Most backpacks will have an area on the straps that you can use to adjust the length of the straps themselves. Pulling more or less strap through the buckle will adjust how long the straps are. Adjust the straps of the backpack until it fits snugly against your back. Avoid leaving too much slack in the straps of the backpack as wearing the backpack too low can hurt your back. Make sure both straps are an equal length to ensure that the weight of your backpack is evenly distributed.

Fragile items should go on top of more durable ones. Some items may have an usual shape or sharp corners. Try to position these so that they don’t poke you in the back.

The hip-belt should fit snugly around your hips and will support much of the weight. Shoulder straps should pull the bag tight against your back but not actually carry much of the weight. Some backpacks will have load-lifting straps. These should relieve the weight from your shoulders and help keep it properly distributed.
