Postcards for Artists, Events, and Business Promotion
Postcards are one of the most versatile print products available. Artists use them as mini prints, fan art cards, and booth-friendly impulse items. Small businesses use them for marketing handouts, direct mail, and promotional giveaways. Event organizers use postcards to advertise performances, fundraisers, grand openings, and special announcements.
Because postcards are compact, affordable, and easy to display, they work especially well when you need something that feels more substantial than a flyer but is still simple to distribute. They stack on a counter, slip into orders, hand out at events, and drop into mail campaigns — without the complexity or cost of a larger print product.
For Artists & Creators
Postcards are one of the top-selling product categories at Artist Alley tables — affordable to produce, easy to display upright in acrylic stands, and priced at an impulse-buy level that fans grab without overthinking. Mini prints, fan art cards, and character art cards move reliably at small local cons or major events. They also work as branded inserts in online orders, adding something physical to an otherwise digital shop experience.
For Small Businesses
Marketing postcards, direct mail pieces, service menus, coupons, and promotional giveaways. A well-designed 4×6 postcard in a direct mail campaign stands out from standard envelope mail. A 5.5×8.5 can carry enough content to serve as a compact service menu or offer piece. Postcards are among the most cost-effective physical marketing tools available — and customers actually keep the ones that look good.
For Events & Promoters
Event announcements, concert promotion, festival handouts, grand opening cards, and fundraiser invitations. The postcard format is perfect for events: compact enough to distribute at other venues, visually compelling enough to hold onto, and affordable enough to produce in the quantities that effective event promotion requires. The 6×11 oversized format in particular makes a striking event announcement that doesn't get lost in a stack.
Choose the Right Postcard Size
Different postcard sizes serve different goals. Smaller cards are excellent for merch tables, inserts, and quick giveaways, while larger cards create more impact for promotions, menus, announcements, and oversized marketing pieces. Here's a full breakdown of every size in the collection.
3×3 Mini Cards
Smallest format | Lowest cost per piece | Square
Small, affordable, and easy to include in any packaging. Perfect for artists adding value to orders or creating collectible mini print sets. At 3×3, the square format is immediately distinctive — it doesn't look like a standard card or flyer. Works beautifully for chibi art, character close-ups, and designs with bold, simple compositions that translate well to a compact square canvas.
Best for: Packaging inserts, collectible mini prints, merch add-ons, order thank-you cards, and Artist Alley impulse buys priced at $2–4.
4×6 Postcards
Most popular size | Standard postcard format | Mailable
The most common and recognized postcard size, 4x6 is what most people picture when they hear the word. Fits standard postcard racks and display stands. At 4×6, there's enough canvas for a strong visual, a compelling headline, and essential contact or event information on the back. Qualifies for standard USPS postcard postage rates when mailed without an envelope, making it the most cost-effective direct mail format in the collection.
Best for: Direct mail campaigns, event handouts, art cards, business promotions, and convention mini prints.
5×7 Cards
Most popular artist size | Standard frame-ready | Premium feel
The 5×7 is arguably the most popular size for Artist Alley print sales — big enough to showcase real detail in a character illustration or scenic piece, and sized to fit standard 5×7 frames that buyers already own. It feels more substantial than a 4×6 without crossing into poster territory. Artists price 5×7 cards at $8–15 and they move consistently across conventions, online shops, and market tables.
Best for: Premium art cards, character and fan art prints, invitations, announcements, and any print meant to be framed or displayed.
5.5×8.5 Postcards
Half-sheet format | More content room | Menu and promo friendly
More space for content and design than a 5×7, while staying compact enough for counter display and easy handout distribution. The half-sheet proportion works especially well for menus, detailed service listings, and event announcements that need to carry more information than a standard postcard can comfortably hold. A natural upgrade from the 4×6 for businesses that need their card to do more work.
Best for: Restaurant and service menus, event announcements, business promotions with detailed content, and artist prints that benefit from the landscape half-sheet proportion.
