How to Pack Your Backpack for Hiking | Load It Right

For the full breakdown, see our best Day Backpack for Hiking guide.

Most people load a backpack wrong, then spend the trail fighting an unstable load. The difference between a comfortable hike and a miserable one often comes down to knowing exactly where each item goes. Whether heading out for hours or days, the same weight-distribution logic applies—once you see it, you will never stuff a pack the same way again.

The Core Rule: Weight Distribution

The heaviest items belong in the middle of the pack, pressed close against your back. This places the load over your hips and spine, where your body carries weight best. The American Hiking Society’s guide to packing a backpack spells out the same principle, and it remains the single most important rule. Working from the bottom up, here is the standard layout:

• Bottom: sleeping bag, sleeping pad, and other light but bulky items you will not need until camp.
• Middle, near the back panel: the real weight — tent, food, stove, and water. Keep these close to your spine, never far back in the pack.
• Top: items you need during the day or as soon as you stop, such as a rain jacket, first-aid kit, snacks, and water treatment.
• Exterior pockets: quick-grab items like a map, flashlight, phone, and water bottle.

This arrangement keeps the center of gravity where it belongs. When heavy gear sits away from your back, the pack pulls backward and forces your shoulders to fight the load all day. Several guides, including REI’s loading advice, make the same warning.

How Heavy Should Your Pack Be?

There is no universal number, but a commonly cited guideline suggests keeping a loaded pack under roughly 20% of your body weight for a multi-day trip. For a day hike, lighter is always better — most casual hikers stay comfortable well under that figure.

Water is the heaviest trick. A liter weighs a kilogram, so plan your water carry for the trail ahead, not just the total trip weight. If buying a pack for day trips, weight matters more than volume — a lighter pack from a solid brand makes the whole hike easier.

The Right Way to Put the Pack On

Loading order matters, but strap adjustment matters just as much. A poorly fitted pack makes even a light load feel twice as heavy, so take thirty seconds to dial it in.

Start with the hip belt — it should sit on your hip bones, not above them. Tighten it first, then snug the shoulder straps so they rest comfortably without digging in. Next, pull the load-lifter straps (the ones angling from the top of the shoulder straps to the pack) to bring the weight in toward your body. Finally, clip and tighten the sternum strap so it keeps the shoulder straps in place without restricting breathing.

MEC’s packing guide highlights a related point: keep strapped-on gear to a minimum. Anything lashed to the outside adds sway with every step, and that movement saps energy fast. If you must attach gear externally, secure it tightly enough that it does not move when you walk.

What to Do About Water and Weather

Rain can ruin a trip faster than any other factor, so protect your gear before you need protection. A pack liner — a simple waterproof sack inside the pack — is the most reliable method, cheaper and more effective than a rain cover. The American Hiking Society also advises keeping stove fuel separate from food and tent materials, and protecting everything from moisture.

On a dry day, a pack liner still costs almost nothing and takes up no real space. The few dollars are the cheapest insurance on the trail.

The most common packing mistakes are all avoidable: putting heavy items too far from your back, burying essentials under gear you will not touch until camp, overloading exterior attachment points, mixing fuel with food, and skipping waterproofing. Avoid those five errors, and every hike starts on the right foot.
