Note: This list does not include actresses under the age of eighteen. It also does not include celebrities mostly famous for being singers, reality stars, writers, directors, or athletes.
Note 2: Maria de Medeiros is listed on a couple of websites as being 4'6". This does not balance with photos of her standing next to taller people and appearing to be much taller. If her height can be verified, she will be added back to the list.
