9 biggest mistakes in interior design and how to avoid them
Everyone wants a home that feels harmonious, cozy, and stylish. However, many people make fundamental mistakes that can disrupt the overall impression of the space. Take a look at the 9 most common missteps in interior design and find out how to fix them.

1. Too Much Furniture
Overcrowded rooms full of furniture feel cumbersome and cramped. Every piece of furniture should have its purpose and place. The room should have enough free space to feel open and harmonious. Consider removing excess pieces and focus on quality, multifunctional furniture that serves multiple purposes at once.
2. Incorrect Rug Size
A rug that is too small can visually divide the space and ruin the overall impression. A properly chosen rug should cover the entire seating area – the front legs of sofas and chairs should be on the rug. If in doubt, always opt for a larger rug that unifies the entire space.
3. Artwork and Decorations in the Wrong Place
Placing artwork too high or randomly arranging decorations can be distracting. Paintings should be hung at eye level, which is approximately 150 cm from the floor to the center of the painting. Decorations should match the overall style of the room, and their quantity should be moderate to prevent the space from feeling cluttered.
4. Lack of Textile Elements
Textiles, such as curtains, rugs, pillows, or throws, add coziness and warmth to a space. Without them, a room can feel impersonal. Choose quality textiles in colors that match the overall palette of the room, and don't forget about layering – different textures and materials will enliven the space.
5. Poor Color Combination
The right color scheme brings visual cohesion and aesthetic harmony to the interior. Use the 60-30-10 rule: 60% main color - for example, walls, 30% complementary color - for example, furniture, and 10% accent color - for example, textiles. This method ensures the color balance of the space.
6. Insufficient Lighting
One central light is not enough. A room should have layered lighting – ceiling lights, floor lamps, table lamps, or LED strips. Diverse light sources not only improve the functionality of the space but also create a pleasant atmosphere.
7. Inappropriate Curtains
Curtains that are too short or narrow can detract from the elegance of the interior. Always choose curtains that reach the floor and are wide enough to cover the entire window. If you place them as high above the window as possible, the room will appear taller.
8. Neglected Details
Details such as handles, knobs, sockets, or moldings can significantly affect the overall look of the interior. Invest in quality materials and elegant design.
9. Overcrowded Shelves
Overstuffed shelves look chaotic. Opt for a few larger decorations instead of many small ones. Groups of three items of varying heights always look nice and harmonious. You also can't go wrong by leaving some shelves empty to allow the space to breathe.
These 9 interior design mistakes are made by almost everyone, but with a little knowledge, they are easy to avoid. Proper planning, attention to detail, and balance are key to a home that feels cozy yet stylish.
