  This is an experimental post, meant to demonstrate to you the topic we're discussing. I'd love to hear what you think about it.  [Drop me a line](https://twitter.com/irreverentmike) if you find this compelling - I'm hoping to create more like it!

This is -- without exception -- my biggest design-related pet peeve. You've probably come across it yourself from time to time, and if you're lucky, it's not something you noticed. Centering text on a web site, email, or flyer is an easy way to make it appear like a designer's spin has been put on a document. It's an easy change to make in most editors, and in many cases it's probably done without a second thought.

I'll cut to the chase: _center-aligning text is really bad_ in most cases. From a young age, we're trained to read text by starting at the beginning of the line and moving our eyes across the page to the end of the line. From there, it's a relatively low-effort thing to move your eyes back to the beginning of the next line. That all changes when text is centered, since the start of each line is aligned inconsistently. It takes more effort to find the beginning of the next line, to make sure you've only moved down _one_ line, and to continue reading.

## Three great reasons you shouldn't center-align text:

1. A ragged leading-edge makes it harder to move your eyes to the next line of text
2. People with dyslexia may find centered text challenging to read.
3. Lists (like this one) become disorienting to read, and harder to scan

The British Dyslexia Association provides a <a href="https://www.bdadyslexia.org.uk/advice/employers/creating-a-dyslexia-friendly-workplace/dyslexia-friendly-style-guide" target="_blank">dyslexia-friendly style guide</a>, which calls out a simple rule for text:

<Aside type="note">Left align text, without justification.</Aside>

As a designer, this is _such_ an easy win. As a developer, it's often as easy as:

```css

/* change this */
.some-style-rule {
  text-align: center;
}

/* ...to this! */
.some-style-rule {
  text-align: initial;
}

```

## When you _can_ use centered-text

Generally speaking, if you're certain that your text will fit on _one line,_ it may be okay to center it.  This generally applies to page titles, captions on pictures, and things of that nature. Even then, generally speaking my guidance is to avoid it.  Like many other things in design, if there's not a good reason _to_ do it... you're better without.

## Summary
If you're working on a design that relies on centered text, consider other options. If you come across a big blob of centered text in your workplace, or out in the world somewhere, please feel free to use this post as a demo.

Don't center align paragraph text


I often joke that to learn about design is to doom yourself to be lightly annoyed by everything. After some repetition, you'll start to internalize some of the basic rules of industrial design, or print design, or fashion design, or mechanical design, or whatever it is that gets you excited. You'll start to find design quirks in the world which were once hidden to you. After all, every single thing in the built environment has been put there by someone who took their time to bring it to life. The downside, of course, is that you'll also start to see designs that downright suck. I find that it's helpful to think of it as finding opportunity for improvement.

Today's opportunity for improvement is brought to you by [Wikipedia](https://en.wikipedia.org/wiki/Ralph_Waldo_Emerson), which had me going cross-eyed as I read through an article in the early hours of this morning.

<Image
  publicId="posts/all-about-ch/wikipedia-4k"
  alt="Screenshot of a wikipedia article on a wide monitor. Text spans fully from left to right, taking up the full width of available space."
  caption="A fullscreen desktop view of wikipedia on my 4k monitor."
/>

## What is a ch, and why you should c(h)are

It's simple, actually - ch is a CSS unit which represents the width of a character! If you're using a proportional font (where not all characters are the same width), 1ch is the width of the 0 character in the typeface you're using. This is particularly helpful for usability as it relates to reading long passages of text.

## Line length and reading usability - err, readability

Limiting the line width for text in long passages is a great tool for making things more readable. [Studies have shown](https://baymard.com/blog/line-length-readability) that for optimal reading, text should be limited to somewhere around 60 characters per line. Think about it - this is why paperback books are generally smaller than an A4 page. This is why people love reading on their kindle. This is why Barnes and Noble sells Nooks like hotca — well, it's why the Nook is shaped like it is, at least.

In practice, what does this look like? Let's take that same wikipedia article and limit its paragraphs to 60 characters:

```css
p {
  max-width: 60ch;
}
```


Here's what it looks like:

<Image 
  publicId="posts/all-about-ch/wikipedia-ch-applied"
  alt="The same wikipedia article with a limit set on p max-width for ch yields a page that is much easier to consume visually, and is more readable."
  caption="Column width adjusted using the CSS ch unit."
/>

Okay, so that's not a fully-baked design update, but with a few tweaks we can make it a little nicer by bumping up the font size, and adjusting the layout of the right-hand column (side note: wikipedia uses float: right on that column, surprisingly!)

<Image 
  publicId="posts/all-about-ch/wikipedia-ch-adjusted"
  alt="With a few additional layout tweaks, the page can be reflowed around the ch-limited paragraphs, making the entire article more coherent and easier to read."
  caption="Font size bumped up, and right-hand column adjusted to snap in place next to it.  Much easier to read!"
/>

That's not bad at all! One of the nice things about using a character **count** for setting the width of that section is that it scales nicely for folks who use the browser's zoom functionality. You can also put your text passages inside of pixel-size-limited divs to make them work in responsive layouts at smaller sizes:

```html
<style>
  @media screen and (min-width: 800px) {
    .blogpost {
      max-width: 400px;
    }
  }
  .blogpost p {
    max-width: 60ch;
  }
</style>

<div class="blogpost">
