Limit the word count in the post title

Is there a way to limit the word count of the post title?

I searched over the internet but found nothing.

All I know is, only the content of the post can be limited or excerpted.

simply use this where ever you want to display your title with limited words

<?php echo wp_trim_words( get_the_title(), 5 ); ?>

replace number 5 in above code with whatever number of words you need to display.

Regards.
