A tooth can be broken to the gum line, then with a root canal and a post, a crown can be put on.
Ideally 3 to 4 mm.
Your dentist will need to see the tooth to know if there is enough for a crown
At the very least 2/3 of the tooth structure should be sound tooth structure.
If you have at least 2mm of tooth structure all around the tooth this is called the ferrule That is the minimum, and if you have a root canal in the tooth, the post/core is beneficial for support! sometimes I would recommend a root canal just to be able to place a post.
YOU NEED ABOUT 1/3 TO HAVE A CROWN.
You need to be more specific. Typically you need about 4-6 mm of tooth above crest of bone on X-ray. It translates to 2-3 mm above the gum line. If less than this, then you need a procedure called crown lengthening.
This is a general question with a lot of unknown issues that could preclude placing a crown. Assuming there is no reason for extraction, so long as the tooth has no fracture, decay, that extends below the bone level around the tooth, the tooth can be prepared and a crown placed. If the tooth structure above the bone is too short to hold and maintain a crown, a judgment reserved for the dentist, then a ‘buildup with a restorative material" or a root canal followed with a post and core. Can be used to create a prepared structure to fabricate a crown to.

It's amazing but you don't need a lot of tooth to put a crown on a tooth. if you have about 1 to 2 mm of height all the way around, a crown can be made. 1-2mm doesn't seem like a lot until you magnify it. That's 1 to 2 mm above the gum line.
There has to be about 2-3 millimeters of strong tooth above the gum line to make a crown on it. Sometimes even more is needed depending on the person's bite.
Ideally, 3-4 mm all around is the min. required, but other factors need to be taken into consideration for a good prognosis.
Hope that helps.

It has to be assessed clinically by a dentist
The short answer is it depends on the situation. Ask your dentist to give his/her opinion.
