An A4 sheet for the 2024 rules that fits a whole character on two sides: the numbers touched every round on the front, and everything the character actually is on the back.
The front holds the six abilities with their modifiers and saving throws, the skill list with proficiency, armour class, initiative, speed, hit points and hit dice, and a table of attacks with bonus and damage. The back is spells, features and traits, equipment, proficiencies and languages, and the four paragraphs that make a character worth playing: personality, ideals, bonds and flaws.
Export gives a PDF whose boxes are real form fields, a blank copy for a table that prefers pencils, and a 300 DPI PNG of either side. On 120 g paper the sheet takes an eraser for a whole campaign without going furry.
The layout is unofficial and made for play at your own table. It includes material from the SRD 5.2 under the Creative Commons Attribution 4.0 licence, and the sheet carries that attribution in small print so the printed copy travels with it. Printing handouts covers the paper.
