Choosing the right poster size often determines whether a room feels harmonious or a bit "empty." Many people order posters that are too small for the wall or surrounding furniture – and then much of the desired effect is lost.
Fortunately, there are some simple rules of thumb that make choosing the right size much easier. Here's a simple guide to help you find the poster size that best suits your home.
First, consider the furniture below
A good interior design rule is that wall art should be approximately 60–75 percent of the width of the furniture below it. For example, if you have a 200 cm sofa, a poster or gallery wall around 120–150 cm wide will look most balanced.
You can achieve this in several ways:
-
one large poster
-
two medium-sized posters
-
a gallery wall with several smaller posters
Many people today choose to combine several sizes to create a more vibrant expression.
The most popular poster sizes
There are many sizes, but some are common in most homes.
21x30 cm (A4)
Perfect for small shelves, office spaces, or as part of a larger gallery wall.
30x40 cm
A very popular size that works well alone on smaller walls or combined with other posters.
50x70 cm
One of the most used sizes for living rooms and bedrooms. Large enough to be a focal point, but still easy to combine with other posters.
70x100 cm
This is a statement poster. It works perfectly alone above a sofa, bed, or dining table.
Above the sofa
The wall above the sofa is often the natural place for art. Here, it's important that the poster isn't too small.
A poster measuring 50x70 cm or 70x100 cm often works best. Alternatively, you can create a small gallery wall with three or five posters of different sizes.
This adds more life to the room and makes the wall a natural focal point.
Above the bed
In the bedroom, many desire a calm ambiance. Here, it works well with:
-
one large poster at 70x100 cm
or -
two posters at 50x70 cm
If you hang two posters, there should be approximately 5–10 cm of space between them to create balance.
Create a gallery wall
A gallery wall is one of the most popular ways to use posters today. Here you can combine different sizes to create a more personal expression.
A classic combination is:
-
1 poster 50x70 cm
-
2 posters 30x40 cm
-
2 posters 21x30 cm
This provides a nice variety without making the wall feel cluttered.
Remember the distance to the floor
When hanging posters, the center of the motif should usually be around 145–155 cm from the floor. This is approximately eye-level and makes the picture feel natural when entering the room.
If you hang the poster above a piece of furniture, there should be 10–20 cm between the furniture and the frame.
A final tip
If you're unsure about the size, it's almost always better to choose a bit larger than a bit too small. Large posters create more impact and give the room a more cohesive look.
At Plakatbar, you'll find posters in various sizes that can easily be combined to create both large gallery walls and small personal corners in your home.
The right size can make all the difference – transforming an empty wall into a natural focal point in the room.
