Set the ItemContainerStyle of the ComboBoxItem like this:

 <ComboBox Width="50" Height="40">
        <ComboBox.ItemContainerStyle>
            <Style TargetType="ComboBoxItem">
                <Setter Property="Width" Value="60"/>
            </Style>
        </ComboBox.ItemContainerStyle>
        <ComboBoxItem Content="this is Item One "/>
        <ComboBoxItem Content="this is Item "/>
        <ComboBoxItem Content="this is "/>
        <ComboBoxItem Content="this "/>
    </ComboBox>
