While your jeans might stretch out in the waistband, they'll frequently shrink in length when you wash them. Luckily, there's an easy way to help them keep their length while returning the rest of their proportions to normal.
Once you've washed your jeans (inside out and in cold water to preserve the color), gently stretch them by grabbing hold of the waistband an pulling the legs lengthwise. Then dry them with low to medium heat. That will also help keep them from shrinking.
