Premium 4x6 Postcards for Artists, Marketers, and Mailers
Printkeg's 4x6 postcards are the most popular size we print, and for good reason. The classic postcard proportions are hand-sized, easy to distribute, inexpensive to mail at USPS postcard rates, and large enough to showcase real artwork without feeling oversized. We print them full-color and full-bleed on three archival, opaque cardstocks built to hold detail, color, and texture from the first piece to the last.
Most of our 4x6 customers aren't running direct mail campaigns. They're artists, illustrators, and photographers selling mini prints at conventions, packaging thank-you cards with online orders, and producing affordable wall-worthy reproductions for Etsy shops and artist alleys. That use case shaped the way we built this product: gallery-grade cardstocks, sharp digital press color, and short-run pricing that doesn't punish you for ordering 50 instead of 5,000.
Best Uses for 4x6 Postcards
- Artist mini prints: Convention sales, artist alley tables, Etsy listings, and gallery shop inventory
- Order inserts and thank-you cards: Branded packaging fillers for online shops, subscription boxes, and handmade goods
- Photography proofs and samples: Affordable client previews, session keepsakes, and portfolio handouts
- Direct mail campaigns: Real estate farming, local service promotions, restaurant menus, and event announcements
- Save the dates and announcements: Weddings, parties, grand openings, and milestone celebrations
- Business and networking cards: Oversized alternatives to standard business cards with room for portfolio imagery
- Fundraising and nonprofit appeals: Donor outreach, event invitations, and campaign updates
Three Archival Cardstocks
Gloss Cardstock (110# Cover)
A heavyweight satin-gloss stock with a light reflective sheen that brings out vibrant, saturated color. The smooth coated surface is ideal for photography, illustration with bold color palettes, and any design where punch and contrast matter. The 110# weight gives the card a substantial, professional hand-feel that holds up to mailing and repeat handling.
Matte Cardstock (100# Cover)
A luxurious, uncoated stock favored by fine artists and photographers who want a softer, more sophisticated finish. Colors render with depth and subtlety rather than gloss-sheen pop, making it the right choice for muted palettes, watercolor reproductions, black-and-white photography, and editorial design. The uncoated surface is also fully writable, which makes it a strong pick for direct mail with handwritten notes or signed art cards.
Textured Felt Cardstock (100# Cover)
Our premium specialty stock with a tactile felt finish that adds real texture and authenticity to fine art reproductions. The textured surface gives prints a gallery-grade quality that elevates artwork beyond what flat coated stocks can deliver. Especially well-suited for watercolor, pastel, mixed media, and illustration work where the paper itself becomes part of the artistic experience.
