The Height of an Average Tomato Plant

Tomato plants vary in height, depending on the variety grown. Determinate tomatoes grow and produce fruit once during the season, typically reaching 3 to 4 feet in height. Indeterminate tomato varieties grow on vines and produce fruit several times during the season. Indeterminate vines average 6 to 12 feet in height.

Average Height For Tomato Plants

Some tomato plants are called determinate because they are programmed to reach a specific height. These varieties reach heights between 3 and 5 feet at maturity. Good varieties of this type include "Brandywine" and "Brandywine Pink," both heirloom varieties, "Roma" and "San Marzano," both paste-tomato producers, "Mountain Belle," which produces cherry tomatoes, and "Mountain Gold," with yellow tomatoes. Tomato plants that continue to grow and become taller throughout the growing season are classified as indeterminate. When grown on supports, these plants need pruning late in the season to control their growth and force plant energy into fruit production. Dwarf tomato varieties are especially suited to growing in containers, for example on a sunny porch or patio.
