Size guide – find the right size easily
Our size guide helps you quickly find the right size for ALBERT KREUZ men’s and women’s underwear. Simply measure the relevant body measurements and compare them with the tables below.
If your measurement falls between two sizes, the general rule is: choose the smaller size for a close fit and the larger size for a more comfortable fit.
Men’s undershirts and men’s T-shirts
Measure your chest and compare the result with our size chart. ALBERT KREUZ men’s undershirts are cut longer than usual so they stay tucked in.

Men’s underwear and pajamas
To find the right size for boxer briefs, briefs or pajamas, measure your waist where you want the waistband to sit. If you prefer a looser fit, choose one size larger.

Women’s undershirts and women’s briefs
To find the right size, measure your bust, waist and hips, then compare the values with our size chart. For briefs, the hip measurement is usually the most important. If your measurement falls between two sizes, choose the smaller size for close-fitting underwear. ALBERT KREUZ women’s undershirts are also cut longer than usual.

How to measure correctly
For the most accurate result, use a soft measuring tape and measure directly on the body without pulling the tape too tight. Measure the chest or bust at the fullest part. Measure the waist where you usually wear the waistband of your underwear. Measure the hips at the widest part.
If you are between two sizes, your personal preference helps you decide: choose a closer fit for a discreet look under clothing, or a slightly looser fit for more comfort.
