# Localization

Localization (also referred to as "l10n") is the process of adapting a product or content to a specific locale or market.

The default locale of Material UI is English (United States). If you want to use other locales, follow the instructions below.

## Locale text

Use the theme to configure the locale text globally:

```jsx
import { createTheme, ThemeProvider } from '@mui/material/styles';
import { zhCN } from '@mui/material/locale';

const theme = createTheme(
  {
    palette: {
      primary: { main: '#1976d2' },
    },
  },
  zhCN,
);

<ThemeProvider theme={theme}>
  <App />
</ThemeProvider>;
```

### Example

```tsx
import * as React from 'react';
import TablePagination from '@mui/material/TablePagination';
import Autocomplete from '@mui/material/Autocomplete';
import Box from '@mui/material/Box';
import TextField from '@mui/material/TextField';
import { createTheme, ThemeProvider, useTheme } from '@mui/material/styles';
import * as locales from '@mui/material/locale';

type SupportedLocales = keyof typeof locales;

export default function Locales() {
  const [locale, setLocale] = React.useState<SupportedLocales>('zhCN');

  const theme = useTheme();

  const themeWithLocale = React.useMemo(
    () => createTheme(theme, locales[locale]),
    [locale, theme],
  );

  return (
    <Box sx={{ width: '100%' }}>
      <ThemeProvider theme={themeWithLocale}>
        <Autocomplete
          options={Object.keys(locales)}
          getOptionLabel={(key) => `${key.substring(0, 2)}-${key.substring(2, 4)}`}
          style={{ width: 300 }}
          value={locale}
          disableClearable
          onChange={(event: any, newValue: string | null) => {
            setLocale(newValue as SupportedLocales);
          }}
          renderInput={(params) => (
            <TextField {...params} label="Locale" fullWidth />
          )}
        />
        <TablePagination
          count={2000}
          rowsPerPage={10}
          page={1}
          component="div"
          onPageChange={() => {}}
        />
      </ThemeProvider>
    </Box>
  );
}

```

To create your own translation, or to customize the English text, copy this file to your project, make any changes needed and import the locale from there.

Please do consider contributing new translations back to Material UI by opening a pull request.
However, Material UI aims to support the [100 most common](https://en.wikipedia.org/wiki/List_of_languages_by_number_of_native_speakers) [locales](https://www.ethnologue.com/insights/ethnologue200/), we might not accept contributions for locales that are not frequently used, for instance `gl-ES` that has "only" 2.5 million native speakers.

## RTL Support

Right-to-left languages such as Arabic, Persian, Hebrew, Kurdish, and others are supported.
Follow [this guide](/material-ui/customization/right-to-left/) to use them.
