How to be assured that our written title’s end characters are not going to be omitted by Google?

Titles are sometimes ignored-replaced by Google for issues else than the lenght of the title it self, sometimes the relevancy and other times just because Google algorithm thinks its not suitable.

I guess the best answer here is, write titles for your users, not for the search engines :), if your users are happy, Google will get infected by this happiness, trust me on this.

I think there is no way other then write your titles within55-60 char limit better less then55 char or wide enough to fit within512-pixel display

If there is really any trick then offcourse i like to learn :) 

Here are my Tips:

Step1:

Open an MS word file and wright down your title here, or just copy paste it here from any other document you have used to write it.

Step2:

Go to Google search page and search any topic. From the returned search results pages copy the title of any such result which is showing on the full width (a title which is acquiring maximum space given by Google for title area), now paste it in the same MS word document. 

Step3:

You will notice that your pasted title (from Google) is using the same font-size, font-family and other font styling used by Google search results. Just highlight this title and press the format button from home tab (button showing a paint brush image). Now highlight your written title line.

Step4:

Your written title will now showing the similar format of Google search results. If your title is showing in bold then you can simply unclick bold option. (It happens when your copied format is using bold text at the beginning of line; while copying the format your whole line becomes bold)

Step5:

Compare your title width with the width of your copied title from Google search results.  

Extra Tips:

1-     Don't use excessive capitalization because capital words use more space. In short, only capitalize the proper nouns and leave the common nouns small.

2-     Try to avoid stop words or words with short length to reduce space count.
