Estimate your backpacking base weight by adding your non-consumable gear, including backpack, shelter, sleep system, clothing, cook kit, electronics, safety gear, and other packed equipment. This calculator also shows your big three weight, ultralight category, and how much consumable weight gets added separately.
Base weight:
Base weight is the weight of non-consumable gear carried inside or attached to your backpack. It does not include food, water, fuel, or worn clothing.
Big three:
The big three usually means your backpack, shelter, and sleep system. Reducing these items can make a large difference in total pack weight.
Total starting pack weight:
Food, water, and fuel are added separately to estimate what your pack weighs at the beginning of the trip.
A base weight calculator helps you understand how much your backpacking gear weighs before consumables are added. It is useful for gear shakedowns, ultralight planning, comparing trip setups, and finding which categories add the most weight.
A lower base weight can help, but the best setup still depends on weather, terrain, safety needs, comfort, water availability, and trip length.
The basic base weight formula is:
Base Weight = backpack + shelter + sleep system + packed clothing + cook kit + electronics + safety gear + other non-consumable gear
Backpacking base weight is the weight of your backpack and non-consumable gear, excluding food, water, fuel, and worn clothing.
A common guide is under 10 pounds for ultralight, 10 to 20 pounds for lightweight, 20 to 30 pounds for traditional, and over 30 pounds for heavy base weight.
No. Food is a consumable, so it is not usually included in base weight. It is included in total starting pack weight.
The big three usually refers to backpack, shelter, and sleep system. These are often the heaviest non-consumable gear categories.
