I have what is should be a simple question. What is the largest possible TIFF file size?

The largest theoretical size is a few bytes less than 8GB. The image data is addressed with 32bit unsigned offset and size values so one very large image could be split into two strips, each slightly less than 4GB long, and the second startly shortly before the 4GB boundary to ensure 32bit addressability.

In practice 4GB is the limit.

I don't know if that matters here but keep in mind that some operating systems like quite recent Linuxes had a file size limit imposed by the filesystem of 2 GB. (2^31)
