Choosing the right hiking backpack size is the most important decision you'll make before hitting the trail. A pack that doesn't fit your torso can cause discomfort, fatigue, and even injury. In this guide, we'll show you how to measure your torso and select a pack that fits like a glove, ensuring your adventures are as enjoyable as possible.

Whether you're a day hiker or planning a multi-day trek, understanding your torso length is the key to finding a backpack that distributes weight properly and moves with your body. We'll walk you through the measurement process, explain how to interpret sizing charts, and share tips for testing the fit in person.

Why Torso Length Matters

Your torso length is the distance from the base of your neck to the top of your hip bones. This measurement determines which backpack size will align the hip belt with your hips and the shoulder straps with your shoulders. A pack that's too long will ride low, causing the hip belt to sit incorrectly and the shoulder straps to dig in. A pack that's too short will sit high, leaving the hip belt floating and forcing the shoulder straps to bear too much weight.

Proper fit ensures that the majority of the pack's weight rests on your hips, which are much stronger than your shoulders. This reduces strain on your back and shoulders, allowing you to hike longer and more comfortably. Investing time in measuring your torso is a small step that pays off big on the trail.

  • A properly fitted backpack can make a heavy load feel significantly lighter.
  • Most backpack manufacturers provide size ranges based on torso length, so accurate measurement is essential.

How to Measure Your Torso for a Backpack

To measure your torso, you'll need a flexible measuring tape and a friend to help. First, find the bony bump at the base of your neck (C7 vertebra). Tilt your head forward to locate it. Place one end of the tape there. Next, find the top of your hip bones (iliac crest). Place your hands on your hips with thumbs pointing back; the top of your hip bones is where your thumbs rest. Have your friend measure the distance between these two points along your spine.

This measurement in inches is your torso length. For example, if the distance is 18 inches, you have a torso length of 18 inches. Repeat the measurement a couple of times to ensure accuracy. Write down the number and keep it handy when shopping for a backpack.

  • Wear the same clothing you'd typically wear on a hike when measuring, as bulky layers can affect the fit.
  • If you're between sizes, choose the smaller pack if you have a narrow waist, or the larger pack if you have a broader waist.

Using Sizing Charts to Choose the Right Pack

Once you have your torso measurement, refer to the manufacturer's sizing chart. Most brands offer small, medium, and large sizes, with specific torso ranges for each. For example, a small might fit 14-17 inches, medium 17-20 inches, and large 20-23 inches. Some packs, like the Mammoth 47.5L, come in specific sizes, so you'll want to match your measurement to the listed range.

Keep in mind that different brands may have slightly different sizing, so always check the chart for the specific pack you're interested in. If you're between sizes, consider the type of hiking you'll be doing. For high-intensity activities where you'll be moving a lot, a snugger fit may be better. For longer trips with heavy loads, a slightly larger pack might offer more room for adjustment.

  • When in doubt, try the pack on with weight in it to see how it feels.
  • Adjustable torso length packs, like the Outdoor Products Morph Backpack, can be a great option if your measurement falls between sizes.

Testing the Fit: What to Look For

When you try on a backpack, loosen all straps and put it on with the hip belt unbuckled. The shoulder straps should wrap smoothly over your shoulders without gaps. Then, buckle the hip belt and tighten it so it sits snugly on your hip bones. The shoulder straps should not be bearing the weight; you should be able to slip a finger between the straps and your shoulders.

Check that the pack doesn't pull backward or sag. If the pack has a load lifter straps (usually located at the top of the shoulder straps), adjust them so they pull the pack closer to your body at a 45-degree angle. Walk around, bend, and reach to ensure the pack moves with you without shifting. If the pack feels balanced and comfortable, you've found the right size.

  • Wear the pack with the weight you plan to carry, as an empty pack won't give you an accurate feel.
  • If you're shopping online, many retailers offer free returns, so you can try the pack at home and exchange if needed.

Choosing the right hiking backpack size is a straightforward process once you know your torso length. By measuring correctly and using sizing charts, you'll find a pack that feels like an extension of your body, making every hike more enjoyable. Remember to prioritize fit over brand or features—a well-fitted pack is the foundation of a great outdoor experience.
