Have you ever spent hours designing a gorgeous flyer or invitation, only to hit print and stare at a blurry, pixelated mess? Yeah, we’ve all been there.
Figuring out exactly how big your digital canvas should be can feel like you need a math degree. If you’re trying to set up a document for A6 size and you’re staring blankly at the “width” and “height” pixel boxes in Photoshop, Canva, or Figma, take a breath. I’ve got you covered.
Let’s break down exactly what size you need, without the confusing jargon.
Visualizing A6 (Without a Ruler)
Let’s step away from the screen for a second. How big is A6, really?
Grab a standard piece of printer paper (that’s A4). Fold it in half. Now fold it in half one more time. Boom—you’re holding an exact A6 piece of paper.
In physical measurements, it sits at roughly 4.1 x 5.8 inches (or 105 x 148 millimeters). It’s basically the exact dimensions of a standard postcard or one of those little pocket-sized Moleskine notebooks. It’s small, incredibly handy, and the undisputed champion for quick handouts, event invitations, and thank-you cards.
The “Thread Count” Secret: Why DPI is Everything
Here’s where people usually get tripped up: there isn’t just one pixel size for A6. The number of pixels you need depends entirely on what you plan to do with the design once it’s finished. This all comes down to DPI (Dots Per Inch) or PPI (Pixels Per Inch).
Think of DPI like the thread count on hotel bedsheets.
A low thread count (like 72 DPI) is perfectly fine if you’re just looking at it from across the room—or in digital terms, viewing it on a computer screen. It looks great on a monitor, but if you try to print it out and hold it up close? It’s going to look “scratchy,” blocky, and completely out of focus.
A high thread count (like 300 DPI) is luxurious, smooth, and crisp. That’s exactly what you need for physical printing. More dots per inch means more detail, which inherently means you need a much higher pixel count to fill the same physical A6 space.
The Magic Numbers for A6 in Pixels
Alright, let’s get down to business. Here are the exact pixel dimensions you need to type into your design software.
1. Printing it out? (Use 300 DPI)
If your design is going to live in the physical world—coming out of your home inkjet printer or heading off to a professional print shop—you must use 300 DPI.
-
Width: 1240 pixels
-
Height: 1748 pixels
(Pro-tip: If you’re sending this to a professional print shop, they usually want a “bleed” area. That’s an extra little printed border so they can trim the paper cleanly without leaving awkward white edges. If they ask for a standard 3mm bleed, you’ll want to bump your digital canvas size up to roughly 1311 x 1819 pixels).
2. Keeping it on a screen? (Use 72 or 96 DPI)
If you’re designing a digital postcard for an email newsletter or a quick promo graphic for a website, you don’t need all those extra pixels. In fact, using a massive file will just slow down your website’s load time. Stick to standard screen resolutions.

At 72 DPI: 298 x 420 pixels
-
At 96 DPI: 397 x 559 pixels
Your A6 Dimension Cheat Sheet
Let’s wrap this up. Here is a quick, screenshot-able cheat sheet you can save for your next design project.
| Format / Resolution | Width | Height |
| Millimeters (mm) | 105 mm | 148 mm |
| Inches (in) | 4.13 in | 5.83 in |
| Web / Screen (72 DPI) | 298 px | 420 px |
| Standard Web (96 DPI) | 397 px | 559 px |
| High-Quality Print (300 DPI) | 1240 px | 1748 px |
Hopefully, this clears up the pixel confusion so you can get back to the fun part: actually designing! If you’re curious about how A6 stacks up against the rest of the family or need dimensions for a different project, check out our complete guide to A paper sizes in pixels.
