How to Create a Custom 17x64-Inch Page for Printing in Excel
Question details
The user wants to set up and preview a custom 17-by-64-inch page layout for a poster in Excel, but the application restricts paper sizes based on installed printer drivers.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Designing and previewing a single large-format placard (17x64 inches) in Excel without having a physical large-format printer connected to the computer.
- Observed behavior
- Excel does not offer an option to manually enter a 17x64-inch custom page size because it strictly derives available paper sizes from the currently active printer driver, which typically only supports standard dimensions.
Verify if you have a PDF printer driver installed (such as Microsoft Print to PDF or Adobe PDF), as these virtual printers sometimes offer wider support for custom page dimensions.
Install a Virtual Large-Format Printer Driver
By installing a generic plotter driver on your system, you can trick Excel into allowing large custom page sizes like 17x64 inches.
Because Excel relies entirely on the active printer driver to populate the Page Setup size list, adding a driver for a large-format printer (even if you do not own the physical device) will unlock custom dimension capabilities.
Navigate to your Windows Settings, select 'Devices', and click on 'Printers & scanners'.
Click 'Add a printer or scanner'. Wait a moment, then select 'The printer that I want isn't listed' when it appears. Choose 'Add a local printer or network printer with manual settings' and click Next.
Choose an existing port (like FILE: or PORTPROMPT:). In the manufacturer list, select a brand known for plotters (like HP) and choose a large-format model (e.g., HP DesignJet). Complete the installation.
Open your Excel workbook. Go to File > Print and select your newly installed plotter from the printer dropdown. Then navigate to Page Layout > Size > More Paper Sizes, click 'Options' to open the printer properties, and define your custom 17x64 inch dimensions.

Use Dedicated Desktop Publishing Software
If manipulating Excel's printer drivers is not viable, use software naturally designed for custom canvas sizes.

While large-scale print dimensions rely on your computer's printer drivers regardless of the software, WPS Office provides a streamlined, highly compatible, and free alternative to Microsoft Office. It seamlessly opens your existing spreadsheets while offering built-in PDF conversion to make handling and sharing large formats easier.
- 1. Download and Install: Download WPS Office for free from the official website and follow the quick installation prompts.

Frequently Asked Questions
Why doesn't Excel let me enter custom paper dimensions?
Excel relies entirely on the printer driver currently selected on your computer to determine paper size options. If the active printer cannot physically handle a custom size, Excel will not allow you to enter it in the Page Setup menu.
Can I print a large Excel poster using standard letter paper?
Yes. While you cannot natively split a single massive page in Excel, you can check your printer's properties (File > Print > Printer Properties) for a 'Poster' or 'Tiling' print feature. This automatically divides a large design across multiple standard 8.5x11-inch pages that you can tape together.
How do I save a 17x64-inch Excel file to send to a print shop?
Once you have configured the 17x64-inch page using a virtual plotter driver, go to File > Save As, and choose 'PDF' from the file format dropdown. The resulting PDF will retain your custom dimensions and can be printed by any professional print shop.
