What are width and height supposed to represent for a sprite? - actionscript-3

Question

I'm working with a Sprite in AS3. Initially, width,height are 0,0 as expected.
After this:
var tf : TextFormat = new TextFormat();
tf.font = "Arial";
tf.size = 48;
tf.bold = true;
text = new TextField();
text.text = "A";
text.x = 30;
text.y = 16;
text.selectable = false;
text.setTextFormat(tf);
addChild(text);
they are 100,100 (even if I shrink the text size).
After this
graphics.beginFill(0xffffff, 1);
graphics.drawRect(0, 0, 99, 99);
graphics.endFill();
graphics.beginFill(color, 1);
graphics.drawRoundRect(6, 6, 84, 84, 8, 8);
graphics.endFill();
They are 130,116. I would expect them to end up at 99,99, what am I missing?
Modification: here's the code from the first answer, but modified to use a single sprite:
var s = new Sprite();
trace("1:", s.width, ", ", s.height) // <-- 0 , 0
var tf : TextFormat = new TextFormat();
tf.font = "Arial";
tf.size = 48;
tf.bold = true;
var text = new TextField();
text.text = "A";
text.x = 30;
text.y = 16;
text.selectable = false;
text.setTextFormat(tf);
s.addChild(text);
trace("2:", s.width, ", ", s.height) //<-- 100, 100
s.graphics.beginFill(0xffffff, 1);
s.graphics.drawRect(0, 0, 99, 99);
s.graphics.endFill();
s.graphics.beginFill(0x000fff, 1);
s.graphics.drawRoundRect(6, 6, 84, 84, 8, 8);
s.graphics.endFill();
trace("3:", s.width, ", ", s.height) //<-- 130,116
Can anyone explain why these 2 behave differently?
Cheers,
Charlie.

Answer 1

I don't know what you're doing elsewhere, but your code is right.
import flash.display.Sprite;
var s = new Sprite();
trace(s.width, ", ", s.height) // <-- 0 , 0
var tf : TextFormat = new TextFormat();
tf.font = "Arial";
tf.size = 48;
tf.bold = true;
var text = new TextField();
text.text = "A";
text.x = 30;
text.y = 16;
text.selectable = false;
text.setTextFormat(tf);
s.addChild(text);
trace(s.width, ", ", s.height) //<-- 100, 100
var s2 = new Sprite();
with(s2) {
graphics.beginFill(0xffffff, 1);
graphics.drawRect(0, 0, 99, 99);
graphics.endFill();
graphics.beginFill(0x000fff, 1);
graphics.drawRoundRect(6, 6, 84, 84, 8, 8);
graphics.endFill();
}
trace(s2.width, ", ", s2.height) //<-- 99, 99
Are the results I get. Is something else in your code scaling objects?

Answer 2

the width and height attribute for a textfield returns the width and height of the textfield boarder, which by default is 100 x 100
try this to see what I'm talking about
text.border = true;
if you want the actual size of the text in the textfield you need
trace(text.textWidth);
trace(text.textHeight);
