An award-winning collaborative, global project.

This wiki is no longer being updated. But it is still available for anyone who wants to make style decisions based on evidence and data.


Part of: Readability Guidelines

Collaborating on the project

Last updated: 9 April, 2020

It's very important to know: you do not need to be an expert to collaborate and contribute to the Readability Guidelines.

Everyone can join in. If you can use a search engine, like Google, you can help with the project.

We're all just looking for usability evidence.

We share it, and then we have a discussion. It's that simple.


We look at 1 topic each month. You can see in advance how we structure the live discussions.

You can suggest new topics in the comments section on the new topics page.

Being respectful

The only rule we have is to be respectful. It's fine to disagree, respectfully. It's fine to ask for clarification, respectfully, if you do not understand a point someone else is making.

And it's totally fine to ask someone, nicely, if they have evidence to support what they are saying. We cannot include any recommendations without evidence, so you are helping the project by asking that question.

Becoming a super-contributor

If you would like to become a super-contributor, we would like to ask you to make a few super-contributor commitments.

But you can stop being a super-contributor at any time, just let us know.

Requests for advice

The Readability Guidelines project wiki and collaboration channels are set up by Content Design London for the purpose of collecting readability evidence on agreed topics. This is for a shared global goal of making digital content more inclusive.

We do not answer requests for specific advice on something you may be working on, and comments like that will be deleted. The project is run as a not-for-profit undertaking by Content Design London with help from volunteers around the world.

To ask about that sort of thing you're very welcome to try the content design Twitter community or join the Content Design London Club.

To suggest a new readability topic for us all to research and discuss evidence on, please comment on the new topics page.
