Online list generator instantly builds a sequence from 1 to 20 in Roman numerals.

Ideal for numbering documents, books, event plans, and other structured lists with classical Roman numeration. Supports vertical or horizontal layout, any delimiter, and optional wrapping symbols.

How to create a 1–20 Roman-numeral list

The range 1–20 is set automatically. Adjust four settings:

Format: choose “Column” or “Row”.
Delimiter: comma, period, dash, space, “/”, “|”, comma + space, period + space, or your own symbol.
Preview: the result appears instantly in the preview pane.
Copy: click “Generate”, then “Copy”—the list goes to the clipboard.

Additional settings

Step (interval): enter an integer—for example, 3 → III, VI, IX… or 10 → X, XX, XXX….

I, IV, VII, X, XIII, XVI, XIX, XXII, XXV, XXVIII

Wrapper: add characters before and after each numeral (parentheses, quotation marks, etc.).

(I), (II), (III), (IV), (V), (VI), (VII), (VIII), (IX), (X)

Delimiters

Select no delimiter (for column view) or a symbol from the menu. For custom marks, choose “Custom”.

Type	Symbol	Example
Comma	,	I,II,III,IV,V
Comma + space	,	I, II, III, IV, V
Space		I II III IV V
Dash	–	I–II–III–IV–V
Period	.	I.II.III.IV.V
Period + space	.	I. II. III. IV. V
Vertical bar	\|	I\|II\|III\|IV\|V
Slash	/	I/II/III/IV/V

Wrapper

Default: none. To add your own, pick “Custom” and enter the symbols.

Type	Before	After	Example
Parentheses	(	)	(I)
Square brackets	[	]	[I]
Curly braces	{	}	{I}
Angle brackets	<	>	<I>
