Choosing your boxer brief size from your waist measurement
Oct 07, 2026
Short answer: Measure your waist where the waistband of the boxer briefs will sit, and compare the number with the size chart. If you fall between two sizes, choose by how close you like your underwear to sit. Hold your number up against the chart before you choose bamboo boxer briefs.
Measure the waist correctly
Stand with a relaxed stomach and put a soft tape around your body where the waistband will sit. The tape should run level and not be tight. Read the number and write it down. Measure directly on the skin or over thin clothing, so the number does not come out too large.
Where the waistband sits on you
The waistband can sit at the waist, on the hip or somewhere between, depending on the model. So measure where you want the waistband to be. Then you get a number that fits your own habit. If you are unsure, measure in two places and see how big the difference is.
Use the size chart
Find your number in the size chart for bamboo boxer briefs and choose the size where it falls. The chart can vary between models, so always use the one that belongs to the exact model you are looking at. Size labels such as M or L are not the same everywhere.
When you fall between two sizes
If you fall between two sizes, think about how you want it. Choose the smaller if you want the underwear close, and the larger if you prefer it looser. Do not choose too small in the hope that the fabric will give, because the waistband can then cut in.
Leg length and cut
Boxer briefs come with different leg lengths and in different cuts. The leg should end where it does not press, and not ride up when you move. Think about what you wear on top, and choose the length by that. Size is only part of the fit.
Try them on and feel
Put the boxer briefs on and walk around a little. Sit down and bend over. The waistband must not cut in, and the legs must not press. A good pair is barely noticeable. If they do not fit, try the next size. It is easier to adjust now than after several washes.
What changes over time
The fabric and the elastic change a little with wear and washing. Viscose can give a little, and the elastic can become softer. Wash at a low temperature and avoid the tumble dryer so the fit lasts longer. Measure again if you have gained or lost weight.
The same method for the rest of your clothes
The same thinking works for other clothes. Use your measurement and the size chart for bamboo underwear for men and for bamboo T-shirts for men. That makes it easier to get it right every time, and you spend less effort on exchanges.
