Ok so we all (should) know how important page titles (or meta titles) and meta descriptions are. Page titles help you rank for keywords and meta descriptions really help increase your CTR (clickthrough rate) from search engines. Page titles also being your search result title (most of the time) also greatly helps CTR so you wanna get the title and meta description length right, right?
I use this tool by SEOmofo all the time http://www.seomofo.com/snippet-optimizer.html to make sure im not getting anything cut from the snippet. Overblowing meta data is a common issue and id guess close to half of sites have this problem. A cautious note of warning, Google now uses character width rather than count but the tool still holds roughly accurate.
