Unisex sizes generally correspond to men's sizes. Women often choose one size smaller in unisex clothing or check the measurements in cm directly. Isteshaltbar states as a rule of thumb: unisex S corresponds roughly to typical women's and men's sizes in the middle range; unisex XS corresponds to typical smaller women's and men's sizes. The exact values may vary depending on the brand. The most reliable method for unisex size conversion: measure your chest circumference, waist circumference, and hip circumference in centimeters, then compare them with the brand's size chart. If in doubt, choose the smaller unisex size and check the return policy.

  • Unisex cuts are usually based on men's measurements
  • Women: often choose -1 unisex size
  • Measurements in cm are more reliable than letter sizes
  • Always check the brand-specific size chart

What "Unisex" Means in Clothing and Why Unisex Cuts Fit Differently

Unisex refers to clothing that can be worn by all genders. The cut omits typical gender accents: no waist shaping, no emphasized hip curves, no gender-specific shoulder lines. Typical unisex items are T-shirts, hoodies, sweatshirts, jackets, and sneakers.

The decisive difference from women's fits lies in the cut. Unisex models fall straight and wider because they are oriented toward men's bodies. A women's T-shirt in size S has a narrower chest circumference and narrower shoulder width than a unisex T-shirt in S. For women, this means: The same letter size fits significantly looser in unisex.

  • Unisex Cut: straight, without waist shaping, wide shoulders
  • Women's Cut: fitted, narrower shoulders, emphasized hip area
  • Typical Items: T-shirts, hoodies, sweatshirts, jackets, sneakers
  • Consequence for Women: Unisex tends to fit one size larger than usual

Conversion Chart: Unisex (XS–XXL) to Women's and Men's (EU)

The following table shows indicative conversion values for unisex letter sizes into EU clothing sizes as well as typical body measurements in centimeters. Deviations depending on the brand and cut are normal.

XXL 50–52 60–61 120–126 104–110 118–122

Manufacturer measurement charts such as those from MASCOT provide concrete CM values for chest circumference, waist and hip measurements, as well as inseam and sleeve lengths. These values serve as orientation.

  • In oversized cuts, the actual garment width can be significantly larger than the body measurements

How to Measure Yourself Correctly: Chest Circumference, Waist, Hips, and More

Accurate body measurements are the basis of every size conversion. A measuring tape and a second person to help with measuring are sufficient.

  1. Chest circumference: Place the measuring tape horizontally around the widest part of the chest, let your arms hang loosely. Read the value in cm.
  2. Waist circumference: Measure at the narrowest part of the torso, usually just above the belly button. Do not pull in.
  3. Hip circumference: Measure at the widest part of the hips, about 20 cm below the waist.
  4. Inseam length: Measure from the crotch seam to the ankle, preferably in tight-fitting underwear or leggings.
  5. Sleeve length: Measure from the shoulder joint to the wrist, arm slightly bent.

Pro tip: Always measure in tight-fitting underwear or a thin shirt, never over a thick sweater. Stretch fabrics often give 1–2 cm after washing; for woven fabrics without stretch, preferably orient yourself toward the upper limit of a size range.

Practical Size Tips for Women, Oversized Cuts, and Fit Decisions

Women face a concrete decision with unisex clothing: letter size or measurements? The answer depends on the cut.

  • Rule of thumb for women: Choose one unisex size smaller than the usual women's size. Those who normally wear women's M should choose S in unisex.
  • Chest circumference decides: For broad shoulders or a larger chest circumference, preferably go by the CM measurement rather than the rule of thumb.
  • Oversized cuts: With oversized tops from Beachbodyz, the cut is deliberately kept loose. Women who want a casual fit can choose the normal unisex size; those who prefer a closer-to-body look should choose -1.
  • Material influence: Jersey fabrics with an elastane content give 3–5 cm and forgive size inaccuracies. Canvas or tightly woven cotton without stretch have almost no room.

Three practical cases:

  • Woman with broad shoulders (chest circumference 96 cm): Unisex M fits according to measurements, even if the women's size would be 40.
  • Man with narrow hips (hip circumference 88 cm): Unisex S is sufficient, even if men's 48 is the usual clothing size.
  • Unisex hoodie as a gift: Without measurements, preferably choose one size larger and check the return option.

Quick Cheat: Convert Unisex S/M/L to EU, UK, and US

For international orders, size systems differ from each other. Unisex specifications usually follow the men's scale.

  • Unisex XS: EU 44–46 (Men) / UK 34–36 / US XS
  • Unisex S: EU 46–48 (Men) / UK 36–38 / US S
  • Unisex M: EU 48–50 (Men) / UK 38–40 / US M
  • Unisex L: EU 52–54 (Men) / UK 42–44 / US L
  • Unisex XL: EU 56–58 (Men) / UK 46–48 / US XL

Important: US and UK systems differ considerably in women's sizes compared to men's sizes. Those who order a unisex item from a US shop should calculate with the men's US scale. Clothing size conversion charts show the exact formulas for EU/UK/US as well as inch measurements for the waistband. For international orders, always use the CM measurements as a reference, not just the letter size.

Why Sizes Vary Between Brands and How to Avoid Returns

Two brands, both labeled "Unisex M", can differ by 4–6 cm in chest circumference. Clear size charts with defined measurements reduce returns and improve the purchasing decision significantly.

Causes for deviations:

  • Different measurement standards: Some brands measure the finished garment, others provide body measurements.
  • Fit variants: Slim, Regular, and Oversized have different allowances on the body measurement.
  • Material stretch: Fabrics with an elastane content are cut tighter.
  • Manufacturing tolerances: Industrial production allows deviations of ±1–2 cm.

Checklist when ordering:

  • Compare your own CM measurements with the brand's size chart
  • Read product images and model information (height, size worn)
  • Check return conditions and deadlines before purchase
  • If in doubt, ask customer service for the exact garment measurement

Pro tip: Lay your favorite shirt flat and measure the chest width and length. Compare these values directly with the manufacturer's product measurements. This is more precise than any letter conversion.

How Beachbodyz Unisex Products Fit and Which Size Fits

Beachbodyz produces sustainable streetwear from organic cotton and recycled polyester. The cuts are deliberately kept in an oversized style.

Concrete recommendations:

  • Beachbodyz Oversized T-Shirts: Women tend to choose -1 unisex size. Those who wear women's 38 should choose unisex XS or S.
  • Beachbodyz Hoodies (Regular Oversize): Here the normal unisex size can be chosen according to chest circumference, as the cut already calculates room.

Pro tip: The Beachbodyz size chart on the product page contains the current garment measurements per size. Checking there before purchase saves a return.

Why Precise Size Charts Are More Valuable Than Letters

Letter sizes like S, M, or L are conventions, not standards. Two manufacturers, both printing "M", can deliver garments with a 4 cm difference in chest circumference. This is not an error, but a structural feature of the clothing market.

Those who buy exclusively by letter buy by probability. Those who buy by CM measurements buy by facts. Beachbodyz has therefore invested in a detailed size chart: not as a marketing tool, but because returns cost resources and a wrong fit reduces wearing comfort. Sustainability does not end with the material. It also begins with a garment fitting on the first purchase and being worn for a long time.
