Ghost Config

Ghost themes include a package.json file with predefined configuration. You can edit this file to change theme-level behavior like pagination and responsive image sizes.

Posts per page

The posts_per_page value defines how many posts appear in the blog list before pagination. You can change it in the theme package.json file:

"config": {
    ...
    "posts_per_page": 8,
    ...
}

Image sizes

Ghost can handle responsive image sizes, and this is defined in the package.json file, under the image_sizes property:

"config": {
    ...
    "image_sizes": {
        "140": {
            "width": 140
        },
        "200": {
            "width": 200
        },
        "400": {
            "width": 400
        },
        "600": {
            "width": 600
        },
        "1200": {
            "width": 1200
        },
        "2000": {
            "width": 2000
        }
    },
    ...
}

The image sizes defined there will be used to generate copies of images at the specified sizes when uploading images in Ghost Admin.
