Todd Shelton offers sleeve lengths up to 36 inches in one-inch increments. Men over 6'4" typically wear a 35 or 36 inch sleeve. For short sleeve, Todd Shelton offers a standard length of 9 inches. 37 inch long and 10 inch short sleeves are available through Keys to the Factory, a made-to-order order method.
For long sleeve, measure across the shoulders and divide by 2. Add the two measurements together. For example, if your sleeve length measures 27 inches and half your shoulder width is 9 inches, your sleeve length is 36 inches. For short sleeve, simply measure down the sleeve from the top of the shoulder seam to the end of the cuff.
