Simply put, the rule of three suggests that things grouped in groups of three are more natural, harmonious, and visually appealing. Odd numbers challenge our brain a bit and are more interesting. The Latin phrase “omne trium perfectum” means “everything that comes from three is perfect, or every set of three is complete”. And when it comes to design, that definition fits perfectly.
Our eyes are naturally drawn to groups of three. Designing shelves can sometimes be a challenge, but using the rule of three makes it much easier. Start by placing three items on each shelf, then step back and decide what you need to adjust, if anything. When you layer two objects or stack them, they merge and become a single element.
To add even more interest, vary the height of your accessories and inject a touch of color. To make an impact with a decorative display, the magic number is undoubtedly three. Grouping three objects is a technique that the best interior designers frequently employ to make the objects they collect together a feature that deserves attention.
