## What is One Line a Day?

**One Line a Day: A Five-Year Memory Book is a small hardcover diary from Chronicle Books with one page per calendar date and room on each page for five short entries, one per year.** You write a line today, then return to the same page a year later and see what you wrote.

Chronicle published the original on September 2, 2009, and the format became a series: Chronicle's product page says One Line a Day books have sold over 3 million copies. It pitches the book at people who find a full diary page daunting.

Chronicle's trim is the page size; the Hardie Grant and Amazon figures include the hardcover boards, so we draw the 102 × 165 mm figure. Chronicle doesn't give a paper weight. Amazon's From the Publisher panel lists a ribbon marker and metallic foil or page edges across the series.

![To-scale drawing of One Line a Day, 102 × 165 mm, against an A6 outline of 105 × 148 mm and an A5 outline of 148 × 210 mm](https://stationerytimes.com/images/chronicle-one-line-a-day-size.svg)

*One Line a Day is about as wide as A6 but 17 mm taller, and far smaller than A5.*

## How does a One Line a Day page work?

**Each page is one date, divided into five stacked sections; each year you write in the next section down.** From the second year on, the entries from past years on that date sit right above today's.

Amazon reviewers describe five or six thin lines per section, an If found page at the front and three Dates to Remember pages at the back. The pages carry no year, so you can start on any date.


## How big is One Line a Day?

**At about 102 × 165 mm (4 × 6.5 in) and 340 g, it is close to a 4 × 6 photo and fits a nightstand drawer or a handbag.** It is narrower than an A5 book but thick, at 34 mm, because 372 pages are bound into a small trim.

That compact size is the trade-off: a few words per year rather than a paragraph.

## How does One Line a Day compare to other five-year journals?

**One Line a Day is the simplest and cheapest of the popular five-year books; others add prompts, bigger pages or fountain-pen paper.**

| | One Line a Day | Q&A a Day | Some Lines a Day | Midori 5-Year Diary |
|---|---|---|---|---|
| Prompt | None | A question a day | None | None |
| Size | 102 × 165 mm | 110 × 161 mm | 145 × 210 mm (A5) | 117 × 185 mm |
| Pages | 372 | 368 | 365 | 366 + 3 |
| Paper | Not stated | Not stated | 80 g/m² | MD Paper |
| Price band | $$ | $$ | $$$ | $$$ |

If you want a prompt, [Q&A a Day](https://stationerytimes.com/guides/qa-a-day-5-year-journal/) asks one question per date. For more room, the A5 [Leuchtturm1917 Some Lines a Day](https://stationerytimes.com/guides/leuchtturm1917-some-lines-a-day/) gives each year about 4 cm of page. For fountain pens, the [Midori 5-Year Diary](https://stationerytimes.com/guides/midori-5-year-diary/) uses MD Paper.

Our [best 5-year journals](https://stationerytimes.com/guides/best-5-year-journals/) roundup compares all of them.

## Which One Line a Day edition should you choose?

## Frequently asked questions

### How does the One Line a Day journal work?

Turn to today's date and write a line or two in the first empty section. Next year you write in the section below, so after five years each page holds five entries for the same date.

### How many pages are in One Line a Day?

Chronicle Books lists 372 pages; Amazon gives a print length of 370. That covers 365 date pages plus a few extra pages, which reviewers describe as an If found page and three Dates to Remember pages.

### What size is One Line a Day?

Chronicle gives a 3.75 × 6.125 in trim. Hardie Grant lists the finished hardcover at 102 × 165 × 34 mm and Amazon at 4 × 6.4 × 1.33 in, so it is about the size of a 4 × 6 photo.

### Can you start One Line a Day in the middle of the year?

Yes. The pages carry the day and month, not the year, and Amazon reviewers describe starting on the day the book arrived. Your five years then end on the day before your start date.

### How much can you write in One Line a Day?

A sentence or two per year. Amazon reviewers count five or six thin lines per section, so people with large handwriting say they have to write smaller.

### Is One Line a Day good for fountain pens?

Chronicle doesn't publish a paper weight, and we haven't tested it yet. If you use a fountain pen, try a fine nib on the last page first.

### How much does One Line a Day cost?

Chronicle Books sells the original in our $$ band ($5–20 per notebook). Hardie Grant lists it at A$28.99 (about US$20) in Australia.

### Where is One Line a Day printed?

The listings we read don't say. Chronicle Books is a US publisher; check the copyright page of your copy for the printer.
