Twitter has increased the display name character limit to 50 from the previous limit of 20 characters. The new length means you can also add more emoji without hitting the limit. Notably, Twitter increased the character limit from 140 to 280 for tweets recently.
Starting today, your Twitter display name can be up to 50 characters in length! Go ahead, add that middle name or even a few more emojis. https://t.co/QBxx9Hnn1j
