How to Set a Custom Paper Size for a Printer on Windows [HP, Canon, Brother, Epson]

Have you ever tried printing a document, photo, label, or envelope only to find that your printer doesn’t support the paper size you need? This is a common problem when printing anything other than standard Letter or A4 paper. The good news is that you can often create a custom paper size in Windows 11 or Windows 10 and use it with compatible HP, Canon, Brother, and Epson printers.

A custom paper size lets you specify the exact width and height of your paper. For example, you might need a small card, a long banner, a custom-sized photo, or a label sheet. Once you configure the correct dimensions, you can select that size in your printer settings and, where supported, in your application’s print dialog.

However, the process can vary depending on your printer model and driver. Some printers let you create custom sizes directly in their printing preferences, while others require you to add a form through Windows printer server properties.

In this guide, you’ll learn how to create, select, and troubleshoot custom paper sizes on Windows, with instructions for HP, Canon, Brother, and Epson printers.

Set Custom Paper Size for Printer on Windows [HP, Canon, Brother, Epson]

To set a custom paper size in Windows, open Settings, go to Printers & scanners, select your printer, and open its Printing preferences. Look for Paper Size, User Defined, Custom Size, or a similar option. Enter the paper’s width and height, save the settings, and select the new size before printing.

If your printer driver doesn’t provide a custom size option, you can try creating a custom paper form through Windows Print Server Properties. 

Keep in mind that your printer must support the requested dimensions, paper type, and feed method.

Step 1: Measure Your Paper and Check Printer Compatibility

Before changing any settings, measure the paper you want to use. This helps you enter the correct dimensions and avoid printing problems.

Use a ruler to measure the paper’s width and height. For example, if you’re printing on paper that measures 5 by 7 inches, enter a width of 5 inches and a height of 7 inches. If your driver uses millimeters, the equivalent dimensions are approximately 127 by 178 mm.

Next, check your printer’s specifications. Every printer has minimum and maximum supported paper dimensions. Some models also limit custom sizes when you use the rear feed, automatic document feeder, duplex printing, or a particular paper type.

Visit your printer manufacturer’s official support website and search for your exact model number. Review its supported paper sizes and loading instructions.

This step matters because creating a custom size in Windows doesn’t automatically make an unsupported paper size printable. If your dimensions fall outside the printer’s supported range, the driver may reject them or the printer may feed the paper incorrectly.

Step 2: Open Your Printer’s Printing Preferences

The next step is to access the settings for your installed printer. These settings control paper size, orientation, print quality, and other printing options.

Press Windows + I to open Settings. In Windows 11, select Bluetooth & devices > Printers & scanners. In Windows 10, open Devices > Printers & scanners.

Select your HP, Canon, Brother, or Epson printer from the list. Depending on your Windows version, click Printing preferences or open the printer’s management options to find it.

A separate printer preferences window should appear. The available tabs depend on your printer and driver, but you may see options such as Paper/Quality, Page Setup, Basic, Main, or Advanced.

Look for a setting labeled Paper Size, Document Size, or something similar. Open its dropdown menu and check whether a custom size option is available.

If you see Custom, User Defined, or Manage Custom Sizes, select it and continue to the next step.

If you don’t see one of these options, don’t worry. Your printer may require a different driver or the Windows custom form method described later in this guide.

Step 3: Create a Custom Paper Size in Your Printer Driver

Once you locate the paper size settings, you can enter your own dimensions.

Select the custom size option in the printer preferences window. Depending on the manufacturer, a separate dialog may open where you can name the paper size and enter its measurements.

For example, you could name the size Custom Photo 5×7 and enter a width of 5 inches and a height of 7 inches. If the driver uses millimeters, enter the equivalent measurements instead.

Check whether the dialog displays width and height separately or uses a portrait-oriented format. Some drivers change the displayed dimensions when you switch between portrait and landscape orientation.

After entering the dimensions, click Save, OK, Add, or the equivalent option shown in your driver. The new size should appear in the available paper size list.

If the driver displays a warning about unsupported dimensions, review your measurements and check your printer’s specifications. Don’t enter smaller or larger values just to bypass the warning.

Once the custom size has been saved, select it as the paper size for your print job. You may also need to select the appropriate paper type and paper source.

Set a Custom Paper Size for an HP Printer

HP printers can offer custom paper size settings through the HP printer driver, although the exact options vary by model and driver version.

Open Settings > Bluetooth & devices > Printers & scanners in Windows 11, or Settings > Devices > Printers & scanners in Windows 10. Select your HP printer and open Printing preferences.

Look for the Paper/Quality or Advanced tab. If your driver supports custom dimensions, select Custom, Custom Paper Size, or a similar option.

Enter a descriptive name and specify the width and height of your paper. Save the new size, then select it from the paper size menu.

If the custom size option is missing, check whether you’re using the correct HP driver for your printer. A generic driver may expose fewer settings than the manufacturer’s full driver package.

You can download the appropriate software from HP’s official support website by searching for your printer model. Install the compatible driver, restart your computer if necessary, and check the printing preferences again.

Remember to load the paper in the tray recommended by HP for your particular model. Some HP printers support custom sizes only through specific trays or paper paths.

