I just redid my 55 gallon tank last month (converting from 100% artificial to 90% real plants
) and have decided to let these go. The grassy part is 13" from top to bottom. Here is a description from Amazon:

They make a perfect background for a 4' tank, and are very easy to work with since you don't need to weigh the base with sand or gravel. You can easily push them down far enough so that the base doesn't show.
I've always thought this person did a great job making use of them:
