How about Graphics.MeasureString
, with the overload that accepts a string, the font, and the max width? This returns a SizeF
, so you can round round-off the Height
.
using(Graphics g = CreateGraphics()) {
SizeF size = g.MeasureString(text, lbl.Font, 495);
lbl.Height = (int) Math.Ceiling(size.Height);
lbl.Text = text;
}
