Remove the width on your textbox and set HorizontalAlignment="Stretch" on the textbox

You can start from this code:

<TextBox Height="20" TextChanged="TextBox_TextChanged" MinWidth="50" Padding="0" />

And in your code behind

private Size MeasureString(string candidate, TextBox tb)
{
  var formattedText = new FormattedText(
      candidate, CultureInfo.CurrentUICulture, FlowDirection.LeftToRight, new Typeface(tb.FontFamily, tb.FontStyle, tb.FontWeight, tb.FontStretch), tb.FontSize, Brushes.Black);

  return new Size(formattedText.Width, formattedText.Height);
}

private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
{
  if (sender is TextBox)
    ((TextBox)sender).Width = MeasureString(((TextBox)sender).Text, (TextBox)sender).Width;
}
