The size parameter allows you to control the dimensions of the generated PDF document.

​

Overview

When rendering a PDF, you can specify the page size either by using standard paper size presets (like A4, Letter) or by defining custom dimensions with a specific unit of measurement.

​

Parameter details

​

Usage

​

Using a preset:

{
  "parts": "https://example.com",
  "size": {
    "preset": "a4"
  }
}

​

Using custom dimensions:

{
  "parts": "https://example.com",
  "size": {
    "width": 210,
    "height": 297,
    "unit": "mm"
  }
}

​

Behavior

• When using a preset, any provided width and height values are ignored.
• The preset property takes precedence over custom dimensions if both are provided.
• If neither preset nor custom dimensions are specified, the default A4 size is used.

​

Available presets

The following standard paper size presets are available:

​

Use cases

This parameter is particularly useful for:

1. Standardized documents: Use presets like a4 or letter for documents that need to conform to standard paper sizes.

2. Custom publications: Create custom-sized documents for specialized publications like brochures, cards, or posters.

3. Print-ready output: Ensure your PDFs match the exact dimensions required by your printing service.

​

Example

Creating a business card-sized PDF:

{
  "parts": "<div style='text-align: center;'><h2>John Doe</h2><p>Software Engineer</p><p>john@example.com</p></div>",
  "size": {
    "width": 3.5,
    "height": 2,
    "unit": "in"
  }
}

Note: For responsive web content, you may want to use the prefer_css_page_size parameter in conjunction with size to control how content is scaled to fit the page.
