To measure your shoulder-to-hip ratio (SHR), you need two circumference measurements and a simple division: shoulder circumference divided by hip circumference. A ratio above 1.0 means your shoulders are wider than your hips, and most men aiming for an athletic “V-taper” physique target a ratio around 1.4 to 1.6. Here’s exactly how to get accurate numbers.
What You Need
A flexible measuring tape is the only essential tool. A self-locking body tape with a retractable mechanism makes solo measurement much easier, since you can wrap it around yourself, lock it in place, and retract until snug. These typically measure up to 60 inches and show both inches and centimeters. A standard sewing tape works fine if you have a helper. Avoid using a rigid construction tape measure, which won’t conform to your body’s curves.
How to Measure Your Shoulders
There are two ways to measure shoulders, and they give different numbers. The method used for shoulder-to-hip ratio is circumference: wrapping the tape all the way around your shoulders at their widest point. This is different from biacromial breadth, which measures the straight-line distance between your two shoulder bones and requires large calipers. Circumference is what you want here because it captures muscle mass, not just skeletal width.
Stand upright with your arms relaxed at your sides. Have someone wrap the tape around the broadest part of your shoulders and upper chest, passing over the rounded tops of your shoulder muscles (deltoids) and across the upper back. The tape should sit horizontally all the way around. Keep it snug against the skin but not compressing the tissue. If you’re measuring alone, use a locking tape: wrap it around, lock it, then adjust the tension before reading the number. Take the measurement on a normal exhale so your chest isn’t puffed out.
How to Measure Your Hips
Hip circumference is measured at the widest point of your buttocks, not at your hip bones. The NIH defines it as the “maximum extension of the buttocks,” which for most people sits a few inches below the waistband.
Stand with your feet together and your weight evenly distributed on both feet. Wrap the tape around the fullest part of your buttocks. Check that the tape is level on all sides, not angled or dipping in the back. It should be snug but not pulling into the skin. If you’re wearing clothing, wear thin, close-fitting fabric, or measure over bare skin. Bunched-up fabric adds false inches and skews your ratio.
Calculating the Ratio
Divide your shoulder circumference by your hip circumference. Both measurements must use the same unit (both in inches or both in centimeters).
SHR = Shoulder Circumference ÷ Hip Circumference
For example, if your shoulders measure 48 inches and your hips measure 38 inches: 48 ÷ 38 = 1.26. That means your shoulders are 1.26 times the size of your hips. A person with 52-inch shoulders and a 36-inch hip measurement would have an SHR of 1.44.
What the Numbers Mean
There’s no single “ideal” SHR that applies to everyone, but the number does carry both aesthetic and biological significance. In fitness communities, a shoulder-to-waist ratio of around 1.6 is often cited as the target for a pronounced V-taper. The shoulder-to-hip ratio tends to produce a lower number than shoulder-to-waist because hips are typically wider than the waist, so don’t confuse the two. An SHR in the 1.3 to 1.5 range generally reads as a noticeable V-shape.
Research in evolutionary psychology has found that women rate men with a larger SHR as more attractive, more masculine, and better at physical competition. This likely relates to what the ratio signals biologically: broader shoulders relative to the hips correlate with higher levels of hormones linked to testosterone and upper-body muscle development. In studies totaling over 650 women, taller men with larger shoulder-to-hip ratios were consistently rated higher on attractiveness and perceived physical dominance.
For women, the ratio is typically lower. A wider hip measurement relative to shoulders is common and reflects differences in skeletal structure and fat distribution. There’s no health threshold tied to SHR the way there is for waist-to-hip ratio, so this metric is primarily used for fitness tracking and physique goals rather than clinical assessment.
Shoulder-to-Hip vs. Shoulder-to-Waist Ratio
These two ratios are often mixed up online. The shoulder-to-hip ratio compares your shoulders to the widest part of your pelvis and buttocks. The shoulder-to-waist ratio compares your shoulders to your narrowest torso point, usually at or just above the navel. Because the waist is almost always narrower than the hips, the shoulder-to-waist ratio produces a higher number for the same person. If you see someone claiming an SHR of 1.6, they’re likely talking about shoulder-to-waist, not shoulder-to-hip. Make sure you know which ratio a program or calculator is asking for before you compare your numbers to a benchmark.
Common Measurement Mistakes
Small errors in tape placement or tension can shift your ratio noticeably. A difference of just one inch on either measurement changes the ratio by several hundredths, which matters when you’re tracking progress over weeks or months.
- Inconsistent tape tension. Pulling the tape tight on shoulders but leaving it loose on hips (or vice versa) inflates or deflates the ratio. The tape should be snug against the skin on both measurements, with no visible gap and no skin compression.
- Tilted tape. If the tape rides higher in the front than the back, you’re measuring a smaller circumference than the true widest point. Check that the tape is horizontal all the way around, especially at the hips where it can dip behind you without your noticing.
- Measuring after a workout. Blood flow to working muscles temporarily increases their size. Chest and shoulder measurements taken right after an upper-body session can be noticeably larger than baseline. Measure at the same time of day, ideally in the morning before training.
- Wearing thick clothing. Even a hoodie can add half an inch to your shoulder circumference. Measure over bare skin or a single thin layer, and use the same clothing setup each time.
- Holding your breath or flexing. Both artificially expand your chest and shoulders. Stand relaxed, breathe normally, and take the reading on a natural exhale.
How to Track Changes Over Time
If you’re training to build a wider shoulder-to-hip ratio, consistency in how you measure matters more than the absolute number on any given day. Take both measurements once a week at the same time, in the same clothing (or lack of it), using the same tape. Record the raw numbers along with the calculated ratio so you can see whether changes come from shoulder growth, hip changes, or both.
Realistic progress is slow. Adding an inch to your shoulder circumference through muscle growth can take several months of focused training on your deltoids, upper back, and chest. Your ratio will shift in small increments, typically 0.01 to 0.03 per month if you’re gaining upper-body muscle while keeping your hip measurement stable. Tracking the raw circumferences alongside the ratio helps you see progress even when the ratio moves slowly.
