After searching numerous articles regarding banner sizes for steemit banners, I finally found out that trying it for myself will be the best way. So I discovered the banner size 1200 X 155 px is the perfect size.
I used Canva and chose custom dimensions, works like a charm...
After creating th image/banner I downloaded it, uploaded it to Postimg.org and used the Direct link URL to add it to my profile. Short and sweet, works like a charm.
