Todd Shelton offers sleeve lengths starting at 32 inches and increasing in one-inch increments. Men under 5'8" typically wear a 32 or 33 inch sleeve. For short sleeve, Todd Shelton offers a standard length of 9 inches. 8 inch short and 31 inch long sleeves are available in 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 23 inches and half your shoulder width is 9 inches, your sleeve length is 32 inches. For short sleeve, simply measure down the sleeve from the top of the shoulder seam to the end of the cuff.
