A5 Size in Pixels: Exact Size, DPI & Uses

A5 Size in Pixels: Exact Size, DPI & Uses

Have you ever tried setting up a blank canvas in Photoshop, Procreate, or Canva, only to freeze the moment it asks you for the exact pixel dimensions? If you are designing a flyer, a bullet journal, or a little booklet, you’re probably aiming for A5 size.

But here is the frustrating part about digital design: unlike physical inches or centimeters, pixels don’t have a fixed, real-world size. They shapeshift depending on how densely they are packed together. (If you ever want to skip the math entirely, you can always just use our A-paper size in pixels converter to get the exact numbers instantly).

If you just need the quick numbers so you can get back to creating, skip down to the Cheat Sheet at the bottom. But if you want to understand exactly why your screen looks different from your printed copy, let’s break down the exact size of A5 in pixels, how DPI works, and what this handy paper size is actually used for.

What is A5 Size, Anyway?

Let’s start with a real-world analogy. Imagine a standard, everyday piece of printer paper—the kind you use for school essays or office memos. In most of the world, that’s an A4 sheet.

Now, fold that piece of paper perfectly in half, hamburger style. Boom. You’re holding an A5 sheet.

In physical measurements, A5 is exactly:

• 148 x 210 millimeters

• 14.8 x 21 centimeters

• 5.8 x 8.3 inches

It is the Goldilocks of paper sizes: big enough to hold a good amount of information, but small enough to comfortably hold in one hand or tuck into a small bag.

The Pixel Problem: Why DPI is Your Best Friend

So, how does a physical piece of paper translate into digital pixels? This is where people usually get tripped up. The answer depends entirely on your DPI (Dots Per Inch) or PPI (Pixels Per Inch).

Think of DPI like the thread count of a bedsheet. A 72-thread-count sheet (72 DPI) is going to feel rough and look a little cheap, but it gets the job done if you’re just throwing it over a piece of furniture to keep the dust off. On the other hand, a 300-thread-count sheet (300 DPI) is dense, high-quality, and crisp.

When you pack more pixels into the exact same 5.8 x 8.3-inch space, the total number of pixels skyrockets.

• If you are designing for the web (72 DPI): You don’t need a massive thread count. Screens display things beautifully at lower densities.

• If you are printing (300 DPI): You need high density. If you try to print a 72 DPI image, the printer has to stretch those few pixels out to fill the page, leaving your design looking blurry, blocky, and completely pixelated.

The Exact A5 Pixel Dimensions

Here are the exact numbers you need to punch into your design software, depending on what you plan to do with your final image.

1. High-Quality Print (300 DPI)

• 1748 x 2480 pixels
  If your design is going to leave a physical printer—whether you’re making a wedding invitation, a zine, or a promotional flyer—always use 300 DPI. It guarantees crisp text and sharp images.

2. Medium Quality / Draft Print (150 DPI)

• 874 x 1240 pixels
  This is a great middle ground if you are printing something out just for yourself to proofread, or if your computer is running slow and struggling to process a massive 300 DPI canvas.

3. Web & Screen Only (72 DPI)

• 420 x 595 pixels
  Use this only if your design will never, ever be printed. This size is incredibly lightweight, meaning it will load instantly on a website or in an email, but it will look like a blurry mosaic if you try to put it on paper.

What is A5 Actually Used For?

Because of its incredibly convenient “half-page” size, A5 is a powerhouse in both the publishing and marketing worlds. It doesn’t overwhelm the reader, but it provides plenty of real estate for beautiful layouts.

You see A5 everywhere in the wild, even if you don’t realize it:

• Novels and Books: Pick up a standard paperback off your shelf. Chances are, it’s roughly A5 size.

• Journals and Planners: Almost all popular bullet journals (like the famous Leuchtturm1917) and daily planners use the A5 format because it fits perfectly on a desk or in a tote bag.

• Event Flyers: When promoters hand out flyers for concerts, club nights, or local businesses, they are usually A5. It’s cost-effective to print (you get two per A4 sheet!) and easy for people to hold onto.

• Zines and Booklets: Indie creators love A5 for self-published magazines and comic books.

Best Used For	Exact Dimensions	Measurement Type
Physical rulers & European print shops	148 x 210 mm	Millimeters
US designers visualizing physical space	5.8 x 8.3 in	Inches
High-quality professional printing	1748 x 2480 px	300 DPI (Pixels)
Draft printing & reducing file size	874 x 1240 px	150 DPI (Pixels)
Web use, emails, and screens only	420 x 595 px	72 DPI (Pixels)

Final Tip: When in doubt, always start your project at 300 DPI (1748 x 2480 pixels). It is incredibly easy to shrink a large image down for the web later, but it is completely impossible to magically add pixels to a small image to make it print-ready!
