How to use
- Choose the "Envelope type" and "Writing direction". For vertical text you can also choose how numbers look under "Numbers in vertical text".
- Fill in "Recipient postal code", "Recipient address", "Recipient name" and "Honorific", then the sender fields. The life-size preview shows the layout.
- Press "Print", set the paper size to the envelope and the scale to 100% in the print dialog. Do a test print on plain paper first.
Notes
- In the print dialog pick the envelope size as the paper size and set the scale to 100% (actual size). How envelopes are fed, and in which orientation, differs by printer, so print a test on plain paper before using a real envelope.
- Positions are a close approximation of a typical envelope layout and can be a few millimetres off the official boxes. If your envelope already has postal code boxes printed, turn off "Print postal code boxes" so only the digits are printed.
- Long address columns run off toward the left. Add line breaks or reduce "Address font size (mm)" if that happens.
- In tate-chu-yoko, up to two digits are set sideways in one cell and longer numbers are stacked vertically. A hyphen between digits becomes a long-vowel dash (ー).
- Names and addresses you type are processed only in your browser. Nothing is saved or sent, and it disappears when you close the page.
Glossary
Nagagata 3 / Western style 4
Standard Japanese envelope sizes. Nagagata 3 is 120 × 235 mm and fits A4 folded in three; Western style 4 is 105 × 235 mm, a wide Western-style envelope. Both are printed as landscape sheets.
Tate-chu-yoko
A typesetting style where a short run of digits, usually two, is laid out horizontally inside vertical text, which keeps house numbers like 23 readable. In CSS it is text-combine-upright.
FAQ
The print position is off when I use a real envelope.
Check that the print scale is 100% (actual size) and the paper size matches the envelope. How envelopes are fed, and in which orientation, depends on the printer. Print a test on plain paper, lay it over the envelope and hold both up to the light to see how they line up.
My envelope already has postal code boxes. What should I do?
Turn off "Print postal code boxes" to print only the digits. The box positions here can be a few millimetres off the official ones, so do a plain-paper test and compare it with your envelope.
Should I use Arabic digits or kanji numerals in vertical text?
Both are used in practice. "Arabic digits (tate-chu-yoko)" sets up to two digits sideways, which keeps street numbers easy to read. "Kanji numerals" writes positional kanji such as 一丁目二番三号 (10 becomes 一〇). Pick whichever matches your convention.
My address runs off the envelope. How do I fix it?
In vertical writing, long columns overflow toward the name. Break the address at natural points so it splits into more columns, or reduce "Address font size (mm)". The life-size preview shows the result.
