Things You Need to Measure Shoulders
Gather these measuring tools before you take your shoulder measurements.
- Measuring tape: You can purchase a standard flexible measuring tape from any craft, sewing, or hardware store.
- Someone to help (optional): While it’s possible to measure your shoulders on your own, it can be challenging to get accurate measurements without someone to assist you. If possible, ask a friend or family member to help.
- A well-fitting T-shirt: If you would rather measure shoulders by yourself, have a T-shirt that fits well handy.
Measuring Shoulders With Someone’s Help
The easiest way to measure shoulder width is with the help of someone else. Here’s how to do it:
Step 1: Stand up straight

Before you begin, stand up straight with your arms relaxed at your sides. Make sure you’re standing in a natural posture with your shoulders level.
Step 2: Locate the acromion bone

Ask your helper to locate the acromion bone, which is the bony protrusion at the top of each shoulder. It’s easy to locate. Simply have your helper run their finger along the top of your shoulder until they feel a small bump.
Step 3: Measure the distance between both shoulders

Once your helper has located the acromion bones, they should stretch the measuring tape across your back, from one acromion bone to the other. Make sure the measuring tape is straight and level, and that it’s touching both acromion bones equally.
Step 4: Record the measurement in centimeters or inches
The final step is to record the measurement in either inches or centimeters, depending on your preference or the size chart you plan to use. Make sure to write it down accurately so you can use it later to find clothes that fit well.
Measuring Your Shoulders by Yourself
If you don’t have someone to help, don’t worry. You can still measure your shoulders with just a T-shirt and a measuring tape. Here’s how:
Step 1: Grab a T-shirt that fits well
Start by finding a T-shirt that fits you well and that you feel comfortable in. This will be used as a guide for measuring your shoulders accurately.
Step 2: Lay the T-shirt flat on a table
Now, lay the T-shirt flat on a table or on the floor. Spread it out evenly and ensure there are no wrinkles that could skew the measurements. You’re ready to take the shoulder measurement now.
Step 3: Measure between shoulder seams
Take your tape measure and measure from one shoulder seam to the other. Do so across the back of the T-shirt so you get proper measurements.
Step 4: Record the measurement
Note the measurement in centimeters or inches, depending on what size chart you’re comparing the measurements with.
Tips for Accurate Shoulder Measurements

To ensure that you get the most accurate shoulder measurements possible, follow these tips:
Stand up straight
Make sure you’re standing up straight with good posture when taking your measurements. Slouching or hunching over can affect the accuracy of your measurements.
Wear fitted clothing
If you have someone to help with measuring your shoulders, wear fitted clothing that will help them find the right points to start and end the measurement.
Consider your body shape
If you have a broader-than-average shoulder width, consider sizing up a little when purchasing clothes online.
Keep the tape level
The measuring tape should run straight across your back from one shoulder point to the other. If the tape dips or sits at an angle, the measurement may not be accurate.
Don’t pull the tape too tight
The tape should rest naturally against the body or shirt. Pulling too tightly can make the measurement smaller than it should be.
Consider your body shape
If you have a broader-than-average shoulder width, consider sizing up a little when purchasing clothes online.
Take note of shoulder measurements for different types of clothing
Jackets and suits can have padded shoulders or thicker materials that may require you to size up when measuring shoulders. So consider the type of clothing you plan to purchase when recording the measurements.
Common Mistakes When Measuring Shoulder Width
Learning how to measure shoulder width is simple, but small mistakes can affect the final number. Avoid these common issues:
- Measuring too close to the neck: Shoulder width should be measured from shoulder point to shoulder point, not from the neckline.
- Measuring too far down the arm: The measurement should begin and end at the top of each shoulder, where the shoulder naturally ends.
- Using a loose or stretched-out T-shirt: If you measure a shirt by yourself, choose one that fits well and still holds its shape.
- Ignoring the full size chart: Shoulder width is important, but it should be compared with other measurements like chest, waist, sleeve length, and torso length when available.
Why Is Shoulder Measurement Important?
Accurate shoulder measurements are important for a variety of reasons when shopping online.
- Sizing clothes, particularly for tailored items. Tailored garments require precise measurements to ensure a proper fit.
