What Does Good Posture Look Like? A Side View Reference

What does good posture look like? From the side, the common reference is a line through five points. It runs roughly through the ear, shoulder, hip, knee, and a spot just in front of the ankle. Along that line the spine keeps its natural curves. The neck and low back curve gently inward, and the upper back curves gently outward. The head balances over the shoulders instead of travelling ahead of them. Weight is shared between both feet. That is the picture in most textbooks, and it is a fair starting point. It is also only half the answer. The other half: comfortable posture is a position you can leave easily, in any direction. Nothing to undo first.

What good posture looks like from the side

Picture someone standing side on to a camera in ordinary clothes. Here is what the reference line is pointing at.

Ear over shoulder. The opening of the ear sits close to above the tip of the shoulder. When the head drifts forward, the neck muscles work harder to carry it.

Shoulder over hip. The ribcage rests over the pelvis rather than leaning back behind it or folding forward. The arms hang quietly at the sides.

Hip over knee. The knees stay soft. A locked knee can push the pelvis forward and may ask the low back to do extra work.

Knee over the front of the ankle. The line lands a little in front of the ankle bone. Weight then falls through the middle of the foot rather than onto the heels alone.

The three curves of the spine belong in the picture too. Many teachers compare them to springs that help share the load of the head and trunk. A very flat back or a very rounded one may ask more of the muscles. From the front, the shoulders sit close to level and the weight feels similar in both feet.

Why the line is a reference and not a pose

Bodies are built differently. Chest depth, pelvis tilt, and the size of each curve all vary between healthy people. A line that fits one person may sit a finger's width off in another, with no problem at all. Posture also changes through the day. You stand one way when fresh and another way when tired, and both can be comfortable.

Research backs up this looser view. Large reviews have not found one ideal standing or sitting shape that keeps people free of pain. About 90% of low back pain cases are non specific, meaning no single identifiable cause (WHO, 2023). Posture alone rarely explains pain, and a photo cannot tell you how much effort a position costs. Physiotherapists often put it simply: the best posture is your next one.

What does seem to matter is time spent in one shape without moving. Our Feldypedia entry on what long holding does to the body covers this, whichever shape is being held.

What good sitting posture looks like

Sitting follows the same logic as standing, with the chair taking part of the job. Feet rest on the floor or on a support, so the legs are not hanging. Weight rests on the two sit bones. Those are the bony points you feel when you rock gently on a firm chair. The hips are level with the knees or a little higher. The screen sits near eye height, so the head does not have to drop to read it. The backrest can carry some weight, and the shoulders hang.

Then the part most advice leaves out. Change position often. Perch on the front of the chair for a while, then lean back, then stand for a phone call. A chair you keep leaving is doing its job.

A short self check you can do today

Take a side photo in a doorway, or stand side on to a mirror and glance over. Compare what you see with the five points above. Do not adjust anything yet, just look.

Then put the picture away, because the next part matters more. Standing as you are, ask yourself a few questions. How much effort does it take to stay here? Can you breathe into the belly and the sides of the ribs? Can you turn your head to look over each shoulder without the chest following? Can you shift your weight from foot to foot without bracing first? Comfort and effort tell you things a photo cannot. If the picture looks tidy and standing feels like work, trust the feeling. Our wall exercises for posture lesson uses a wall as gentle feedback for the same kind of noticing.

The Feldenkrais® view: posture as ease of moving anywhere

Moshe Feldenkrais did not like the word posture much, because it suggests something still. He preferred "acture", a word he made up to put action back into the idea. In his view, good posture lets you move in any direction with nothing to prepare first. No shifting of weight, no stiffening, no deep breath before you begin.

That turns the question around. Instead of asking whether you match the line, you ask a different question. How easily could you step, turn, bend or reach from here? The Awareness Through Movement® lessons that I teach work on this mostly lying on the floor. There the floor shows you which parts press and which parts lift, and effort has nowhere to hide. People often stand up afterward and notice the head feels lighter and the feet feel wider. Nobody told them to stand straight. If you want to feel this for yourself, our somatic exercises for beginners lesson is a gentle first step. Our body awareness page explains how Feldy builds on it.

Alongside clinical care and other methods

A few changes deserve a clinician's eyes rather than a mirror. See a doctor or physiotherapist if the rounding of your upper back is increasing over months. The same applies if you have lost height. Back pain together with numbness, tingling or weakness in an arm or leg also needs assessment. Those can point to bone or nerve changes worth looking at. Movement education sits alongside that care and never replaces it.

Other movement methods come at posture from different directions, and each has its own logic. Pilates and strength work build stamina in the trunk muscles, which many people value. Yoga standing poses teach steady contact with the floor and a long spine. The Alexander Technique pays close attention to how the head balances on the neck, often guided by a teacher's hands. Feldenkrais works through small, slow movement variations and the sensing that comes with them. Plenty of people combine two of these, and trying more than one is reasonable.

Does your way of standing look like your mother's? Our explainer on whether posture is genetic sorts the inherited parts from the learned ones. Much of what a photo shows may belong in the second group.

Common Questions about what good posture looks like (FAQ)

What does good posture look like from the side?

A soft line runs roughly through the ear, shoulder, hip, knee and the front of the ankle. The neck and low back curve gently inward, and the upper back curves gently outward. The head rests over the shoulders rather than in front of them. Treat this as a reference point, not a shape to hold still.

What is the best posture for sitting at a desk?

Feet resting on the floor or a support, and weight on the two sit bones. Hips level with the knees or a little above them. Bring the screen up so the top sits near eye height. Let the backrest take some weight. Then change position every twenty or thirty minutes. The best sitting posture is the one you keep leaving.

What should I avoid when working on my posture?

Avoid holding any shape for long periods, including the reference line itself. Avoid pulling the shoulders back and pinning them, lifting the chest and bracing, or tucking the chin hard. Avoid judging yourself by a single photo. Effort you cannot sustain through a day is not a habit yet, so look for ease instead.

Is it safe to change how I stand or sit on my own?

For most people, yes, as long as the changes are small and feel easy. Noticing the weight in your feet or softening your knees carries very little risk. If a new position brings pain, dizziness or tingling, stop and return to what felt comfortable. If you have a spinal condition, ask your clinician what suits you.

How long does it take to change posture habits?

Many people feel a difference in a single attentive session, and at first it fades within hours. A new default, where you stand or sit differently without thinking, takes longer. For many people that takes several weeks to a few months of short, regular practice. Frequent small reminders work better than one long effort.

How is this different from simply holding yourself straight?

Holding yourself straight asks muscles to keep working the whole time, and the shape collapses when your attention moves elsewhere. The approach on this page looks for a position you can leave in any direction without effort. One is a pose, the other is a habit of easy movement. Only the second lasts without being remembered.

When should I see a professional about my posture?

Book a doctor or physiotherapist if your upper back is rounding more over months, or if you have lost height. Do the same for back pain together with numbness, tingling or weakness in an arm or leg. A sudden change in posture without a clear reason also deserves a check. Movement education sits alongside that care.
