A custom postcard is a versatile, high-impact marketing tool for Omaha small businesses, restaurants, real estate agents, and local service providers. Whether you’re printing pizza specials, baby announcements, Valentine's Day event invites, or real estate listings, a well-designed postcard can increase both sales and brand awareness across the Omaha metro area. To start designing, you’ll first need to find postcard dimensions that best match your advertising needs. Your postcard size will determine multiple factors: what information you share, how detailed your layout can be, your postage costs, and which distribution method you choose.
Design-wise, postcard dimensions dictate how detailed your layout will be. You can choose between horizontal and vertical orientations for rectangular postcards, as well as single or double-sided printing to give you extra space for coupons, QR codes, and business details. If you’re planning on mailing postcards to customers in Omaha, your design needs dedicated space for postage stamps or indicia (prepaid postage markings). Check out USPS's design requirements to ensure your postcards qualify for First-Class or Marketing Mail rates.
Standard Postcard Size (4" x 6")
When most people think of a traditional postcard, they picture a 4" x 6" postcard. This size is spacious enough for your core marketing information while remaining cost-effective to print and mail. It’s ideal for grand opening invitations, seasonal promotions, thank you notes, and brand awareness cards. A 4" x 6" card qualifies for the lowest USPS First-Class Postcard postage rate.
- 4" x 6": The traditional standard size for cost-effective mailers, invites, and promotional handouts.
Small Postcard Sizes
Share short thank-you notes, appointment reminders, or concise marketing messages on small postcard prints. Ideal for promotions with minimal text, small postcards are compact, economical, and memorable.
- 2" x 4": Compact bookmark-style postcard format for short vouchers and event passes.
- 3" x 5": Classic index-card size ideal for simple inserts and recipe cards.
Large Postcard Sizes
When you’ve invested time into an eye-catching design, large postcard dimensions give your artwork maximum room to breathe. Larger cards stand out dramatically in a stack of mail compared to standard letters. Extra-large postcards can double as mini menu flyers, art prints, real estate feature sheets, or counter displays.
- 5" x 7": Premium invite size with ample room for high-res imagery and detailed product copy.
- 6" x 9": High-visibility jumbo mailer size popular for real estate listings and grand openings.
- 8" x 10": Oversized poster-card format for comprehensive menus and promotional displays.
Square Postcards
Step outside the box with a custom square postcard. Square cards are popular among artists, photographers, boutiques, and modern brands in Omaha looking for an unconventional visual shape. They provide a balanced frame for QR codes linking directly to online menus, portfolios, or booking pages.
- 3" x 3": Modern micro-card for box inserts and retail tag cards.
- 4" x 4": Balanced square format perfect for Instagram-style photo cards and QR codes.
- 6" x 6": Statement jumbo square card that commands immediate attention in mailboxes.
What Postcard Sizes Can You Mail via USPS?
USPS requires postcards to be rectangular (round or custom shape postcards must be mailed inside an envelope). For the First-Class Postcard Rate, the minimum size is 3.5" x 5" and the maximum size is 4.25" x 6". Larger rectangular postcards (like 5" x 7" or 6" x 9") are mailer-friendly but ship under First-Class Letter or Commercial Standard rates.
- 3.5" x 8.5" and 4" x 9": Rack card dimensions suitable for direct mail or brochure displays.
- 4.25" x 6" and 4.5" x 6.5": Standard First-Class compliant mailer sizes.
- 5" x 7" and 5.5" x 8.5": Popular medium-jumbo direct mail sizes.
- 6" x 8", 6" x 9", 6" x 11", and 8" x 10": Jumbo mailers for maximum impact across Omaha neighborhood carrier routes.
EDDM (Every Door Direct Mail) Postcard Requirements
Every Door Direct Mail® (EDDM®) allows Omaha businesses to target entire postal carrier routes without purchasing a mailing list. To qualify for EDDM rates, postcards must meet specific dimension guidelines (at least one dimension greater than 10.5" long OR greater than 6.125" high).
- 4" x 11", 4.25" x 11", and 4.5" x 11": Popular panoramic EDDM mailer formats.
- 6.5" x 8", 6.5" x 9", and 6.5" x 12": High-impact oversized EDDM postcard sizes.
- 8" x 10", 8.5" x 11", 9" x 11", and 9" x 12": Jumbo EDDM sizes for full-page menus and coupon sheets.
Postcard Design & Paper Stock Tips
Once you’ve selected your postcard dimensions, build your artwork with clear hierarchy. Use bold typography for your primary headline, high-resolution visuals, and a compelling call-to-action (like a discount code or phone number). Always account for full bleed (0.125" beyond trim lines) and keep critical text within safe safety margins.
