Here are some image dimensions and size guides for your social media marketing branding setup and maintenance. It provides the latest (1/6/2016) image dimensions and size requirements for several social media properties including Facebook, Twitter, Instagram, Pinterest, Google+, YouTube, LinkedIn, and Tumblr.
Facebook Dimensions and Sizes

Facebook profile picture dimensions – size: 180 x 180 (min. 160 x 160)
Timeline – Newsfeed photo: 1200 x 900 (min. none)
Facebook Ad Dimensions – Specs: 1200 x 628
Facebook is the most popular social media site right now in the world. It is imperative you have the right picture, image, and photo sizes. Keep in mind that both your cover photo and profile picture image dimensions will be cropped to fit a square. Make sure the important images and text are visible. On smartphones, your cover photo will display at 640 x 360 pixels.
Twitter Dimensions and Sizes
Twitter header size dimensions: 1500 x 500 (min. none)
Twitter profile picture size: 400 x 400 (min. 200 x 200)
Twitter image size: 506 x 253 (min. 440 x 220)
Like Facebook, your Twitter profile pic will shrink to a smaller display. So make sure you have your important imaging/logo in the most optimal places. The Twitter banner and header size is larger. You can utilize this to your branding advantage.
Instagram Dimensions and Sizes
Instagram photo size: 110 x 110
Instagram does not have a header image/cover photo (removed in 2015). You only need to worry about your Instagram profile picture size and other Instagram picture sizes. Ideal Instagram photo size requirements are 602 x 752 for Portraits, 602 x 602 for Square size, and 600 x 314 for landscape picture sizes and panoramic picture frames.
Pinterest Dimensions and Sizes
Pinterest profile pic: ~61 x 61
Pinterest Image Size: Varies
There’s no exact optimal size for Pinterest pins. Even the Pinterest profile image size is a suggested size. Instead, choose an appropriate size for each new image that will look appropriate with your other pinned images.
Google+ Dimensions and Sizes
Google Plus profile picture: 250 x 250 (recommended)
Google Plus cover photo size: 1080 x 608 (recommended)
Your Google Plus cover photo size can go as small as 480 x 270 or as big as 2120 x 1192. But the recommended size will work fine. Google Plus has a similar cover photo size as Twitter’s. The larger the cover photo size, the more room for branding.
YouTube Dimensions and Sizes
YouTube Channel Art – Cover photo, Size/Dimensions: 2560 x 1440
YouTube Profile Picture: 100 x 100
Channel art is also known as a YouTube Banner or cover photo. You may want to consider using the 1546 x 423 “safe area” for your channel art. This guarantees your text and logos won’t get cut off from the YouTube banner size. This is also the smallest size you can upload. You can also create a branded full size YouTube banner, which is recommended.
LinkedIn Dimensions and Sizes
LinkedIn profile picture size: 200 x 200
LinkedIn profile background photo: 1400 x 425
