Thirty square meters, four meters to the roof ridge, and, since December 1, 2025, not even a notification to the municipality. In twelve years, the tiny house has gone from a niche solution to Sweden’s most common way to get an extra room, and 2026 is the first full year under the new rules, which eliminate processing fees of up to SEK 20,000 and allow 50 square meters outside detailed development areas. But anyone who has put a newly built tiny house on their property and is looking for a poster for it quickly discovers a problem no house manufacturer mentions: the walls. A small house has few walls, most are broken up by windows, doors, and a loft, and the only truly clear space often ends up behind a sofa bed. The right poster on the right wall is what determines whether the house feels like a home or a well-insulated storage shed. This guide covers what works in 30 square meters, from the loft wall to the short wall behind the kitchen counter.
Quick facts: The tiny house was introduced in July 2014, named after then housing minister Stefan Attefall, with a limit of 25 square meters. Since August 2020, the limit has been 30 square meters, and on October 22, 2025, the Riksdag passed bill 2024/25:169, which, starting December 1, 2025, removes the notification requirement entirely, raises the limit to 50 square meters outside detailed development areas, and introduces a freely allocated permit-exempt allowance of 45 and 65 square meters, respectively. The maximum roof ridge height is still 4.0 meters, and the distance to the property boundary must be at least 4.5 meters.
Why 30 square meters put completely different demands on the walls than an apartment
A tiny house isn’t a small apartment. It’s a house where all the functions share the same space, and that changes how a poster is experienced. In a standard apartment, you see a picture from one angle, at one distance. In a tiny house, you see the same picture from the bed, the kitchen counter, the sofa, and the loft, often from less than three meters away. A print that holds up to close viewing, with details that reward a second look, beats one that only works from a distance.
Light is the other thing that makes a difference. Most tiny houses from major manufacturers have large windows at the gable end or along one side to compensate for the limited space, creating strong side light that sweeps across the walls throughout the day. Shiny glass surfaces and dark, glossy prints reflect the window and become hard to read at certain times. Matte paper, lighter prints, and placing the art on a wall that doesn’t face the window directly solve most of the problem.
The third factor is ceiling height. The ridge height can be no more than four meters, and in a house with a loft, that means the sleeping area often has 1.2 to 1.6 meters of headroom. You don’t hang anything large there. But the open area under the ridge, often 3 to 3.5 meters up to the ceiling, is the only space in the house that can accommodate a truly large format, and it’s almost never used. Read our guide to art for sloped ceilings, where the same principles apply.
Three accessory dwelling units, three different walls: the guest cottage, the office, and the rental
What the house will be used for determines the print, and accessory dwelling units practically fall into three types. The guest cottage, which mostly stands empty and is meant to host family and friends for a few weeks a year, is best suited to prints that feel welcoming without being personal: landscapes, sea, forests, or a botanical print connected to the garden. Think of it as a hotel room you’d want to wake up in yourself. We’ve written more about that approach in our guide to prints for the guest room, and the principle is the same, just with even less space.
The garden office has become the fastest-growing use since the pandemic, and here the opposite applies: the print can be personal, but it should be calm. You sit in front of the same wall eight hours a day. Abstract prints in muted colors, graphic line drawings, and architectural prints of cities you like work better than striking portraits or text prints with messages that get tiresome by the third week. Place the picture behind your screen so it shows up in video meetings; in an accessory dwelling unit, the background in the frame is often the entire house.
The third type is the rental. With the new rules, 30-square-meter accessory dwelling units have become a common investment, and here the poster is part of the listing image. Bright, colorful prints that stand out in the thumbnail on the booking site, preferably with a local connection such as a poster featuring well-known nearby places, give the house an identity in the feed. Find out more about what attracts bookings in our rental buying guide.

Prints that make the house feel bigger: horizons, forests, and calming colors
There are a few visual tricks that work especially well in a small space. The first is the horizon. A landscape with a low horizon line, a beach, an open mountain expanse, or a sea gives the wall a depth that an abstract image cannot. The eye reads the image as a window, and the house feels a little bigger than it is. Bozetto’s nature prints are the obvious place to start, especially the Nordic landscapes that work with what you see through the window.
The second is color. Light walls are standard in Attefall houses because they make the room feel airier, and a poster in a similar light tone, sand, chalk white, soft gray-green, extends the wall rather than breaking it up. Minimalist posters with plenty of white space around the subject are the safest choice for anyone worried the house will feel cluttered. If you want color, concentrate it in a single picture and let the rest of the walls rest.
