A square of text

The Challenge

Given a string, output the text in the shape of a square.

You can assume that the text will always fit in a square, and that it will never be an empty string.

You can also assume it will never have newlines.

Example

Input:
Hi, world
Output:
Hi,
 wo
rld

Test Cases

Input:
Hi, world! Hello
Output:
Hi, 
worl
d! H
ello
Input:
Lorem ipsum dolor sit amt
Output:
Lorem
 ipsu
m dol
or si
t amt
Input:
H
Output:
H

Rules

This is code-golf, so shortest answer in bytes wins! Tiebreaker is most upvoted answer.
Standard loopholes are forbidden.

Answer*

If this is an answer to a challenge…

…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one. Explanations of your answer make it more interesting to read and are very much encouraged.
…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.

More generally…

…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).

\$\begingroup\$ Nice use of $@, ;) You can save a byte using y///c instead of length and I think you can use a literal new line as well. I was looking as trying to do something with setting ,ドル and matching, but I think this is much shorter! \$\endgroup\$

\$\begingroup\$ @DomHastings Yea, I thought you'd like the $@! Thanks for the y///c, I tend to forget that it exists. \$\endgroup\$

\$\begingroup\$ @DomHastings managed to save 1 byte by using $= instead of $@, which allows to not use -l flag. \$\endgroup\$

\$\begingroup\$ Good going! Good to use the magic variables for genuine reasons too! \$\endgroup\$

\$\begingroup\$ Hey, hope you're doing alright! This got bumped to homepage and I noticed another optimisation for -1: 23 bytes code + 4 for -pF \$\endgroup\$

How to Format

create code fences with backticks ` or tildes ~
```
like so
```
add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
backtick escapes `like _so_`
quote by placing > at start of line
to make links (use https whenever possible)

<https://example.com>

[example](https://example.com)

<a href="https://example.com">example</a>

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. code-golf), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
