Image Sizing Guide For Social Media

Here is a quick guide for image sizing for social media in 2021, so get it while it’s hot!!

Social media is constantly morphing and changing its rules regarding images.  One minute you have the ideal cover photo for your account, and then because of altered image requirements, it appears resized and pixelated like a 1990’s version of itself. In addition to this, it is difficult to locate the information you need about the standard image sizes for social media, and each platform has different recommendations. Here is a quick guide for image sizing for social media in 2021, so get it while it’s hot — or at least before the rules change again.

Why Are Social Media Image Sizes Important?

When your law firm brand needs great visual content for social media, there are things to get right, such as avoiding copyright laws, finding quality images, and using the best photo optimizing tools. 

Besides this, your social media images need to be sized correctly. This step is essential because properly sized images:

  • Avoid unattractive image stretching
  • Bypass pixelation
  • Stay optimized for the social media feeds
  • Increase engagement
  • Ensure full photo display

Types of Social Media Images 

  • Profile photo. Your law firm logo should appear as your profile photo and match its color and appearance as much as possible. The identical image should appear on each of your social media networks. 
  • Header photo. This image displays at the top of your page. Here you can use a creative, current, eye-catching image. Try updating your header photo when key events happen in your law firm. 
  • Post photos. These are the images that you include in your social media posts to engage visitors and followers. Posting once per day keeps you visible to your audience, while posting too much appears spammy.

Using the right video or image can attract your audience’s attention and keep users engaged, but each platform has its unique optimal size requirements. Sticking to these image guidelines will keep your visual content attractive and its message clear.
