Ready to transform your home? These are the 5 of the basic decorating rules you should follow according to interior designers.

If you were to do any research, you’d find that good interior design has the power to make a space feel more compelling and to amplify your experience in it.

Decorating rules exist for a very important reason, which is to help us make decisions for our home that will turn it into a place that’s comfortable and pleasing to live in.

Great design reaches beyond making a room feel or look good. A well designed room is also a well functioning room.

So, keep in mind that decorating rules don’t exist to dictate the choices that we make, but rather to guide us into making choices that will help our home look its best.


The rule of 3 is so important that it affects just about every aspect of every room in your home! You might even say it’s the golden rule or golden ratio of interior design.

In it’s technical form, it applies to a room’s layout, the size and shape of objects and a kitchen’s work triangle. It even applies to the number of colors, patterns and fabrics.

If you’re already familiar with the term, you may have heard it used most often in reference to arranging vignettes in groups of 3 items.

I prefer to call it the rule of odds. There’s just something more appealing to the senses when items are arranged in odd numbers. Three seems to be the most often used number, but groups of 5, 7 or 9 work well too, depending upon the type of arrangement.

Think about a coffee table or side table, for instance. An arrangement of an odd number of items, grouped together is much more appealing to the eye than 2 or even 4. Experiment with a vignette of your own to truly see the impact.


I’m talking about space planning. Careful and well thought out space planning may not sound like a fun thing to do, but it’s very necessary.

Not only will it allow you to utilize every nook and cranny in a room, which is especially important in a small space, it will improve both traffic flow and functionality.

For example, you may dream about having two sofas that face one another with a coffee table between them, but that may not work in your space.

I would love to do that in my family room, and even though I do have the room to do it, it would not work for us at all. We would lose the walkways that currently exist going from our hallway and foyer into our kitchen.

There are three different ways you can tackle space planning besides doing it the hard way of physically moving your furniture around:

METHOD 1: Measure your room and draw it out on a piece of graph paper. Measure each piece of furniture, that will be in the room, then cut out pieces of cardboard or paper to represent each one. Keep the proportions of the furniture pieces the same as the proportions on the graph paper.

Let’s say the squares on your graph paper are ¼” and that each square represents 12″ (or 1′) of space. When cutting out your pieces of furniture, if you have a chair that measures 36″ wide, your little piece of cardboard (or paper) should be ¾” wide. Make sense?

Once you have your room drawn out and have your pieces of furniture, you can move them around on your graph paper until you come up with a furniture arrangement that you like.

METHOD 2: Measure the furniture pieces that will be in the room and use painter’s tape on the floor to represent each piece. This is a little more labor intensive, but it gives a better feel for how the pieces will work in a room.

This method worked especially well for us when we completely gutted and remodeled our kitchen.

METHOD 3: Prefer to do your planning on a computer? There is a variety of free space planning software available on the web. Just Google, “free space planning software” and you’ll be presented with lots of options.


This goes hand-in-hand with Rule #2. You can’t do a good job of space planning until you’ve determined the focal point of your room.

A focal point can be something as obvious as a fireplace or tv, but it can also be a window, a large piece of furniture, a furniture grouping, an architectural detail – anything that catches your eye as soon as you enter a room.

A room can also have multiple focal points, which can be a real challenge. I’ve talked about this in greater detail (with loads of tips!) in a previous blog post. I highly recommend taking these tips into consideration when doing your space planning!


Choosing rugs and fabrics is especially true if you are painting any part of your room a color. Paint comes in thousands upon thousands of colors. You can even have paint custom mixed to match a single color in your fabric.

The reason that I take this step, before choosing my paint color(s), is that finding paint to go with a particular fabric or rug is a whole lot easier than finding fabric or rugs to go with a particular paint color.

The rule applies to rooms painted with a neutral color as well. Why you ask? Well, every single paint looks different in different lighting situations.

Most neutral paints, including white, have undertones of other colors in it. Ever seen a beige room that looks pink or lavender when the sunlight hits it? Yeah, that’s what I’m talking about.


This falls into the category of less is more – but then again, it all depends upon your point of view. Many people prefer a very minimal look, so for them a lot less is more and that’s perfectly fine.

That isn’t me at all though. I enjoy having pretty things in my rooms, but I do strive to strike a balance between too much and just right.

