So I'm coming at WPF from a HTML perspective.
I just want to put a TextBox on my Window like this:
<Grid>
<TextBox Name="theName" />
</Grid>
Turns out that the TextBox is then HUGE, covers the whole window. (!)
Ok, that's not what I want, but I don't want to define the EXACT size either since I know Height and Width should be flexible, so I try:
<TextBox Name="theName" Width="Auto" Height="Auto"/>
Same thing. So I try:
<TextBox Name="theName"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"/>
Same thing. So I just hard code the sizes:
<TextBox Name="theName" Width="100" Height="20"/>
Which I know is not a good programming practice in WPF.
So, what how do you tell TextBox to "display default sizes for the font size being used"?

Here's how to create a TextBox in XAML and in code. TextBox textBox = new TextBox(); textBox. Width = 500; textBox. Header = "Notes"; textBox.
The Height and the Width of window is 300 and 400 pixels. The type of Width and Height is a double device-independent unit (1/96th inch). This value can be followed by strings px, in, cm, or pt that a pixel, inch, centimeter, or point respectively. Here is a listing of pixels and other measurements. 1 inch = 96 pixels.
Creating a Line The Line element in XAML creates a line shape. The following code snippet creates a Line by setting its start point (X1, Y1) to (50, 50) and end point (X2, Y2) to (200, 200). That means a line is drawn from point (50, 50) to (200, 200). The code also sets the color of the line to red and width 4.
You can take Bryan's example even a bit further. By specifying a specific alignment that isn't stretch and further constrain the TextBox so that it won't expand beyond a certain size. eg:
<Grid x:Name="LayoutRoot">
<TextBox HorizontalAlignment="Left" VerticalAlignment="Top" Text="TextBox" TextWrapping="Wrap"
MinWidth="15" MinHeight="20" MaxWidth="500" MaxHeight="50"/>
</Grid>
You can take it even further by setting up rows/columns inside the Grid and constraining them in various fashions. As you're coming from an HTML background, think of it like using a table to control layout. Remember that you can also nest other container objects (i.e. StackPanels, WrapPanels, other Grids, etc...).
The challenge with XAML and the WPF/Silverlight controls is that they a very flexible, so you've got to get a handle on all the options and how they affect layout.
Good luck. I'm going through this exact same thing now.

Use a different container. The Grid always streches its child controls to fill the grid cell.
You could use e.g. a stackpanel which only streches its controls in one direction.
