The cuff of a men's long-sleeve T-shirt at the wrist
Short answer: The cuff of a men's long-sleeve T-shirt should end at the wrist, without riding up the forearm or hanging down over the hand. Check the sleeve length with your arms both straight and bent. Here are tips on the cuff, the length and the washing.
Where the cuff should end
The cuff should sit at the wrist bone, so the sleeve covers the arm but does not hang over the hand. If the sleeve is too short, it rides up when you reach out, and if it is too long, it wrinkles around the wrist. The length depends on your arm length, so it helps to measure from shoulder to wrist.
Check the sleeve length in motion
Stand with your arms down, then lift them forward and up while you watch the sleeves. Bend your elbows and feel whether the sleeve tightens or pulls up. A long-sleeve T-shirt that fits should give enough freedom without shifting much. Look at a bamboo long sleeve T-shirt for men and compare the lengths.
The edge with and without a rib
Some T-shirts have a ribbed cuff at the wrist that holds the sleeve in place, while others have a plain, flat edge. A ribbed cuff can grip and stop the sleeve sliding down, but it can also feel tight if it is too narrow. A flat edge often feels more relaxed, though the sleeve may slide more.
How the sleeve sits under a jumper
Under a jumper or a jacket the sleeve should lie flat, so it does not bunch at the wrist. If the sleeve is too long, it can roll up inside the jumper, and that makes an uncomfortable lump. Choose a length that ends before the cuff of the jumper, so it can follow along without bundling.
Roll the sleeves up and down
Many people roll the sleeves up when it gets warm or when they wash their hands. Choose a fabric that does not crease too much, and roll twice so the edge holds. If the sleeve will not stay up, it may be too thin or too smooth to hold.
Wristwatch and sleeve
If you wear a watch or a bracelet, the sleeve must slide over it without catching. A cuff that is too narrow can tug at the watch, while a slightly looser one gives more freedom. Try putting the T-shirt on and off with the watch on, so you know whether it works.
Washing and shrinking
Viscose from bamboo can shrink if it is washed too hot or dried too hard, and the sleeves can look shorter afterwards. Follow the care label on your own T-shirt and avoid high heat. Take it out while slightly damp and pull the sleeves gently into shape.
Socks and underpants in the same set
When you are choosing the day's clothes anyway, you can think through the whole day. Look at all bamboo socks for men, for example, so you have socks that sit properly. And bamboo underpants for men can give a fit that does not press under the clothes.
Frequently asked questions
How long should the sleeve be on a long-sleeve T-shirt?
The sleeve should end at the wrist bone, without hanging over the hand or riding up when you reach. Measure from the shoulder to the wrist and compare with the size guide.
Is a ribbed cuff better than a flat edge?
It is a matter of taste. A ribbed cuff holds the sleeve in place but can feel tight. A flat edge feels more relaxed, but the sleeve may slide more.
Can the sleeves shrink in the wash?
Viscose can shrink in high heat, so the sleeves may look shorter. Follow the care label, wash gently and avoid hard drying.
