Calculating shoulder width can be helpful when sewing or creating clothing patterns. If you don’t have a tape measure handy, there are a few simple methods you can use to estimate it, such as comparing your height to your arm span or measuring the distance between your shoulders. Once you have an estimated measurement, you can use it to adjust patterns or determine the right size of clothing to buy. Keep in mind that these methods provide an approximation, and the most accurate way to measure your shoulder width is with a tape measure.
To estimate your shoulder width using your height, stand up straight with your feet shoulder-width apart. Relax your shoulders and arms, and measure the distance from the top of your head to the floor. Multiply this number by 0.41 to get an approximate measurement of your shoulder width. For example, if you are 6 feet tall, your estimated shoulder width would be 2.46 feet (6 feet x 0.41).
Taking Measurements Using a Tape Measure
Follow these steps to accurately measure your shoulder width using a tape measure:
-
Stand up straight: Stand in a relaxed and natural posture, with your feet shoulder-width apart.
-
Shoulder Position: Relax your shoulders and let them hang down naturally. Avoid hunching or squaring your shoulders.
-
Locate the Acromion Bones: The acromion bones are located at the outer ends of your collarbone. Gently feel for the bony points at the top of each shoulder.
-
Position the Tape Measure: Place the end of a flexible tape measure on the acromion bone of one shoulder. Wrap the tape around the back of your shoulder, crossing it over your opposite shoulder.
-
Take the Measurement: Hold the tape measure in place and note the measurement where it crosses the acromion bone of your opposite shoulder.
Acromion Bone Identification
The acromion bone is a prominent bony landmark at the end of your clavicle (collarbone). It forms the highest point of your shoulder. To locate your acromion bone, follow these steps:
| Step | Action |
|---|---|
| 1. | Stand up straight with your shoulders relaxed. |
| 2. | Place your thumb on the top of your shoulder. |
| 3. | Move your thumb laterally (outwards) until you feel a bony bump. |
| 4. | This bony bump is your acromion bone. |
Alternating Measurement Technique
This method involves measuring the distance between two alternating points on the shoulders. Follow these steps:
- Stand with your arms at your sides, palms facing your body.
- Locate the acromion process, which is the bony protrusion at the top of each shoulder.
- Measure the distance between the acromion processes on alternating sides of your body. For example, measure from the left acromion to the right acromion, then from the right acromion to the left acromion.
- Repeat this process several times to ensure accuracy.
- Average the measurements to obtain your shoulder width. For example, if you measure 45 cm from left to right and 44 cm from right to left, your shoulder width would be (45+44) / 2 = 44.5 cm.
Here is a table summarizing the steps:
| Step | Description |
|---|---|
| 1 | Stand with your arms at your sides, palms facing your body. |
| 2 | Locate the acromion process, which is the bony protrusion at the top of each shoulder. |
| 3 | Measure the distance between the acromion processes on alternating sides of your body (e.g., left to right then right to left). |
| 4 | Repeat step 3 several times to ensure accuracy. |
| 5 | Average the measurements to obtain your shoulder width. |
Materials Needed
You will need a measuring tape, a level, and a partner.
Instructions
Stand up straight and relax your shoulders. Have your partner place the level across your shoulders, parallel to the floor.
The measuring tape should be placed at the end of your shoulder bones, where your shoulder meets your upper arm.
Have your partner hold the measuring tape straight across your shoulders, parallel to the level. The measuring tape should be snug, but not too tight.
Read the measurement on the measuring tape to the nearest quarter inch.
Accuracy Tips for Shoulder Width Measurement
Proper Posture
It is important to maintain proper posture during the measurement process. This means standing up straight with your shoulders relaxed and your chest lifted. Avoid hunching your shoulders or slouching, as this can affect the accuracy of the measurement.
Level Placement
The level should be placed across your shoulders parallel to the floor. This will help ensure that the measuring tape is parallel to your shoulders and that the measurement is accurate.
Measuring Tape Placement
The measuring tape should be placed at the end of your shoulder bones, where your shoulder meets your upper arm. It should be snug but not too tight. Be sure to hold the measuring tape straight across your shoulders, parallel to the level.
Accurate Measurement
Have your partner hold the measuring tape steady and read the measurement to the nearest quarter inch. It is important to have someone else take the measurement for you, as it can be difficult to measure your own shoulder width accurately.
Using a Clothing Ruler for Broader Shoulders
For shoulders that appear broader, position a clothing ruler perpendicular to the shoulders, with the zero mark aligned with one shoulder’s edge. Extend the ruler across the back, noting the measurement where it reaches the other shoulder’s edge. This value represents the shoulder width for broader shoulders.
Step-by-Step Instructions:
- Stand up straight with your shoulders relaxed and arms at your sides.
- Place the clothing ruler perpendicular to your shoulders, ensuring it’s parallel to the floor.
- Align the zero mark of the ruler with the edge of one shoulder, at the point where the arm meets the shoulder.
- Extend the ruler across your back, keeping it level.
