A Basic Guide To Posting Images On Social Media

There is more to posting images on social media than simply taking a photo and sticking it online. It’s worth considering which social network you will be using and how it will be displayed.

As a general rule of thumb, try to take photographs in landscape with the focal point vertically and horizontally centred leaving a bit of room to play with on all sides. That way you have a versatile image that can be cropped to a square for Instagram, vertically centred for Twitter and is still decipherable if you post multiple photos to Facebook at once.

If you want to be a bit more clever than here are some useful tips…


Depending on the dimensions of your image, Twitter may not show the full picture in the preview and users will need to click the image to see the rest. If you would like the full image to be seen in the preview, your image should be around 440 x 220 pixels, centred and aligned vertically.

If the original image’s height is equal or less than ½ of the width, the preview image will be same as the image shown when the tweet is expanded. If the image’s height is more than ½ of the width, the top and bottom will be cropped in the preview.

We suggest optimising images for the news feed when possible, because most of your fans will consume content there rather than your page. To make the most of the space, use an image around 1200 x 1000 pixels (or a six by five proportion). That way your image will be aligned centrally on your page and in the newsfeed. Square and tall images are aligned to the left, so it’s safe to use them it’s better to optimise the space available if you can.

Another thing to consider is thumbnail images (the ones that appear when you share a link). There are different ways that Facebook displays thumbnail images with links. Ideally, you want a full-width thumbnail that is scaled to fill a box 484px by 252px. However sometimes the thumbnail doesn’t display full-width, and it goes into a small box at the left instead. In this case, a landscape thumbnails fits in a box 155px wide. This is just something to bear in mind when you upload images to your blog or website.

There is a whole set of different rules for uploading multiple photos. If you want to know more, we recommend this article by ‘’

The main thing you need to remember with Instagram is that the image has to be a square and the app allows you to crop it yourself when you upload it. So if you are taking a landscape photo for Instagram, keep the subject aligned horizontally and if you are taking a portrait photo, keep the subject aligned vertically. You may even have the option on your camera to take a square photo!

There are plenty of cheat sheets out there if you want to get even more technical or learn about posting images to other social networks, but hopefully this has given you a good introduction to what you need for Twitter, Facebook or Instagram.
