Way up all the way as far as they can go

I have some that are around 5' tall while others are closer to 10'. Luckily frost is right around the corner or I would need to grow a beanstalk to get to the fruit at the top. My tomatoes are all in full sun. Plants will get taller and lankier though if they get too much shade. Maybe the vigorous sweet potato vines were shading the plant a little too much requiring it to grow taller to get more light.

Here is a link that might be useful: Kim's Garden

The tallest for me has been two SS100 growing to 18ft, pruned to 2 stems. But on average I would say 10ft.

Here in Maine with excellent soil and 8-9 hours of sun, my plants grow to between 3 and 5 feet tall.

Here is western PA I have plants ranging from 6' to 10' tall. The tallest are Marianna's Peace, Cuostralee, Yellow Brandywine and Goose Creek. Ramapo, Crnkovic Yugoslavian and Polish are a few feet shorter. They are still setting and growing fruit. If I get 3 more weeks without frost I should get a pretty good fall harvest.

My Celebrity is about 5' tall but probably 10' wide wallowing all over, strangling a rose bush. A tomato cage is a joke with a bush like this. Having a rose bush inside it makes it tricky to pick tomatoes.

Mine in upstate NY generally go up a 6ft cage, back down again... and then a little.. so 12 feet or so?

My Roma got to about 5' or 1' above the top of it's cage then it collapsed and worked it's way back down. Now it is working it's way out. I'm sure if I had a taller cage it would have grown with it. We have gotten a couple hunderd maters out of it and it keeps on giving. It now has a huge amount of new buds on it since I fertilized it last week.

Not this year, though:

in ground, 8-15+, breed specific'
in Earth 'Tainer, 6'-9'

Note: That's not a knock on earth 'tainers.
They do have their advantages.

Thanks folks for your pictures and comments. I just pruned my Dr. Wyche plants today so that the green tomatoes will have a chance to get ripe before heavy frost kills the plant. Most of the large green tomatoes look like they will get to 12-16 ounces. The smaller green tomatoes will go into relish tomorrow.
