With inspiration from @bnguyen82 i came up with something that works all the way.

public static void ScaleLabel(Label label, float stepSize = 0.5f)
{
    //decrease font size if text is wider or higher than label
    while (lblTextSize() is Size s && s.Width > label.Width || s.Height > label.Height)
    {
        label.Font = new Font(label.Font.FontFamily, label.Font.Size - stepSize, label.Font.Style);
    }

    //increase font size if label width is bigger than text size
    while (label.Width > lblTextSize().Width)
    {
        var font = new Font(label.Font.FontFamily, label.Font.Size + stepSize, label.Font.Style);
        var nextSize = TextRenderer.MeasureText(label.Text, font);

        //dont make text width or hight bigger than label
        if (nextSize.Width > label.Width || nextSize.Height > label.Height)
            break;

        label.Font = font;
    }

    Size lblTextSize() => TextRenderer.MeasureText(label.Text,
        new Font(label.Font.FontFamily, label.Font.Size, label.Font.Style));
}

PS: In order for this to work the label needs to have AutoSize = false and either to be docked or anchored.
