Interior designs that incorporate the Rule of Three

The Rule of Three is a design principle that is widely practiced and known by designers globally. It dictates many design aspects of your home: layout, size, and shape of objects, even the color, patterns, etc.

Some would argue that ‘two is better than one and a pair/even number looks complete and balanced. However, the Rule of Three was implemented due to the fact that an odd number of items look more natural and less forced than an even-numbered grouping.

What is the logic behind this? Well, mostly because too much symmetry makes a room look stale and cold (although, we all know symmetry plays a huge role in the design, too). Essentially, there is a balance to be found between symmetry and asymmetry, so there is no right or wrong. Just preferences.

Colour Story

Advised by some interior experts, there is a standard equation that works best when selecting your set of colours. All you need to do is follow the rules of — 60, 30, 10.

Here is what a good colour scheme would look like:

  • 60% being the main room colour
  • 30% being the secondary colour
  • 10% being the accent colour

Take the kitchen in the picture for example – 60% may be a dark grey, 30% may be marble finishing, and 10% could be wooden accents. This combination consists of neautral timeless shades that promotes a more calming room design. If you are into bold colours, there is always the option for pops of colour, so long it sticks within your colour story.

Just be mindful that any more than your colour story will make your interior messy and confusing.

Either way, if you follow the rule of three when choosing colors, then you are guaranteed to achieve a room that is well-designed and welcoming.



How many lighting can one have in a room? Three, of course! Now, it does not mean that the interior should only have three lights in it, rather it simply means that you can play with three different styles of lighting. It could be lamps, pendant lights, spotlights, LED lights, etc.

Preferably, the basic standard for a well-lit interior is dictated by one main ambient light, task lighting (such as side table lamps and spotlights), and then accent lights. All of these layered light sources gel to create a balanced and attractive room.


Artwork and Decorations

Which of these combinations look better?

All works of art possess some form of visual balance. However, there is always the right number of art that goes cohesively together.  That the two pictures for example, the same art, different groups. Though object pairs are often deemed as the perfect symmetry, in this case, a group of three governs a more comfortable visual balance.



Have you ever seen a one-colour room like this brown bathroom in the picture and while it seems like its just one colour, you’d soon notice that its not really all-brown. As a matter of fact, you will see numerous shades of amber, tan, hickory, beige and black. You will also notice 3 main textures—wood, marble and matte. The perfect amount of textures combine within this bathroom offers a cohesive visual treat!


Now that we have hammered this rule into your head, we are going to take a step backward and tell you not to take it too religiously. So do not go around your home creating a museum of three. The rule of three is a guideline that can be bent.

Essentially, the rule was implemented so that people could see that an odd-number of items is more interesting than an even number of items.  So, yes, there are a few home styling and arrangements that welcome 5 items or 9 items into a grouping, yet able to achieve the same visual interest. So don’t be scared to mix it up and have fun.
