Printing is often taken for granted, but sometimes you need to print something very specific, moving beyond the standard A4 sheet. This often leads to questions about paper sizes, like “Is A3 bigger than A4?”. The world of paper sizes can be confusing, especially since the numbering system works in reverse – smaller numbers indicate larger paper dimensions.
To clarify these common questions, we’ll explore various paper sizes, focusing on the ubiquitous A4 print size, its dimensions, uses, and why it’s the go-to standard around the world.
Decoding A-Class Paper Sizes
Paper comes in different classes, and the A-class is what most of us use daily. A-class paper is based on a clever ratio: each size can be folded in half to create the next smallest size perfectly. This systematic approach makes it incredibly convenient and efficient.

Let’s delve into the specifics of each A-size, highlighting their dimensions and typical applications, with a special focus on A4 print size.
A0: The Largest Format
Despite its low number, A0 is the largest in the A-series, measuring a substantial 841 x 1189 mm (33.1 x 46.8 inches). Imagine sixteen A4 sheets combined – that’s the size of A0! It’s primarily used for large-scale applications like architectural drawings, oversized posters, and display boards where maximum visual impact is needed.
A1: Large Posters and Displays
Stepping down in size, A1 paper measures 594 x 841 mm (23.4 x 33.1 inches). Still considerable, A1 is ideal for creating eye-catching posters, window displays for retail, and impactful signs. It offers a significant visual presence without being as massive as A0.
A2: Notices and Art Prints
A2 paper size comes in at 420 x 594 mm (16.5 x 23.4 inches). This size is well-suited for medium-sized posters, notices, art prints, and window displays. It’s noticeably larger than standard newspaper broadsheets, providing ample space for visual and textual content.
A3: Presentations and Charts
You’ve likely encountered A3 paper at work or school. Measuring 297 x 420 mm (11.7 x 16.5 inches), A3 is comparable in size to a tabloid newspaper, though with slightly different proportions. Popular for posters, presentations, charts, and plans, A3 offers a larger print area than A4, making it excellent for visual aids and documents requiring more space. Many business inkjet printers, and even some home models, offer A3 printing from a machine designed for A4, adding to its versatility.
A4: The Everyday Standard
Here it is – the star of the show! A4 print size measures 210 x 297 mm (8.3 x 11.7 inches). This is the most common and recognized paper size globally, particularly in the UK and many other countries. A4 is the workhorse of everyday printing. From simple Word documents and reports to letters, stationery letterheads, and invoices, A4 is the universal format for home, office, and academic printing. Virtually all laser and inkjet printers, including mobile printers, are designed with A4 print capability as a standard feature.
A5: Flyers and Booklets
Moving smaller, A5 paper size is 148.5 x 210 mm (5.8 x 8.3 inches). Half the size of A4, A5 is incredibly practical for flyers, invitations, booklets, planners, and diaries. Its portable size makes it convenient for handouts and personal documents. Many standard home printers can easily print A5, often allowing two A5 prints on a single A4 sheet, maximizing efficiency.
A6: Postcards and Leaflets
Standard A6 paper size is 105 x 148.5 mm (4.1 x 5.8 inches). While too small for lengthy text documents, A6 is perfectly sized for flyers, postcards, leaflets, and save-the-date cards. Some mobile printers support A6 printing, making it useful for on-the-go, small-format print needs.
