class=\"wp-block-heading\">QR Code Size on a Business Card by Card Format<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>US standard card (3.5 x 2 inches): a 0.8 inch code takes 40% of the card height. Place it on the back so the front stays clean.<\/li>\n<li>European standard card (85 x 55 mm): use 20 to 25 mm. The same 2 cm rule applies.<\/li>\n<li>Folded or square cards: you have more room, so use 1 inch (2.5 cm) or larger and keep the code away from the fold.<\/li>\n<li>Back of the card only: if the front is full, put a 1 inch code on the back with a short line such as &#8220;Scan to save my contact&#8221;.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Data Density Dictates Code Size<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The size of your QR code depends on how much data it holds. A QR code is a grid of small squares called modules. Version 1 has 21 x 21 modules and Version 40 has 177 x 177 modules. More data means more modules, and each module gets smaller when the code size stays the same. If the modules print smaller than a camera can resolve, the scan fails.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the math for a 2 cm (0.8 inch) code. A short link usually fits in a Version 2 code (25 modules), so each module is about 0.8 mm. A full contact record can need Version 10 or higher (57 modules or more), and each module drops to about 0.35 mm. The second code is much harder to print and scan at the same size.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A direct vCard with your name, phone numbers, email addresses and office address creates a dense grid. Using a <a href=\"https:\/\/pageloot.com\/ja\/vcard-qr-code-generator\/\">vCard QR\u30b3\u30fc\u30c9\u30b8\u30a7\u30cd\u30ec\u30fc\u30bf\u30fc<\/a> to create a direct static file often needs a code of 1 inch (2.5 cm) or more to stay readable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To keep your code compact and easy to scan on a small card:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Encode a short link to your contact page instead of long raw contact text.<\/li>\n<li>Keep only the essential contact channels.<\/li>\n<li>Keep the module count low so each square stays large and sharp.<\/li>\n<li>Follow the principles for how to <a href=\"https:\/\/pageloot.com\/ja\/how-to\/business-card-design-qr-code\/\">design a business card with a QR code<\/a> to balance layout and function.<\/li>\n<\/ul>\n\n\n\n<p