The third is the botanical connection. An Attefall house stands in a garden, and a picture featuring plants, leaves, or flowers ties the interior to what you see through the door. Posters with floral motifs in muted colors work in the guesthouse all year round, while more graphic leaf designs suit an office. Pinterest’s trend report for 2026 also shows that searches for cozy reading chairs for small spaces have increased by 455 percent and searches for reading nooks for adults by 55 percent; the little reading nook in an Attefall house is exactly where a botanical poster does the most good.
Size and placement in a house with a loft, sofa bed, and a 4-meter roof peak
Measure the walls before you buy. A typical 30-square-meter Attefall house has an interior width of about 3.5 to 4 meters and a length of 7 to 8 meters. The gable wall beneath the roof peak, if it has no windows, is the house’s largest uninterrupted surface and can accommodate a 70 × 100 centimeter print, or two 50 × 70 pictures hung one above the other to follow the upward slope of the roof. It’s the only place in the house where a large format makes the room feel taller rather than more cramped.
The long wall behind the sofa or bed is usually interrupted by windows, and 50 × 70 in landscape orientation works best there, hung so the center of the picture sits about 145 centimeters above the floor. If you have a sofa bed that folds out, the bottom edge of the picture needs to be at least 15 centimeters above the backrest; otherwise, the pillows will hit the frame every evening. The short wall by the kitchen, often with 60 to 90 centimeters of clear wall between cabinets and a door, is made for 30 × 40 in portrait orientation; it’s Sweden’s most commonly used poster size for a reason, and our separate buying guide for 30 × 40 takes a closer look at the format. All sizes are gathered in our collection of 30 × 40 centimeter posters.
The loft at last. With 1.2 to 1.6 meters of headroom, you won’t hang anything large, but a small 21 × 30 picture on the gable wall next to the pillow, at eye level when lying down, is what makes the loft a bedroom instead of a shelf. Choose a calm subject without strong contrasts; it’s the last picture you see before you fall asleep.
Tip: Newly built Attefall houses have plasterboard or paneled walls with studs spaced 60 centimeters apart. Locate a stud by knocking and screw into it if the picture is large; on a paneled wall, you can screw anywhere. For a rental or guesthouse that's unheated for part of the year, avoid adhesive hooks; they come loose when the temperature fluctuates. A screw and a frame with matte glass or acrylic can withstand both the cold and side lighting.
Cold in winter, warm in summer: how to protect a poster in a house that isn't always heated
An Attefall house used as a guesthouse is often kept at a lower temperature from October to April. Moisture isn't the problem; modern houses are well insulated. Instead, it's the temperature fluctuations when the house is heated before a visit. Paper expands and contracts as humidity changes, and a poster tightly fitted in a frame without a mat can warp after a winter. The solution is simple: a frame with a mat gives the paper room to move, and an acid-free backing protects against yellowing edges. The same advice applies to a summer house, and it's worth following from the very first winter.
Summer brings the opposite problem. Large windows let in direct sunlight for several hours, and colorful prints near the window fade faster than they would in an apartment. If you hang colorful pictures, place them on the wall at an angle to the window, not opposite it. Black-and-white photographs and graphic line art are resistant to fading, making them especially suitable for the part of the house near the window. For the best spots, such as the gable wall under the roof ridge, muted colors, matte paper, and a frame with glass are the combination that lasts longest.
One last practical tip: an Attefall house is often delivered move-in ready and furnished in a weekend. Wait a week before putting anything on the walls. Live in the house, see where the light falls in the morning and evening, and then buy three pictures at once: one large one for the gable end, a landscape-format one for the long wall, and a small one for the kitchen or loft. Three prints in the same color palette make a 30-square-meter house feel more cohesive than ten different pictures ever could.

Frequently asked questions about posters in Attefall houses
The Attefall house is the only room in Sweden that has been made larger by a parliamentary decision, but it’s still the walls that determine how big it feels. Choose an image with a horizon for the gable end, a calm one for the long wall, and a small one for the loft, all in the same color palette, and the thirty square meters will start to feel like a home instead of a shed with a bed. Start with our collection of posters of famous places if the house will be rented out, or with nature prints if you’re the one who’ll wake up there.
