The height depends upon the type of cactus. There in fact is quite a range in possible cactus heights. For example, a cactus plant may be tall, such as the 40 foot/12 meter giant saguaro cactus [Carnegiea gigantea]. Or it may be small, such as the 2 inch/5 centimeter Ariocarpus fissuratus, which is one of the living rock or fossil cactus plants.
The tallest cactus is the cardon cactus (Pachycereus pringlei)of Mexico which grows to 63 feet or more in height.

Pachycereus weberi, Backebergia militaris, Neobuxbaumia macrocephala, Trichcereus tersheckii and Neocardensia hertzogonia are all of similar size or larger than C. gigantea or P. pringlei.
The giant saguaro cactus [Carnegiea gigantea] can grow to at least 40 feet/2 meters. It can live for at least 100 years. But it won't flower until it's at least 40 years old. Its distinctive white flower is called a bat blossom.
