For general guidance; adjust based on personal comfort and health.
Examples
- 72 kg hiker carrying an 11 kg pack ⇒ 15.28% of body weight

FAQ
What is a safe backpack ratio?
Outdoor recreation guides typically suggest keeping the ratio under 20% for adults and under 15% for youths.
Can I use pounds instead?
Yes, as long as both weights use the same unit.
Does terrain matter?
Yes. Slippery, uneven, or high-altitude routes often demand lighter packs to maintain stability and endurance.
Should children carry less?
Yes. Pediatricians usually cap school backpacks at 10–12% of body weight and stress proper strap adjustment.
Additional Information
- Many outdoor educators recommend keeping packs below 20% of body weight for adults and 10–15% for school-aged children.
- Adjust the ratio downward for steep terrain, high altitude, hot weather, or when recovering from injury.
- Pack heavy items close to your spine and mid-back to improve balance and reduce strain on shoulders.
- If you track weight in pounds, convert both body and pack weight to kilograms (or both to pounds) before entering values.
