    I found the answer before I submited the question:

    http://mudcu.be/journal/2011/01/html5-typographic-metrics/#bboxUnicode
    http://www.w3schools.com/tags/canvas_measuretext.asp

    var text_width = ctx.measureText("some text").width;

    I used line height for text_height.

    This gives not exact bounding box, but it is fast and usable before text rendering.
