In 2017, Twitter changed its character limit from 140 to 180. The length distribution of tweets has shifted in response to the rule change, but my discovery from five years ago still holds: a disproportionate number of tweets use all the characters they’re given.

A sample of tweets gathered in 2019 still exhibit a telltale spike approaching the character limit, but it is smaller than the tweet distribution from the 140-character days. The peak of the curve has also shifted leftwards, to 15 characters, presumably due to a separate change that excluded media attachments and certain at-mentions from the character count.

The most interesting feature of the above graph is unfortunately an artifact of the dataset — the massive spike at 105 characters can be blamed on a spambot network broadcasting identical copies of the same tweet when the dataset was collected.
