getBounds for TextFields = getBitmapBounds()
I found out the getBounds()-function gives not exactly the right rectangle with a TextField. It always matches the border bounds, even if the borders are invisible. So I’ve created a more accurate function using getColorBoundsRect().

Hi Mark, getBounds gets inherited from DisplayObject, so it can be expected it returns the border bounds, the methods wasn’t designed for text.
Although your solutions seems to produce a fine result, it is kind of overengineered converting the textfield to a bitmapdata object. Have you tried looking into TextLineMetrics? (http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/text/TextLineMetrics.html)
That in combination with numLines, getLineText and getCharBounds suffices to get al the info you need to find the exact borders 🙂
