The best export settings for Instagram 2018
Gah! This image looks like it was shot from a potato. Pixelated, soft, full of artefacts. Gross.
…or maybe I was being too hard on myself once upon a time.
Either way, if Instagram is killing your images after you’ve spent time perfecting them in Lightroom, this article is for you. I’ll teach you the best export settings for Instagram in 2018, and if you stick around, there’s some freebies at the end.
So, Instagram has some recommended guidelines for images. Basically:
- Aspect ratios will be between 1.91:1 and 4:5.
- They will always be cropped to fit at 1080 pixels wide unless it’s exactly that size.
Some other things we do know, though, is that Instagram also uses what’s called an image compression algorithm on all images that get uploaded to their servers.
The compression myth
The reason why they do this is the same reason why many websites squash images too (including this website you’re reading this on!) – performance. Instagram is optimising for images to load as fast as they can for the best experience, so they try and reduce the file sizes of your images so there’s less to download and thus your feeds load quicker.
Warning: this next bit gets a tad technical.
Some image compression techniques are better than others, and to be quite honest, Instagram’s is actually quite good – a decent quality for the file size. However some people find problems with it, and that’s where this article comes in.
But first, let’s dispel a myth that there’s a ‘quality’ or file size you can get to in order to avoid the compression algorithm.
I’ve seen some people say that if you set your export settings to 75% quality, or if your images are under 500kb, you’ll somehow magically bypass the compression algorithm.
That’s a total lie.
In fact, by doing so, you’re actually making your end image worse than what it could be. Here’s why.
The upload process looks a little like this:
- A user sets up and shares their image
- The image goes into the server
- The server compresses the base image
- It then makes copies of that compressed image, resizing at 150px, 240px, 320px, 480px, 640px and 1080px in what’s called a source set (srcset) so that it can show you the most relevant size of your image depending on where it’s viewed
- In the feed you usually see the 1080px wide version.
Every image is compressed. It needs to be that way because it doesn’t make logical sense to assume that the user’s compression is better than their own. There’s too many variables, and therefore the most reasonable approach is to standardise all images, even if it ends up being parity or just a check.
You can test this yourself. Upload an image at 50% quality at less than 500kb and extract that image from the desktop version of Instagram (right click > inspect element on your image > expand the sibling DIV > right click to open your image in a new tab > save) and compare it to your original image. The actual quality of the algorithm is quite good – compressing file size considerably at little loss of quality – so it’ll be hard to tell, but there’s definitely compression there.
Therefore, if you’re uploading at 75% quality, then you’re compressing 75% quality. Alternatively, if you upload at 100%, you also compress at 100%.
The best export settings for Instagram in Lightroom
With that said, there are 6 dimensions to consider when exporting for Instagram.
This is actually the biggest deal when it comes to what looks like a high quality image.
Sharpness is usually perceived as detail, and a more detailed image looks better generally.
As with all formats, whether it’s print or digital, you need to sharpen for your medium. Typically, you’ll have different sharpening levels if you’re getting your image printed vs being viewed on a mobile device. This is because depending on what medium you’re viewing the image on, there are variables in the quality of your viewing experience.
How many pixels per inch does your phone pack into its display? How many dots per inch is your printer printing your image at? What material and size? What about the size of your display? How far are they standing away from the image? What size is it seen at? All of these variables and many more determine how good your image looks when someone is viewing it.
That’s a long-winded way to say that you need to sharpen for a phone display. And although you can do that by setting your “Output sharpening” to “Screen”, we can do better.
Check out this article on how to sharpen images in Lightroom. The juicy part is at number 5. TLDR; use masking.
Once you’ve sharpened your shot, send it to your phone. If it looks like it’s almost too sharp, you’re golden. The compression will dull it down when you upload it.
While Instagram supports every ratio between 1.91:1 and 4:5, there’s only really one crop size you should be uploading at – 4:5.
4:5 turns out to be the largest pixel size you can upload. It not only gives you the most digital real estate to work with in your photo, but it also takes up the most size in the feed.
Due to the nature of their aspect ratio in the portrait orientation of a phone, when your audience scrolls through their feeds, unfortunately the landscape images – the little images – get skipped over pretty fast.
Square images are better, but 4:5 images are the best.
(For the record, I prefer to shoot and showcase my work in landscape mostly, but eh, you gotta change with the times!)
If you missed it, read the previous section on “The compression myth”, but this section is otherwise pretty straight forward.
Best quality. No limit. JPEG or PNG. Size be dammed. That’s what the image compression algorithm is for. It’s going to be compressed regardless of what you do.
There are a few choices for what colour space you can export to. Many printers prefer their files in AdobeRGB (1998) because the colour space is wide and varied enough for the subtle changes in tonality, while matching with what most physical printers print at.
For digital, we’re looking for sRGB. The majority of digital is sRGB – that’s what you should be editing with and that’s what you should be exporting at for the most consistent experience.
Instagram always displays images at 1080px. In their guidelines, they say that they skip the resizing process if your uploaded image is equal to or less than that resolution.
There’s two approaches here:
1) Export at 1080px wide. That means:
- Square: 1080px x 1080px
- 4:5: 1080px x 1350px
2) Export at exactly double 1080px wide.
One of the reasons why I do this is because if Instagram wants to increase the displayed image sizes in the future, they have a 2x version of my image that they can re-splice a source set from.
But the main reason is that exactly 2x or 4x resized downwards will always be kind and safe to whatever resizing work is going on in the background. In some cases, it’s even sharper (for example: cameras downsampling from 6k to 4k for a superior, sharper image like in the Sony A6500).
- Square: 2160px x 2160px
- 4:5: 2160px x 2700px
When it comes to resolution, displays typically show a maximum resolution of 72 pixels per inch (PPI), while for print, selecting a resolution of 300 dots per inch (DPI) in generally preferred.
For our use case, 72 PPI will do. Any more will not have any visible benefit on quality.
Instagram strips all your metadata. Up to you if you want to export any out, but by the time you upload it, it’s gone and it never comes back.
