What is a Twitter card?

Twitter cards are designed to give your link tweets a more appealing and structured look to make the interaction with your audience more engaging. Their immersive experience increases the chances of moving more traffic to the shared page.

All you have to do is add a few lines of code to your webpage, and then whenever somebody shares the link of your content, it will show up as a Twitter card to all their followers.

Here, Twitter’s system recognizes the URL in a tweet and crawls the site to fetch the Card type and content to structure the Tweet.

You might not have heard of Twitter cards before, but it is something that you come across every day on your Twitter feeds.

Look at the Twitter card example below. Here, the link to the YouTube video got replaced with this beautiful player card.


Twitter cards are not new. Many people used them before to go beyond the restrictive limit of 140 characters and share more information. Now, the character limit has changed, yet the cards are still in use.

Let’s know more about the Twitter cards.

Types of Twitter cards

Twitter experimented with different card options and had a lead generation card before but discontinued it later. Currently, you get the option to create 4 kinds of Twitter cards.

Each card has a different visual experience based on the type of media they support. You need to choose which kind of card you want to implement.

Note: You can only have one Card per page.

1. Twitter Summary Card

As the name suggests, the summary card gives a proper brief of the web page you share, which includes a thumbnail, title, description, and the URL of the page.


Summary cards are a great way to showcase many kinds of web content, such as blog posts, news articles, eCommerce products, and restaurant reviews.

The brief description in the card itself works as a great call-to-action for your user to click on the tweet and go to your content.

How to add the Twitter summary card to your site?

To add the summary card, you must paste the below-written codes to your website header with proper attributions.

  • First, you define the card type.
<meta name="twitter:card" content="summary" />
  • Then provide the @username of the account the card should be attributed to.
<meta name="twitter:site" content="@username" />
  • Next, write a crisp title for the content page. The title on Android and iOS apps will be truncated to two lines, and in one line on the web viewing. So, keep it under 70 characters.
<meta name="twitter:title" content="Title of your webpage" />

A 200-character description to summarize the content page properly. Remember not to use the title as a description. That would be a waste.

<meta name="twitter:description" content="Description" />
  • Now give the URL of the image to appear on the Twitter card.
<meta name="twitter:image" content="image URL" />

For best results, use the following dimensions and character limits:

Title: 70 characters

Description: 200 characters

Supported Image dimension: Aspect ratio 1:1, minimum dimension 144X144 pixels, and maximum 4096×4096 pixels.

Image size: Less than 5 MB

2. Twitter Summary Card with large image

Think Summary card but with a large image.

The summary card with a large image has the same functionality as the typical summary card but with the exception that you can add a large image.


Brands use it to emphasize the visual elements of the webpage. A large structured image can be an excellent scroll stopper amid a crowded Twitter timeline.

How to add a Twitter summary card with a large image to your site?

Below are the meta tags you need to add to your site to implement summary cards with a large image to your tweets.

<meta name=”twitter:card” content=”summary_large_image”>
<meta name=”twitter:site” content=”@yourwebsite”>
<meta name=”twitter:creator” content=”@yourtwitterhandle”>
<meta name=”twitter:title” content=”your title”>
<meta name=”twitter:description” content=”your description.”>
<meta name=”twitter:image” content=”image URL">

Dimensions for the summary card with large image:

Title: 70 characters

Description: 200 characters

Supported Image dimension: Aspect ratio of 2:1 with minimum dimensions of 300×157 or maximum of 4096×4096 pixels.

Image size: Less than 5 MB

3. Twitter App Card

Besides promoting website content, Twitter is also a remarkable place to promote your application to drive installs. After all, 80% of Twitter users access the platform on a mobile device.

With the app card feature, promoting your application becomes more interesting. App card is a great way to promote your app on Twitter for more downloads.

It showcases the name, icon, description, and even information like the price and rating of your application.


On a side note, make sure that your application is publicly available on the app stores; otherwise, Twitter won’t be able to pull out the necessary data to create an app card.

How to add an App card to your site?

  • To add an App card, paste the following codes into your webpage HTML:
<meta name=”twitter:card” content=”app”>
<meta name=”twitter:site” content=”@yourwebsite”>
<meta name=”twitter:description” content=”your description”>
  • By default, Twitter pulls out the data from US stores, so if your app is available in a different country, then define the country name using the below tag.
<meta name=”twitter:app:country” content=”your country like US”>
  • Next, you define the name, app id, and the URL of your application in the App store.
<meta name=”twitter:app:name:iphone” content=”your iphone app name”>
<meta name=”twitter:app:id:iphone” content=”your iphone app ID”>
<meta name=”twitter:app:url:iphone” content=”your iphone app URL”>
  • Tags for an iPad-optimized app. If your app is not optimized for iPad, fill in the tags the same way you did for iPhone.
<meta name=”twitter:app:name:ipad” content=”your ipad app name”>
<meta name=”twitter:app:id:ipad” content=”your ipad app ID”>
<meta name=”twitter:app:url:ipad” content=”your ipad app URL”>
  • Define the same parameters for your app present on Google Play.
<meta name=”twitter:app:name:googleplay” content=”your googleplay app name”>
<meta name=”twitter:app:id:googleplay” content=”your googleplay app ID”>
<meta name="twitter:app:url:googleplay" content="your Google Play app URL ">

Dimension to keep in mind for the App card:

Title: Fetched from your app id

Description: 200 characters

Image: The image uploaded to the iTunes/Google Play store must be less than 1 MB in size

4. Twitter Player Card

Video has been the king of content marketing, and with the emergence of audio platforms like Twitter spaces, audio has also started to take the front seat in Twitter marketing.

Luckily, the player card supports both media types and provides a richer experience to users around Twitter.

What do they do?

Player cards automatically pull out the video or audio present in the link and play it right there in the timeline or feed, so users don’t have to leave the app just to interact with the multimedia.


The card is an excellent way to promote new product videos, podcast snippets, behind-the-scenes, and brand events.

How to add a player card to your site?

Below are the sample codes you need to paste into your webpage HTML:

 <meta name="twitter:card" content="player" />
<meta name="twitter:site" content="@username" />
<meta name="twitter:title" content="Title of your video" />
<meta name="twitter:description" content="Description." />
<meta name="twitter:image" content="Image URL" />
<meta name="twitter:player" content="https://yoursite.com/container.html" />
<meta name="twitter:player:width" content="Width" />
<meta name="twitter:player:height" content="Height" />
