How tall and limb length does a "sweet million" tomatoes plant grow?

When fully grown, they tend to grow to a diameter of 1.0 cm and a height of approximately 2.40 metres.

they are indeterminate so they grow till they get sick and die(fungal disease)

I have had Sweet 100 cherry tomato plants that have had branches that reached about ten feet in length and were resting on top of my other tomato plants for further support. I had a yellow pear tomato last year that had two branches that were about fifteen feet long and trained it to the fence that ran along side of it. It all depends on the health of the plant, soil and growing conditions like amount of sun, rain, and watering how big they will grow.

Plant size: 4 to 6 feet tall

Plant type: Indeterminate

While vines don’t tend to get as tall as many other cherry tomato varieties, plants will still need to be staked or caged.
