## Width

Use the `width` or `w` property to set the width of an element.

```jsx
// hardcoded values
<Box width="64px" />
<Box w="4rem" />

// token values
<Box width="5" />
<Box w="5" />
```

### Fractional width

Use can set fractional widths using the `width` or `w` property.

Values can be within the following ranges:

- Thirds: `1/3` to `2/3`
- Fourths: `1/4` to `3/4`
- Fifths: `1/5` to `4/5`
- Sixths: `1/6` to `5/6`
- Twelfths: `1/12` to `11/12`

```jsx
// half width
<Flex>
  <Box width="1/2" />
  <Box width="1/2" />
</Flex>

// thirds
<Flex>
  <Box width="1/3" />
  <Box width="2/3" />
</Flex>

// fourths
<Flex>
  <Box width="1/4" />
  <Box width="3/4" />
</Flex>

// fifths
<Flex>
  <Box width="1/5" />
  <Box width="4/5" />
</Flex>

// sixths
<Flex>
  <Box width="1/6" />
  <Box width="5/6" />
</Flex>

// twelfths
<Flex>
  <Box width="3/12" />
  <Box width="9/12" />
</Flex>
```

### Viewport width

Use the modern viewport width values `dvw`, `svw`, `lvw`.

> `dvw` maps to `100dvw`, `svw` maps to `100svw`, `lvw` maps to `100lvw`.

```jsx
<Box width="dvw" />
<Box w="dvw" /> // shorthand
```

| Prop         | CSS Property | Token Category |
| ------------ | ------------ | -------------- |
| `w`, `width` | `width`      | `sizes`        |

## Max width

Use the `maxWidth` or `maxW` property to set the maximum width of an element.

```jsx
// hardcoded values
<Box maxWidth="640px" />
<Box maxW="4rem" /> // shorthand

// token values
<Box maxWidth="xl" />
<Box maxW="2xl" /> // shorthand
```

| Prop               | CSS Property | Token Category |
| ------------------ | ------------ | -------------- |
| `maxW`, `maxWidth` | `max-width`  | `sizes`        |

## Min width

Use the `minWidth` or `minW` property to set the minimum width of an element.

```jsx
// hardcoded values
<Box minWidth="64px" />
<Box minW="4rem" /> // shorthand

// token values
<Box minWidth="8" />
<Box minW="10" /> // shorthand
```

| Prop               | CSS Property | Token Category |
| ------------------ | ------------ | -------------- |
| `w`, `width`       | `width`      | `sizing`       |
| `maxW`, `maxWidth` | `max-width`  | `sizing`       |
| `minW`, `minWidth` | `min-width`  | `sizing`       |

## Height

Use the `height` or `h` property to set the height of an element.

```jsx
// hardcoded values
<Box height="40px" />
<Box h="0.4rem" /> // shorthand

// token values
<Box height="5" />
<Box h="5" /> // shorthand
```

### Fractional height

Use can set fractional heights using the `height` or `h` property.

Values can be within the following ranges:

- Thirds: `1/3` to `2/3`
- Fourths: `1/4` to `3/4`
- Fifths: `1/5` to `4/5`
- Sixths: `1/6` to `5/6`

```jsx
<Box height="1/2" />
<Box h="1/2" /> // shorthand
```

### Relative heights

Use the modern relative height values `dvh`, `svh`, `lvh`.

> `dvh` maps to `100dvh`, `svh` maps to `100svh`, `lvh` maps to `100lvh`.

```jsx
<Box height="dvh" />
<Box h="dvh" /> // shorthand
```

## Max height

Use the `maxHeight` or `maxH` property to set the maximum height of an element.

```jsx
// hardcoded values
<Box maxHeight="40px" />
<Box maxH="0.4rem" /> // shorthand

// token values
<Box maxHeight="8" />
<Box maxH="10" /> // shorthand
```

## Min height

Use the `minHeight` or `minH` property to set the minimum height of an element.

```jsx
// hardcoded values
<Box minHeight="40px" />
<Box minH="0.4rem" /> // shorthand

// token values
<Box minHeight="8" />
<Box minH="10" /> // shorthand
```

| Prop                | CSS Property | Token Category |
| ------------------- | ------------ | -------------- |
| `h`, `height`       | `height`     | `sizes`        |
| `maxH`, `maxHeight` | `max-height` | `sizes`        |
| `minH`, `minHeight` | `min-height` | `sizes`        |
