Without formal design education, it’s easy to make mistakes when decorating your home. Unfortunately, these mistakes often waste time and money and can leave homeowners feeling frustrated and disappointed. Below are the top 10 interior design mistakes I see most often—and how to avoid them.
1. Buying a Rug That’s Too Small
A rug that’s too small diminishes the size of a room and makes it feel incomplete. A properly sized rug, on the other hand, enlarges a room and creates a welcoming atmosphere. Ideally, a rug should leave about two feet of exposed flooring around the perimeter of the room. All furniture should be placed on the rug, though the back legs of the sofa or small end tables can be exceptions.
2. Thinking Furniture Alone Makes a Room
Simply purchasing a sofa or a bedroom set doesn’t complete a room. A finished, photograph-worthy space requires layers: rugs, window treatments, lighting, throw pillows, art, plants, and accessories. These elements work together to reflect the homeowner’s personal aesthetic and create a cohesive design.
3. Incohesive Style
Every room should tell a story—your story. Take time to research styles and develop a clear point of view. Consider where you fall on various spectrums: formal vs. informal, traditional vs. modern, or bright vs. subdued. While Instagram and Pinterest can offer inspiration, they often focus on trends that may quickly date your home. Timeless design comes from understanding what authentically represents you.
4. Using Too Many Family Photos
While family photos are meaningful, scattering too many throughout your home can overwhelm the design. Instead, choose your favorites and display them thoughtfully. For example, enlarge key photos in black and white with thick mat borders or have them printed on canvas. Consider creating a dedicated memory wall where photos are grouped together for a more intentional and impactful display.
5. Buying Cheap Products
Bargain furniture and decor may be tempting, but they often compromise on quality and lack distinction. Investing in your home’s interior should match the level of care and quality given to the exterior. Take time to explore stores and inspiration sources that feature timeless, high-quality pieces.
6. Neglecting Art
Art brings color, pattern, and personality into a room. Whether it’s a bold statement piece or a subtle complement, art can enhance a space or serve as a focal point. Don’t overlook this critical design element.
7. Playing It Too Safe
Neutral tones and classic pieces are a smart foundation, but too much caution can lead to dull, uninspired spaces. Balance neutrals with texture, color, or patterns to add interest. For example, pair floral wallpaper with solid drapes or a bold rug with a neutral sofa.
8. Skipping the Floor Plan
A lack of planning often results in wrong-sized furniture, forgotten items, and a lack of symmetry or balance. Avoid these pitfalls by creating a detailed floor plan. Use graph paper, invest in a design kit, or hire a professional to ensure your space is functional and cohesive.
9. Settling for Ready-Made Window Treatments
High-quality, custom window treatments elevate both the function and appearance of a room. Budget for professionally installed treatments that complement your overall design.
10. Not Hiring a Designer
Hiring an interior designer might feel like an added expense, but it can save you time and money in the long run. A designer ensures the process is enjoyable and, most importantly, that you’re happy with the results.
