How to choose backpack capacity in litres

Quick answer

Use about 15–25 litres for daily commuting and school, 25–35 litres for college or a day trip with a laptop, 35–50 litres for overnight travel and 50 litres or more for multi-day treks.

Step by step

  1. List what you carry

    Laptop, clothes, lunch, water and gear each take space.

  2. Match the trip length

    Daily use needs less; overnight and multi-day trips need more.

  3. Consider weight

    Larger bags invite overpacking — choose the smallest bag that fits.
