I tested and documented it today. Below you will find the fb.ui feed dialog:

a) the maximum length of the first line, assuming that the line consists of several words. long words are truncated much faster.

b) the total length that is never truncated in the dialog box.

Listing:

  • Field name (name): first line: 50c, total length: 75c.
  • Caption: first line: 50c, total length: 75c.
  • Description: first line: 50c, total length: 512c (maybe more, but hey, which needs more than 512 characters).

Bonus:

  • Image dimensions: 90x90 pixels. It is recommended that you use a 2x3x image for optimal display, but remember that it should be square.

It does not have a maximum length, I think, but after about 205-208 characters it puts 3 dots in the text, and the rest of the text can be viewed by clicking the "see more" link. It does add a “see more” link if there is a long long description.
