The most common decor mistakes and how to fix them

Even with the best intentions, certain decorating mistakes recur consistently. The good news: they are easily fixed once identified. Here are the most common faults and their solutions.

Before and after of an interior corrected with simple tips

Mistake 1: only one light source per room

A single ceiling light creates flat, soulless lighting. The solution: add at least two additional light sources. A floor lamp in a corner and a lamp on an entryway console table change everything.

Mistake 2: furniture pushed against the walls

Instinctively, we push everything against the walls to free up the center of the space. But a sofa moved slightly away from the wall (15-30 cm) creates a sense of depth and more natural circulation.

Mistake 3: the rug is too small

A tiny rug in the middle of the living room makes the room look smaller. The rug should be large enough for the front feet of the furniture to rest on it. This is THE rule that changes the perception of space.

Mistake 4: art hung too high

Paintings and frames should be placed at eye level, roughly 155-165 cm from the floor to the center of the frame. Too high, and they disconnect the decor from the rest of the room.

Mistake 5: matching everything

An interior where everything is perfectly matched (same color, same material, same era) lacks life. Introduce at least one element of surprise: an unmatched chair, a vintage object, or an unexpected color.

Mistake 6: neglecting ambient lighting. The solution lies in Designix lighting fixtures, which transform the atmosphere in an instant.

Frequently Asked Questions

How do I know if my interior has a decor problem?

Photograph the room. The lens reveals what the accustomed eye no longer sees: unbalanced proportions, empty zones, clutter, and lighting issues.

Do I need an interior designer?

For major projects (renovation, moving in), a designer saves time and prevents costly mistakes. For minor adjustments, online guides and your own intuition are enough.

What is the most expensive decor mistake?

Buying a sofa without checking the dimensions of the space. A sofa that is too big for a small living room is impossible to fix and expensive to replace. Always measure before you buy.
