Postcard Printing Guide for Design, Paper and Mailing Tips
Pick the right stock and size, build a print-ready file in CMYK, follow the USPS mailing rules, and order in volume to drop the cost per card. Here is the full postcard playbook, start to mailbox.
For the best postcard printing, match the stock and size to the job: a 14pt or 16pt gloss card on a 4.25 by 6 inch layout hits the lowest USPS rate and prints color-rich. Build the file in CMYK at 300 DPI with a 0.125 inch bleed, keep the address block clear for the post office, and order in volume so the price per card drops on the mailing.
Quick tips
Quick tips for printing better postcards
Choose the stock and size before you design. A 14pt or 16pt gloss card at 4.25 by 6 inches prints color-rich and mails at the lowest USPS postcard rate. Build the file in CMYK at 300 DPI with a 0.125 inch bleed, and keep the lower-right of the back clear for the address and barcode. Order in volume and the price per card falls fast. 4OVER4.COM customers who plan the stock, size, and quantity up front get sharper cards for less.
Why postcard printing still wins for direct response
A postcard lands in the hand, not in a spam folder. There is no envelope to open and no inbox to ignore, so the offer is read the moment the mail is sorted. That is why a well-printed postcard still pulls response rates that most digital channels cannot match, especially for local businesses, real estate, and repeat-purchase offers.
The catch is that the card has to look and feel the part. A thin, dull print signals a discount, while a thick, sharp card on the right stock signals a brand worth trusting. This guide walks through the choices that make that difference: paper, size, design setup, USPS mailing rules, and the cost math that keeps a campaign profitable.
If you are running other print projects alongside your mail, our Online Designer handles color and bleed for you, and you can even learn how to fold a brochure for a matching leave-behind. Our full guide hub covers the rest of the print stack.
Choosing the right postcard paper and finish
Stock is the first decision because it sets both the feel and the cost. For most marketing postcards, a 14pt or 16pt gloss cover is the workhorse. It is rigid enough to survive the mail stream and glossy enough to make photos and color pop. Step up to an 18pt or thicker luxe stock when you want the card to feel premium the instant it is picked up.
Finish changes the whole personality of the card. A high-gloss UV coating deepens color and adds shine, a matte or soft touch finish reads as calm and upscale, and an uncoated stock is the one to pick when someone needs to write on the card. Specialty finishes like silk, kraft, and metallic give a brand a tactile signature that a screen can never reproduce.
If you are printing postcards alongside other 4OVER4.COM marketing materials printing, matching the stock and finish across the set keeps your brand consistent from the mailbox to the counter.
Postcard sizes and what each one is for
Size is where mailing cost and shelf appeal meet. The most common choices break down cleanly by job.
- 4.25 x 6 in qualifies for the lowest First-Class postcard rate and fits a clear headline, one image, and a single offer.
- 5 x 7 in gives the design more room to breathe and still mails affordably for invitations and announcements.
- 6 x 9 in and 6 x 11 in dominate the mailbox and are the go-to sizes for Every Door Direct Mail routes.
The larger the card, the more it costs to print and mail, so match the size to the job rather than defaulting to the biggest option. For a full breakdown, our postcard sizes and dimensions guide lists every standard size and its best use, and the EDDM postcard sizes guide covers what the route program allows.
Setting up a print-ready postcard file
A great postcard starts with a file the press can trust. Get these four things right and the print matches the screen.
- Work in CMYK color. Screens use RGB light, presses use CMYK ink, so convert to CMYK before you export or the vivid blues and greens shift.
- Design at 300 DPI. Anything lower prints soft and pixelated, no matter how good the art looks on a monitor.
- Add a 0.125 in bleed. Extend background color and imagery past every edge so the trim never leaves a white sliver.
- Respect the safe zone. Keep text and logos at least 0.125 in inside the trim line so nothing important gets cut.
If file setup is not your thing, 4OVER4.COM's Online Designer handles bleed, resolution, and color conversion automatically, and every order is checked by a real prepress team before it prints. Building a matching set? Our guides on how to make flyers, how to make envelopes, custom magnets, and how to clean rubber stamps use the same file rules.
USPS mailing specs that keep postage low
The post office reads a postcard by its layout, so a few rules decide whether you pay the standard rate or a surcharge. Get them right once and every card in the run mails clean.
Leave the address block clear. USPS needs the lower-right of the address side open for the delivery address and the barcode. Graphics that creep into that zone can slow delivery or trigger a nonmachinable fee.
Stay inside the postcard dimensions. To mail at the First-Class postcard rate, a card must fall within the USPS size limits. Go bigger and it mails as a letter or a flat at a higher rate. Our postcard mailing dimensions guide lists the exact minimums and maximums.
Place the stamp and indicia correctly. The upper-right corner is reserved for postage. For the full walkthrough on addressing and postage, see how to address a postcard and how to mail postcards.
