Why AI-Generated Business Cards Get the Layout Backwards

Ask a model for a business card design for a Tokyo office and you reliably get a Western card with Japanese text in it: name largest and at the top, company small underneath, everything on one side, at 3.5 by 2 inches. Every one of those four decisions is wrong for the context.

What a generated template produces

The generated layout is not random; it is a specific, consistent Western convention. Name in the largest type at the top or centre, job title beneath it, company name and logo smaller, contact details in a block at the bottom, a single printed side, and a landscape rectangle sized to the North American standard. That is a good card in New York and a card that reads as an outsider’s in Tokyo, Seoul or Osaka.

It matters more than layout usually does because a 名刺 (meishi) is exchanged in a formal ritual at the start of a meeting and read immediately, in front of you. It is not filed for later; it is used in the next thirty seconds to work out how to address you.

The card is not the size you assumed

Three regional standards are in common use and they are all different:

Japan (meishi, "4-gou")   91 x 55 mm     (3.58 x 2.17 in)
Europe / much of Asia     85 x 55 mm     (3.35 x 2.17 in)
United States / Canada    3.5 x 2 in     (88.9 x 50.8 mm)
ISO 7810 ID-1 (bank card) 85.60 x 53.98 mm

The Japanese card is both wider and taller than the US one. That is not a design preference — Japanese card cases, card holders and the trays used to receive cards during a meeting are built for 91 by 55 mm, and a US-sized card sits loose in them. Sending artwork at the wrong dimensions to a Japanese printer produces either a rejected file or a card trimmed to the wrong aspect ratio.

The European 85 by 55 mm size is close to but not the same as the ISO 7810 ID-1 credit-card size of 85.60 by 53.98 mm, which is the one people reach for when they want “the standard”. A card at ID-1 dimensions is 1 mm short, which is invisible on screen and visible in a stack.

Organisation first, person last

The Japanese vertical order runs from the largest entity to the smallest, and the person is the smallest:

株式会社ムルチグリッド        company (kabushiki-gaisha ... )
営業本部 第一営業部          division, then department
部長                        title / rank
山田 太郎                    name  <- largest type on the card
やまだ たろう                furigana reading, small, above or beside the name

Note two things. The name is still set in the largest type — it is last in reading order but first in visual weight — and the department hierarchy is spelled out to a level of detail a Western card omits entirely. The rank (部長 buchou, 課長 kachou, 係長 kakarichou) is a specific position in a well-understood ladder, not a marketing title, and translating it as “Head of Sales” loses the information the recipient is actually looking for.

The name itself is family name first — 山田 太郎 is Mr Yamada — and the furigana line exists because a Japanese surname written in kanji often has several possible readings, so the card tells you how to say it. Generated cards omit the furigana line almost without exception. The same family-name-first ordering applies on Korean cards, where the person’s name is sometimes additionally given in hanja alongside hangul for the same disambiguating reason, and the name-order question is worth settling for your whole system, not just the card.

Bilingual means two sides

The single most common structural error is putting Japanese and English side by side on one face. The convention is one language per side: Japanese on the front, English on the reverse, each laid out to its own conventions rather than as a translation of the other’s layout.

That means the reverse is a proper Western card — name prominent at the top, given name first, romanised — and not a mirrored copy of the Japanese face. It also means the two sides can legitimately carry different things: the Japanese side may use the vertical writing direction 縦書き, read top to bottom and right to left, which the English side obviously cannot.

Vertical setting has one consequence a template has to handle: numerals in vertical Japanese text are conventionally written in kanji (二〇二六) or set with the 縦中横 technique that rotates a short run of Latin digits to read horizontally within the vertical line. Dropping a horizontal phone number into a vertical column without either treatment gives you digits stacked one above the other, which is the giveaway of an automated layout.

The address and phone blocks

The address on the Japanese side is ordered largest to smallest, the reverse of the Western order, and prefixed with the postal mark:

〒100-0005
東京都千代田区丸の内1-2-3  丸の内ビル 8F
TEL 03-1234-5678
FAX 03-1234-5679

The 〒 character is U+3012 POSTAL MARK and it precedes the postcode; the postcode itself is three digits, a hyphen and four. Then prefecture, ward, district, block and building — each one narrowing. The English side reverses the whole sequence: building, street, ward, city, prefecture, postcode, Japan. Getting the address order right per side is not optional; a Japanese address written smallest-first is unusable for domestic post.

Phone numbers on the Japanese side use the domestic form with the trunk zero, 03-1234-5678, and on the English side the international form, +81 3 1234 5678, with the zero dropped. Printing the same string on both sides is wrong on one of them, for the reasons set out in phone number formatting by country.

Why the order follows from the exchange

The layout is not arbitrary, and knowing why makes it easy to remember. Cards are presented with both hands, held so that the text faces the recipient, with a slight bow, and the more junior person presents first. The recipient reads the card immediately and then places it on the table in front of them for the duration of the meeting, often arranged to match the seating so they can keep track of who is who.

So the card is read once, quickly, by someone deciding how to address you and where you sit in the other organisation. Company, then division, then rank, then name is exactly the order in which those questions are asked. The Western order — who are you, what do you do, who for — is the order a card gets read in when it is pulled out of a wallet three weeks later.