Set a Custom Paper Size for Canon, Brother, and Epson Printers

Canon Printers

Canon printers commonly provide a Page Setup tab in their driver preferences. Open your Canon printer’s Printing preferences and select the Page Setup tab.

Look for Page Size and select Custom Size or Custom Paper Size, if available. Enter a name, width, and height, then save the settings.

Select the new size before printing. If the option is unavailable, check Canon’s official support page for your model and install the appropriate driver.

Brother Printers

Brother printers may offer a Basic tab or a paper size dropdown in the printer driver. Open Printing preferences and review the available paper size options.

If your driver supports a custom size, select the relevant custom or user-defined option and enter the dimensions. Save the settings and select the new size for your document.

If you can’t find the option, consult the manual for your exact Brother printer. Custom paper support varies between models, and some printers accept only specified paper sizes.

Epson Printers

Epson drivers commonly include a User Defined option in the paper size menu. Open your Epson printer’s Printing preferences and look for the Main or Page Layout tab.

Select User Defined, enter a name, and specify the paper width and height. Confirm the settings and return to the main preferences window.

Select the new paper size and check the paper source before printing. If your Epson driver doesn’t show User Defined, check the manufacturer’s documentation for supported custom dimensions and driver requirements.

Create a Custom Paper Form Through Windows

If your printer driver doesn’t offer a custom size option, Windows may let you create a custom paper form through Print Server Properties. This method is useful when the driver supports Windows-defined forms.

Open Control Panel from the Start menu. Change View by to Large icons or Small icons, then select Devices and Printers if that page is available on your Windows installation.

In the Devices and Printers window, select a printer and look for Print Server Properties in the toolbar. On some Windows versions, you may need to open the printer list or access this option through the related printer settings.

In Print Server Properties, open the Forms tab. Check the option labeled Create a new form.

Enter a name for your custom paper size. Specify the width and height, along with the margins if Windows asks for them. Make sure the measurements fall within the supported range of your printer.

Click Save Form, then close the dialog.

Return to your printer’s Printing preferences and check whether the new form appears in the paper size list. If it doesn’t appear, your printer driver may not support that form, or the printer may require a manufacturer-specific custom size setting.

Creating a Windows form does not override the physical limits of your printer. The printer driver must recognize and support the dimensions before it can use them.

Select the Custom Paper Size in Your Application

Creating a custom size is only part of the process. You must also select it in the application you’re using to print.

Open your document in Microsoft Word, a PDF reader, a photo editor, or another printing application. Open File > Print and select the correct printer.

Look for Paper Size, Page Setup, or Printer Properties. Select the custom size you created. If the application has its own page size settings, make sure they match the paper dimensions configured in the printer driver.

For example, if you created a 5-by-7-inch paper size, the document page should also be configured for those dimensions if you want the content to fit the page correctly.

Check the print preview before sending the job. Confirm that the content isn’t cut off and that the orientation is correct.

If the custom size appears in printer preferences but not in the application, close and reopen the application. Some programs load paper size options when they start.

Print a Test Page and Troubleshoot Common Problems

Before printing a large batch, print one test page. This lets you check the alignment, margins, paper feed, and overall print quality without wasting supplies.

If the printer reports a paper size mismatch, confirm that the size selected in the application matches the size selected in the printer driver. Also check that the paper is loaded correctly and that the tray guides fit the paper snugly without bending it.

If the custom size is missing, reopen Printing preferences and check whether the size was saved. If necessary, create it again using the manufacturer’s supported method.

If the page prints with cut-off content, review the document’s page dimensions and margins. Some printers have nonprintable areas near the edges, so borderless printing may not be available for every custom size.

If the printer refuses to feed the paper, check the supported paper dimensions, weight, type, and tray restrictions in the manual.

FAQs

1. Can I set a custom paper size in Windows 11 and Windows 10?

Yes. You can often create a custom paper size through your printer driver’s Printing preferences. If the driver supports Windows-defined forms, you can also try Print Server Properties.

2. Why is the custom paper size option missing?

The option may be unavailable because of the installed driver, printer model, or paper feed method. Install the correct manufacturer-supported driver and check the printer’s specifications.

3. Can I use the same custom paper size for HP, Canon, Brother, and Epson?

The general process is similar, but the names and locations of settings differ. HP may use Custom Paper Size, Canon may use Custom Size, Brother may provide a user-defined option, and Epson commonly uses User Defined. Availability depends on the model and driver.

4. Why does my printer keep switching back to Letter or A4?

Your application, printer driver, or saved printing preferences may be overriding the custom size. Check the paper size in both the document settings and printer properties before printing.

5. Can I print any paper size after creating a custom form?

No. A custom form only defines the dimensions in Windows. Your printer must physically support the paper size, weight, type, and feed method.

Summary

Setting a custom paper size in Windows is usually straightforward once you know where your printer driver stores its paper settings. Start by checking your printer’s supported dimensions, open Printing preferences, and look for a custom or user-defined paper size option.

For HP, Canon, Brother, and Epson printers, the exact steps vary by model. If the driver doesn’t provide a custom size option, try creating a form through Windows Print Server Properties, provided your driver supports it.

Finally, select the custom size in your printing application, confirm the page layout, and print a test page.
