You've found the perfect poster. But then comes the next question: what size should I choose?
Too small and the poster will get lost in your interior. Too big and it quickly feels cluttered. Luckily, choosing the right size doesn't have to be difficult at all. In this guide, we'll explain exactly which poster sizes best suit your wall, living room, bedroom, or office.
Why the right poster size is so important
The size of your wall decor largely determines the look and feel of a room. A poster that is too small on a large wall quickly looks lost, while a large size can exude tranquility and luxury.
A good rule of thumb: wall decor should take up approximately 60% to 75% of the available wall width. This creates balance.
