Custom Twitter backgrounds are popping up all over the place. You’ve probably created on your custom background by now. If you have and want to see how it looks on different screen resolutions Twitter background checker, Twtbg.me, is the place to go. Twtbg shows you your twitter background in the most common screen resolutions ranging from 1024 x 768 to 1900 x 1200.
It can analyze whether your background might have hidden information in a specific resolution or if there’s too much whitespace in your background when viewed from a higher screen res. Simply enter your Twitter handle or a direct link to your background.
