Run this function on page load to resize the text if necessary. The important thing in the css is white-space: nowrap which stops the text from wrapping onto a second line.
Don't forget to give the test span "d" the same font family, style and weight as the real text.

function fittext()
{
    var maxW = 227, maxH = 27, maxSize = 20;
    var c = document.getElementsByClassName("fitin");
    var d = document.createElement("span");
    d.style.fontSize = maxSize + "px";

    for (var i = 0; i < c.length; i++)
    {
        d.innerHTML = c[i].innerHTML;
        document.body.appendChild(d);
        var w = d.offsetWidth;
        var h = d.offsetHeight;
        document.body.removeChild(d);
        var x = w > maxW ? maxW / w : 1;
        var y = h > maxH ? maxH / h : 1;
        var r = Math.min(x, y) * maxSize;
        c[i].style.fontSize = r + "px";
    }
}

fittext();

DIV
{
    width: 227px;
    height: 27px;
    overflow: hidden;
    margin-bottom: 9px;
    background-color: silver;
