A5 Paper Size Guide

A5 is a popular paper size used for leaflets, booklets, invitations and small marketing materials. It is part of the international ISO A-series paper system and offers a compact format that is easy to distribute and handle.

In this guide we explain the A5 paper dimensions, how it compares to other A-series sizes, and the most common uses for A5 in printing.

For an overview of all standard paper formats, see our paper size guide.

What Size Is A5 Paper?

The dimensions of A5 paper are:

148 × 210 mm

14.8 × 21 cm

5.8 × 8.3 inches

A5 is exactly half the size of A4, and double the size of A6.

The A-series paper system works by halving each sheet while maintaining the same proportions.

For example:

A3 → A4

A4 → A5

A5 → A6

You can explore these neighbouring sizes in our guides to A4 paper size and A6 paper size.

A5 Paper Size in Different Units

A5 paper can be measured in several units depending on the design software or printing setup.

Unit	Dimensions
Millimetres	148 × 210 mm
Centimetres	14.8 × 21 cm
Inches	5.8 × 8.3 in

Using the correct dimensions when setting up artwork helps ensure your design prints accurately.

A5 Paper Size Compared to Other A-Series Sizes

The A-series paper sizes follow a consistent ratio that allows documents to scale perfectly between formats.

Paper Size	Dimension (mm)	Dimension (inches)	Typical Uses
A0	841 × 1189 mm	33.1 × 46.8 in	Large posters, architectural drawings
A1	594 × 841 mm	23.4 × 33.1 in	Posters, technical drawings
A2	420 × 594 mm	16.5 × 23.4 in	Posters, calendars
A3	297 × 420 mm	11.7 × 16.5 in	Posters, menus, presentations
A4	210 × 297 mm	8.27 × 11.7 in	Documents, flyers, brochures
A5	148 × 210 mm	5.8 × 8.3 in	Leaflets, booklets, invitations
A6	105 × 148 mm	4.1 × 5.8 in	Postcards, small flyers

Because the proportions stay consistent, an A5 design can be scaled up to A4 or reduced to A6 without changing the layout.

What Is A5 Paper Used For?

A5 is widely used for small promotional materials and compact printed items.

Common uses include:

Leaflets and flyers
Booklets and small brochures
Invitations and greeting cards
Event programmes
Small notebooks

Because A5 is easy to hold and distribute, it is a popular format for marketing materials and handouts.

For larger printed materials such as posters and presentation graphics, A3 and A4 are more commonly used.

A5 Paper Size in Printing

In commercial printing, A5 is commonly used for leaflets, folded brochures and small promotional materials.

Many designs are created by folding an A4 sheet in half, which produces two A5 pages.

When preparing artwork for A5 printing, designers should ensure the document is set to the correct size and include bleed if the design runs to the edge of the page.