- Note the measurement where the ruler reaches the edge of the other shoulder, which represents your shoulder width for broader shoulders.

Waist-to-Waist Measurement for Symmetry
Step 1: Find Your Waist
Locate the narrowest part of your torso, which is typically around the level of your belly button. This is your natural waistline.
Step 2: Mark the Waistline
Use a measuring tape or a piece of string to mark the waistline on both sides of your body. Make sure the tape or string is parallel to the ground and snugly against your skin.
Step 3: Measure the Distance Between Waistlines
With the measuring tape or string still in place, measure the distance between the two marked waistlines. This measurement represents the width of your waist.
Step 4: Repeat the Measurement
Repeat steps 1-3 to ensure accuracy. If the two measurements are not the same, take the average of the two to determine your waist width.
Step 5: Compare Waist Width to Shoulder Width
Once you have measured your waist width, compare it to your shoulder width. If your shoulder width is significantly wider than your waist width, it may indicate a potential muscle imbalance.
Step 6: Assess Symmetry
If you notice a significant difference in shoulder width compared to waist width, it could be due to:
| Cause | Possible Solutions |
|---|---|
| Muscle imbalance | Strengthening exercises to target underdeveloped shoulder muscles |
| Scoliosis | Professional medical attention and corrective exercises |
| Torticollis | Physical therapy and stretching exercises |
Fine-Tuning Results with a Calipers
For highly precise shoulder width measurements, consider using a body fat caliper. This tool allows you to measure the thickness of the skin and subcutaneous fat at the acromion process, the bony point at the tip of the shoulder. Here’s a step-by-step guide to using a caliper for fine-tuning your measurements:
Step 1: Mark the Acromion Process
Locate the acromion process, the bony prominence at the top of the shoulder. Mark this point with a pen or marker.
Step 2: Open the Calipers
Open the calipers and place the blunt tips on either side of the marked point, perpendicular to the long axis of the body.
Step 3: Measure the Thickness
Close the calipers gently until the tips make firm contact with the skin and underlying tissue. Read the measurement on the dial or scale of the calipers in millimeters.
Step 4: Repeat the Measurement
Take multiple measurements at slightly different locations around the acromion process to ensure accuracy. Average the measurements for a more precise result.
Step 5: Calculate the Corrected Shoulder Width
Subtract the average caliper measurement from the original acromion width measurement. The resulting value represents your corrected shoulder width.
Here’s an example calculation:
| Original acromion width: | 150 mm |
|---|---|
| Average caliper measurement: | 10 mm |
| Corrected shoulder width: | 140 mm |
Uncovering Symmetry Issues with Measured Distances
Measuring shoulder width can reveal discrepancies between the left and right shoulders. By comparing the distances obtained from the acromion processes to the midline, it is possible to assess symmetry and identify any potential imbalances or structural abnormalities.
Calculating Shoulder Width Ratio
To determine shoulder width ratio, follow these steps:
1. Measure the distance from the acromion process of the left shoulder to the midline.
2. Measure the distance from the acromion process of the right shoulder to the midline.
3. Divide the left shoulder measurement by the right shoulder measurement.
The resulting ratio should be close to 1.0, indicating symmetry. Significant deviations from 1.0 may suggest an asymmetry that warrants further investigation.
Troubleshooting Asymmetries
If the shoulder width ratio is not close to 1.0, it is important to consider the following potential causes:
- Scoliosis: This condition can cause a curvature of the spine, leading to uneven shoulder positioning.
- Trauma: Injuries or accidents can result in shoulder displacement or damage to the shoulder joint.
- Muscle imbalances: Overuse or weakness in certain shoulder muscles can cause one shoulder to become higher or lower than the other.
| Shoulder Width Ratio | Possible Asymmetry Issues |
|---|---|
| <1.0 | Right shoulder higher than left shoulder |
| >1.0 | Left shoulder higher than right shoulder |
By carefully measuring shoulder width and comparing the results, it is possible to uncover symmetry issues and take appropriate steps to address any underlying imbalances or structural abnormalities.
Measuring Shoulder Width
Shoulder width is the distance from one shoulder joint to the other. It is an important measurement for clothing, as it determines the fit of tops, jackets, and dresses.
Matching Shoulder Width to Garment Size
To determine your shoulder width, stand up straight with your arms at your sides. Place the end of a measuring tape on the bone at the top of one shoulder and extend it across your back to the bone at the top of the other shoulder. Round the measurement up to the nearest inch or half inch.
Once you have your shoulder width, you can use it to select clothing that fits well. The following table provides guidelines for matching shoulder width to garment size:
| Shoulder Width | Garment Size |
|---|---|
| 15-16 inches | Small |
| 17-18 inches | Medium |
| 19-20 inches | Large |
| 21-22 inches | Extra Large |
| 23-24 inches | 2X Large |
| 25-26 inches | 3X Large |
Keep in mind that these guidelines are approximate. The actual fit of a garment will also depend on the style of the garment, the fabric, and your individual body shape.
