Twitter Cards Explained


Perhaps you have recently noticed some pretty tweets appearing on your Twitter stream, these are performed by people who have successfully implemented the relatively new Twitter Card metadata protocol. Similar in several ways to Open Graph, Twitter Card is a simple mark-up that allows you enrich how your content appears when tweeted.

With Twitter Cards, you can attach videos, rich photos as well as media experience to Tweets that drive audience to your site. All you need do is to simply add a few lines of HTML to your webpage , and users who Tweet links to your content will have a “Card” added to the Tweet that is visible to every of their followers. In addition to the URL and copy, there are several card types you would like to appear whenever the URL is tweeted.

Summary Card

This card can be utilised for diverse web contents, from news articles and blog posts, to products and services. Summary card is designed to provide the reader with a preview of the content before clicking through to your site. The dimension of the image must be at least 120px by 120px and the file size must not be more than 1MB. For a timeline, the image will be cropped to 4:3 aspect ratio and resized so as to be displayed at 120px by 90px. Likewise for embedded tweets, the image will be cropped and resized to 120px by 120px.

Sample code:

<meta name="twitter:card" content="summary"/>
<meta name="twitter:site" content="@flickr"/>
<meta name="twitter:title" content="Small Island Developing States Photo Submission"/>
<meta name="twitter:description" content="View the album on Flickr."/>
<meta name="twitter:image" content="https://farm6.staticflickr.com/5510/1433952_93595258ff_z.jpg"/>

 

Summary Card with Large Image

The Summary Card with Large Image offers a great, full-width notable photo together with a tweet. It is built to provide the audience with a rich-photo experience and on tapping on the picture leads the user to your website.

The description text box is truncated to 200 characters therefore, you should use that space to briefly summarise the content of the page as appropriate for presentation within a Tweet.

Image: URL to a unique image representing the content of the page and should be able to drag an attention (funny photos, intensive colours or graphics). It is not a good practice to use a generic image such as your author photo, website logo or other image that spans multiple pages. Images for these Cards should be at least 280px by 150px but must be less than 1MB in file size.


Sample code:

<meta name="twitter:card" content="summary_large_image"/>
<meta name="twitter:site" content="@nytimes"/>
<meta name="twitter:creator" content="@SarahMaslinNir"/>
<meta name="twitter:title" content="Parade of Fans for Houston’s Funeral"/>
<meta name="twitter:description" content="NEWARK - The guest list and parade of limousines with celebrities emerging from them seemed more suited to a red carpet event in Hollywood or New York than than a gritty stretch of Sussex Avenue near the former site of the James M. Baxter Terrace public housing project here."/>

Single Photo Card

The Photo Card places the image at the front and centre in the Tweet. Whenever you click on the photo, the photo card expands it to a richer, detailed view. Twitter resizes images while maintaining the original aspect ratio to fit the following sizes:

  • Web: maximum length of 375px, maximum breadth of 435px
  • Mobile (non-retina screens): maximum length of 375px, maximum breadth of 280px
  • Mobile (retina screens): maximum length of 750px, maximum breadth of 560px

Twitter will never create a photo card if the image size is less than 280px by 150pxl. Images will not be cropped unless they have an exceptional aspect ratio, the size of the images must be less than 1MB and the images will be fetched and proxied by Twitter to ensure a high quality service and SSL security for users.


Sample code:

<meta name="twitter:card" content="photo"/>
<meta name="twitter:site" content="@flickr"/>
<meta name="twitter:title" content="Mountain sunset"/>
<meta name="twitter:image" content="http://farm8.staticflickr.com/7334/11858349453_e3f18e5881_z.jpg"/>
<meta name="twitter:url" content="https://www.flickr.com/photos/reza-sina/11858349453/"/>

 

Gallery Card

The gallery card shares a photo collection with your Twitter audience. It allows you to embed up to four photos in a tweet. Also, the Gallery Card allows you to represent collections of photos within a Tweet. This Card type is designed to let the user realize that there is more than just a single image at the URL shared but rather, a gallery of related images. The maximum allowed description length of the content is 200 characters.


Sample code:

<meta name="twitter:card" content="gallery"/>
<meta name="twitter:site" content="@fodorstravel"/>
<meta name="twitter:creator" content="@fodorstravel"/>
<meta name="twitter:title" content="America's Best Small Towns"/>
<meta name="twitter:description" content="For the second year in a row, we've compiled a list that highlights some of the best places in the country you don't hear about every day." />
<meta name="twitter:url" content="http://www.fodors.com/news/photos/americas-best-small-towns"/>
<meta name="twitter:image0" content="http://www.fodors.com/ee/files/slideshows/telluride-resized.jpg"/>
<meta name="twitter:image1" content="http://www.fodors.com/ee/files/slideshows/shutterstock_18216130-resized.jpg"/>

<meta name="twitter:image3" content="http://www.fodors.com/ee/files/slideshows/4-maui-hawaii.jpg"/>

 

Product Card

The Product Card is a better way to represent retail items and products on Twitter. This type of card is designed to showcase your products by means of a description, an image and allow you to highlight two other key details about your product.

The Product Card requires an image size of 160 x 160 or greater. Although it prefers a square image, we can resize/crop oddly shaped images to fit as long as both dimensions are greater than or equal to 160 pixels.

App Card

The App Card is an excellent way to include mobile apps on Twitter as well as to drive set ups. It is unique, just like we utilize each of the respective app stores (Google Play, Apple iTunes) to proxy the pertinent Card data. If you specify the Card type, and each of the corresponding App IDs to the respective app stores, our system will proxy the rest for you (number of reviews, number of stars for the app etc.). You can as well optionally specify a more concise description of your application.

The App Card is built to accommodate name, icon and description, as well as to emphasize qualities like the price and the rating. When applying and evaluating your App Card, be sure that the app is publicly available in an app store, else Twitter will not be able to gather its details. Likewise by default, the system examines the US store therefore if your application is located in other countries, make sure to specify this by using the Twitter country Meta tag.

The picture for the Apps Card is likewise downloaded straight from the apps store wherein your app is located. Ensure your App Card works properly and the size of the image uploaded to the Google Play store/iTunes is less than 1MB.


Sample code:

<meta name="twitter:card" content="app" />
<meta name="twitter:site" content="@TwitterDev" />
<meta name="twitter:description" content="Cannonball is the fun way to create and share stories and poems on your phone. Start with a beautiful image from the gallery, then choose words to complete the story and share it with friends." />
<meta name="twitter:app:country" content="US" />
