5 design mistakes you're probably making right now

While there are no hard and fast rules in interior design, and your home should primarily reflect your personal taste, there are still some basic principles that can instantly make a room appear more harmonious, spacious, and sophisticated. Many common mistakes can be easily corrected. Here are five typical design errors—and how to avoid them.

1. The carpet is too small.

One of the most common mistakes is choosing a rug that is too small. If the rug is too small, the room appears restless, fragmented, and loses its visual balance.

The solution: In the living room, at least the front legs of all furniture should be on the carpet, ideally all legs. In the bedroom, there should be a carpeted area approximately 60 cm wide around the bed. In the dining room, the carpet should be large enough so that all chair legs rest on it, even when extended.

2. The curtains are incorrectly mounted.

Curtains hung too low or too narrow make windows appear smaller and take away valuable height and light from the room.

The solution: Hang the curtain rod as high as possible – ideally just below the ceiling – and significantly wider than the window. This makes the room appear taller, brighter, and more spacious.

3. Too much “matching”

If furniture, colors and fabrics are too closely coordinated, the room quickly appears boring and flat.

The solution: Focus on contrasts, textures, and one or two additional accent colors. Even in monochromatic rooms, different materials, patterns, and shades add depth and visual interest.

4. Art and mirrors are hung too high or too low

Even perfectly decorated rooms look "off" if wall decoration is positioned incorrectly.

The solution: Artwork and mirrors should be hung at approximately eye level – ideally with the center of the picture at a height of about 145 cm (or 56 inches). For gallery walls, the overall composition should be based on this line.

5. Lines of sight are ignored

A common mistake is to design each room separately without considering how the rooms interact. This can quickly make a house appear chaotic.

The solution: Pay attention to colors and materials that are repeated in adjacent rooms. Especially in open floor plans, repeated elements create a calm, harmonious overall impression.

Conclusion

Small adjustments can make a big difference. By properly proportioning rugs, correctly hanging curtains, strategically using colors and textures, strategically placing wall decorations, and keeping sight lines in mind, your home will instantly feel more harmonious, sophisticated, and inviting. The goal is a space that is functional, aesthetically pleasing, and truly reflects you.
