I'm using styled components something like this

const FormItem = styled(Form.Item)`
     font-size: 16px;
`;

Using Form Item something like this

    <FormItem label="System Pressurized">
    {getFieldDecorator('systemPressurized')(
      <Select defaultValue="" placeholder="Select Type">
        <Option value="Yiminghe">yiminghe</Option>
      </Select>,
    )}
  </FormItem>

I've tried changing font size of AntD but it doesn't seem to workout

There are multiple options to override style elements.

1. You can directly override label elements from global CSS files like:

label { 
   font-size:16px;
}

2. Individual element by adding a script to the label element:

<FormItem 
  label={ <p style={{fontSize:"16px"}}>"System Pressurized"</p> }>
  { getFieldDecorator('systemPressurized')(
    <Select defaultValue="" placeholder="Select Type">
      <Option value="Yiminghe">yiminghe</Option>
    </Select>
   )}
</FormItem>

Please override CSS in your code like

$ .ant-form-item-label>label {
     font-size: 16px;
 }

1. You can directly override the CSS in global.less file like

    & .ant-form-item-label {
       & > label {
        font-size: 16px;
       }
    }
   

2. You can write JSX for this

   <FormItem label = {
    <p style={{fontSize: "16px"}}>System Pressurized</p>}>
   {getFieldDecorator('systemPressurized')(
     <Select defaultValue="" placeholder="Select Type">
       <Option value="Yiminghe">yiminghe</Option>
     </Select>,
   )}
   

add css:

.ant-form-item-label label{
   font-size: 16px;
}

you have two way to style the formItem label

//way one :
//You can override the default css by override below selectors
.form-section .form-group label{
  font-size : 20px
  //YOUR CUSTOM STYLE
}

// way two : 
// You can pass custom component like below : 
  <FormItem label={<p style={YOURCUSTOMSTYLEOBJECT}>System Pressurized</p>}>
    {getFieldDecorator('systemPressurized')(
      <Select defaultValue="" placeholder="Select Type">
        <Option value="Yiminghe">yiminghe</Option>
      </Select>,
    )}
  </FormItem>

then use it like this


<!-- language: lang-js -->

    const formItemLayout =
      formLayout === 'horizontal' ?
      {
        labelCol: {
          span: 4,
          style: {
            "text-align": "left",
            "font-size": "12px"
          }
        },
        wrapperCol: {
          span: 30,
        },
      } :
      null;

<!-- end snippet -->





  



  

//then use it like this
<Form
  {...formItemLayout}
  layout={formLayout}
  form={form}
  initialValues={{
      layout: formLayout,
  }}
>
  <Form.Item
    label={"Full Name"}
    name="username"
    id="name"
    style={{ display: "flex", flexDirection: "column" }}
    defaultValue={name}
    onChange={handleChange()}
    rules={[
        {
            required: true,
            message: 'Please input your name!',
        },
    ]}
    >
    <Input />
  </Form.Item>
</Form>
