Print collateral sizes
Print collateral comes in standard sizes that vary by product type and region. Getting the dimensions right — including bleed, safe zones, and the correct DPI — is essential for professional print results.
All pixel dimensions below are at 300 DPI, the standard for high-quality printing. Remember to add 3mm (0.125") bleed on all sides and use CMYK color mode when preparing files for professional print production.

Business Card1050×600px
The standard US business card is 3.5×2 inches (88.9×50.8mm). At 300 DPI, that's 1050×600 pixels. Business cards are one of the most printed items in the world — getting the dimensions right prevents your design from being cropped or misaligned during production.
The US standard business card (3.5×2 inches) is the most common size in North America. International standards differ: the European/UK standard is 85×55mm (3.35×2.17"), Japan uses 91×55mm (3.58×2.17"), and Australia uses 90×55mm (3.54×2.17"). If you're designing for international use, check the target country's convention.

Best practices
- •Design at 1050×600px (300 DPI) with 3mm bleed on all sides (1125×675px total with bleed).
- •Keep text and logos at least 5mm from the trim edge to avoid cropping.
- •Use CMYK color mode and export as PDF/X-1a for best print results.
Postcard1800×1200px
The standard US postcard is 6×4 inches (152.4×101.6mm). At 300 DPI, that's 1800×1200 pixels. This is the most common mailable postcard size and qualifies for USPS First-Class postcard rates, which are cheaper than letter rates.
The 6×4 inch postcard is the most common size in the US and qualifies for the cheapest USPS mailing rate (First-Class postcards). USPS requires postcards to be between 3.5×5 inches (minimum) and 4.25×6 inches (maximum) for postcard rates. Anything larger ships at letter rates.

- •Keep within 3.5×5" to 4.25×6" to qualify for USPS postcard rates (cheaper than letter rates).
- •Reserve the right half of the back for address and postage — USPS requirement for mailable postcards.
Flyer2550×3300px
The most common flyer size is 8.5×11 inches (US Letter / A4). At 300 DPI, that's 2550×3300 pixels. Half-letter flyers (5.5×8.5 inches) are also popular for handouts. Flyers are single-sheet printed materials designed for wide distribution — events, promotions, announcements, and advertising.
Flyers come in several standard sizes, all based on common paper formats: full-page (8.5×11" / A4), half-page (5.5×8.5"), quarter-page (4.25×5.5"), and third-page (3.67×8.5"). The full-page format is most common for event posters and detailed promotional materials. Half-page is popular for handouts and door-to-door distribution.

Best practices
- •Design at 2550×3300px (300 DPI) for full-page flyers. Half-page is 1650×2550px.
- •The most important info should be readable from arm's length — use 24pt+ headlines.
- •Include 3mm bleed for professional printing. Use 100-170 GSM paper for a good weight-to-cost balance.
Bookmark750×2550px
The most common bookmark size is 2.5×8.5 inches (63.5×215.9mm). At 300 DPI, that's 750×2550 pixels. Other popular sizes include 2×8 inches and 2×6 inches. Bookmarks are a popular promotional print item for bookstores, libraries, events, and book launches.
Bookmarks don't have a single universal standard, but 2.5×8.5 inches is the most common size in the US — it's the same width as a third of a Letter sheet, making it efficient to print three bookmarks across one 8.5×11 sheet. Other common sizes are 2×8 inches (slimmer, fits paperbacks well) and 2×6 inches (more compact).

- •Include 3mm bleed and crop marks for accurate trimming.
Tri-Fold Brochure3300×2550px
A standard tri-fold brochure is 11×8.5 inches (279.4×215.9mm) unfolded, creating three panels of approximately 3.67×8.5 inches each. At 300 DPI, the full unfolded canvas is 3300×2550 pixels. Tri-folds are the most common brochure format for marketing materials, menus, and informational handouts.
A tri-fold brochure starts as a single Letter-size sheet (11×8.5") printed on both sides, then folded twice to create six panels (three front, three back). The standard fold is a "letter fold" or "C-fold" where the right panel folds inward first, then the left panel folds over it. The inner right panel is typically 1/16" narrower to nest cleanly inside.

