Why Shoulder Width Matters in Unisex Clothing
The shoulder measurement is the single most reliable predictor of whether a unisex garment will fit properly, since it does not change with weight fluctuations and directly determines how the sleeves and torso hang (peer-reviewed research).
A garment that fits the shoulders correctly will drape naturally, while one that misses the mark pulls across the upper back or droops down the arm.
A body measurement and a garment measurement are two different things. A garment laid flat measures seam to seam, while a body measurement follows the natural bone structure. Both methods matter, and this guide covers each one so you can compare your numbers directly against any size chart.
Tools You Need to Measure Shoulders Accurately
You only need three items to get a reliable shoulder measurement, none of which are specialized or expensive.
- Flexible tape measure: A soft, cloth or plastic tape that bends around the body. A rigid metal ruler will not work for body measurements.
- A flat surface: For garment measurements, a table or clean floor where the item can lie completely flat without wrinkles.
- A mirror (optional): Useful for checking that the tape stays level across your back without twisting.
The most common issue is using a tape measure that has stretched over time. Compare yours against a ruler before you start, or use a piece of string and measure it afterward against a straight edge.
How to Measure Shoulders on Your Body
Stand naturally with your arms relaxed at your sides and your posture normal.
Step 1: Find the Correct Landmarks
Locate the bony point at the top of each shoulder, where the arm meets the shoulder blade. This landmark is called the acromion process. To find it reliably:
- Raise your arm straight out to the side.
- Feel along the top of your shoulder toward the outer edge, you will hit a distinct bony ridge.
- That ridge is the acromion. Lower your arm and keep your finger on that spot.
A common error is measuring from the curve of the deltoid muscle instead, which places the tape 1-2 inches too far down the arm and adds 2-5 cm to your reading (the CDC).
Step 2: Position the Tape Correctly
Place the end of a flexible tape measure on the edge of one acromion. Run the tape horizontally across the upper back, following the natural curve of your shoulder line, and read where it meets the opposite acromion.
Visual Troubleshooting: What Went Wrong?
Most beginners make one of three errors. Here is how to spot and fix each:
- Tape too high (riding toward the neck): The reading will be 2-4 cm narrower than your true width. You will feel the tape pressing against the base of your neck rather than lying across the flat of your upper back. Fix: lower the tape until it sits on the bony ridge, not the muscle.
- Tape too low (dipping toward the shoulder blades): The reading will be 3-6 cm wider than your true width. The tape will curve downward in the center, following the curve of your upper back instead of staying level. Fix: keep the tape parallel to the floor by checking in a mirror.
- Tape too tight: Compressing the skin pulls the acromion points inward, shaving 1-2 cm off the reading. The tape should sit on the skin without leaving a mark. If you see indentation, loosen it.
The Unisex Body Block Difference
The shoulder-to-chest ratio on a unisex garment differs from a women's cut, which assumes a narrower shoulder relative to the chest (peer-reviewed research). If you have a narrower shoulder frame but a fuller chest, a unisex garment sized by chest alone will pull across the upper back. Measure your shoulders first, then your chest, and compare both numbers against the chart rather than defaulting to your usual letter size.
Write this body measurement down, it does not change with weight fluctuations the way chest or waist measurements do.
How to Measure Shoulders on a Garment
Measuring an existing garment is the more accurate method when you already own a piece that fits well.
Lay the garment flat on a table with the back facing up. Smooth out any wrinkles and align the shoulder seams so they sit naturally, without stretching the fabric.
- Find the point where the shoulder seam meets the collar or neckline.
- Place the end of the tape measure at that point.
- Run the tape straight across the back to the point where the opposite shoulder seam meets the sleeve.
- Record the measurement at that second seam point.
This seam-to-seam measurement is what brands use when they list garment dimensions. For a drop-shoulder piece like DAU-SON's Sunfade Hoodie, the shoulder seam sits lower than your natural shoulder point, so the garment measurement will be wider than your body measurement. That extra width is intentional and creates the relaxed, oversized silhouette.
How to Measure Chest for Unisex Shirts
The chest measurement works alongside the shoulder width to confirm a proper fit. For unisex shirts, the chest determines whether the body feels roomy or restrictive, while the shoulder width controls the overall frame.
To measure your chest, wrap the tape measure around the fullest part of your chest, typically just under the armpits and across the shoulder blades. Keep the tape level all the way around and allow for one finger of space between the tape and your body. Exhale normally and take the reading.
For a garment, lay the shirt flat and measure across the chest from one side seam to the other, about one inch below the armhole. Double that number to get the full chest circumference.
| Measurement | Where to Place Tape | What It Tells You |
|---|---|---|
| Shoulder width (body) | Edge of one acromion to the other | Overall frame and fit |
| Shoulder width (garment) | Shoulder seam to shoulder seam | Cut and intended silhouette |
| Chest (body) | Fullest part of chest | Roominess through the torso |
| Chest (garment) | Side seam to side seam, doubled | Actual garment circumference |
The relationship between your chest and shoulder measurements matters more than either number alone. A wide shoulder with a narrow chest will pull at the buttons, while a wide chest with a narrow shoulder will look boxy.
Measuring for Oversized Fit Clothing
Oversized and boxy fits follow a different logic than standard tailoring. When the goal is a relaxed silhouette, you intentionally size up from your body measurements, but the shoulder width still anchors the fit.
This accounts for the drop shoulder design, where the seam falls past your natural shoulder point. The key is to check that the drop is consistent, a well-executed oversized piece drops the shoulder seam evenly on both sides and maintains the armhole position so the sleeve still hangs correctly.
