Good to know before you start
- Circled numbers above 50 and black circled numbers above 20 can’t be made, because they don’t exist as characters.
- Roman numerals cover 1–3999 only. Zero, decimals and numbers of 4000 or more (written with a line above) aren’t supported.
- It doesn’t convert to Chinese or Japanese numerals, or between full-width and half-width digits.
How circled numbers and Roman numerals are written
Circled numbers ① to ⑳ have been around for a long time, while ㉑ to ㊿ were added later. Black circled numbers (❶) only go up to 20, and double circled numbers (⓵) only up to 10. They’re all special Unicode characters: they display fine on newer computers and phones, but old software and some email programs may show other characters instead.
Roman numerals are written by lining up I (1), V (5), X (10), L (50), C (100), D (500) and M (1000) from largest to smallest. Placing a smaller letter to the left means subtraction, so 4 is IV rather than IIII, and 9 is IX. Single symbols like Ⅻ only go up to 12, so from 13 on, symbols are combined, as in ⅩⅢ.
FAQ
Answers to common questions about circled numbers and Roman numerals.
Are the numbers I enter sent anywhere?
No. Everything is converted in the browser on your device, and the numbers and symbols you enter are never sent to a server.
Can I make circled numbers above 50?
No. Circled numbers only exist as characters up to ㊿. If you need 51 or higher, write it in parentheses like (51), or use your word processor’s enclosed character feature.
Why do circled numbers show up as “?” or other characters?
Circled numbers and Roman numeral symbols are special Unicode characters, so they may not display correctly in old software, old email programs or legacy text encodings. In that case, parenthesized numbers like (1) or Roman numerals written with Latin letters (XII) are the safe choice.
Is 4 in Roman numerals IV or IIII?
Usually IV. Clock faces sometimes use IIII, but this tool shows IV. If you enter IIII in “To number”, it shows the correct form (IV).
What’s the difference between Ⅻ and XII?
They look alike, but Ⅻ is a single symbol, while XII is three letters: X, I and I. Use Ⅻ for vertical text or to fit the width of one character, and XII when it needs to be searchable or read reliably in old software.
Are there Roman numeral symbols for 13 and above?
Single symbols only go up to Ⅻ (12). From 13 on, this tool combines symbols, as in ⅩⅢ.
How high can Roman numerals go?
From 1 to 3999. Numbers of 4000 or more need a line drawn above the letters, which can’t be written with ordinary characters. There’s no Roman numeral for 0.
Can I copy ①–⑳ all at once?
Yes. In “Make a numbered sequence”, choose the style and the first and last numbers, then press “Copy all”. You can choose “None”, “Space” or “New line” as the separator.
What forms can it read?
“To number” reads circled, black circled and double circled numbers, parenthesized numbers, numbers with a period, and Roman numerals (XII, xii, Ⅻ and full-width ＸＩＩ). It reads one number at a time.
Is it free?
Yes. No sign-up, and no ads.
