The round-shaped face is known for being almost as wide as it is long and for having a wide cheek area. If this is your face structure, you should go for an arched eyebrow. From the start of the eyebrow, go up until the middle of it, and then down. The lines that the brows create help make your face appear longer. Since the goal is to make your face look less round, you should avoid an eyebrow that is too round or flat.