Best practices
- •Design at 3300×2550px (300 DPI) for the full unfolded sheet. Each panel is ~1100px wide.
- •The inner fold panel should be ~1/16" narrower than the outer panels to nest cleanly.
- •Design both sides as separate pages in your PDF. Include fold marks and 3mm bleed.
Bi-Fold Brochure3300×2550px
A standard bi-fold brochure is 11×8.5 inches (279.4×215.9mm) unfolded, folding in half to create four panels of 5.5×8.5 inches each. At 300 DPI, the unfolded canvas is 3300×2550 pixels. Bi-folds are simpler than tri-folds and work well for menus, programs, and product showcases.
A bi-fold brochure is the simplest folded format: one fold down the center of a Letter-size sheet creates four panels (two front, two back), each 5.5×8.5 inches. The fold can be vertical (portrait booklet) or horizontal (landscape booklet). The portrait fold is most common for brochures.

Best practices
- •Design at 3300×2550px (300 DPI). Each panel is 1650×2550px (5.5×8.5").
- •The inside spread reads as a single wide canvas when open — use it for hero imagery or comparison layouts.
- •No bleed on the fold line. Include 3mm bleed on all outer edges only.
Rack Card1200×2550px
The standard rack card is 4×8.5 inches (101.6×215.9mm). At 300 DPI, that's 1200×2550 pixels. Rack cards are tall, narrow marketing materials designed to fit in brochure display racks found in hotels, tourist centers, restaurants, and retail stores.
Rack cards are specifically designed to fit in standard brochure display racks — the kind you see in hotel lobbies, tourist information centers, real estate offices, and restaurant vestibules. The 4×8.5" size is the industry standard that fits all standard display racks.

- •Print on 300-350 GSM cardstock with UV coating for durability in high-traffic display racks.
- •Include 3mm bleed. The 4" width is a tight canvas — keep layouts simple and text large.
#10 Envelope2850×1237px
The #10 envelope is 9.5×4.125 inches (241.3×104.8mm) — the standard business envelope in the United States. It fits a Letter-size sheet folded in thirds. At 300 DPI, the printable area is 2850×1237 pixels. It's used for business correspondence, invoices, checks, and direct mail.
The #10 envelope is the standard business envelope in the US, used for virtually all professional correspondence. It's designed to hold a standard Letter-size (8.5×11") sheet folded into thirds (each fold panel is ~3.67" tall). The envelope has a flap on the long edge.
Dimensions

Best practices
- •Fits a Letter-size sheet folded in thirds. The most common business envelope in the US.
- •Account for the address window position (if applicable) and USPS barcode area in your design.
- •No bleed — envelope printing is inset from the edges. Provide a flat template at exact dimensions.
Door Hanger1050×3300px
The standard door hanger is 3.5×11 inches (88.9×279.4mm). At 300 DPI, that's 1050×3300 pixels. Door hangers include a die-cut hole or hook slot near the top for hanging on door knobs. They're a popular format for local business marketing, real estate, and hospitality.
Door hangers are designed to be hung on door knobs or lever handles. The standard 3.5×11" size includes a die-cut hole (typically 1.5" diameter) positioned about 1" from the top. Some designs use a hook slot instead of a round hole. The area above the die-cut is essentially wasted on one side, so put your key message below it.

Best practices
- •Design at 1050×3300px (300 DPI). Account for the die-cut hole ~1" from the top.

Frequently asked questions
What are the standard print sizes?
Business card: 3.5×2". Postcard: 6×4". Poster: 24×36". Flyer: 8.5×11". Bookmark: 2.5×8.5". All at 300 DPI for high-quality printing.
What DPI should I use for printing?
300 DPI for high-quality prints (photos, marketing materials). 150 DPI is acceptable for large posters viewed from a distance.
What is bleed in printing?
Bleed is the area beyond the trim edge (typically 3mm / 0.125") where your design extends. It prevents white edges if the cut is slightly off. Always include bleed for professional printing.
What is the safe zone in print design?
The safe zone is 0.25 inches (6mm) inside the trim line. Keep important text and logos within this area to prevent accidental cropping from cutting variations. The trim line is where the blade cuts; bleed extends 0.125" beyond it.
What color mode should I use for printing?
CMYK for professional offset and digital printing. RGB colors are converted to CMYK during production and may shift noticeably — especially bright blues and greens. Set your document to CMYK from the start and use 300 DPI resolution.
