Characters of a word in WPF are placed by it's ideal position by default. This makes larger textst look well equalized and harmonic. But it could lead to a more blurried result for smaller font sizes, because the characters will end up beeing positioned between two pixels. Since WPF 4.0 you can control this by setting the TextOptions.TextFormattingModeproperty on any element.

<!-- Note: You don't need to set to Ideal, since it is the default -->
<TextBlock FontSize="48" TextOptions.TextFormattingMode="Ideal">
    This text is well equalized
</TextBlock>    

<TextBlock FontSize="48" TextOptions.TextFormattingMode="Display">
    This text is displayed sharp 
</TextBlock>

Control anti aliasing

<!-- Default, works well with most digital monitors -->
<TextBlock FontSize="48" TextOptions.TextRenderingMode="Display">
    Rendered with ClearType
</TextBlock>

<!-- For Monitors who do not support ClearType well -->
<TextBlock FontSize="48" TextOptions.TextRenderingMode="Grayscale">
    Grayscaled only
</TextBlock>

<!-- Win Forms Style -->
<TextBlock FontSize="48" TextOptions.TextRenderingMode="Aliased">
    Aliased
</TextBlock>
