What is The Size of A5 Paper - In Inches, CM And Millimeters?

When you shop for notebooks, flyers, or planners, you will often see the term “A5.” Many people wonder what size A5 really is. In this guide, we explain the A5 paper size in simple terms, why it is popular, and how it compares to other sizes you may already know.

A5 is part of the ISO 216 international paper size system. This system is used in most countries around the world. It keeps paper measurements consistent, which makes printing and office work much easier.

A5 may seem small, but it offers a perfect middle ground between compact size and usable writing space. It is popular for personal projects and professional tasks.

A5 Paper Size in Millimeters, Centimeters, and Inches

When asking “What size is A5?”, the answer depends on the unit you prefer to use. The A-series paper sizes are based on metric measurements.

Below are the exact and commonly used A5 dimensions.

Measurement Type	A5 Paper Size
Millimeters (mm)	148 × 210 mm
Centimeters (cm)	14.8 × 21 cm
Inches (exact)	5.82 × 8.26 in
Inches (rounded)	5.8 × 8.3 in
Print Area	48.43 sq in

These sizes make A5 a great choice when you want something smaller than A4 but still large enough to write clearly on.

How A5 Compares to A4 Paper

You may already know A4 because it is the most common office paper size. A5 is exactly half the size of an A4 sheet. If you take a standard A4 sheet and fold it in half across the width, you get A5.

This simple scaling is one of the key benefits of the A-series system. Designs can be resized up or down without losing shape or layout. That makes A5 printing simple, affordable, and fast.

Only two quick bullet points to support understanding:

• A5 is half of A4 and double the size of A6

• The sides always scale in the same ratio, keeping everything neat

Why Is A5 Paper So Popular?

A5 paper is widely used because it strikes a balance between portability and writing room. It fits well in bags, clipboards, and even some pockets. At the same time, the space is enough for notes, sketches, planning, or printing.

People like that A5 looks professional while still being easy to carry around. It feels more personal than larger sheets and less cramped than smaller ones.

Common Uses for A5 Paper

The size of A5 paper makes it perfect for many everyday tasks. It is used in homes, schools, and offices. You will often see A5 in printed handouts and small documents.

Typical uses include:

• Notebooks and journals

• Flyers, handouts, and menu inserts

• Personal planners and diaries

• Greeting cards and invitations

• Product manuals and booklets

Businesses also use A5 for marketing because it is cheaper to print and easy for customers to hold on to. A5 flyers are a popular choice for events or store promotions.

Why Designers and Printers Love A5

A5 works well because it saves space and materials without sacrificing clarity. Designers know that A5 layouts feel cleaner, especially when centered with wide margins.

Some benefits include:

• Easy to scale from A4 or A3

• Cost-effective for bulk printing

• Portable and lightweight

• Better ergonomics for handheld reading

Anyone designing for A5 can maintain readability with slightly larger fonts and tighter spacing. It allows striking visuals while keeping documents budget-friendly.

A5 Paper in Printing and Design

Graphic designers enjoy working with A5 because of its flexibility. When a layout is designed for A4, it can be scaled down to A5 with great results. There is no need to reshape or crop parts of the design. This helps keep printing costs lower and saves time.

A5 also supports both portrait and landscape designs well. Portrait is great for notebooks or booklets. Landscape works nicely for display cards, short presentations, and small calendars.

A5 vs. Other Common Paper Sizes

Here is a quick table to help you see where A5 fits among other familiar sizes:

Paper Size	Dimensions (mm)	Comparison to A5
A4	210 × 297	A4 is twice the size of A5
A5	148 × 210	Standard medium-small size
A6	105 × 148	A6 is half the size of A5

This sizing system helps you choose the best format based on what you want to print.

Should You Choose A5 Paper?

The answer depends on your project. A5 is a smart option when you need a balance of size, cost, and usability. It offers roomy writing space without taking up too much room in your bag or on your desk.

People who take notes often or love planning tools usually find A5 comfortable and efficient. For businesses, it is budget-friendly and still looks professional.
