This is a guide to creating character sheets in Roll20, intended for people who aren’t programmers. This covers every aspect of character sheet creation, with the tips focussed specifically on Roll20 design.
It’s divided into the different topics. Make sure to click a heading if you want a better guide and want to know more about that topic. Also, check out Andreas’s Guide for an overview of things.
These three sections cover the basics of sheet authoring. You need some familiarity with these three things.
The elements that form the foundation of a character sheet.
The styling of a character sheet.
This covers articles about sheet authoring on roll20, and transcends specific languages.
These cover skills that many sheets will need once you have mastered the basics.

These articles cover things that are nice to add to a sheet, but which you can do without.
Requires HTML, CSS, Sheet Workers, and Roll Templates, and sometimes Repeating Sections. Very complex, but there are some things you can’t do any other way.
7.b CRP Examples
CRP is very complex, so here are a bunch of examples showing how to use it. (The bulk of this section will go live in November 2023.)
Making one sheet work in multiple languages. Its very tedious to set up, but a lot simpler with Templating (see below).
A noob-friendly tutorial is coming in December 2023, but for new see the Roll20 Wiki’s guide.
More Speculative Stuff
These are things which are only added to a sheet in certain cases, and might not even be possible in come cases. This will be created gradually throughout 2024.
Sheet Templating is a way to create sheets more rapidly, by scripting the repetitive parts. There’s no right way to do this, and several options.
jQuery in Roll20
Coming in 2023-4 (probably – it’s turning out to be less useful than originally envisaged, but Roll20 did state improvements were coming).
A charactermancer is only possible if you have the license for the system. I’ll probably write it up but its not a high priority.
Custom Compendiums are something Roll20 have said will be available, but they do not exist yet. If they do become available, I’ll add instructions here.
