Walk into any home, and you can almost feel its personality. Some spaces instantly give you a sense of calm with clean lines and natural light. Others feel warm, layered, and filled with stories. That’s the magic of interior design styles—they shape how a house feels, not just how it looks.
Thank you for reading this post, don't forget to subscribe!But here’s the tricky part: there are dozens of styles, rules, and trends. You might hear about the 7 basics of interior design, the 3-5-7 rule, or the 2/3 proportion trick and wonder how all of it fits into your own living room. Don’t worry—you’re not alone. This guide is going to break things down in plain language, no fluff, no jargon.
What Kinds of Interior Design Styles Are There?
Interior design is like fashion—it comes in many flavors. The most common include:
-
Contemporary interior design → clean, trendy, light-filled.
-
Modern interior design styles → open spaces, sleek furniture, little clutter.
-
Classic interior design styles → elegant, timeless, with symmetry and details.
-
Industrial → exposed brick, raw metals, urban vibes.
-
Bohemian → layered, colorful, anything-goes.
-
Rustic/Farmhouse → cozy, natural wood, comfort first.
-
Transitional → a mix of traditional warmth and modern simplicity.

What Are the 7 Basics of Interior Design?
Every great space—whether it’s a modern loft or a classic family home—leans on these fundamentals:
-
Balance (symmetry or intentional asymmetry).
-
Harmony (everything feels like it belongs).
-
Rhythm (patterns or repetition that guide the eye).
-
Proportion and Scale (big pieces in big rooms, small in small).
-
Emphasis (a fireplace, a chandelier—something that stands out).
-
Contrast (mixing textures, colors, shapes).
-
Details (pillows, knobs, lighting—tiny touches that matter).
Without these, even the best furniture won’t feel right.
The 3-5-7 Rule in Decorating
Ever notice how odd numbers look more natural than even? That’s the 3-5-7 rule in action. Designers often group items—candles, pillows, wall art—in threes, fives, or sevens.
Example: three vases of different heights on a dining table instantly feel styled, while two may look awkward. This small trick works across modern interior design styles and classic interiors alike.
The 2/3 Rule in Interior Design
Another favorite rule is the 2/3 proportion. It simply means things look more balanced when one element takes up about two-thirds of the space.
-
A sofa that’s two-thirds the length of the wall.
-
A rug covering two-thirds of a floor area.
-
A painting that spans two-thirds of the console beneath it.
This keeps a room visually balanced without overthinking it.
