Measuring your shoulder width is a crucial step when it comes to tailoring your wardrobe. A well-fitting garment accentuates your body shape and exudes confidence. Whether you’re shopping for a suit, a shirt, or any other clothing item that requires precise shoulder measurements, knowing how to measure your shoulders accurately is essential. In this comprehensive guide, we’ll walk you through the process step-by-step, ensuring you have the right measurements for a perfect fit.
Firstly, it’s important to understand the difference between shoulder width and chest width. Shoulder width refers to the distance between the outermost points of your shoulders, while chest width measures the circumference of your chest. To measure your shoulder width, stand up straight with your arms relaxed at your sides. Using a flexible measuring tape, place one end at the tip of one shoulder and extend it across the back of your neck to the tip of the other shoulder. Ensure the tape is level and parallel to the ground. Record the measurement in inches or centimeters.
If you don’t have a measuring tape handy, there’s an alternative method you can use. Find a piece of string or a ribbon and drape it across your shoulders in the same way as the measuring tape. Mark the points where the string touches your shoulders with a pencil or pen. Then, use a ruler or measuring tape to determine the distance between the marks. This method may not be as precise as using a measuring tape, but it can provide a good approximation of your shoulder width.
Understanding Shoulder Width Measurement
Measuring shoulder width is crucial for tailoring, posture analysis, and athletic performance. Shoulder width refers to the distance between the acromion processes of the shoulder blades, which are the bony protuberances at the top of the shoulders. Accurately measuring shoulder width enables the determination of optimal clothing sizes, the correction of postural imbalances, and the assessment of body proportions for athletic activities.
Procedure for Measuring Shoulder Width
Equipment
| Required Equipment |
|---|
| Measuring tape |
| Assistant (optional for precise measurement) |
Steps
1. Stand upright with your shoulders relaxed and your back straight. Ensure that your feet are flat on the floor and shoulder-width apart.
2. Position the measuring tape horizontally across the back of your shoulders, placing it just below the acromion processes. The tape should be parallel to the floor.
3. Read the measurement on the tape where it intersects the acromion processes of both shoulders. Ensure that the tape is snug but not constricting.
4. If an assistant is available, ask them to assist in locating the acromion processes and holding the measuring tape in place. This provides a more precise measurement.
5. Record the measurement in inches or centimeters. Repeat the measurement twice to ensure accuracy.

Measuring from the Tips of the Acromion Processes
The acromion processes are bony projections located at the shoulder’s outermost points. Measuring shoulder width from the acromion processes provides an accurate representation of the distance between the shoulders.
Step 1: Position the Person
- Have the person stand up straight with their shoulders in a relaxed position.
- Ensure their arms are hanging comfortably at their sides.
Step 2: Identify the Acromion Processes
- Locate the point where the shoulder blade meets the collarbone.
- Palpate the outer edge of the shoulder blade and follow it towards the front.
- The acromion process will be the most prominent bony protrusion near the shoulder joint.
Step 3: Measure the Distance
- Use a measuring tape to measure the distance between the tips of the acromion processes on both shoulders.
- Hold the tape measure flat against the skin and follow the natural contours of the shoulders.
- Ensure the tape measure is parallel to the ground.
Step 4: Record the Measurement
- Take the recorded measurement and round it to the nearest centimeter or inch.
- Repeat the measurement a few times to ensure an accurate reading.
| Step | Description |
|---|---|
| 1 | Position the person with their shoulders relaxed and arms hanging at their sides. |
| 2 | Identify the acromion processes on each shoulder by palpating the bony projections on the outer edges of the shoulder blades. |
| 3 | Use a measuring tape to measure the distance between the tips of the acromion processes, ensuring the tape measure is flat against the skin and parallel to the ground. |
| 4 | Record the measurement to the nearest centimeter or inch and repeat the measurement a few times to ensure accuracy. |
Measuring from the Acromion to the Deltoid Tuberosity
This method is considered the most accurate for measuring shoulder width. It involves using two landmarks on the shoulder: the acromion process and the deltoid tuberosity.
Locate the acromion process, which is the bony protrusion at the top of the shoulder.
Identify the deltoid tuberosity, which is located on the lateral (outer) side of the shoulder, approximately below the acromion process.
Use a measuring tape to measure the distance between the lateral aspect of one acromion to the corresponding lateral aspect of the other acromion.
Tips for accurate measurement:
- Stand up straight with your shoulders relaxed.
- Keep the measuring tape parallel to the ground.
- Ensure that the tape is pulled taut, but not too tightly.
- Take multiple measurements to ensure accuracy.
Measurement Table:

| Medium | 17-20 |
| Wide | Greater than 20 |
Using a Caliper
A caliper is a specialized tool designed for measuring the distance between two points. It consists of two adjustable arms with measurement markings and a hinge that connects them. Using a caliper to measure shoulder width provides accurate and consistent results.
