# zeroPadBytes

```ts theme={null}
function zeroPadBytes(data, length): string
```

Return the DataHexString | **DataHexString** of `data` padded on the **right** to `length` bytes.

If `data` already exceeds %%length%%, a [BufferOverrunError](../interfaces/BufferOverrunError) is thrown.

This pads data the same as **bytes** are in Solidity (e.g. `bytes16`).

| `data`    | [`BytesLike`](/sdk/content/type-aliases/BytesLike) | The data to pad.      |
| `length`  | `number`                                           | The length to pad to. |
