Social Media Image Sizes 2021: Cheat Sheet for All Social Networks and the GaggleAMP Platform



Let’s cut to the chase - you need social media network dimensions for your creative and we have them. Plus we have a list of dimensions exclusive to the use of the GaggleAMP platform so that everything in your Gaggle appears in tip-top shape. 

Let’s dig in.


Social Media Image Sizes in 2021

Social Media Image Sizes: Why You Need to Get These Right

Globally, 53.6% of the world’s population uses social media an average of 2 hours and 25 minutes a day. That’s a lot of potential exposure so you’ll want to ensure your social media content is in tip-top shape. 

Social media images need to be sized for each platform. It’s important because:

  • Each social network has their own requirements. Just because it renders well on one network doesn’t mean it renders well on another.

  • It avoids pixelation and stretching. When images are properly scaled, they appear more professional and retain your full brand message.

  • Images optimized for your social channel’s feed perform better. Well positioned images increase engagement.

  • It's professional. When your employees share content in your employee advocacy program, it’s a direct reflection of them.

Facebook Image Sizes

When creating content for Facebook, use these recommended sizes.




Facebook Dimension Recommendations:

When pulling together Facebook content, it is best to use the recommended pixel sizes below to aid in faster loading times. Images should be uploaded as a JPG or PNG to avoid distortion.

  • Profile photos will display at 170 x 170 pixels on most computers but can display as small as 128 x 128 pixels on mobile devices.

  • Cover photos are recommended to be 851 x 315 pixels and ideally less than 100MB. On desktop, this will display as 820 x 312 pixels but only 640 x 360 pixels on mobile. Facebook does have a minimum size of 400 x 150 pixels. 

    • Cover photos for events are recommended to be 1200 x 628 pixels and they cannot be changed or edited once they are added to an event.

  • Timeline and post photos are recommended to be 1200 x 630 pixels with a minimum size of 600 x 315 pixels. These images are automatically resized when uploaded to display at 500 pixels wide and to fit an aspect ratio of 1.91:1.

  • Carousel photos: If you have more than one image being uploaded, images should be 1200 x 1200 pixels with a 1:1 ratio.

  • Stories: 1080 x 1920 pixels with an aspect ratio of 9:16. It’s important that the photo does not have a width smaller than 500 pixels. 

    • Pro-Tip: Do you have a story with text? Avoid adding text to your image on the top and bottom of your image (approximately 250 pixels from the top and bottom). Your brands profile photo and/or buttons can cover this area and you do not want it to cover your CTA.

GaggleAMP Facebook Activities

GaggleAMP follows Facebook’s lead in image sizing but does have some limitations when it comes to the Facebook Photo activity.


While all image file types are accepted, including GIFs, you should be aware of the size restrictions on the GaggleAMP platform. Only photos uploaded that are less than 10MB in size will render correctly on the Facebook newsfeed. If an image uploaded is greater than 10MB in size the image may not load correctly on Facebook, despite Facebook having a higher file size requirement. 

Instagram Image Sizes

Unlike other social media platforms, Instagram is a heavily visual platform in which the rendering of your image is front and center. Due to its very visual nature, you’ll need to ensure your content is top-notch to stand apart in the scroll.




Instagram Dimension Recommendations:

  • Profile photos are recommended to be 320 x 320 pixels, and while they upload as a square, they display as a circle so you will need to check your crop.

  • Thumbnails: It's recommended you upload it at 1080 pixels wide but it will render a display size of 161 x 161 pixels. The larger upload is important because while some images render smaller, there are versions of these thumbnails that render as large as 1080 x 1080 pixels.

  • Feed photos render in three different sizes:

    • Landscape: 1080 x 566 pixels

    • Portrait: 1080 x 1350 pixels

    • Square: 1080 x 1080 pixels


It’s important to know that the aspect ratio can vary between 1.91:1 to 4:5. As such, its recommended width of the image is 1080 pixels and has a height between 566 and 1350 pixels, depending on the image type.

