Avoiding common home design mistakes in your home
1. Choosing the smallest rugs
One of the most common home design mistakes is choosing an accent that doesn’t complement the room. A rug that is too small can make the furniture feel disconnected and the entire space look unfinished, even if everything else is done well.
Why this happens:
- Rugs are often chosen based on price rather than room size
- People underestimate how much grounding is required
- Showroom rugs look larger than when they are placed in a real room
Why it’s a problem:
- It makes rooms feel small and uneven
- It breaks the visual flow of the furniture
- It creates a “floating furniture” effect that feels uncomfortable
How is it fixed
The key is to choose a rug that adheres well to your furniture. In living rooms, aim for at least the front legs of sofas and chairs to rest on the rug. For dining rooms, choose a rug that is large enough for the chairs to sit on when you roll it out. And in bedrooms, make sure the rug extends beyond both sides of the bed to create a grounded, cohesive look.
Pro tip: When in doubt, size up—large rugs quickly make a space feel purposeful and pulled together.
2. Ignoring light as a design element
Lighting it’s one of the most overlooked aspects of home design, yet it can completely change the way a space looks and feels. Relying on one ceiling or mismatched bulbs can leave rooms feeling flat, harsh, or unattractive, even if the furniture and decor are beautiful.
Why this happens:
- Homeowners focus on furniture and decor but neglect lighting
- People mix bulbs and temperatures of different colors without realizing it
- One central location is thought to be sufficient for every job and situation
Why it’s a problem:
- Rooms feel uneven or harsh
- Colors may appear off depending on the time of day
- The overall space can feel uninviting or chaotic
How is it fixed
The solution is a combination of layer light and keeping temperatures constant. Start by setting the ambient, task, and lighting tone for each room. Use warm tones in bedrooms and cool, bright lights in kitchens and bathrooms. Following these steps will quickly make the room feel balanced, efficient, and welcoming.
Pro tip: Joyce Huston, founder and Lead Interior Designer at Decorillashares his insights on how lighting affects your space: “A common mistake is mixing light color temperatures without realizing it. LEDs give you endless options now, and ‘daylight’ sounds great on the box until it reads harsh and fluorescent in your real space.” Keep temperatures consistent in each area (warm bedrooms, warm kitchens and baths) so the home feels cohesive instead of chaotic.”
3. Using the wrong paint color for lighting
Even a good paint color can look completely different on your walls, depending on the lighting in the room. Color selection without considering natural and artificial light can turn a fresh, attractive color into something flat, harsh, or “dull.”
Why this happens:
- Paint looks different in the shop under bright, consistent lighting than it does at home
- Homeowners don’t check swatches in many parts of the room
- Changes in natural light throughout the day are ignored
Why it’s a problem:
- Colors can appear too dark, too cold, or too warm
- Contrasting lighting can make furniture, flooring, or decor clash
- Rooms can feel small, dim, or unwelcoming
How is it fixed
Always check paint swatches in the room you plan to paint, looking at them at different times of the day and under artificial lighting. If the color looks different in certain areas, adjust the color slightly or choose complementary undertones to create a cohesive look. Taking the time to see how light interacts with your paint can save you from expensive and frustrating work.
Pro tip: Test your paint samples on multiple walls and in all lighting conditions before committing—it’s easier to change a test patch than to repaint an entire room.
4. Forgetting about storage in the design process
It’s easy to focus on style and forget function, though storage it is an important part of any well-designed home. Without adequate storage, even the most beautiful rooms can feel cluttered and chaotic.
Why this happens:
- Homeowners underestimate how much storage they really need
- Design trends prioritize minimalism over practicality
- Existing storage options are not integrated into the overall design
Why it’s a problem:
- Clutter accumulates, making rooms feel small and disorganized
- Beautiful furniture and decorations can hide dirt
- Everyday life becomes less and less stressful
How is it fixed
Add storage to the building from scratch. Use built-in cabinets, floating shelves, multi-functional furniture, and hidden storage solutions like ottomans or benches. Make sure wardrobes, pantries, and other storage areas are easy to access and match the style of the room so functionality doesn’t feel like an afterthought. Thoughtful maintenance helps keep the home clean, organized, and presentable.
Pro tip: Choose furniture that does double duty—like a coffee table with drawers or a bed with storage underneath—to maximize space without sacrificing style.
5. Choosing furniture that is the wrong scale
Furniture that is too big or too small can throw off the balance of a room, making it feel crowded or empty. Even well-styled pieces won’t look right if their size doesn’t fit the space.
“One common home design mistake is not taking proper measurements to make sure the furniture is the right scale,” advises Yvonne Jacobs, founder and chief designer of Jacobs + Interiors. “I come to a house where a customer has just bought furniture, but the scale is off and things don’t fit.”
Why this happens:
- Homeowners don’t take proper measurements before buying
- Showroom displays can make furniture look smaller or larger than it actually is
- Popular pieces are often chosen for style over function
Why it’s a problem:
- Furniture that is too large can make rooms feel cramped and difficult to navigate
- Small furniture can make a space feel small and disconnected
- Low-quality furniture disrupts the overall flow and balance of the room
How is it fixed
Always measure your space before buying large pieces. Consider the size of the room, the traffic patterns, and how you plan to use each area. Use painter’s tape on the floor to define where the furniture will go so you can visualize the scale before you do. Taking the time to match furniture to your space ensures that the room feels balanced, comfortable, and cohesive.
Pro tip: Remember to leave at least 30–36 inches of walking space around seating areas—comfort and flow are as important as style.
6. Designing a look instead of a lifestyle
It’s easy to get caught up in trends or magazine-worthy aesthetics, but designing a home that looks good is no different building a home that fits your lifestyle. A beautiful but dysfunctional room can be frustrating to use.
Why this happens:
- Homeowners prioritize style over everyday functionality
- Trends and “Instagram-worthy” ideas can override practical needs
- Furniture and fixtures are chosen for appearance rather than luxury
Why it’s a problem:
- Rooms can be difficult to live in, especially for families or pets
- Performance requirements such as storage, traffic flow, and usability are at risk
- The aesthetic appeal fades if the space is not functional in everyday life
How is it fixed
Before you commit to any design choice, think about how you use each space and how it fits into yours kind of home. Consider traffic patterns, storage needs, family routines, and pets. Balance style with function—choose pieces and designs that look good but also make life easier. A home designed for a lifestyle feels effortless, comfortable, and inviting, not only is it beautiful.
Pro tip: Assess your layout and furniture placement with daily routines in mind—if something feels off, it’s best to fix it before it becomes permanent.
Avoiding common home design mistakes in your home
Common home design mistakes happen to everyone, but the good news is that they’re usually easy to fix with a little planning and effort. By paying attention to light, scale, and how each room is actually used, you can transform problematic areas into spaces that feel good and work well. With a few smart updates, your home can look more cohesive—and feel better to live in every day.
