Quines that print what their index is

We all know what a quine is. A quine is a program which prints its own source code. And we also know about the printable ASCII characters. Well... this challenge mixes both.

Your mission, should you accept it, is to create an index quine. An index quine is a non-empty program, composed only of the printable ASCII characters, which prints its own index.

The index of a string is its position within an infinite dictionary where all strings composed of exactly the printable ASCII characters appear, sorted by size then ASCII code.

The index is a non-negative whole number, assigning 0 to the empty string then continuing with the space, !, " onward.

For example, *! precedes ** as the ending ! in the first string has lower ASCII code than the ending * in the second, but both are preceded by {, which has a higher ASCII code than the characters of the last two examples, but is shorter.

The printed index should be in base 10, outputted through STDOUT or closest equivalent, with no other output unless your language requires trailing newlines/other characters. Also, a bit like actual quines, do not access your source code directly (as a file, etc.)

Your program should be non-empty, as a reminder to those reading these rules.

If there are multiple programs of shortest length, the tiebreaker is the program with the lower index.

The shortest program following these very rules wins. Have fun.

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).

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>
MathJax equations \$\sin^2 \theta\$

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
