What size is a Ford Focus rear window?

There's no single answer to the size of a Ford Focus rear window. The dimensions vary slightly depending on the model year and body style (hatchback vs. sedan). You'd need to specify the exact year and model of the Ford Focus to get an accurate measurement. Even then, you might find slight variations due to manufacturing tolerances.

To find the exact dimensions, your best bet would be:

* Checking your owner's manual: It might list the dimensions or provide a diagram.

* Contacting a Ford dealership: They should be able to provide specifications for your specific vehicle.

* Searching online for your specific model year and body style: Some automotive parts websites might list the glass dimensions.

Without more specific information, I cannot give you a precise answer.
