How to find the best back length

To find the correct back length for a backpack, follow the measuring steps on this page and then refer to the size chart to see which size backpack is right for you

To find the right size of running vest for you, follow the vest measuring instructions here and then refer to the chart at the bottom to select the best size vest for you.

1. WHAT IS A BACK LENGTH MEASUREMENT?

The back length is defined by the distance between the 7th vertebra and the iliac crest (or top of the pelvis). This is where the two measuring points are located.

2. LOCATING BOTH MEASURING POINTS:

Tilt your head down and the 7th vertebra is the one that arches out below the base of the neck. This is the top measuring point.

Then, place your hand on your hip with your index finger and thumb as illustrated. You will feel the upper edge of the hip bone. This is the lower measuring point.

3. Helpful TOOLS:

Take a belt and wear it horizontally on your hip bone, across the two iliac crests. Try to keep your spine straight as this will also help find the center when measuring.

4. USE A TAPE MEASURE:

Place a tape measure on the 7th vertebra and hold it with one hand. Then let the end drop down. Place your other hand across your hip again with your index finger and thumb splayed, so that your thumb touches the top of the belt.

5. FIND AND HOLD THE MEASURING POINT:

Find the intersection point between the tape measure and the upper edge of the belt in the center of your back. 

Slide your hand along the belt to the tape measure.

Fix the point on the tape measure where the upper edge of the belt meets your thumb.

Then take your index finger and mark this place on the tape as precisely as possible.

6. COMPLETE THE MEASUREMENT PROCESS:

Release the measuring tape at the top while keeping hold of it at the bottom.

7. READ OFF THE MEASUREMENT RESULT:

Keep holding the tape measure at the measuring point, while moving your hand forward. You can now read your back length measurement above your thumb.

Note: The measuring point is above the thumb.

DEUTER SIZE CHART for backpacks

The following table should help you find the perfect fit for your backpack. There are overlaps between the back lengths and body heights in the unisex', men's and women's fit categories. In this case, which model is best will depend on an individual's body shape, such as shoulder width or pelvis. Women should always choose an SL model because of the specific fit features. The fit categories Kids, SL, Unisex and EL also feature backpack models with adjustable back systems. These can be individually adjusted to the person carrying it at the time.

1. stand upright:

Stand upright and tall. This brings your chest forward in the same position as it would be when you’re breathing heavily during exercise. But do not expand your chest too much or take an overly big breath in.

2. pass a tape measure from back to front:

Run a tape measure around your back and pull the two ends under your arms. The tape measure should run along your back just below your shoulder blades, so you can measure your chest circumference at the highest point.

3. measure chest circumference:

Bring the ends of the tape together at the front and at the highest point of the chest to measure the circumference. Please note that this may not necessarily be the nipples area. The measuring tape should not cut into the chest but sit lightly so as not to distort the result. Check that the tape measure is straight and not twisted.

DEUTER SIZE CHART for vests

Backpacks with a vest harness system or running vests needs to create a close fit that wraps around the body for a garment-like fit. Which is why choosing the right size for you is important. Remember also, that the fit will usually be tighter the fuller the pack is. This means that not only the size, but also the intended use should be taken into account when making your choice. These vest-style systems also have adjustable bungee straps that allows them to be adjusted to the individual.
