First, How Not to Get Clipped

Search engines like Google do not count characters when they show a headline. They count pixels.

So, if you want to cram a lot into a precious search engine result page’s space,

  • your web site had better be “l.li” and
  • its headline something like Build Skill in Filling Lines with Inky Links.

For the most part, you would also, of course, avoid Roman numerals. They are notoriously wasteful of space—but a joy to behold. With proper Unicode Roman numbers, you can also save a pixel here and there perhaps:

Quick Way to Convert from Arabic to Roman Numbers

For a fast way to find the Roman numeral equivalent for an Arabic number:

  1. Starting from the bottom in the table above, find the first (i.e. largest) number that fits into the Arabic number.
    Exception: Ignore 12 and 11 until you are at either of the numbers directly.
  2. Write that number down in its Roman numeral form.
  3. Subtract the Roman numeral you just wrote down from the Arabic number.
  4. Continue at step 1 with the new Arabic number until you have reached zero.

Roman Numeral Conversion Example

The largest Roman numeral that fits into 753 is Ⅾ for 500. 753 minus 500 is 253.
The largest Roman numeral that fits into 253 is Ⅽ for 100. 253 minus 100 is 153.
The largest Roman numeral that fits into 153 is Ⅽ for 100. 153 minus 100 is 53.
The largest Roman numeral that fits into 53 is Ⅼ for 50. 53 minus 50 is 3.
The largest Roman numeral that fits into 3 is Ⅲ for 3. 3 minus 3 is 0. (Ⅲ is a separate Unicode character. You can also use Ⅰ three times, of course.)

753 as a Roman numeral is ⅮⅭⅭⅬⅢ.
