I've just cleaned up about 250 titles for a client site. They were WAY too long but sometimes it might just be one character--so with some creative focus you can tighten things up and still get your term or phrases in.
When it comes to software tools, they can only do so much and so you have to take that into consideration. I tend to err on the site of caution and still with the parameters. My goal is between 60-65 characters in titles.
If you are using a CMS (content management system) that also lists the blog name in the title by default, this could put you over as well--so take that into consideration.
