The best results be sure to try and cut your potatoes uniformly. Whether you like thin fries or thicker fries, the key is keeping them all cut to the same size and adjusting the baking time accordingly.
I like to slice the sweet potatoes lengthwise to keep the fries long, and depending on the thickness of the potato, you will want to slice them into 1/2 inch sections, normally getting 3-4 oblong slices.
Then cut again lengthwise, but this is where you can determine how thick you want your fries. Normally, ¼ inch to ½ inch is a good thickness for making this sweet potato fries recipe.
