Luckily, there are plenty of short styles that suit round faces. The main objective is to make the face look more oval than it really is. This is easily achieved by leaving part of that out, which visually shortens the face. An easy trick is to leave one side of your face with some untucked hair. The untucked piece will trick the eye into thinking that your face is narrower than it actually is.
For a round face, a sleek comb-over can be a good option. Adding a side part will hide one of your cheeks, which can make the face look narrower. A deep part also draws focus to the eyes. This style can be combined with a low ponytail to give the face an oval shape. For a more dramatic look, a long-layered style with bangs can look fantastic.
