Decorating a living space isn’t as simple as it sounds. From choosing paint colors and furniture you’ll love for years to come to narrowing down upholstery patterns and meaningful accents, the process can quickly become overwhelming — no matter how many design magazines you flip through or Pinterest boards you create. Even when you’re confident…
Interior designer Nancy Cavaliere relies on a clever, easy-to-follow “3-4-5 rule” for decorating. This simple formula — three patterns, four style influences, and five colors or textures — brings clarity to the chaos of design, helping to create a layered, personality-filled space. Think of it less as a rigid rule and more like a recipe that’s hard to mess up.
Without a framework like the 3-4-5 rule, a room can feel unintentionally random or, conversely, overly matchy-matchy. This approach helps you strike the perfect balance, resulting in a space that feels thoughtfully collected over time, rather than forced or overdesigned.
What Is the 3-4-5 Rule?
Cavaliere’s formula is straightforward. To her, a well-designed space should feature three patterns, four style influences, and five colors or textures. Together, these elements serve as the foundation for a creative, confidence-boosting design.

Three patterns: Whether you opt for striped drapery, floral wallpaper, or a zebra-print rug, patterns add movement and energy. The secret is varying the scale and mood of each pattern (so, avoid pairing two small-scale florals), while connecting them through a shared color palette or overall vibe.
Four style influences: This layer grounds a space with character and a sense of history. Instead of committing to a single style, mix pieces that nod to different design eras. For example, pair a contemporary minimalist sofa with a mid-century modern accent chair and a traditional floor lamp. The result feels curated and personal — not like a “room-in-a-box” bought in a single afternoon.
Five colors or texture: A variety of tones and textures ensures a space feels layered, not flat. You can incorporate these through paint, upholstery, and finishes. Don’t underestimate the power of texture, either; bouclé, velvet, wood, stone, and metal all count toward your total. Textures add depth and a tactile quality that makes an ordinary room feel like a place where you can kick up your feet and stay awhile.
