One of the most common things I hear in clinic is some version of: "I don't even know if my posture is bad, I just know something feels off." That's actually a very reasonable thing to not know. You can't see your own alignment from the inside. Your brain adapts to whatever position you're usually in and starts calling it "normal," even when it's pulling your spine out of neutral.

The good news: you don't need a clinic visit to get a real read on your posture. Here are the actual assessments I use, adapted so you can do them at home.

Test 1: The Wall Test (Overall Alignment)

Stand with your back against a wall. Heels, glutes, upper back, and the back of your head should all touch the wall at the same time, with a natural, small gap behind your neck and lower back (not flat, just not exaggerated).

What it tells you:

  • If your head doesn't reach the wall without you forcing it back, you likely have forward head posture, meaning your head sits ahead of your shoulders instead of stacked above them.
  • If your lower back has a large gap (you could fit a full fist behind it), you may have excessive lumbar lordosis (an exaggerated inward curve).
  • If your lower back is flat against the wall with almost no gap, the opposite may be true, a flattened curve, often from prolonged slouched sitting.

Test 2: The Photo Assessment (What I'd Actually Look At Clinically)

This is closer to what I check in an exam room. Have someone take a photo of you standing naturally, don't pose, just stand how you normally would, from the side and from behind.

From the side, look at:

  • Does an imaginary vertical line from your ear pass through the middle of your shoulder, the middle of your hip, and just in front of your ankle bone? In good alignment, it should. If your ear sits noticeably ahead of your shoulder, that's forward head posture, and it's extremely common with desk and phone use.

From behind, look at:

  • Are your shoulders level, or is one higher than the other?
  • Do your shoulder blades sit the same distance from your spine on both sides, or does one wing out more?
  • Is your head tilted to one side?

Small asymmetries are normal, almost nobody is perfectly symmetrical, and that alone isn't a red flag. What matters is whether the asymmetry is significant and whether it's paired with pain, which is worth having a professional look at rather than self-diagnosing.

Test 3: The Shoulder Rotation Check (Muscle Imbalance)

Stand relaxed and look at your hands. If your palms naturally face behind you rather than facing your thighs, that often points to tightness in your pectoralis major and minor (chest muscles) pulling your shoulders into internal rotation, usually paired with weakness in your rhomboids and mid-trapezius (mid-back muscles) that aren't strong enough to counteract that pull. This combination is sometimes called "upper crossed syndrome," and it's one of the most common patterns I see in people who work at a desk or look at a phone for hours daily.

Where Self-Checks Fall Short

These tests give you a snapshot, but posture isn't static. It's how you hold your body across an entire day, and a single wall test or photo can't capture whether you're drifting into poor alignment by hour 3 of your workday. It also can't track whether the exercises you're doing are actually changing anything over weeks and months, because comparing "how I feel today" to "how I felt a month ago" is unreliable. Memory isn't a measurement.

This is the exact problem GoodForm solves. Instead of a one-time wall test, it uses your phone's camera and AI to score your alignment, head position, shoulder level, spinal curve, the same markers covered above, and tracks the score over time so you can see whether your posture is actually improving, not just guess.

GoodForm: Posture Coach is launching soon on the App Store and Google Play. Join the waitlist to be first to try it.
