除非您指定宽度，否则 WPF tabitem 宽度是自适应的。如果您没有指定宽度，请检查您在定义 TabItem 样式时是否已固定内容控件或容器的宽度。

<TabControl>
            <TabItem Header="long"/>
            <TabItem Header="longlonglonglong"/>
</TabControl>

初始控件模板

<ControlTemplate TargetType="{x:Type TabItem}">
     <Grid x:Name="templateRoot" SnapsToDevicePixels="true">
         <Border x:Name="mainBorder" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1" Margin="0">
             <Border x:Name="innerBorder" Background="{StaticResource TabItem.Selected.Background}" BorderBrush="{StaticResource TabItem.Selected.Border}" BorderThickness="1" Margin="-1" Opacity="0"/>
         </Border>
         <ContentPresenter x:Name="contentPresenter" ContentSource="Header" Focusable="False" HorizontalAlignment="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
      </Grid>
</ControlTemplate>
