The largest Roman numeral which will fit in a Tweet is an "M" plus 279 overbars, which expresses exactly 10^840, as I shall now demonstrate

This is actually significantly larger than the largest Arabic numeral which will fit in a Tweet, which is 280 "9" digits in a row, expressing 10^280 - 1

However, plenty of Roman numerals for smaller values, such as 10^840 - 1, won't fit at all

The smallest number whose Roman numeral won't fit in a Tweet is, I believe, 78,888,888,888,887,888,888. Everything up to 78,888,888,888,887,888,887 fits (see next Tweet)

Ah! I think my earlier calculation was wrong. The smallest number which has a 281-character Roman numeral is actually 38,888,888,888,887,888,888, not 78,888,888,888,887,888,888. So the answer to the question is 38,888,888,888,887,888,887 (see next Tweet):
