US Standard Business Card Size
The most common business card size in the United States is 3.5″ × 2″ (88.9 × 50.8 mm).
This rectangular shape is designed to fit wallets, card holders, and pockets with ease. Almost all US-based businesses default to this format because it’s familiar, functional, and highly versatile.
Why choose the US standard size?
Universal Fit
This size aligns with wallets, envelopes, sleeves, and standard card cases — meaning your card fits seamlessly wherever people store important contacts.
Recognizable + Professional
Clients expect this size, which means it fits their mental model of what a business card “should” look like.
Works with any industry
From attorneys and real estate agents to coaches, restaurants, and freelancers, the US standard size suits most branding styles and professions.
Plenty of design opportunities
Vertical or horizontal layouts both work beautifully, and you have enough room for key details without clutter.
If you’re sticking with the classic look but want something elevated, consider premium, fat, thick, or ultra-thick stock to create a stronger impact.

European Business Card Size
European business cards are slightly larger than the US standard, measuring 3.35″ × 2.17″ (85 × 55 mm). This size is common across the UK, EU countries, and many international corporate environments.

A More Refined, Modern Look

Clean Layouts
With extra horizontal space, Euro cards are ideal for minimalist designs, larger logos, or professionals with longer titles.
International Impression
If your business works with global clients, this size immediately signals international standards.
Great for luxury branding
The larger size pairs beautifully with premium stocks, elegant typography, and spacious layouts.

Square Business Cards
Square cards (typically 2″ × 2″ or 2.5″ × 2.5″) break away from traditional proportions to create something unique, playful, and highly memorable.
Why choose square business cards?
Instantly Noticeable
Because they don’t resemble a standard card, they grab attention the moment they’re handed out.
Perfect for modern brands
Creative professionals, boutiques, cafés, wellness brands, and designers often prefer squares for their trendy, social-media-ready look.
Compact and versatile
Square cards can double as mini thank-you notes, packaging inserts, product tags, or branding pieces inside shipments.
Great for bold logos
If your logo is symmetrical or geometric, square cards showcase it beautifully.
Square cards aren’t just business cards, they’re branding tools.
