Short bob hairstyles may not always work well with round faces. Chin-length bobs can enhance the roundness of the face, making it seem even rounder and fuller. The best bob haircuts for round faces will generally create straight lines on both sides of the face, adding a vertical line to take the focus off the round shape. Longer bob hairstyles create a lengthier vertical line, and generally work better with round faces than shorter cuts.
One of the best bob haircuts for round faces is a bob that hangs below the chin, and may reach as far as the shoulders. This can help draw the eye down and offer more length to offset the width of the face. A bob of this length will usually look best with straight, thinner styles of hair than wavy or full styles. This keeps the hair from adding extra width. Hair that is straight helps create a more rigid line that seems to pull the face down and makes it appear longer rather than round.
Parting the hair on one side or another is generally better than a part in the middle. Bangs or fringe that cut a line across the forehead should usually be avoided in bob haircuts for round faces, as straight bangs tend to emphasize the shape of the face. Any bangs on the forehead or fringe around the face should usually be kept wispy and uneven to help prevent a straight or curved line.
Even though longer, straight hair tends to work better, bob haircuts for round faces do not all have to look alike. A very short cut can look flattering as long as the line of the cut does not generally add to the round shape of the face. Bobs that end at the chin can also work as long as the hair is layered enough to avoid creating a circle around the face.
Shorter bob haircuts for round faces typically work best with a part that is very much off to one side or another, and nowhere near center. This allows any shorter bangs in front to be swept to the side. As long as the bangs are layered or wispy, this typically gets rid of any line across the forehead. Waves also can work well with shorter bob hairstyles because they create a different shape around the face. Wavy hair on the sides that is pushed back a little will also help take focus off the roundness and provide a slimming, lengthening effect.
