To start, we begin with the world’s largest social network. By having a correctly sized cover photo, profile picture, and shared images, you are well on your way to success. If you need additional help, visit the Facebook Help Center.
It is also important to remember that the dimensions listed above are optimal for uploading images, but that they will be displayed differently on your personal timeline and the news feed of others.
Twitter
- Header photo: 1,500 x 500 pixels
- Profile Picture: 400 x 400 pixels (Displays 200 x 200 pixels)
- In-Stream Photo: Minimum 440 x 220 pixels , Maximum 1024 x 512 pixels
While Twitter is designed mostly for conversation through text, images play a big part in how you are viewed and how you communicate. Your profile photo will be viewed on your page, in-stream, and in the “Who to follow” box. Your header photo is the first thing potential followers see when looking at your profile, and adding photos to tweets can help you add variety and build more interest in your brand.
Google Plus
- Cover photo: 1,080 x 608 pixels
- Profile Picture: 250 x 250 pixels
- Shared Photos: 497 x 373 pixels
Because Google+ is directly tied to the search engine it is extremely important to have a professional presence on this channel. Your cover photo is a great place to display your main product or service. Highlighting special offer here is also a great idea, but be careful not to add too much text within the image.
Instagram
- Profile Picture: 110 x 110 pixels
- Shared Photos: 640 x 640 pixels
- Photo thumbnails: 161 x 161 pixels
Instagram is all about photos, and for that reason it is extremely important to have high quality photography. Unlike the other social media channels Instagram automatically creates a header for you, cycling through your past posts. So for your profile picture it is best to have a simple image highlighting your brand.
Pinterest
- Profile Picture: 165 x 165 pixels
- Pin size:
- Main page pin and board pin appear as 236 pixels with height scaled
- Expanded pin appears as 600 pixels with height scaled
Pinterest is a great way to refer traffic to your site. By creating unique pins closely tied to your brand you can get people excited about your product or service. You can link your Pinterest account to Facebook or Twitter, in which case Pinterest will pull your profile picture from those channels. Because Pinterest puts a limit on the width of an image, but not the height, it is great place to showcase your longer images.
