Which poster size should you choose for your interior?
This is the question that comes up most often, both at my stand and in private messages: "I'm not quite sure which format to pick." It's completely normal. It's hard to visualize what it will look like before you actually hold it in your hands. Here are a few concrete benchmarks to help you choose the right poster size for your space.
The A4 format: the everyday choice
The A4 format (21x30 cm) is the most accessible, and not just because of the price. It's a universal poster size: compatible frames can be found everywhere, at any price, and in all colors. No need to overthink it.
It's the ideal size for an entryway, a hallway, a home office corner, or a shelf. It's also the natural choice for a first purchase when discovering the collection and wanting to test it out. And it's the format that lends itself best to a gallery wall: two or three A4 posters grouped together around places that marked your summers creates a true home gallery.
The 30x40 cm format: when the poster claims its space
With the 30x40 cm size, the poster makes its presence known. Illustration details become fully visible, and the colors have more room to breathe. This format deserves a wall, a real dedicated spot in a room.
This is the poster size I recommend for a living room or a bedroom, when you already know which location you want to highlight. A 30x40 often stands beautifully on its own. It also makes an ideal naturist gift: striking enough to make an impact, yet sober enough to fit into any interior.
The 50x70 cm format: the poster as a central piece
The 50x70 cm size is a whole different scale. A large section of wall, a room where the illustration becomes the visual center of gravity. This format isn't just placed; it is installed. It requires a true decorative commitment, and it rewards you tenfold when the space lives up to it.
The B1 format (70x100 cm): total immersion
For the Ile du Levant poster and the Cap d'Agde naturist village poster, the B1 format (70x100 cm) is designed for enthusiasts who want to treat themselves to a true window looking out onto their holidays. It's an exceptional piece, a monumental format that dresses a wall all on its own and instantly plunges the room into the sunny atmosphere of the location.
Think about the wall before thinking about the format

The most common mistake is choosing a poster size without measuring the available space. An A4 gets lost on a large empty wall. A 30x40 suffocates on a wall that is already cluttered. Before ordering, I recommend grabbing a tape measure, checking the area, and taping a piece of cardboard of the desired dimensions to visualize the result. Two minutes that save you from any regrets.
