As per my study and knowledge Title Tag and Meta Description Length for Google, Yahoo, Bing & Ask should be as follows… GOOGLE Page Title: shows 69 characters Page Description: 156 characters long, If your description is better then it can be up to 320 characters long. YAHOO There is no an official number from Yahoo, but as per the analysis Page Title: up to 72 characters long Page Description: up to 161 characters long BING Page Title: shows 65 to 69 characters Page Description: shows 150 to 185 characters ASK Page Title: 69 characters Page Description: around 320 characters Note: all the figure/number of characters are including spaces, special characters like comma "," & Pipe sign "|"
Google takes just 63 characters. But few more characters can be more than 63. But see to it that the length is not less than 63 Characters since you will be wasting the precious space.
Try to keep your keyword in 60 char and Google shows 69 character in title tag. Include all of your keyword in 160 char for description.
60 to 65 characters are the usual way of making a Title Tag. Title Tg must be catchy, at least it has one keyword, and relevant to the content or page.
