You can check for pelvic tilt at home using a few simple tests that reveal how your pelvis sits relative to the rest of your spine. The most reliable self-assessment is the wall test, which takes about 30 seconds and requires no equipment. A small degree of forward pelvic tilt is normal for most people, so what you’re really looking for is an exaggerated tilt that’s pulling your posture out of alignment and potentially causing pain.
What Pelvic Tilt Actually Means
Your pelvis isn’t meant to sit perfectly level. It naturally angles slightly forward. Pelvic tilt becomes a problem when that angle is excessive in either direction, changing the curve of your lower spine and shifting how your weight distributes through your hips, knees, and feet.
There are two main types. Anterior pelvic tilt is when the front of the pelvis drops down toward your toes more than it should. This creates an exaggerated arch in the lower back. Posterior pelvic tilt is the opposite: the pelvis tips backward, lifting its front edge too far up and flattening the natural curve of the lower back. A lateral tilt, where one hip sits higher than the other, is less commonly discussed but also worth checking for.
The Wall Test
Stand with your back against a flat wall. Your head, upper back, and buttocks should all touch the wall. Now slide one hand into the space between your lower back and the wall.
If you have a neutral pelvis, your hand will fit snugly in that gap with little room to spare, roughly the thickness of your flat palm. If you can easily slide your fist through the gap, your pelvis is likely tilting forward (anterior tilt), pulling your lower back into a deep arch. If there’s almost no gap at all and your lower back presses flat against the wall, your pelvis may be tipping backward (posterior tilt).
This test isn’t precise enough to measure degrees of tilt, but it gives you a reliable first impression of which direction your pelvis favors.
The Mirror Check
Stand in front of a full-length mirror in form-fitting clothes or underwear, facing sideways. Look at the overall shape of your profile from the waist down.
With an anterior tilt, the lower belly tends to push forward even in people who aren’t carrying much abdominal fat. The lower back curves inward noticeably, and the buttocks appear to stick out behind you. Your belt line, if you’re wearing one, will angle downward toward the front.
With a posterior tilt, the profile looks different. The lower back appears flat or even slightly rounded. The buttocks look tucked under, almost like you’re sitting into a slouch while standing. The belt line angles upward toward the front.
For lateral tilt, face the mirror head-on and look at your hip bones. Place your hands on the bony points at the front of each hip (the tops of your pelvis). If one hand sits clearly higher than the other, you may have a lateral tilt. You can also check whether your belt or waistband sits level.
The Lying-Down Hip Flexor Test
Physical therapists use a version of this test (called the Thomas test) to assess whether tight hip flexors are pulling the pelvis forward. You can do a simplified version at home on a firm bed or table.
Sit at the very edge of a sturdy table so your tailbone is right at the end. Lie back slowly while pulling both knees toward your chest. Press your lower back flat against the surface. Then lower one leg toward the floor while keeping the other knee hugged to your chest.
Watch what happens to the lowered leg. If your thigh can rest level with the table surface and your knee bends comfortably past 90 degrees, your hip flexors on that side have normal length. If your thigh stays elevated and won’t drop to table level, the muscles at the front of your hip are short and tight, which commonly drives anterior pelvic tilt. If your knee straightens out instead of staying bent, the muscles that cross both your hip and knee (running down the front of your thigh) are likely contributing.
Test both sides. Tightness on just one side can create a combination of anterior and lateral tilt.
The Bony Landmark Check
Clinicians assess pelvic tilt by comparing two bony points on the pelvis: the front hip bone (the point you feel at the front of your pelvis when you put your hands on your hips) and the bony bump at the back of the pelvis, roughly where your back pockets sit on jeans.
In a neutral pelvis, the front point sits slightly lower than the back point. In anterior tilt, the front point drops significantly lower. In posterior tilt, the front point rises to the same height or higher than the back point. You can try to feel these landmarks on yourself by pressing your fingers into the front and back of your pelvis simultaneously, though it’s easier to have someone else check. This method takes practice and can be tricky to do accurately on your own, especially if you carry more soft tissue around the hips.
Signs You Might Notice Day to Day
Beyond these specific tests, pelvic tilt often announces itself through patterns you may have already noticed but not connected to your pelvis.
Anterior tilt commonly shows up as persistent tightness or aching in the lower back, especially after standing for long periods. Your hip flexors (the crease at the front of your hip) may feel chronically tight, and your hamstrings might feel “short” even though stretching them never seems to help. That hamstring tightness is often the muscles being pulled taut by the tilted pelvis rather than being genuinely inflexible.
Posterior tilt tends to produce a different set of signals. Sitting for long periods may feel more uncomfortable than standing. The lower back can feel stiff and rounded, and you might find it difficult to maintain an arch in your spine during exercises like squats or deadlifts. Some people notice their knees drift forward when they stand because the pelvis tucks under and shifts the center of gravity.
Lateral tilt often creates problems that seem unrelated to the pelvis at first: one-sided lower back pain, a knee that consistently bothers you on one side, or the feeling that one leg is slightly longer than the other. In many cases, the legs are the same length but the tilted pelvis makes one side carry more load.
How Accurate Are Home Tests?
Self-assessment gives you a useful starting point, but it has real limitations. Palpating your own bony landmarks is less reliable than having a trained clinician do it, and even clinical palpation has its limits compared to imaging. The wall test and mirror check are better for identifying obvious tilts than subtle ones.
If your home tests suggest a tilt and you’re also dealing with persistent pain, stiffness, or movement limitations, a physical therapist can provide a more precise assessment. They can distinguish between a structural tilt (caused by differences in bone or joint anatomy) and a functional tilt (caused by muscle imbalances that can be corrected with targeted strengthening and stretching). Most pelvic tilts fall into the functional category, meaning the pelvis is being pulled out of position by tight or weak muscles rather than by a fixed structural issue.
Common Muscle Patterns Behind Each Tilt
Understanding which muscles are involved helps you make sense of your test results. Anterior tilt typically involves tight hip flexors and lower back muscles paired with weak or underactive glutes and abdominals. The tight muscles pull the front of the pelvis down while the weak muscles fail to counterbalance from behind.
Posterior tilt often features the reverse: tight hamstrings and glutes pulling the bottom of the pelvis under, combined with weak or lengthened hip flexors and lower back muscles. People who sit in a slouched position for many hours a day are especially prone to this pattern.
Lateral tilt usually involves one-sided imbalances. A tight muscle on the outer hip of one side, combined with weakness on the opposite side, pulls the pelvis into an uneven position. Habits like always standing with your weight on one leg or carrying a bag on the same shoulder can reinforce this over time.
