Uneven Shoulders

Quick answer: Uneven shoulders is when one shoulder sits higher, lower or further forward than the other. It’s very common, and most of the time it comes from one-sided habits and from what’s happening lower down, especially at the hips and pelvis. Sometimes it’s a sign of scoliosis, a sideways curve of the spine, which is worth ruling out.

Maybe you’ve noticed your bag always slips off one shoulder, your shirts hang crooked, or one strap of your bra or tank top keeps sliding down. Maybe it shows in photos, or a tailor pointed it out. It’s natural to wonder whether it matters, and what’s pulling one side out of line.

What Are Uneven Shoulders?

Seen from the front or back, your shoulders would ideally sit at roughly the same height and the same distance forward. With uneven shoulders, one is higher or lower, or one rolls forward more than the other. It’s rarely just a shoulder issue: because the shoulders sit on the rib cage, which sits on the spine and pelvis, a difference at the shoulders often reflects a tilt or rotation further down, such as a lateral pelvic tilt.

How Do I Know If I Have Uneven Shoulders?

Stand relaxed in front of a mirror, ideally in a tank top or with bare shoulders so you can see clearly, and let your arms hang naturally. Then check:

1. Height. Does one shoulder sit higher than the other?
2. Rounding. Does one shoulder roll forward more?
3. Arms and hands. Does one arm hang further from your body, or can you see more of the back of one hand?
4. Reach. With your arms at your sides, do your fingertips reach the same height on each thigh?

If you can’t tell in a mirror, ask someone to take a photo of you from the front and the back.

Could Uneven Shoulders Be Scoliosis?

Sometimes. Uneven shoulders are one of the common signs of scoliosis, along with one shoulder blade sticking out more, an uneven waist, and one hip sitting higher. A quick check is to bend forward from the hips with your arms hanging: if one side of your upper back or rib cage sits noticeably higher than the other, see a doctor, who can confirm or rule out scoliosis with an X-ray. For parents, this is especially worth watching during growth spurts. See our scoliosis entry.

What Causes Uneven Shoulders?

• Hand dominance. Most of us reach, carry and lift with one side, and the shoulder on that side often ends up lower or further forward.
• One-sided habits. Carrying a bag on the same shoulder, working a mouse with one hand, driving with one arm forward, or leaning on one elbow at a desk.
• One-sided sports. Tennis, golf, baseball, pickleball and other sports that load one side more. See our guide to golf posture.
• What’s happening below. A higher hip, a rotated pelvis, or uneven hips often shows up as uneven shoulders, because the trunk bends to keep your head level.
• Spinal curves and past injuries. Scoliosis, or an old shoulder, collarbone or rib injury.

A Client Example

One client, a software engineer who spent long days leaning toward his mouse hand, came to us with a noticeably lower right shoulder and recurring shoulder pain. The shoulder was where he felt it, but his assessment showed his hips were uneven too, and his shoulder was compensating for what was happening below. Working on both, his hip and shoulder alignment improved and his shoulder became more comfortable. Individual results vary.

What Are the Symptoms of Uneven Shoulders?

Many people have uneven shoulders and no symptoms. When there are symptoms, they tend to show up on one side. People commonly describe:

• Neck and upper-back tension, often on one side
• Shoulder discomfort when reaching overhead or behind you
• A shoulder blade that sticks out more on one side
• Clothes, bags and straps that never sit evenly

None of these proves uneven shoulders are the cause. See a doctor if you have shoulder weakness, numbness or tingling in your arm, or pain that doesn’t settle.

How Do You Fix Uneven Shoulders?

If you’ve tried hiking up your low shoulder or pulling back your forward one, you’ve probably found it only lasts until you stop thinking about it. That’s normal: the shoulders are often responding to the ribs, spine and hips beneath them.

What tends to help is working from the base up: evening out how the hips and pelvis carry you, restoring movement through the upper back, and balancing how the muscles around each shoulder blade work. Changing one-sided habits helps too. How much the shoulders even out varies from person to person, and uneven shoulders from structural scoliosis behave differently.

Exercises for Uneven Shoulders

Two gentle starting points. Stop anything that causes pain.

1. Sitting Arm Circles

Sit tall on the front of a chair, rolling your hips forward onto your sit bones with a gentle arch in your lower back. Squeeze your shoulder blades back and down, and curl your fingertips into a loose fist. Raise your arms out to the sides at shoulder height and make small circles, about the size of a dinner plate, rolling up and forward. Do 25 to 50, then turn your palms up and do the same number rolling up and back. Notice whether one arm tires or drops sooner than the other.

2. Sitting Elbow Curls

Sit tall in the same position. Curl your fingertips and rest your knuckles on your temples, thumbs pointing down. Bring your elbows together in front of your face, then open them back until they’re in line with your ears. Repeat 20 to 30 times, slowly, keeping your chin level and your lower back gently arched.

Because the hips are so often involved, the exercises in our lateral pelvic tilt guide are a good next step.

Choosing Your Next Step

There’s no single right path. It depends on how you like to work:

• You’d like to start on your own. The checks and exercises above are a sensible place to begin.
• You’d like someone to find what’s driving it. A free 30-minute consultation includes a postural assessment of how you stand and move. We have clinics in Newton, Gloucester, Santa Monica, Beverly Grove and Middletown, RI.
• You’re not near a clinic. Virtual posture therapy brings the same assessment approach to you.

Frequently Asked Questions About Uneven Shoulders

Why are my shoulders uneven?

Most often because of one-sided habits and hand dominance, combined with a tilt or rotation lower down, at the hips and pelvis. Less often, it’s from scoliosis or an old injury.

Is it normal to have one shoulder higher than the other?

A small difference is very common, since nobody is perfectly symmetrical. It’s worth looking into if the difference is noticeable, getting larger, or comes with pain, or if you see other signs of scoliosis.

Can uneven shoulders be fixed?

When they come from habits and how the body is balancing, they often change with consistent work on the whole body, not just the shoulders. Uneven shoulders caused by structural scoliosis won’t change the same way and should be managed with a doctor.

What other names are used for uneven shoulders?

Shoulder asymmetry, an elevated shoulder, a dropped or depressed shoulder, and shoulder imbalance all describe the same pattern. Related terms include rounded shoulders and winged scapula.
