Create Custom Envelope Sizes via macOS Page Setup

Use the built-in macOS Page Setup menu within Word to manually define the exact dimensions and non-printable margins for your A2 or A7 envelopes.

Because specific envelope sizes might not be included natively in Microsoft Word for Mac, you can define them manually. This method leverages the macOS system-level print settings to ensure the custom dimensions are saved and recognized by your printer.

1
Open Page Setup

Open your document in Word for Mac. From the top Apple menu bar, click on File and select Page Setup.

Manage Custom Sizes

In the Page Setup dialog, click on the Paper Size dropdown menu and choose Manage Custom Sizes at the bottom of the list.

3
Add and Define Envelope Dimensions

Click the Plus (+) button to create a new profile. Double-click the new item to name it (e.g., 'A2 Envelope'). Enter the precise dimensions (A2 is 4.37" x 5.75"; A7 is 5.25" x 7.25").

4
Set Printer Margins

In the Non-Printable Area section, select your specific printer from the dropdown menu to apply its minimum hardware margins, or enter them manually.

Apply and Format

Click OK to save the custom size. Back in the main Page Setup window, ensure the new custom envelope size is selected, choose Landscape orientation if required by your printer's feed tray, and click OK.

Frequently Asked Questions

What are the exact dimensions for A2 and A7 envelopes?

An A2 envelope measures 4.375 x 5.75 inches, and an A7 envelope measures 5.25 x 7.25 inches. You will need these exact measurements when configuring your custom paper dimensions in the Page Setup menu.

Why does my printer reject the custom envelope size I created?

Your printer hardware may have mechanical limitations regarding the minimum paper size it can safely feed. Consult your printer's instruction manual to verify A2 or A7 support. Additionally, ensure the non-printable margins in your custom settings match the printer's hardware limitations.

Are custom envelope sizes saved permanently in Word for Mac?

Yes. When you create a custom size via File > Page Setup > Manage Custom Sizes, it is saved at the macOS system level. This means the custom A2 or A7 profile will remain available in the dropdown menu for future Word documents and even in other Mac applications.

How should I physically load the envelopes into my printer?

This depends entirely on your specific printer model's feed tray mechanism. Most home office printers require envelopes to be loaded vertically (short-edge first) and centered, but you should always refer to the embossed icon on your printer's input tray for the correct orientation and face-up/face-down requirements.
