When you’re exporting images from Lightroom to Instagram, the most important settings to consider are aspect ratio and width. Here’s what and how to do it.

Best Instagram aspect ratio

Before exporting your photo, you need to know what the best image sizes are for Instagram.

Currently, the best Instagram aspect ratio’s are 1.91:1 for horizontal images and 4:5 for vertical images. Of course, you can crop the image as a square or 1:1.

As far as width, Instagram recommends 1080 pixels wide.

Photo OrientationAspect Ratio
Vertical (Portrait)4:5
Horizontal (Landscape)1.91:1

Image resolution

The longest side of a vertical image can go up to 1,350 pixels on the Retina display, and the longest side for horizontal images is up to 1,080 pixels.

If you upload a photo wider than 1080 pixels, Instagram will automatically resize the image for you. This causes a loss in image quality which makes it look grainy or slightly blurry.

If you share a photo at a lower resolution, Instagram will enlarge it to a width of 320 pixels automatically. This can cause your image to appear blurry because it’s enlarging a low-resolution image.

By following these guidelines, you can stop Instagram from ruining your photo quality and share great photos.

Color space

Color space is also known as a color model or color system. It defines a range of colors and in photography, these are the colors that your camera can capture.

When you go to your camera’s settings, you’ll see sRGB and Adobe RGB. RGB stands for Red, Green, and Blue. All of the colors created in RGB are a combination of these colors.

sRGB is the default on your camera and is what all online colors are built around. It was created by HP and Microsoft in 1996 to use on monitors, printers, and the Internet.

The benefit of using sRGB is that regardless of where you upload the image, it’ll remain the same.

Adobe RGB is the other option and was created by Adobe Systems, Inc. in 1998 with the purpose to use the same colors that could be achieved with CMYK (Cyan, Magenta, Yellow, and Key which is Black) printers.

Although Adobe RGB has a larger color space, sRGB is more widely accepted which makes for a simple workflow. Adobe RGB should be used if it was specifically requested as it’s usually better for printing and needs to be converted to sRGB for the Internet.
