What backpack frame size fits my torso?
A pack is sized to your torso length — the distance from the bony C7 vertebra at the base of your neck to the top of your hip bones — not your height. Enter that measurement below and we'll tell you the frame size to look for, and what to do if you land between sizes.
General planning guidance based on common hiking practice and published manufacturer sizing — not a substitute for your own judgment, a proper gear shakedown, or professional instruction on backcountry safety. Always check current conditions before you head out.
