The Five Core Personal Organizer Sizes

The Five Core Personal Organizer Sizes


ASHFORD personal organizers are available in five different sizes. Larger sizes provide more writing space, while smaller sizes offer greater portability and lighter weight.

[A5]
The Largest Size for Generous Writing Space

[Recommended for users who…]

○ Want plenty of space for writing and organizing information

○ Mainly use their personal organizer at a desk

○ Want to store and carry folded A4 documents and related materials

※Refill size = 210 × 148mm

A5 is the largest size in the personal organizer lineup. The refill size is approximately equivalent to the Half Letter size. Shown in the photo is the “Deep A5 19mm belt,” placed on blue Letter-size paper for scale. The wide page area provides ample space for writing, making it ideal for users who primarily use their personal organizer at a desk or for business professionals who travel mainly by car. Folded Letter-size documents can also be stored directly inside the interior pockets.

[HB×WA5]
A Unique Square-Like Format Combining A5 and BIBLE Size

[Recommended for users who…]

○ Want a practical size positioned between A5 and BIBLE

○ Prefer a wider square-style layout based on BIBLE proportions

○ Enjoy writing not only text, but also sketches, diagrams, and illustrations

※Refill size = 170 × 148mm

HB×WA5 is an innovative format originally developed by ASHFORD in 2010. The name comes from its dimensions: Height equals BIBLE size, while Width equals A5. Shown in the photo is the “Deep HB×WA5 25mm belt,” placed on blue Letter-size paper. By extending the width of the BIBLE format, the page becomes closer to a square proportion. It combines the strengths of both A5 and BIBLE sizes, making it ideal for users who want generous writing space while maintaining portability.

The refill page area is approximately 1.5 times larger than BIBLE size, allowing plenty of room for diary entries. It is also ideal for those who enjoy Lifelog, as stickers and paper cuttings can be attached easily. Because the ring mechanism is the same as BIBLE size, BIBLE-size refills and accessories such as page finders and clear holders can also be used interchangeably.

[BIBLE]

The Standard and Most Versatile Classic Size

[Recommended for users who…]


○ Are new to personal organizers or experienced heavy users alike

○ Want to choose from the widest variety of jackets and refills

○ Prefer carrying cards and small essentials together with their personal organizer

※Refill size = 170 × 95mm


BIBLE size is the most standard and widely used personal organizer format. Both jackets and refills are available in an extensive variety, making it popular among everyone from beginners to experienced enthusiasts. Shown in the photo is the “Vitalita BIBLE 19mm note,” opened flat on blue Letter-size paper. Its balanced vertical shape makes it easy to carry while still opening comfortably on a desk. The refill area is approximately half the size of A5, providing more than enough space for typical everyday writing.

BIBLE size adapts naturally to both business and personal use. Because the width is close to that of a standard business card, storage refills such as “Business Card Holders” and “Card Holders” make it easy to organize and carry cards efficiently.

[MINI6]

A Compact Size That Balances Portability and Writing Comfort

[Recommended for users who…]

○ Want a compact personal organizer that is easy to carry

○ Need portability while still maintaining comfortable writing space

○ Feel MICRO5 is slightly too small for everyday writing

※Refill size = 126 × 80mm


MINI6 offers an excellent balance between compact portability and practical writing space. Shown in the photo is the “Deep MINI6 13mm belt,” placed on blue Letter-size paper.
Its moderate size allows it to open comfortably even on small meeting tables or café counters. It also fits naturally in the palm of the hand, making it convenient for writing while standing.
ASHFORD has been producing MINI6 personal organizers since 1991. A wide variety of refills are available, along with many fashionable and playful designs. It is also an ideal size for carrying together with standard pens around 15cm in length.

[MICRO5]

The Smallest Size for Maximum Portability

[Recommended for users who…]

○ Want to carry a personal organizer everywhere

○ Prefer quickly capturing notes and ideas anytime

○ Want to minimize overall luggage and weight


MICRO5 is the smallest size in the ASHFORD personal organizer lineup. ASHFORD has been producing MICRO5 models since 1994. It is an ideal format for quick notes and personal reminders. Shown in the photo is the “Deep MICRO5 11mm meishi phone,” placed on blue Letter-size paper. Compact enough to fit comfortably into a pocket or the corner of a bag, MICRO5 allows users to carry a personal organizer effortlessly wherever they go. Because MICRO5 refills are close in size to business cards and standard cards, the format is also highly practical for organizing cards and contact information.
Using storage refills such as “File Cases” and “Double Card Holders” make it possible to securely and efficiently carry credit cards and other essentials. MICRO5 is also attracting attention as a new generation wallet-style personal organizer.