If you’re like me and prefer to have lots of pretty things around to look at, just be careful not to go overboard or you’ll wind up with a room filled with so much stuff, your eye won’t know what to look at first.

I’ve always heard that when you’re adding jewelry to your outfit, you should add what you think will look good and then remove one thing. So I guess, the rule of thumb is to edit, edit and then edit some more.


There are no rules. Well…technically speaking, there are decorating rules, but if I don’t like a rule – I’d don’t follow it.  Seriously.

This is my home, not some designer rule setter’s home, and I’m going to do what works for my family and myself, whether it follows the rules or not.  My #1 recommendation for you is that you develop the same attitude!

However, with that being said, let me also say that although I’ll break a rule if I don’t like it, I do try to follow certain design principles.  No matter what the latest trend may be, these principles have been around for a long, long time and they just plain work.

In conclusion – you may not like to think of yourself as a rule follower, but when it comes to decorating your home, you’ll be glad that you at least followed these basics.



There are 3 basic ways to get started:

· Choose a color you love as a starting point.

· Use a color wheel to choose complimentary colors.

· Test your choices in the room together.

· Buying everything at once. Take your time instead.

· Hanging art too high for its location, which can make a room feel off balance.

· Choosing the wrong paint color. Always test swatches on your wall instead of purchasing paint based on the paint chip sample.

There’s no hard rule that says you should stick with one style. Mixing styles can create a lot of interest. If you do choose to mix styles, just be sure that some cohesiveness to the overall design, such as patterns, decorative elements, colors.

  1. I am going to pin this post and re-read this everytime I start a project in a room. The kitchen is this spring. Thank you for inspiring me.

  2. Definitely rules I live by too. Less is more- trying to decide now whether to add decor above kitchen cabinets- no greenery though! Ceilings 10 feet- have about 18″ above cabinets…

  3. Editing is tough but a good reminder that you

  4. Thank you for these common sense suggestions. Clutter makes me crazy so I am constantly editing. I love the candle holders on the buffet in the picture of your dining room. Do you mind to share where you found them?

    1. Hi Jeannie. Those candle holders came from Pottery Barn.

  5. Love your approach to decorating.

  6. Carol Elkins says:

    I love Rule #1! Thank you for sharing these great tips.

  7. Fabulous tips Suzy. I love the use of the word “principles” rather than “rules”. I have found taking a picture of a room helps as well when deciding whether or not to add or take away decor items. Sometimes it’s good to take a step back and look at the overall feeling of the room. A picture helps tremendously.

  8. Brenda Radliff says:

    Thank you very much for these awesome tip!! I love your style!! Beautiful.

  9. “You don’t have to fill every space.” That is a GREAT rule to NEVER, NEVER break. Thanks!

  10. These are really great rules. The paint situation is one that I have had to deal with. I bought a sand colored paint which now looks lavender in the sun. And for some reason even when the sun is not shining on it, I am stuck with that image.

  11. Tina Sipe says:

    I love the fabric on your two buffalo plaid chairs. I’m looking for the exact fabric to recover an antique chair that was my parents. Can you share where you found it?

    1. Hi Tina. I found the fabric at Printer’s Alley fabric store. 😀

  12. Sara @ finditfixitorbuildit.com says:

    Great ideas, thanks for sharing!

  13. Suzy, great tips! I, too, love to sketch and play with the paper cutouts before I assemble the room or part of the room! And I also agree that it is way easier and more practical to choose paint matching your fabrics than vise versa! Thank you for sharing. Your house looks beautiful and balanced!

  14. I enjoy having a lot of pretty things (that are also sentimental in my rooms also) so thanks for reaffirming that I need to keep that in mind when editing the different areas of my home.

    1. Love the rules , you make it easy to decorator you are very espiring.

  15. Yes, I learned the hard way about paint looking different in different rooms. You are so right on that, try a little bit and see how the sun shine es in there, etc…

  16. Denise Hill says:

    Thank you for the great tips! We just bought a new house, and are decorating room by room. This was just what I needed!

  17. Denise Mercer says:

    Using graph paper to plot out furniture placement in advance was a lifesaver (or muscle-saver) for me when I was planning a room with a heavy furniture piece. My husband was grateful.

  18. I love your decorating style! I’m keeping this article to read before I tackle a room re-do.

  19. Love your living room, so inviting. Good basic rules to follow.
    Love the way you keep changing your accessories for each season!
