Instagram prioritizes photos and videos on its platform, which include;
- Single Posts
- Carousels
- Reels
- Stories
- And IG Lives
A couple of key points to always consider before posting to Instagram is:
- Instagram will resize all the photos you attach in a carousel based on the aspect ratio of the first photo. What does this mean? If the images or graphics you decide to post are all different sizes, Instagram will simply crop your images or graphics to fit one size! It is always best practice to post images or graphics that are all the same aspect ratio to avoid any weird cropping to happen.
- The max amount of photos or videos you can post on a single carousel is 20!
- Your grid on your profile is now resized to a 4:5 aspect ratio. What does this mean? Before your grid was sized to be a 1:1 aspect ratio, which was a perfect square. With its latest update, it is now at a 4:5 aspect ratio, which means any post going forward should be fitted with that aspect ratio.
- What is the 4:5 aspect ratio in pixels? We recommend 1080×1350
- Be sure that your videos are no larger than 4GB.
We recommend following these size guidelines to ensure that your photos are not cropped or distorted when posting.
- Profile Picture: 320×320 aspect ratio of 1:1

- Single Posts: 1080×1350 aspect ratio of 4:5
- IGTV: 1920×1080 aspect ratio of 16:9
- Reels and Stories: 1080×1920 aspect ratio of 9:16
- Be sure to only place your text and important information within the safe zones!
- Stories: need a cushion of 250px on the top and bottom of your graphic or image
- Reels: need a cushion of space 250px from the top, 350px from the bottom, and 193px from the right-hand side.
- Be sure to only place your text and important information within the safe zones!

Facebook is similar to Instagram as these platforms can be integrated into one another, however, there are some key differences that every graphic designer should take notice of.
- Keep PNG files below 1MB, otherwise they may appear pixelated.
- For best results, make sure your image is in JPG format, with RGB color, and less than 15MB.
- When sharing 2-10 images aim to have your images sized at 1200×1200.
- When you upload multiple photos to Facebook, the feed automatically arranges them into a grid and crops them based on the number of images in the post, disregarding their original aspect ratios.
