Length of Title and description tag in header

[rjjj111]

I am planning on updating my title tags and add a better description tag in the meta data.

any suggestions as to how long for each? any reason backing those ideas up?

These look like some pretty great guides to creating meta tags and title tags. Every search engine seems to do things a little differently, but these should help you out.

I make short titles for my sites with my strongest keywords. It is working for me.

Keep the title tag up to 70 characters including spaces, and if possible the keywords to be within the first 64 characters including spaces.

Keep the description up to 200 characters including spaces. If possible not longer than 151 characters including spaces.

The optimil average title tag length are 7-8 words.
