Answer in brief
Start from your printer's template, because business card sizes differ by country: 3.5 x 2 inches in the United States and Canada, 85 x 55 mm in much of Europe. Extend the background into the bleed, keep text inside the safe zone, set raster images to 300 DPI and work in CMYK. Put on the card only what a person needs to contact you.
Business card sizes by region and why you start from a template
Before you open any editor, decide where the card will be printed, because that sets its size. Wikipedia notes that there is no standard for business card dimensions, and its table shows how far practice differs: 88.9 x 50.8 mm (3.5 x 2 inches) in the United States and Canada, 85 x 55 mm in the United Kingdom, France, Germany, Italy and Spain, 90 x 55 mm in Australia, India and Sweden, and 90 x 50 mm in Russia, Brazil, Mexico and Ukraine. If you are working out how to design a business card for more than one country, choose the size of the market where most cards will be handed out.
The same article points out that a payment card, defined in ISO/IEC 7810 as 85.60 x 53.98 mm, is almost the size of a Western European business card, which makes cards easy to store in a wallet. Do not stretch a design from one size to another. A card that is two millimetres taller will have its margins cut differently, so open the template your printer gives you and draw inside it.
Bleed, trim and safe zone: three lines around every card
A card is printed on a larger sheet and cut. The cut line is the trim. Wikipedia explains bleed as printed content that extends past the trim line, and gives the reason: paper can shift during cutting, so the extra area makes sure no white edge appears. Any background colour or photo that touches the edge of the card must continue into the bleed.
The size of the bleed depends on the printer. Wikipedia's article on business cards quotes 3.175 mm (one eighth of an inch) up to 6.35 mm on each side, its article on bleed quotes 2 to 5 mm in metric work, and the Vistaprint size guide shows a US artwork file of 3.61 x 2.11 inches for a 3.5 x 2 inch card. Those numbers disagree, which is the whole point: use the figure from your own printer's template.
Inside the trim sits the safe zone, the area where text and logos are safe from the knife. Vistaprint gives 3.36 x 1.86 inches for the safe printing area of a standard US card. Keep names, numbers and the logo inside it, and let only background and decoration run to the edge.
Resolution and colour mode: 300 DPI, CMYK and what changes in print
Vistaprint says raster artwork should be set to 300 DPI and recommends working in CMYK. At that resolution a standard US card trim is 1050 x 600 pixels, and the file with bleed is slightly larger. A photo that looks sharp on a phone may have too few pixels for print, so check its real dimensions before you place it on the card.
CMYK stands for cyan, magenta, yellow and black, the inks of colour printing. Wikipedia describes it as a subtractive model, where ink absorbs light reflected from the paper, while a screen is additive and makes colour from light. Each model covers a different range of colours, so some colours you see on a monitor cannot be printed, and there is no universal formula to convert between them. That is why a bright screen blue can come back from the printer duller than expected.
What belongs on a card, and what to leave out
Wikipedia lists what a card has traditionally carried: the giver's name, the company with a logo, a street address, a telephone number, an email and a website. Modern cards may add social media addresses. For a small business, that list can be shortened: name, role, company, one phone number, one email and the website are enough for someone to reach you after a meeting.
Leave out what the person does not need in order to contact you. A fax number, a list of every service, three phone numbers and a block of slogans compete with the one thing a card must do, which is to be found in a pocket a month later and answered.
A QR code that opens a page you control
A QR code lets a person with a phone jump from paper to a page. The Denso Wave site, which presents QR Code as its own standardized code, lists its qualities: it holds a lot of data in a small printout, can be read from any direction, and can correct itself when partly smeared or damaged. These are good reasons to print one on a card, but it is optional. Wikipedia mentions a 2007 survey in which fewer than 3% of Japanese people owned a card with a QR code.
If you add one, point it to a page that you control, such as your contact page, rather than to a social profile or a temporary link. A card cannot be edited after printing, and a page can. The code needs room: Denso Wave says a margin is required around a QR Code, and that decorated or distorted codes may not be readable. Print it large enough for the printer's module size and test it with two or three different phones before you approve the file.
Paper, coatings and finishes in plain words
Paper changes what a card feels like in the hand. Wikipedia gives the usual stock as 350 g/m², also given as 12 pt in thickness, and says digital presses can print on stock up to 407 g/m². A heavier card feels more solid, but it must still fit your holder or cardholder.
Coatings and finishes are decisions about touch and wear. According to the same article, aqueous coatings are less noticeable and make a card more durable, while a glossy UV coating is more prone to fingerprints. Thermography applies plastic powder to wet ink and heats it to simulate engraving. Spot UV varnish on matte lamination can give a similar raised effect. Lamination makes thin cards thicker.
Unusual materials such as plastic, metal or wood exist and often keep the standard format, sometimes with rounded corners. A simple matte or lightly coated card is usually enough; spend the effort on layout and legibility first.
Proofing before the print run and the card as part of an identity
Before you order the full run, ask for a proof or print one copy. Look at the edges, where an uneven cut would show; at the smallest text, to see whether it reads at arm's length; and at the colours, which may differ from the screen. Scan the QR code from the paper. Then check spelling, numbers and the website address aloud, one by one, because an error in a contact detail is costly once the whole run has been cut.
A card is also one piece of a larger set. It should share colours, typefaces and the logo with the website, the invoice, the email signature and the packaging, so that a person who meets the card and then visits the site sees one company. That consistency is a matter of rules written once: a palette, a type choice and templates, rather than a fresh design for each item.
What to prepare before you order a brand identity
You can design a plain card yourself in a template if you have a logo, two or three colours and clear contact details. Ordering makes sense when those basics do not yet exist, or when the card has to match a website, packaging and documents made by different people. Prepare your company name, the contact details to show, any existing logo files, examples of styles you like and the list of places the identity will appear.
Brand identity at VITON13 Studio, on its service page, delivers a logo system, a palette, type and templates with a guide, and rules for 5 carriers of the identity. The price is from $93 AI-assisted or from $113 human-led, with 6–10 working days. Send the brief and the list of materials, and the scope and the price are confirmed in writing before the work starts.
Practical checklist
- Choose the print country first and open your printer's template for the card size.
- Extend backgrounds and photos into the bleed, and keep text inside the safe zone.
- Set raster images to 300 DPI and work in CMYK, then check every photo's real pixel size.
- Keep name, role, company, one phone, one email and the website; drop the rest.
- Order one printed proof and test the QR code on three phones before the full run.
Questions and answers
Can I design my own business cards without a designer?
Yes, if you have a logo, a few colours and clear contact details. Work inside your printer's template, keep text inside the safe zone and order a proof before the full run. A designer helps when the card must match a wider brand.
What is the standard business card size?
There is none. Wikipedia lists 3.5 x 2 inches in the United States and Canada, 85 x 55 mm across much of Europe and 90 x 50 mm in Russia and several other countries, so follow your printer's template.
What should I not put on a business card?
Skip anything a person does not need to contact you: a fax number, a long list of services, several phone numbers and crowded slogans. Keep type inside the safe zone so that the cut does not clip it.
Should I use CMYK or RGB for a card?
Vistaprint recommends CMYK for print files. Screens mix colour from light and print mixes it from ink, and some screen colours cannot be printed, so expect a printed colour to differ from the monitor.
Is a QR code on a business card worth adding?
It is optional. If you add one, link it to a page you control, leave a margin around it and test it on several phones. Denso Wave warns that decorated or distorted codes may not be readable.
