How to override the width of a TextField component with Material UI?

Question

I'm trying to reduce the width of the TextField component :

Here is the render method:

  render() {
    return (
      <div>
          <div>
            <form onSubmit={this.handleSubmit}>
                <TextField
                  hintText="Email"
                  ref="email"
                /><br/>
                <TextField
                  hintText="Password"
                  type="password"
                  ref="password"
                /><br/>
              <button className="btn btn-success" onClick={this.loginCommand}><i className="fa fa-sign-in"/>{' '}Log In</button>
            </form>
          </div>
      }
      </div>
    );
  }
}

I've looked at the parameters, inputStyle etc... – Nicolas Henin Jan 29 '16 at 20:37 — Nicolas Henin, Jan 29 '16 at 20:37

You also can look at fullWidth property to make sure it is set properly.

<TextField
      id="full-width-text-field"
      label="Label"
      placeholder="Placeholder"
      helperText="Full width!"
      margin="normal"
      fullWidth // this may override your custom width
/>

This does not "reduce" the width of the component as OP had asked. This actually will increase the width in certain cases. – Jordan Mar 05 '20 at 23:54

make sure to surround 'true' with curly braces - fullWidth={true} – JGilmartin Mar 06 '21 at 11:49

You could either specify inline style on element like below

  <TextField
        hintText="Email"
        ref="email"
        style = {{width: 100}} //assign the width as your requirement
   />

Or you could do as below.

Declare a styles variable with css properties.

var styles = StyleSheet.create({
    textFld: { width: 100, height: 40}   //assign the width as your requirement
});

Assign it to style in your render code.

<TextField
              hintText="Email"
              ref="email"
              style = {styles.textFld}
            />

Give it try let me know if it works for you. I am new to react js as well.

You could refer to documentations and other similar question on SO for clarity. http://facebook.github.io/react-native/docs/style.html#content

is it working? My text field is working correct if width is 250 px but for smaller width it is not working — Muneem Habib, Nov 24 '16 at 21:16

If you want to make the TextField's width expanded as much as the parent's width (width: 100%):

<TextField label="Full width" fullWidth />

If you want to set the TextField's width to the exact value:

<Box width={350}>
  <TextField label="width: 350px" fullWidth />
</Box>

You can also set the style of the TextField directly if you don't want to add a wrapper component:

V5

<TextField label="width: 350px" sx={{ width: 350 }} />

V4

const useStyles = makeStyles({
  root: {
    width: 350
  }
});

function App() {
  const classes = useStyles();
  return <TextField label="width: 350px" className={classes.root} />;
}

I'd advice you against using inline styles as suggested in other answers since inline styles are harder to override. You should by default use Material-UI styles because it's more flexible and better integrated with Material-UI components. For example, you can cherry-pick the sub-components to override in a larger components, or style psuedo classes and elements, which can't be done with inline style.
