Size in men's underpants and how to measure yourself
Short answer: Measure your waist around the body where your trousers sit and compare it with the size chart rather than taking the size you usually wear. That is the surest way to underpants that sit flat without cutting in or sliding.
Measure your waist correctly
Use a soft tape measure and place it around the body where you normally wear your trousers. Stand relaxed and do not pull your stomach in. The tape should lie flat and level without squeezing, and you should be able to fit a finger under it. Write the measurement down and compare it with the brand's size chart.
The chart is your starting point
The size chart translates your measurement into a size, and it is more reliable than habit. See the range under bamboo underpants for men, and find the chart that belongs to the model you want to buy. If you are between two sizes, read the next section on what matters most to you.
Between two sizes
If your measurement falls between two sizes, think about what bothers you most. If you want a calm, close cut, the smaller can fit. If you prefer room to move, take the larger. Elastic and cut vary from brand to brand, so you cannot always use the same size with different brands.
How the right underpants sit
The waistband lies flat without cutting in or leaving clear marks, and the legs neither squeeze nor slide up. The fabric does not bunch in the crotch, and you do not think about the underpants along the way. If they fit properly you can forget them, and that is the simplest test over a whole day.
Signs the size is too small
The waistband leaves marks, the legs squeeze and creep up, and the fabric is pulled thin over the thigh. That can become uncomfortable during the day, and the elastic wears faster. Going up a size usually helps, but always check the measurement and the chart before you decide.
Signs the size is too large
The waistband slides or rolls, the fabric bunches in the crotch, and the legs sit loose. A size that is too large can look like a comfortable solution, but it is often more irritating than a fitting one, because the fabric does not lie calmly. Go down a size if your measurement says you should.
When your body or weight changes
Your body changes over time, and so does your measurement. Measure again now and then, especially if you switch brand or cut. It takes a few minutes and saves you a pair that does not fit. Be aware that clothes can fit differently even when the measurement is the same.
Try before you fill the drawer
Buy one pair in the size the chart points to and wear it for a whole day. If it fits, you can order more in the same size. You can also look at bamboo inner shorts and bamboo T-shirts for men if you want to try more pieces with the same care and take measurements for the rest of your clothes.

Where do I measure my waist for underpants
Measure around the body where your trousers normally sit, with a soft tape measure. Stand relaxed and compare the measurement with the size chart for the model you want to buy.

It depends on what bothers you most. For a calm cut the smaller may fit, otherwise the larger. Try one pair first before you buy several.
