Size chart

Size guide – find your ideal size
Use our size guide to find the right size for ALBERT KREUZ men’s and women’s underwear. Measure the relevant parts of your body and compare the results with the tables below. The English tables include both UK and US clothing sizes as well as measurements in centimetres and inches.
If your measurement falls between two sizes, we generally recommend choosing the smaller size for a close fit and the larger size for a more relaxed fit.
Men’s undershirts and outerwear
Measure around your chest and compare the result with our table. ALBERT KREUZ men’s undershirts are cut longer than usual so that they stay securely tucked in.

How to measure correctly
Measure directly against the body where possible, standing in a relaxed position.
- 1 Chest: Run the tape measure horizontally around the fullest part of your chest and back. It should pass under your arms and lie close to your body without digging in.
| Size | 3 / XS | 4 / S | 5 / M | 6 / L | 7 / XL | 8 / XXL | 9 / 3XL | 10 / 4XL |
|---|---|---|---|---|---|---|---|---|
| UK / US clothing size | 34 | 36 | 38 | 40 | 42–44 | 46–48 | 50 | 52–54 |
| Chest circumference | 80–86 cm 31.5–33.9 in |
86–96 cm 33.9–37.8 in |
94–102 cm 37.0–40.2 in |
98–109 cm 38.6–42.9 in |
107–117 cm 42.1–46.1 in |
115–125 cm 45.3–49.2 in |
123–133 cm 48.4–52.4 in |
131–141 cm 51.6–55.5 in |
Men’s underwear and pyjamas
To find the ideal size for boxer briefs, briefs or pyjamas, measure your waist where the waistband of your underwear will sit. Choose one size larger if you prefer a looser fit.

How to measure correctly
Stand in a relaxed position and do not pull the tape measure too tightly.
- 1 Waistband: Run the tape measure horizontally around your body at the point where the waistband of your underwear will sit. For our underwear, this is approximately 5 cm / 2 in below the navel.
| Size | 4 / S | 5 / M | 6 / L | 7 / XL | 8 / XXL | 9 / 3XL | 10 / 4XL |
|---|---|---|---|---|---|---|---|
| UK / US clothing size | 36 | 38 | 40 | 42–44 | 46–48 | 50 | 52–54 |
| Waistband circumference | 82–85 cm 32.3–33.5 in |
86–89 cm 33.9–35.0 in |
90–94 cm 35.4–37.0 in |
95–99 cm 37.4–39.0 in |
100–104 cm 39.4–40.9 in |
103–110 cm 40.6–43.3 in |
109–118 cm 42.9–46.5 in |
Measure the waistband circumference at the height where your underwear waistband will sit, approximately 5 cm / 2 in below the navel.
Women’s undershirts, briefs and nightwear
For the ideal size, measure your bust, waist and hips and compare the results with our table. For briefs, the hip measurement is generally sufficient. If your measurement falls between two sizes, choose the smaller size for close-fitting underwear. ALBERT KREUZ women’s undershirts are cut longer than usual.

How to measure correctly
Measure in your underwear where possible and keep the tape measure horizontal.
- 1 Bust: Run the tape measure horizontally around the fullest part of your bust and back. It should pass under your arms and lie close to your body without digging in.
- 2 Waist: Measure around the narrowest part of your torso. Stand relaxed and keep the tape close to your body.
- 3 Hips: Run the tape measure horizontally around the fullest part of your hips and seat. Keep your feet together and parallel if possible.
