Many of the thresholds are configurable, and SERP snippet previews are shown to illustrate the warnings.
 Many SEO tools provide characters length as the method to find truncated titles, however that's not the way it works: title length is measured in pixels; it depends on the used font and the way it is rendered by the user agent, so it can vary also depending on the operating system, the browser and its version.
The preview Visual SEO Studio shows is an approximation independent by user's browser; measure might vary of a pixel of two, but being the truncation performed preserving the single words, sometimes the preview emulation can appear different than what seen in the SERP).
Pixel based length is a fact known by many since time, but the first to publicly write about it has probably been Darren Slatten; for sure he is the one who tested and experimented with it most.
 Apparently Google indexes as part of the title only the first 12 words found in the title tag, and the remaining part as normal text.
