# Paper Sizes

When creating a new document or adding a new page to your current document, PDFKit allows you to set the page dimensions. To improve convenience, PDFKit has a number of predefined page sizes. These sizes are based on the most commonly used standard page sizes. 

### Predefined Page Sizes

### Setting the page size

In order to use the predefined sizes, the name of the size (as named in the lists above) should be passed to either the `PDFDocument` constructor or the `addPage()` function in the `size` property of the `options` object, as shown in the example below, using `A7` as the preferred size. 

    // Passing size to the constructor
    const doc = new PDFDocument({size: 'A7'});
        
    // Passing size to the addPage function
    doc.addPage({size: 'A7'});
