First, you will need to decide the height of your cuff. In this example, I have used 1.5" as the final height of the cuff. This is average height for a pant/short cuffed hem.
You will also need to include a seam allowance for the raw edge to be hidden away inside the garment. I added a 4/8" seam allowance. I suggest finishing off the raw edge accordingly to your fabric choice and garment. In this example, I have applied a serged edge.
