Force `` to scale to text field in the views-ticker module
Views Slideshows has an option for forcing equal heights, failing that I would suggest using a jQuery plugin like equal heights

Views Slideshows:


  Views Slideshow can be used to create a slideshow of any content (not just images) that can appear in a View. Powered by jQuery, it is heavily customizable: you may choose slideshow settings for each View you create.
