How Do You Write With Index Cards?

Quick Fix: Print index cards straight from Word by setting the paper size to 3×5 inches, adjusting margins to 0.25 inches, and using the Labels feature under Mailings → Labels → Options → Index Card.

What’s happening here?

You need to convert a digital draft or notes into physical index cards for outlining a novel, screenplay, or study guide.

Honestly, this is the simplest way to go from typing to tactile planning. Design your content in a word processor and print it directly—but margins, orientation, and printer alignment often create formatting headaches. As of 2026, Microsoft Word, Google Docs, and dedicated apps like NoteDex support index card templates and direct printing, yet setup still trips up plenty of users.

How do you actually print index cards from Microsoft Word?

Set up a custom 3×5 page size, adjust margins, and print using the Labels feature.

Method 1: Print from Microsoft Word (Windows/macOS) — 3×5 Cards

Open a new Word document. Head to Layout → Size → More Paper Sizes.
In the Paper Size dialog, pick Custom Size. Type in 3 inches wide and 5 inches tall. Name it “3×5 Index Card” and hit Save.
Set all margins to 0.25 inches: Layout → Margins → Custom Margins → enter 0.25 for top, bottom, left, right. Click OK.
Now go to Mailings → Labels. In the Labels window, click Options.
Choose Label vendors → Avery US Letter. Scroll down and select Avery 5388 (the 3×5 index card option). Click OK → OK.
Type your content. Hit Ctrl + Enter after each card to jump to the next one.
Make sure your printer is set as default. Go to File → Print. In printer settings, set the paper source to manual feed if needed. Load index cards face-up in the tray. Print a test page on plain paper first to check alignment.

Method 2: Print from Google Docs (3×5 or 4×6)

Open Google Docs. Change the page size: File → Page setup. Enter 3 inches wide and 5 inches tall. Click OK.
Set all margins to 0.25 inches: File → Page setup → Margins → set 0.25. Click OK.
Go to File → Print. In the printer settings, choose Paper size → Manage custom sizes. Add a new custom size: 3" x 5". Save it.
In Google Cloud Print or your local printer dialog, select your custom size and feed a single index card into the manual tray.
Print one card as a test. If the text is off-center, tweak the alignment in printer settings.

Method 3: Use a dedicated index card app (NoteDex)

Download NoteDex from the Microsoft Store (Windows), Mac App Store, or iOS/Android.
Open the app and create a new deck. Each card is 3×5 by default—no setup needed.
Tap a card to add scene summaries, character names, or study terms. Flip the Cloud Sync toggle to keep everything updated across devices.
Export to PDF or print directly via File → Print Deck → Print Setup. Pick your printer and paper size.

What should you do if the printing still looks wrong?

Check printer settings, try portrait mode, and adjust font size and spacing.

Misaligned text or cropping? Confirm your printer supports manual feed and that the card is loaded correctly. Even for 3×5 cards, try printing in portrait mode—it often fixes alignment issues.
Font too large? Stick to 10–12pt fonts like Calibri or Arial. Reduce line spacing to 1.0 to keep things tidy.
App won’t let you pick card sizes? Create a custom paper size in your OS print dialog. On macOS, go to System Preferences → Printers & Scanners → Open Print Queue → Options & Supplies → Paper Size → Manage Custom Sizes.

How can you avoid printing problems in the future?

Set up reusable templates and keep a reference card handy.

In Word, save your 3×5 setup as a template: File → Save As → Word Template (.dotx). Reuse it without reconfiguring margins or size every time.
For Google Docs, save a template in Drive with pre-set dimensions and margins—just open it, edit, and print.
Keep a stack of index cards in your desk with a sample printed card taped to the box. That way, you’ll always load them the right way.
Back up digital decks using cloud sync in apps like NoteDex so you never lose your outlines.

As of 2026, standard 3×5 index cards still measure 76.2 × 127.0 mm, according to ISO. Before you print a whole stack, double-check that your printer handles cardstock without jamming.