6×11 Postcards
Oversized format | Maximum visual impact | High-visibility marketing
Oversized and attention-grabbing — the 6×11 doesn't get lost in a stack of standard marketing materials. The wide horizontal format gives campaigns, events, and promotions a cinematic quality that smaller cards can't deliver. When this card lands in someone's mailbox or gets handed to them at an event, it commands attention through sheer scale. The highest-impact postcard format in the collection.
Best for: Event promotion, direct mail campaigns that need to stand out, oversized art prints, bold marketing pieces, and any use case where visual presence is the priority.

Card Stock Options
We offer multiple postcard stock options so you can match the finish to your artwork, brand, and use case. Choose from gloss, matte, and textured stocks across much of the collection, with select sizes also available in thicker 16pt and 18pt card stocks for extra durability and a more substantial feel in the hand.
Gloss Card Stock
A high-shine coated surface that produces brilliant, saturated color — ideal for bright colors, high-contrast designs, photography, and bold promotional graphics. The most popular stock choice for artist prints and promotional postcards if brighter colors are the priority. Colors print with maximum punch, and the finish catches light in a way that makes artwork genuinely pop on a display table.
Best for: Fan art prints, photography cards, event promos, and any design where vibrant color is the selling point.
Matte Card Stock
A smooth, elegant, non-reflective finish that reduces glare and reads as more refined than gloss. Colors are slightly softer on screen, but the overall presentation is sophisticated and gallery-appropriate. Also, the only postcard stock that's easy to write on — coated and gloss stocks repel most pen ink. Choose matte when your brand aesthetic calls for something quieter, or when buyers will be writing on the card.
Best for: Soft-palette illustration, photography with a film aesthetic, thank-you cards, and any design meant to feel editorial rather than promotional.
Textured Card Stock
A lightly textured surface that gives prints a tactile, fine-art quality. Especially appealing for artists who want their postcard prints to feel more premium and distinctive from the standard convention table fare. Buyers consistently notice and comment on textured stock in a way they don't with gloss or matte.
Best for: Artist prints, painterly illustration, premium postcards, and any design where the physical feel of the card is part of what's being sold.
16pt & 18pt Stocks
Thicker postcard stocks for mailing durability, premium handout applications, and any situation where the physical weight of the card communicates quality. A standard postcard on thin stock bends easily in a wallet or purse; a 16pt or 18pt card holds its shape and feels deliberately made. Available on select sizes — check individual product pages for thickness options.
Best for: Direct mail that needs to survive transit cleanly, premium business handouts, and artist prints where added weight reinforces the perceived value of the piece.
Popular Uses for Postcards
Because of their flexibility in size, stock, and price point, postcards serve a wider range of purposes than almost any other print product. Here's how different customers use them.
Art Prints & Artist Alley Cards
Mini prints and fan art cards are among the highest-volume sellers at any Artist Alley table. Affordable to produce, easy to rack upright in display stands, and priced as impulse buys — postcards can represent a significant portion of convention revenue even when larger prints are the centerpiece of the display. For artists, postcards can become an easy entry-level item that complements larger prints, bookmarks, stickers, and booth displays.
Direct Mail & Promotional Mailers
The 4×6 postcard qualifies for standard USPS postcard postage — making it one of the most affordable direct mail formats available. Larger sizes like 5.5×8.5 and 6×11 mail at First-Class letter rates and stand out more dramatically in a mailbox. Postcards used for direct mail should have the mailing panel (address block, postage area) on the back, with the full front surface dedicated to the visual impact that earns a second look.
Event Handouts & Promotion
Concert announcements, festival promotion, gallery openings, theater performances, fundraisers, and grand openings. Postcards placed at related venues — coffee shops, bookstores, music venues, art supply stores — reach exactly the audience most likely to be interested. A 6×11 oversized event card placed in a coffee shop card rack gets pulled out and kept in a way that a standard flyer rarely does.
