Make sure your images are always at their best
If you use your phone to post directly to Instagram then you probably don't need to worry too much about image sizes. However, if like me you use Photoshop or some other editing software, it's good to know the right size for whatever you are posting. As the bods behind the app are constantly tweaking it, so Instagram image sizes are changing. I found a useful article the other day which summarises all the sizes you'll need for the immediate future.
As with most other social media sites and apps, the profile photo is circular. You don't have to worry about creating a round image, just make sure your image is square and Instagram will place a frame over it. But make sure your square image is of the right size, and that is 320px x 320px.
If you haven't uploaded a profile photo for some time it could be worth doing it again with the right dimensions. This will ensure that your profile photo is sharp not just on a mobile device but also on larger HD screens. Upload an image that is bigger than this and Instagram will resize it automatically, possibly affecting the way it appears on screen.
Square image posts
The square is still without doubt the most popular format for Instagram posts, and the size is 1080px x 1080px. If you upload an image which is smaller or larger than this, you've guessed it, Instagram will resize it. As someone who likes to zoom in on details in images, I hate it when I get a grainy imaged. This is due to small images being uploaded and suffering from being resized.
This is easy enough to remember: the horizontal width should be 1080px. When you resize your image in your editing software make sure that you constrain the aspect ratio.
I'm sure you'll notice a pattern developing here. The horizontal width should be a maximum of 1080px. But watch out because there is also a maximum vertical length too, of 1350px. If you upload an image which is 1080px wide but 1600px long, then Instagram will crop the bottom 250px off your image to fit the 1350px length.
Stories use the entire screen area which means that you can go bigger, but wait for it... the maximum horizontal width is 1080px! The maximum vertical length is 1920px. One other thing to bear in mind is that Instagram adds an overlay to the story with your username at the top, and various buttons at the bottom like the Send Message box.
