As you can see in the first image (a Twitter tweet in the feed), a lot of the text on the image has been cropped out and would require a someone to click on the image to actually see the full message. This is what you should aim to avoid, your message should be clear without having to click on it. The second image is an easy enough mistake to happen, it’s a picture taken on a phone I presume but Twitter has chosen to focus on the wrong part of the image. Resizing your image before uploading it is best, or as quick fix take landscape photos instead of portrait as this is better for most social media platforms. Always be thinking how your image will display on Facebook, Twitter when put in a post/tweet etc.
On Facebook ensuring your image is the correct dimensions is vitally important also, particularly for adverts, profile pictures, cover images, newsfeed images and your Open Graph meta tags (image shown when a link on your website is shared). So many different variable sizes apply to each so often one image will not fit all.
Profile Photos & Cover Photos
Most social media platforms use a squared image for profile pictures. Usually this should be your business logo (high quality) and then use the cover photo to convey your brand’s image or latest offerings. If your logo is quite wide or tall you will need to ensure it has enough space around it in the background so that it displays fully without the need to click & expand.
A cover photo is the full width image (banner) that displays at the top behind your profile photo. This is an exceptional tool for use in social media marketing. You can instantly convey what your business or brand does as well as including a message.
