Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Set PDF layout in the request options documented by the API that generates your PDF. Choose either a standard paper preset or explicit page dimensions, set the margins in that provider’s accepted format, and configure orientation using its own field. Then check which setting wins if request options conflict with CSS @page, and account for headers and footers when diagnosing clipping.
There is no universal PDF-layout request schema: Cloudflare, Adobe, PDF.co, and PDFCrowd document different controls and conventions. The examples below show how to choose and verify a provider-specific configuration without treating one API’s field names as portable to another.
Choose the page size and orientation together
Start by deciding what the finished document must fit: a standard page format, or a custom width and height. Then confirm how the API represents that choice. Some APIs offer named presets; others expose dimensions; some provide both. The dimensions, units, field types, and precedence rules are implementation details of the selected service, not properties of PDF generation in general.
Orientation is related to dimensions, but it is not safe to assume that changing orientation automatically swaps a custom width and height. Check the API’s behavior for the exact combination you plan to send. If a document already includes CSS page rules, also find out whether the request or the CSS controls the final page size.

| Provider reference | Documented layout pattern | Important qualification |
|---|---|---|
| Cloudflare Browser Rendering | format for named choices; width and height for dimensions; boolean landscape; a margin object with top, right, bottom, and left fields. |
Cloudflare says a supplied format takes priority over width and height. It also documents preferCSSPageSize for giving CSS page size priority over other size declarations. |
| Adobe PDF Services | An HTML-to-PDF example uses a pageLayout object with pageWidth and pageHeight. |
Consult the API reference for the request schema and units for the endpoint and implementation language you use. |
| PDF.co | The PDF-from-URL reference lists paperSize, orientation, and margins. It describes standard page names and custom width-and-height strings, with units including px, mm, cm, and in. |
The referenced page was crawled about 1.3 years before September 29, 2026; verify the live documentation before copying its schema. It documents Portrait and Landscape orientation values. |
| PDFCrowd | Its layout model includes page dimensions and orientation, margins, header and footer heights, and content area. Its API lists controls for page size, width, height, orientation, individual margins, and no-margin behavior. | These controls and method names are specific to PDFCrowd; use them as a layout model, not as field names for another API. |
Preset or custom dimensions?
Use a named preset when the document needs a recognized paper format and the provider supports that format. Use custom dimensions when the output must match a specific page or canvas size. Confirm the accepted preset names and whether custom values are numeric or strings. Do not infer units from the number alone: a value such as 210 is ambiguous unless the API documents its unit.
Portrait or landscape?
Cloudflare’s documented control is a boolean landscape; PDF.co documents an orientation value with Portrait and Landscape options. These are distinct request shapes. With custom dimensions, check whether the provider expects you to supply the dimensions in the desired order, set an orientation field, or do both. The available references do not establish one cross-provider rule for resolving those settings together.
Set margins without clipping content
Margins reduce the space available to the page content. For a page with width W and height H, the nominal content area is the page area remaining after left and right margins are deducted from the width, and top and bottom margins from the height. Headers and footers can consume additional space depending on the renderer’s layout model.

Cloudflare documents a margin object with separate top, right, bottom, and left fields. PDF.co lists a margins option, while PDFCrowd exposes controls for individual margins as well as header and footer heights. Do not transfer an object shape, field name, or unit from one service into another service’s request.
Recommended Free Tools
- Check whether margins are required, optional, or replaced by a no-margin option.
- Confirm the unit and value type for each margin.
- Determine whether headers and footers are inside the margin region or take space in addition to it.
- Inspect long pages and edge content after rendering; text, tables, or fixed-position elements close to a page edge are common places to notice a layout conflict.
Resolve conflicts between API settings and CSS
HTML-to-PDF renderers may receive page-size instructions from both the API request and the document’s CSS. The precedence rule is provider-specific. Cloudflare documents the preferCSSPageSize option as giving CSS @page size priority over other size declarations. That is the meaning of Cloudflare’s option, not a general rule for every PDF renderer.
When the resulting paper size is unexpected, identify every place that might specify it: named format, explicit width and height, orientation, and CSS @page. Then consult the provider’s precedence documentation and remove or align competing settings. Avoid setting contradictory values and hoping the renderer will choose the intended one.