Every Door Direct Mail without a mailing list
Every Door Direct Mail, or EDDM, is the shortcut to a full neighborhood. Instead of buying or renting a list, you pick postal routes on the USPS map and send a card to every address on them. It is built for local reach, so it is a favorite of restaurants, home services, and grand openings.
The trade is that EDDM requires an approved card size, typically a larger format like 6 x 9 or 6 x 11 inches, and the postage is charged per piece at a reduced rate. Because there is no list to manage, the setup is simpler and the cost per household is low, which makes it the most economical way to blanket an area.
Print your EDDM cards to spec with direct mail postcards from 4OVER4.COM, and use our EDDM postcard sizes guide to confirm the dimensions before you order.
Specialty postcards that get noticed
When a standard card is not enough, a specialty finish turns the mailbox into a moment. These are the formats that stop people mid-sort.
3D lenticular postcards shift and animate as the card tilts, so a single mailer holds motion in the hand. They are unforgettable for product launches and event invites. Start from a ready-made layout with the 3D lenticular postcard template or order the finished product as 3D lenticular postcards.
Black postcards print white and metallic inks on a deep black stock for a bold, high-contrast look. Grab the black postcard template to see how the layers stack. Browse the full range of ready designs in our blank templates library, and if you are in a hurry, same day printing can turn a rush campaign around fast.
What custom postcard printing actually costs
Postcard pricing comes down to four levers: quantity, size, stock, and finish. Quantity is the biggest one. The per-card cost falls sharply as the run grows, so a larger order is the simplest way to lower the price on a mail campaign.
Standard postcards at 4OVER4.COM start at $16.48, and a plain 14pt gloss card at a common mailing size is the most economical build. Upgrades like thicker stock, UV coating, silk, or metallic add cost per card but raise the perceived value, so weigh the finish against the audience and the offer.
The live price table further down this page shows real per-unit costs at each quantity straight from the postcard configurator, so you can see exactly where the bulk savings kick in before you order.
Mistakes that ruin a postcard mailing
Even a strong offer falls flat when the print or the mail setup is off. Avoid these and the campaign does its job.
Designing in RGB. Colors that glow on screen print dull once the press converts them. Build and export in CMYK so the card matches your proof.
Skipping the bleed. Art that stops at the edge risks a white sliver after trimming. Always extend background color 0.125 inch past every side.
Crowding the address zone. Graphics or text in the USPS clear area slow delivery and can add a surcharge. Keep the lower-right of the back open.
Choosing size last. Picking a size after the design can push the card into a higher postage bracket. Decide the mailing size first, then design to it.
Ordering too few. Small runs carry a high per-card cost. Because postcard pricing drops with volume, a slightly larger order often costs little more and reaches far more people. 4OVER4.COM prints across 60+ paper types so you can scale up without losing the look.

Wally explains postcard printing

Common Questions
Common questions about postcard printing
What size postcard is best for mailing?
A 4.25 by 6 inch card is the sweet spot for most campaigns because it qualifies for the lower USPS First-Class postcard rate while still leaving room for a headline, offer, and image. If you want more space, a 6 by 9 or 6 by 11 inch card stands out in the mailbox and works well for Every Door Direct Mail routes. Check our postcard mailing dimensions guide before you finalize the layout.
What paper stock should I use for postcards?
For most marketing postcards, a 14pt or 16pt gloss cover gives you rich color, sharp photos, and a sturdy card that survives the mail stream. Choose an uncoated matte or a kraft stock when recipients need to write on the card, such as appointment reminders or handwritten notes. Premium options like silk, soft touch, and metallic add a tactile finish that signals a higher-end brand.
How do I set up a print-ready postcard file?
Build the file in CMYK color at 300 DPI, add a 0.125 inch bleed on every side, and keep important text and logos at least 0.125 inch inside the trim line. Export a flattened PDF with the profile embedded. If you would rather skip the setup, the Online Designer handles bleed, resolution, and color conversion for you, and every order is checked by a real prepress team.
Do I need to leave space for the address on a postcard?
Yes. USPS needs the lower-right portion of the address side left clear for the delivery address and the barcode. Crowding that zone with graphics can slow delivery or trigger a nonmachinable surcharge. Our postcard addressing guide shows the exact clear zone and placement rules so your mailing goes out at the standard rate.
How much do custom postcards cost?
Postcard pricing scales with quantity, size, stock, and finish. Standard postcards at 4OVER4.COM start at $16.48, and the price per card drops sharply as the run gets larger, which is why bulk orders are the cheapest way to reach a big list. Use the live price table on this page to see real per-unit costs at each quantity before you order.
What is EDDM and how does it lower mailing cost?
Every Door Direct Mail lets you send postcards to every address on a chosen postal route without buying or renting a mailing list. You pick the routes on the USPS map, print the cards to an approved EDDM size, and pay a reduced per-piece postage rate. It is the most cost-effective way to blanket a neighborhood, and our EDDM sizes guide covers the exact dimensions the program allows.
