My fonts were too large while in Column Layout.
I messed around with the Custom CSS field in Edocman and found a solution.
I added this.
#edocman-category h1.edocman-page-heading
{
margin: 0 0 10px !important;
display: inline;
font-size: large;
}
.edocman-container h1, .edocman-container h2, .edocman-container h3
{
font-size: large;
}
Try different sizes: small, x-small, medium, large, x-large, xx-large
Notice there are settings for 2 different parts. The Heading and the Container Title.
My files page now looks like this. (3 column layout)
I hope this helps others.