Implement the request using your provider’s schema
The following are documented field patterns, not complete API requests. They omit endpoint URLs, authentication, required wrapper objects, and other request fields because those details depend on the selected endpoint and implementation language. Use the provider’s current API reference to turn the relevant pattern into a request you can run.
- Cloudflare: choose a documented
formator usewidthandheight; add the documentedlandscapeandmarginfields as needed. If CSS page size should take priority, check thepreferCSSPageSizeoption. Remember that a suppliedformattakes priority overwidthandheight. - Adobe PDF Services: configure
pageLayout.pageWidthandpageLayout.pageHeightusing the units and schema documented for the HTML-to-PDF endpoint and language you are implementing. - PDF.co: consult the live PDF-from-URL reference for the current accepted values and request structure for
paperSize,orientation, andmargins. Its documentation describes standard page names and custom dimension strings in px, mm, cm, or in. - PDFCrowd: use its own documented controls for page size, width, height, orientation, margins, and header or footer layout; do not copy those method names into another provider’s integration.
A verification sequence
- Identify the API endpoint and the document input type: HTML, URL, or another supported input.
- Choose a named page format or the explicit dimensions supported by that endpoint.
- Set orientation using the provider’s documented value or field, and confirm its interaction with custom dimensions.
- Set each margin using the provider’s accepted structure and unit. Check header and footer behavior separately.
- Check whether CSS
@pagecan override request-level settings and configure precedence deliberately. - Generate a sample and inspect the PDF’s page dimensions, orientation, margins, and edge content in a PDF viewer or with your normal PDF validation workflow.
Troubleshoot unexpected page layout
The PDF has the wrong paper size
Look for conflicting format and dimensions first. In Cloudflare, a supplied format takes priority over width and height. If CSS page-size rules are present, check whether the API offers a precedence option; Cloudflare’s preferCSSPageSize is one documented example. Do not assume another provider behaves the same way.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThe page is landscape but content is clipped
Check the actual width and height used by the renderer, not just the orientation flag. Confirm whether custom dimensions should be supplied in landscape order and whether margins, headers, or footers reduce the available content area. Inspect a rendered page for content extending beyond the usable area.

Margins appear ignored or are much larger than expected
Verify the field name, object structure, unit, and value type against the selected API’s documentation. Also check whether a no-margin setting or CSS page rule is active. PDFCrowd’s layout description is a useful reminder that margin space and header or footer height can interact, but its controls do not establish how another renderer calculates content space.
CSS and request settings disagree
Make the desired source of truth explicit. If the provider documents a CSS-priority option, use it only when that is the intended behavior. Otherwise, align the CSS and request settings or remove one of the conflicting declarations, then render again.
A request example from an older page does not work
Confirm that the endpoint, field names, allowed values, units, and nesting are current for the API version you call. This is particularly important when adapting PDF.co’s referenced PDF-from-URL example, which was crawled well before September 29, 2026.

Performance, reliability, and cost considerations
The cited layout references establish configuration patterns, not a performance or price ranking. They do not provide a basis for claiming that a particular paper-size or orientation choice renders faster, or that one provider is cheaper for a given document. Compare current provider pricing and operational guarantees directly before selecting a service.
For reliability, validate the output rather than assuming a successful API response means the layout is correct. Keep a small representative document with long content, headers or footers if used, and elements near page edges. Re-render it when changing the provider, request schema, CSS page rules, or layout settings. The references do not establish identical rendering behavior across services, so treat a provider change as a layout change that needs verification.
Or skip the browser setup
If your goal is to render a web page as a clean capture or PDF without operating a browser yourself, ScreenshotNeo provides a website screenshot API and MCP server. Its PDF options include paper size, margins, landscape orientation, and page ranges; consult the API documentation for the current PDF request syntax. The one-call example below returns a WebP screenshot of the target URL; it is an image capture, not a PDF-layout request.

Frequently Asked Questions
Can I use the same PDF layout parameters when switching providers?
No. Field names, request structures, units, and precedence rules vary. Map each setting to the new provider’s current API reference and validate a generated PDF.
Do the cited references establish which API is fastest or cheapest?
No. They describe layout controls, not comparable performance measurements or pricing.