If you share an image on Instagram that is over 1080 pixels, Instagram will size it down. And if you upload an image that does not fit the recommended ratio, Instagram will automatically crop the image to fit the ratio.

  • Stories must retain an aspect ratio of 9:16 to avoid awkward cropping. The recommended image size is 1080 x 1920 pixels.

  • IGTV has an aspect ratio of 9:16.

    • Cover photo: 420 x 654 pixels

    • Image: 108- x 1920 pixels

  • Instagram ads have a supported aspect ratio between 1.91:1 and 4:5 with a maximum width of 1080 pixels, and minimum width of 320 pixels.

    • Landscape ad: 1090 x 566 pixels

    • Square: 1080 x 1080 pixels

GaggleAMP Channels

GaggleAMP Channels allow Managers the ability to effortlessly segment content streams to make sure Members are seeing only the relevant Activities and Posts to engage with. Channels can be created by both Managers and Members, and can be Public or Private.

Much like a social media network, Channel Icons are reminiscent of a profile photo, and Channel Banners operate much like a cover photo. Here are some tips on how to use both.


Channel Icons

Channel icons are saved as 128 x 128 pixels. While any file size is accepted, the file will be cropped to 128 x 128 pixels before it saves. 

Images are proportional resized until the smaller of the height and width is equal to 128 pixels. 

Helpful tip:

If you upload an image that is wider than it is tall, the horizontal at 128px will be kept and everything else to the left and right of the center will be cropped out. For example, this original image is 964 x 123 pixels. The number 3 represents the center of a long image, so this is where the crop will start until 128 x 128 pixels are reached. 






If you upload an image that is taller than it is wide, the vertical center will be kept at 128 pixels. Everything above or below this center will be cropped out. For example, this original image is 266 x 1348 pixels. The vertical center is where the number 3 appears, so this is where the crop will start until 128 x 129 pixels are reached. 






Icons can be added to any channel by editing the Channels ‘details’ page and adding an image. If you choose to not include an icon on your Channel, it will not affect your view on a desktop device, but it will appear as a gray circle from your Channel view on mobile.




Channel Banner Images

Channel banners can visually tell your Members what content to expect in the Channel. While any image size is accepted and stored, only a portion of the image will be displayed on the Channel banner. 




Helpful tips:

The aspect ratio is 3.4:1 and if your image is smaller than this ratio, the system will not add any blackspace to buffer the sides. That said, there is no one dimension that is ideal in the banner size, so long as the aspect ratio is 3.4:1.

Just like with the Channel Icons, the Channel Banner will select a portion of the image when the image size is too large. For example, if the image is wider than it is tall, an original image of 964 x 123 pixels will select the center (where the number three appears) but then only display content to the left and right or center for 418 pixels. 





Displayed Banner Image:




In the instance where the image is taller than it is wide, the system will find the vertical center of the image and select the space equal to the original width x the new height. So, in this example an image that is 914 x 1348 pixels will truncate down to 914 x 269 pixels and only render that image on the Channel.

No matter which one you choose, you’re on the road to having an excellent visual display on social media.


Gaggle Icon

Your Gaggle’s icon can be found at the top left corner of every page within the GaggleAMP application.




Gaggle Managers can upload logo image files from within the Gaggle Settings page.


Logo image recommendations

Ideal Aspect ratio - 1:1
Ideal minimal image size - 160x160 pixels

GaggleAMP will accept any image as a logo.  Any image having a height and the width of less than 160 pixels will be saved it in its original form. However, if the height or width is more than 160 pixels, GaggleAMP will proportionally resize the image so the larger of those two dimensions is shrunk down to 160px and saved with those altered dimensions.
Keep in mind that a 24x24 image will occupy roughly the same or less screen space than a 160x160 image, so image quality would be lower with the 24x24 version.
For better control of how the image is displayed, no transparent pixels should be included.
