Business Card Size, Bleed, and Safe Zone Guide

The phrase “standard business card” is regional. North American cards are 3.5 by 2 inches. Most of Europe and the UK use 85 by 55 millimeters. Japanese meishi cards run a little wider at 91 by 55 millimeters. Square and mini formats are common at MOO and a handful of boutique printers but are not what most production printers reach for as a default.

Pick the regional format before judging layout. A name set in 11-point type can feel right on a US card and feel cramped on an EU card with the same composition, because the EU card is narrower and shorter at the same time. Designing at the wrong size and rescaling later compounds rounding errors and pushes type and rules off their intended grid. For the conceptual primer on what print-ready actually means before any of these numbers, see what makes a business card print-ready.

Three rectangles describe a printable card: the trim line where the blade cuts, the bleed line that extends past the trim, and the safe zone that sits inside the trim. Every printer worth using publishes the same three rectangles, sometimes under slightly different names.

• Trim — the final cut dimension, what the customer holds in their hand.
• Bleed — extra background extending past the trim, typically 3 mm or 0.125 in on every side, so background art still reaches the edge after slight blade drift.
• Safe zone — an inset margin inside the trim, also 3 mm or 0.125 in by convention, where critical content like names, emails, and QR codes belongs.

VistaPrint and MOO both publish a 3 mm / 0.125 in bleed and a 3 mm safe inset as their defaults. A small number of printers ask for 5 mm or 1/4 in, especially on thicker or letterpressed stock. Read the printer’s template once before exporting; do not assume.

The safe-zone rectangle is a hard floor, not a target. Real layouts breathe better when text holds an extra millimeter or two off that line, especially on cards with full-bleed photography or strong color blocks.

• Names and headlines: at least 4 mm from trim, 9–12 pt minimum so the name reads at arm’s length under office light.
• Body text (job title, company, secondary details): at least 4 mm from trim, 8–9 pt minimum, never below 6 pt on coated stock.
• Email and phone: at least 4 mm from trim; consider tabular figures so digits align in vertical lists.
• QR codes: at least 5 mm from trim and a 4-module quiet zone on every side. The quiet zone is part of the QR specification, not a stylistic suggestion.
• Hairlines and rules: at least 0.25 pt at 300 DPI; thinner strokes can disappear after press dot gain on uncoated stock.

Designing the front and back to the same safe-zone discipline keeps both sides feeling like one card. Asymmetric insets are usually a sign that one side was finished and the other side was rushed.

A QR code’s printed size is set by its module size — the dimension of one black square — multiplied by the number of modules on a side, plus the 4-module quiet zone the spec requires. DENSO WAVE, the company that invented QR Code, publishes a printer-aware guide: at 300 DPI thermal printing, the safe minimum module is around 0.33 mm in a 4-dot rendering. At 600 DPI laser, modules can drop to 0.17 mm and still scan.

Translated into business card practice: a 33-module Version 4 code (a typical short URL at medium error correction) at a comfortable 0.55 mm per module needs about 18 mm of width for the modules themselves, plus a 4-module quiet zone (≈2 mm) on each side. The full footprint lands near 22 mm on a side. A simpler 25-module Version 2 code can come in closer to 17 mm including quiet zone. Going meaningfully below either threshold risks unreliable scans on textured or matte stock.

• Aim for at least 18 mm / 0.7 in per side of the rendered module area, before adding the quiet zone.
• Reserve 4 modules of quiet zone on every side. Do not decorate it with frames, gradients, or rounded corners.
• Use medium (M) or quartile (Q) error correction for printed cards. Higher error correction is slightly larger on the page but survives fingerprints, ink absorption, and uncoated bleed.
• Test scans from arm’s length on the proof, not from the design file on a screen.

The design-side decisions — placement, contrast, and integration with the rest of the layout — are covered in QR code business card layout tips. The size math above is the floor; the layout post is how to spend it well.

A correct file passes a printer’s preflight quietly. A wrong file gets bounced, sometimes silently re-rasterized in ways that make Monday’s delivery look nothing like Friday’s proof. Before clicking upload, walk this checklist.

• Color mode: CMYK, not RGB. RGB blues and oranges that look correct on screen shift visibly under press inks.
• Resolution: 300 DPI minimum for raster art and photography; 600 DPI for fine line work or rasterized type.
• Bleed: 3 mm or 0.125 in extending past every trim edge, even where the design appears blank. White can be a deliberate background.
• Crop marks: required by some printers, forbidden by others. Read the upload page; do not export blind.
• Fonts: outlined or fully embedded. Subset embedding is safe; reference-only embedding is not.
• Pages: one page per side, not a single spread, and not a multi-card imposition.
• Color profiles: GRACoL, FOGRA, or whatever the printer specifies. If unspecified, US printers usually expect GRACoL 2013 or SWOP coated.
• Transparency: flatten before export to avoid soft-light or screen blends rendering unpredictably on press.

Before paying for a print run, run the file through a five-minute desktop proof. It catches more bugs than another design pass.

1. Print at 100% scale on letter or A4 paper. Disable auto-fit and verify the printer driver is not silently scaling.
2. Cut along the trim line with a metal ruler and a sharp knife.
3. Place a real existing business card next to the cutout. The size should match within a millimeter; if it does not, the file is wrong, not the printer.
4. Hold the proof at arm’s length and read the smallest text. If it requires effort under office light, increase the size before ordering.
5. Scan the QR with a phone from 30–40 cm away. If the first scan is slow, the printed run will be slower.
6. Hold the proof against a window to check front-to-back alignment. Backs that drift more than 1–2 mm look cheap on real stock.

Kleido designs every card at the selected trim size with safe interior margins and vector QR codes, then prepares the production file behind the scenes when you order prints.
