All Photo Print Sizes Explained: From 10x15 to Giant Posters

When you print a photo, you give it a second life, whether you add it to an album, hang it on the wall, or give it as a thoughtful gift. But with so many sizes available, the choice can quickly become confusing.

10x15, 13x18, posters, canvas, aluminum... each format has its own purpose. And above all, each format corresponds to a specific intention, a certain mood, or a particular spot in your home or in your life.

Whether you want to capture a vacation memory, decorate a living room, or give a gift that stands out from the crowd, you’ll find everything you need here to make the right choice, from the most classic to the largest formats.

What are the different photo print sizes?

When we talk about photo print sizes, we often think of small prints that we slip into a frame or carefully store in an album. But the reality is much broader than that. From classic prints to large-format posters and prints on premium materials, the possibilities are endless. Here’s an overview.

What are the standard photo sizes?

The so-called “standard” sizes are the ones most commonly found in photo labs and on online printing platforms. They’ve stood the test of time because they meet simple, universal needs.

The most iconic remains the 10x15 cm. In fact, this is the format of an entire generation, the size of the photo development envelopes we used to pick up at the photographer’s shop. Compact, easy to frame, and affordable, it remains a reliable choice for everyday prints.

Next come the 13x18 cm and the 15x20 cm, two sizes that offer a bit more surface area to appreciate the details of an image. People often choose these when they want to display a photo in a frame placed on a piece of furniture or hung in a living space.

The 10x10 cm, on the other hand, is a little different. Square and modern, it has become popular with the rise of social media and the Instagram format. It’s particularly well-suited for close-up portraits and graphic compositions.

Beyond these common sizes, there’s a whole range of larger sizes, up to giant posters, which we’ll discuss a bit later.

A Print Size for Every Purpose

When choosing a size, ask yourself this question: What is this photo intended for ? A print you slip into a wallet doesn’t have the same requirements as a photo you want to frame above a sofa.

A small-format travel souvenir will naturally find its place in an album. A family photo taken during a special moment, on the other hand, might deserve a different treatment, larger, more visible, and more present in your daily life.

Keep in mind that the format also influences how the image is perceived. A landscape-format photo emphasizes width, inviting the eye to wander. A portrait format draws the viewer’s attention more toward the central subject. A square format, on the other hand, imposes a certain symmetry and a more composed framing.

That’s why choosing a format isn’t just a technical decision, it’s also a creative one. It says something about the image you’ve chosen and where you want it to take center stage.

From standard prints to large-format prints: which one should you choose for your project?

Every photo tells a story. But it’s often the chosen format that determines how that story will be perceived. If it’s too small, a photo loses its impact. If it’s too large, it can seem out of proportion in a space that isn’t suited to it. Finding the right balance is the focus of this section.

What is the 10x15 format, and why is it so popular?

The 10x15 cm is undoubtedly the most well-known photo print format of all. For decades, this was the standard size you’d find coming out of photo labs, as mentioned earlier. And even today, it remains the classic choice for photo prints.

Its popularity stems from several factors. It’s easy to handle, easy to store, and compatible with virtually all commercially available frames. Its rectangular format naturally matches the proportions of modern digital sensors, which helps avoid unwanted cropping.

People choose it to fill a family photo book, build a small collection of memories, or give a few prints to loved ones. It’s an everyday, accessible, no-frills format, but one that always makes an impression when the photo is beautiful.

Looking for something larger or more original for a photo print?

Sometimes, a memory deserves a little more space. That’s why the 13x18 cm and 15x20 cm sizes exist.

The 13x18 cm size strikes a nice balance. It offers enough space to appreciate the details of a portrait or landscape without requiring a large wall to display it. This is often the size people choose for a framed photo to sit on a dresser or desk.

The 15x20 cm, on the other hand, takes it a step further. The details have more breathing room, and the colors come through with greater intensity. This size is for those who want to highlight a special photo, the one that really matters, without going as far as a poster.

To meet all your needs, AgfaPhoto Print offers a wide range of sizes: the classic 10x15 cm, ideal for photo albums. The 10x10 cm square format, modern and trendy. The 13x18 cm for a more detailed rendering, and finally the large 15x20 cm format to highlight every detail. Their system automatically detects the format best suited to your image, guaranteeing a harmonious result without any extra effort.

What if the square format is just right for you ?

The square format invites a different way of viewing the image, one that’s more centered and contemplative. You don’t try to scan the frame with your eyes; you pause to take it in.

We’ve touched on this briefly, but the 10x10 cm format has naturally become popular with the rise of mobile photography and social media. Many of our everyday photos are already composed with this in mind: a centered subject, a clean background, and instinctive framing.

It works particularly well for portraits, close-ups, or graphic series that you want to display together on a wall. Several square prints lined up side by side create a simple and elegant gallery effect without requiring a lot of space.

It’s also a format that lends itself well to display. Its unconventional shape gives it a slightly more polished look than a classic rectangular print.

Posters, canvases, aluminum, plexiglass: when a photo becomes decor

There comes a moment when a photo transitions from a memory to an object, when it stops being tucked away in an album and becomes a full-fledged part of your home’s decor. Large formats and premium materials transform an image into a visual statement, something you look at every day that says something about you.

What photo print format should you choose if you want to decorate a wall?

A large empty wall can quickly feel overwhelming in a room. A well-chosen photo, printed in the right format, is sometimes all it takes to change everything.

The photo poster is the simplest and most straightforward solution. Available in portrait, landscape, or square orientations, it comes in a wide range of sizes, from 20x20 cm up to 84x118 cm. It’s a generous format that allows an image to truly shine, whether it’s a mountain landscape, an urban snapshot, or a close-up portrait.

For those who want a more polished look, the framed photo poster adds that extra finishing touch. Available in portrait and landscape orientations, in sizes ranging from 20x30 cm to 100x70 cm, it hangs directly on the wall without the need to search for a compatible frame. This saves time and, above all, delivers an instantly clean and polished result.

Both formats work equally well in a living room, bedroom, hallway, or even a workspace. The key is to choose an image with sufficient resolution to withstand enlargement without losing sharpness.

Which medium should you choose for a premium look and a successful photo print?

When you want to take visual quality even further, the choice of medium becomes just as important as the choice of format. Three materials stand out in particular.

Photos on canvas are undoubtedly the most classic of high-end wall prints. They offer a warm texture and a slightly matte finish reminiscent of a painting. Available in portrait, landscape, and square orientations, in sizes ranging from 20x20 cm to 100x100 cm, they blend naturally into both contemporary interiors and more traditional spaces.

Photos on aluminum are in a league of their own. The metal gives the image striking depth and luminosity. The colors seem to literally shine. Also available in sizes ranging from 20x20 cm to 100x100 cm, in portrait, landscape, and square formats. It works particularly well with high-contrast black-and-white photos or images with vivid, saturated colors.

Finally, photos on Plexiglass take this glossy effect even further. Acrylic glass creates a unique sense of depth, as if the image were in relief behind a smooth, transparent surface. You can choose from portrait, landscape, and square orientations, in sizes ranging from 30x30 cm to 100x100 cm. It’s clearly a medium that catches the eye and leaves no one indifferent.
