Are there any limits on no. of characters in Title, description & keywords meta tags?

Hi all…..
Title, Keywords and description meta tags are one of the most important factors for onpage optimization…..but one thing that I always wonder that are there any limits on the no. of allowed characters by different search engines in Title, meta description & meta keywords tag? What if we exceed the no. of characters allowed limit of search engines……
