# Converting from `Typography` to `Text`

The `Typography` component has been deprecated in favor of the `Text` component. You can contribute by submitting a PR against [Replace deprecated Typography with Text component](https://github.com/MetaMask/metamask-extension/issues/17670) on GitHub. Below are code examples converting from `Typography` to `Text`.

### Variant

Table below is the 1:1 mapping of `TypographyVariant` to `TextVariant` and the html element that needs to be rendered.

The new `Text` component does not have matching default elements for `TypographyVariant.H5`, `TypographyVariant.H6`, `TypographyVariant.H7` or `TypographyVariant.H8` or `TypographyVariant.H9` variant.

If you need to use these variants, please use the `as` prop to render the correct html element.

| TypographyVariant                                          | Typography Tag | TextVariant           | Text Default Tag |

| [TypographyVariant.H2](#typographyvarianth2)               | h2             | TextVariant.headingLg | h2               |
| [TypographyVariant.H3](#typographyvarianth3)               | h3             | TextVariant.headingMd | h3               |
