For having an amazingly comfortable backpack, you have to know how to measure your torso length so that the bag can lower your back and neck pains while travelling. And also, don’t forget to measure your hip length. It’s beneficial for buying a perfect backpack.

In this article, I will inform you how to measure torso length, purchase a backpack with the correct measurements, and adjust a torso length backpack.

Let’s begin!

What is torso length?

The human trunk is known as the torso. It’s not your height. It’s an essential measurement. The distance between the top edge of your shoulders or C7 vertebrae to the hip bone’s top crest is the torso length. To get a backpack of the perfect size for yourself, you have to measure your torso length and buy a bag accordingly. It is the one key to find the right backpack for you.

How to measure your torso length?

To measure your torso length, you need a friend to help because it’s the measurement of your back, and you cannot do it individually and a measuring tape.

  • First, tilt your head forward, and you will feel a slight bump at your back where your sloppy shoulders meet your neck. It is called C7, i.e. 7th cervical and called vertebra, and it’s the top of the torso length.
  • With both the index finger in the front and thumb at the back on each side of the body, slowly drag your hands through your ribcage to the top of your hip bones called the iliac crest. Now, tell your partner to draw an imaginary line between both your thumbs. This spot is known as the bottom of your torso length.
  • Now, let your friend measure the distance between the C7 and the imaginary line, i.e. the top and bottom of the torso length.

Wow! You got your torso length.

Measuring hip length will also be helpful.

It’s essential to check your hip belt while purchasing because most of your backpack weight you carry on your hips. So, a good hip bet is essential.

To measure your hip size, you will need a measuring tape. Rap the measuring tape on your upper hip, i.e., the imaginary line area, which you measured while measuring your torso length. Hip belt measurement slightly differs from the pant-size measurement because the hip size is measure from entirely above the pant size.

How to adjust all the straps while wearing a backpack:

Your backpack has many straps which will provide you comfort. We will tie the backpack so that all the weight of the backpack will be on your hips because your leg has the most robust bones that can bear weight.

You will need a mirror to check if the adjustments are done correctly or not before starting to lose all your straps.

Hip belt

While wearing your backpack, you will tie the hip belt across your hips. It should be positioned 2.5cm above the iliac crest. It will help you carry all the shoulder weight because the bones present over there are strong. Do not overtighten the strap; it can hurt you. Ensure the padded portion of the hip belt fits on the top of your hips and try different gestures for proper adjustment and choose the best spot.

Shoulder straps

Don’t make your bag to be too heavy because the straps can only handle the bearable weight. Unnecessary weight can cause back, neck and shoulder problems. Shoulder straps will form a natural shape and will rest completely against your shoulders. It should be rapped 3″ below the top of your shoulder blade. Adjust the loosening and tightening of your straps according to your comfort.

Sternum strap

These straps will come over your chest and an inch below your collarbones, at your heart-height, basically used to keep the shoulder strap properly in place and perfectly positioned on your body.