DAU-SON's loose-fit pieces, like the Snow Wash Hoodie and Vintage Wash Splatter Hoodie, are cut with this drop-shoulder construction in mind. The size guide accounts for the relaxed silhouette, so ordering your usual size delivers the intended oversized look without the garment swallowing you.
Unisex Clothing Size Chart Guide
Unisex size charts typically follow a simple letter progression from XS through XXL, but the actual numbers vary between brands, and more importantly, in how they are derived.
Why Unisex Charts Are Not Gender-Neutral Men's Charts
Most unisex garments are cut with broader shoulders, a longer torso, and a straighter hip line. The 'unisex' adjustment usually narrows the waist slightly and adds hip room, but the shoulder width often remains unchanged from the men's equivalent. This can create a specific problem: a person with a narrower shoulder frame but a fuller chest may find that a unisex medium fits their chest but is too wide on their shoulders, while a unisex small fits their shoulders but pulls across the chest.
If a chart lists both, find the size where your shoulder width falls in the middle of the range, then verify the chest number is within 2-3 inches of your own.
Typical Unisex Size Ranges (Body Measurements)
While brands differ, most unisex charts that list body measurements fall within these ranges for a relaxed fit:
| Size | Shoulder Width (cm) | Chest Circumference (cm) |
|---|---|---|
| XS | 40-42 | 84-89 |
| S | 43-45 | 91-97 |
| M | 46-48 | 99-104 |
| L | 49-51 | 107-112 |
| XL | 52-54 | 114-119 |
| XXL | 55-57 | 122-127 |
These are body measurements, not garment measurements. A garment laid flat will measure 2-4 cm wider at the shoulders because the seam sits slightly past the acromion to allow for movement.
How to Read a Chart That Lists Garment Measurements
Some brands, particularly those selling oversized or boxy fits, list garment measurements instead of body measurements. If a chart says a medium has a 58 cm shoulder width, that is the seam-to-seam distance on the flat garment, not your body measurement. To compare, subtract 4-6 cm for a standard fit or 8-12 cm for a drop-shoulder cut.
The Decision Framework: What to Do When You Fall Between Sizes
- Measure your body shoulder width and chest. Write both down.
- Find the size where your shoulder width fits. This is your anchor size.
- Check the chest for that size. If your chest is within 3 cm of the listed number, that size works.
- If your chest is larger than the listed number: size up one and accept the wider shoulder, the garment will drape loosely rather than pull across the chest.
- If your chest is smaller than the listed number: stay with the shoulder-anchored size. A slightly roomy chest reads as intentional; a tight shoulder never does.
How DAU-SON's Charts Work
DAU-SON's heavyweight hoodies and tees are cut with a relaxed, drop-shoulder construction. The size charts list body measurements, so you can compare your numbers directly. Because the cut is intentionally oversized, ordering your usual size delivers the relaxed silhouette, you do not need to size up.
Common Measuring Mistakes and How to Avoid Them
Several small errors can throw off a shoulder measurement by enough to change your size.
- Measuring at the wrong landmark: The measurement must start and end at the acromion process, not at the curve of the deltoid muscle. Guessing by feel often places the tape too far down the arm.
- Letting the tape dip: The tape should stay level across the upper back. If it curves downward toward the shoulder blades, the reading comes out wider than your actual shoulder width.
- Measuring over bulky clothing: A thick sweater or hoodie adds several centimeters. Measure over a thin t-shirt or bare skin for the most accurate body reading.
- Stretching the garment: When measuring a shirt flat, pulling the fabric taut distorts the seam position. Let the garment lie naturally.
- Ignoring posture: Standing with rolled shoulders or an exaggerated chest changes the distance between the shoulder points. Stand relaxed with your arms down.
For unisex clothing, the relationship between shoulder width and hip width also matters. A garment cut for a broader shoulder and narrower hip can feel restrictive through the lower body, which is why DAU-SON designs its heavyweight pieces with a relaxed fit through the torso rather than a tapered one.
Frequently Asked Questions
How do I measure shoulder width for clothing size?
To measure shoulders for clothing size, find the bony point at the top of each shoulder where the arm meets the shoulder. This is the acromion process. Run a flexible tape measure in a straight horizontal line across your upper back between these two points. Keep the tape level and snug, but not tight. Compare this number to the size chart's shoulder measurement for the garment you want.
What is the difference between shoulder-to-shoulder and chest measurements?
Shoulder-to-shoulder measures the horizontal distance across your upper back between the tips of your shoulders. Chest measurement measures the full circumference of your torso at the fullest part of your chest, typically under the armpits. Both are critical for unisex clothing fit. Shoulder width determines if the seams align properly, while chest circumference ensures the garment isn't too tight or too loose through the body.
How should I measure shoulders for oversized streetwear?
When measuring for oversized fit clothing, take your natural body measurement first. Then, check the garment's flat-lay shoulder measurement. A true oversized fit, like a drop-shoulder hoodie, will have a shoulder seam that falls 2-4 inches past your natural shoulder point. DAU-SON's Sunfade Hoodie, for example, features a drop-shoulder fit that intentionally extends beyond the shoulder for that relaxed streetwear look.
What size is a 22 inch shoulder?
A 22-inch shoulder measurement typically corresponds to a larger unisex size, often XL or XXL depending on the brand. However, unisex sizing varies significantly between manufacturers. Always compare your personal shoulder measurement against the brand's specific size chart. For example, if your shoulder width measures 22 inches, check DAU-SON's size guide to find which size aligns with that number for their heavyweight hoodies and tees.
Finding the right size in unisex streetwear comes down to knowing your numbers. DAU-SON builds every piece with relaxed fits and heavyweight fabrics that are designed to look and feel better over time, and the size guide on each product page is built for easy comparison against your own measurements.