Steps to Measure Shoulder Width with a Caliper:
- Prepare the caliper: Open the caliper’s arms fully and clean them with a soft cloth if necessary.
- Position yourself: Stand upright with feet shoulder-width apart and arms hanging relaxed by your sides.
- Identify the acromion processes: Feel for the bony bumps on the top of your shoulders, near the base of your neck. These are the acromion processes.
- Place the caliper: Place the tips of the caliper’s arms on the acromion processes of both shoulders. Ensure that the arms are parallel to each other.
- Take the measurement: Close the caliper arms slowly while maintaining parallel alignment. Read the measurement directly from the scale on the caliper.
- Record the results: Note down the measurement in centimeters or inches. Repeat the measurement 2-3 times to ensure accuracy and average the results for a precise shoulder width calculation.
Additional Tips for Accuracy:
- Use a high-quality caliper with precise markings for reliable measurements.
- Stand up straight and avoid slouching, as it can affect the shoulder position and alter the measurement.
- Relax your arms and keep them by your sides to prevent tension or contortions that could distort the results.
- Ensure the caliper arms are parallel to the ground to obtain accurate and consistent readings.
Measuring Shoulder Width
Determining the Average Shoulder Width
The average shoulder width can vary depending on the population and can be influenced by factors such as race, ethnicity, and build. However, a common method for estimating the average shoulder width for a given population is to use the standard deviation (SD) measurement. The SD represents the typical range of variation within a population. For example:
| Population | Average Shoulder Width (cm) | Standard Deviation (cm) |
|---|---|---|
| Adult Males (US) | 44.5 | 3.5 |
| Adult Females (US) | 39.0 | 3.0 |
This table shows that the average shoulder width for adult males in the US is 44.5 cm, with a standard deviation of 3.5 cm. This means that the majority of adult males will have shoulder widths within 44.5 cm ± 3.5 cm, or between 41.0 cm and 48.0 cm. Similarly, the average shoulder width for adult females in the US is 39.0 cm, with a standard deviation of 3.0 cm, giving a range of 36.0 cm to 42.0 cm for most adult females.
Variations in Shoulder Width
Shoulder width is determined by the length of the clavicles (collarbones) and the width of the scapulae (shoulder blades). It can vary significantly between individuals due to factors such as genetics, sex, and body composition.
Sex Differences
On average, men tend to have broader shoulders than women. This is primarily due to the higher levels of testosterone in males, which promotes muscle growth and development.
Body Composition
Individuals with a higher percentage of muscle mass in the shoulders will typically have broader shoulders. This is because muscle tissue is denser and more voluminous than fat tissue.
Posture
Posture can also affect the perception of shoulder width. Slouching or hunching the shoulders can make them appear narrower, while standing up straight can make them look wider.
Measurement Techniques
The most common method for measuring shoulder width is to use a tape measure. The following table provides step-by-step instructions for this method:
| Step | Description |
|---|---|
| 1 | Stand with your arms relaxed at your sides. |
| 2 | Place the end of the tape measure at the tip of one shoulder. |
| 3 | Stretch the tape measure across your back and over the other shoulder. |
| 4 | Read the measurement at the point where the tape measure meets the tip of the other shoulder. |
Factors Affecting Shoulder Width Measurement
Several factors can affect the accuracy of shoulder width measurements, including:
Body Position
The position of the body can significantly impact the measurement. Standing up straight with shoulders relaxed and arms hanging at the sides is recommended for an accurate reading.
Muscle Development
Individuals with developed shoulder muscles will have a wider shoulder width measurement compared to those with less muscle mass.
Bone Structure
The skeletal structure of an individual can also influence shoulder width. Narrow or wide clavicles and shoulder blades contribute to overall shoulder width.
Body Fat
Body fat distribution can affect the appearance of shoulder width. Individuals with more subcutaneous fat around the shoulders may have a wider perceived width.
Measurement Method
The method used for measuring shoulder width can also introduce variations. Using a measuring tape, calipers, or a specialized measuring device can yield different results.
Tape Tension
When using a measuring tape, it’s crucial to apply gentle tension to the tape to avoid inaccurate readings.
Location of Landmarks
Identifying the precise location of the acromion process and the lateral epicondyle of the humerus is essential for accurate measurements.
Equipment Calibration
If using calipers or a measuring device, ensure they are calibrated regularly to maintain accuracy.
Observer Bias
Subjective interpretation of landmarks by the person taking the measurement can introduce bias, especially if multiple measurements are taken.
Variations in Body Proportions
Individuals with different body types and proportions may have varying shoulder widths. For example, ectomorphs tend to have narrower shoulders, while mesomorphs typically have wider ones.
