.

Results: In this study Type I calcaneus (56.34 %) was the most prevalent type with Type II calcaneus (42.25 %) as the second most common type followed by Type IV (1.41 %) as the third frequently found pattern of calcaneus.

Conclusion: Type I calcaneus was the most frequent type in the Nepalese showing similarity to the results of  the studies performed in Spanish,  American, African and various Indian population. Bohler’s angle of the right and left calcanei was 34.920 ±8.090 and 35.40 ±7.300 respectively. Development of database of calcaneal measurements in various populations is recommended.