Menus & Service Cards
Takeout menus, spa and salon service menus, and retail product cards on 5×7 or 5.5×8.5 stock. A menu card that looks and feels like a quality print piece reflects better on the business than a flimsy photocopied sheet. Leave them at the counter, slip them into delivery bags, or distribute to hotels and neighboring businesses.
Thank-You Cards & Order Inserts
A 4×6 or 5×7 thank-you card included in an online order adds a personal touch that customers remember and share. It's also a natural promotion vehicle — a QR code to your shop, a discount code for the next purchase, or a social media handle on the back turns a gesture of appreciation into a marketing touchpoint. Especially effective for Etsy sellers and small online shops building repeat buyer relationships.
Invitations & Announcements
Baby announcements, wedding save-the-dates, graduation announcements, and party invitations. The 5×7 size fits standard A7 envelopes and is the most common single-panel invitation format. The 4×6 works for save-the-dates and casual event invitations. Premium stocks — matte or textured — give invitation-style postcards the elevated feel that special occasions deserve.
Short Runs and Bulk Quantities
Not every customer needs thousands of postcards. Our postcard printing collection works well for both short-run orders and larger production needs. Order smaller quantities for test runs, convention prep, product inserts, or limited promotions — or scale up for direct mail, retail distribution, and event marketing. This flexibility is especially helpful for artists and small businesses that want professional print quality without overcommitting to large inventory.
Most postcards ship in 2–3 business days, making them a reliable option for upcoming events, marketing campaigns, convention prep, and product launches. Rush and expedited options are available for tighter timelines.

Postcard Printing FAQ
What postcard sizes do you offer?
We offer a wide range of postcard sizes including 3×3 mini cards, standard 4×6 postcards, 5×7 art cards, 5.5×8.5 half-sheet postcards, and 6×11 oversized promotional cards. Square card options are also available. Each size serves different use cases — see the size guide above for a full breakdown of which format fits which project.
What stock is best for postcards?
Gloss is the strongest choice for bright colors, vibrant artwork, and bold promotional graphics — it maximizes color saturation and visual impact. Matte offers a clean, non-reflective finish that's also writable — the right choice when your brand aesthetic is more refined or when buyers will write on the card. Textured stock is popular with artists who want their postcard prints to feel more premium and distinctive. Thicker 16pt and 18pt options are available on select products for added durability and a more substantial feel.
Are postcards good for artists?
Yes — postcards are one of the most reliable and profitable product categories for artists selling at conventions, online shops, and markets. They're affordable to produce, easy to display in acrylic stands, priced as impulse buys at $4–10 each, and can feature your strongest artwork in a format buyers can actually use. They also double as thank-you inserts for online orders, giving your Etsy or website customers something physical that reinforces your brand.
Can postcards be mailed?
Yes. The 4×6 postcard qualifies for standard USPS postcard postage rates — one of the most affordable direct mail formats available. Larger sizes (5×7, 5.5×8.5, 6×11) mail at First-Class letter rates. For any mailing application, design your back panel with a mailing area (address block, return address, postage zone) and keep the front panel as your full visual impression. Confirm current USPS rate requirements before a large campaign as postal regulations can change.
Do you check artwork before printing?
Yes. Our team reviews artwork before printing and will contact you if there are issues that need attention — low resolution, missing bleed, incorrect sizing, or other file setup problems. That extra review step helps catch common issues before your order goes into production, so you're not surprised by the result.
Can I order postcards in small quantities?
Yes. Our postcard collection is well-suited for short-run printing — ideal for events, Artist Alley tables, product inserts, and test runs without committing to a large inventory. Start small, see what sells and what resonates, and scale up on the designs that perform.
What file format and specs should I submit?
Submit print-ready PDF, high-quality JPG, or TIFF files at 300 DPI at your finished postcard dimensions. All postcards are printed in CMYK — design in CMYK for the most accurate color match. Add 0.125" bleed on all sides for full-bleed designs and keep important content at least 0.125" inside the trim edge. If you're unsure whether your file is set up correctly, submit it anyway — our team will review it and contact you if anything needs adjustment before printing begins.
