As per the guidelines of the Indian Mountaineering Foundation (IMF), a porter shall not carry more than twenty-five (25) kilograms of load per day for a distance of up to ten (10) kilometers. However, distance covered may vary with the altitude and difficulty level of the route. The load limit decreases with an increase in altitude as given below:
12-kilogram load per porter at altitude above 7,000 meters
15-kilogram load per porter at altitude ranging from 7,000 to 6,001 meters
20-kilogram load per porter at altitude ranging from 6,000 to 5,001 meters
25-kilogram load per porter at altitude up to 5,000 meters
Thus, climbers shall carefully estimate total number of porters required for an expedition to the Indian Himalaya.
