Sometimes a textarea field is to small for usage. I add some JavaScript and CSS to resize all textareas a little dynamically: The JS change the size in dependence text-lengthen.

You should store this snippet into a file like this: templates_django/admin/base_site.html

{% block footer %}
<script type="text/javascript">

function textarea_resize() {
    //
    // Resize all textareas
    //
    textareas = document.getElementsByTagName("textarea");
    for (var i = 0; i <= textareas.length-1; i++) {
        try {
            textarea = textareas[i];
            try {
                rows = textarea.firstChild.data.split("\n").length;
                if (rows > 30) {
                    rows = 30;
                }
            } catch(e) {
                rows = 5;
            }
            textarea.rows = rows;
        } catch (e) {
            alert("textarea_resize() error:" + e);
        }
    }

textarea_resize()

At line 16 maybe you mean "if (rows < 30) {"

Thanks, works perfectly !

I'd make a small change (line 16) to have a minimum size concerning the textbox (useful when we are creating a new object) 

 if (rows < 20) {
      rows = 20;
 }
 else if (rows > 30) {
      rows = 30;
 }
