Average backpack weight for hiking

The average backpack weight for hiking can vary depending on several factors, such as the duration of the hike, the climate, the terrain, personal preferences, and the individual’s level of experience and fitness. However, as a general guideline, hikers often aim to keep their backpack weight between 10% and 20% of their body weight.

For a day hike or a short overnight trip, where you only need to carry essentials like water, food, extra clothing, and basic gear, a backpack weight of around 10% of your body weight is typically sufficient. For example, if you weigh 150 pounds (68 kilograms), your backpack should ideally be around 15 pounds (6.8 kilograms) or less.

It’s important to note that these are general guidelines, and personal preferences and physical capabilities may influence the ideal backpack weight for each individual. It’s recommended to gradually increase your backpack weight during training hikes to gauge your comfort level and adjust accordingly. Additionally, investing in lightweight gear and efficient packing techniques can help reduce the overall weight of your backpack and make your hiking experience more enjoyable.
