What Is a Dimension in Google Analytics 4?

In Google Analytics 4 (GA4), dimensions are data attributes or characteristics that provide additional information about your website’s users and how they interact with your website.

Dimensions provide context that makes your data meaningful. Like in the image below:

For example, the “Country” dimension indicates where a website visitor is located. Which means you can see how many visitors came from different countries.

Or it could be the “Device Category” dimension. Which reveals which kinds of devices your visitors use to access your site.

Examples of dimensions are:

• Device category: The type of device user activity originated from (e.g., desktop)
• Source / medium: The referring website/platform (e.g., Facebook) and the broader channel category that refers the visit (e.g., “email”)
• Browser: The browser used to access content (e.g., Chrome)
• Country: Geographical location of the user (e.g., United States)
• Language: The language the user’s browser or device uses (e.g., English)
• Campaign / Campaign ID: The name of a marketing campaign that led to a conversion (e.g., “Spring2023_Sale”)
• Page location: The URL of a webpage the user visited (e.g., “https://www.yourwebsite.com/blog/how-to-train-a-puppy”)
• Custom dimensions:The dimensions you create yourself to track specific information about your users
