Ruh roh! If you’re tweeting out a URL, your tweets just got a bit shorter. Starting Wednesday, any tweet sent with a URL will be reduced to 118 characters, or 117 for https links.
Ok so this is not the end of the world as we know it.

How Do I Make Short URLs on Twitter?

Most URLs are very long. Since Twitter updates are limited to just 140-characters, most URLs are just too long to tweet! Fortunately, you can shorten URLs using a free URL shortener. Just copy the URL you want to tweet, paste it into a URL shortener, and voila — a short URL of approximately 20 characters is returned to you automatically. You can just copy and paste that short URL into your tweet! Follow the link to find a list of popular URL shorteners as well as a comparison of how short URL shorteners make URLs.
