You can have the nicest sofa, perfect wall colour, and carefully chosen furniture… but if your window dressings are off, the whole room can fall flat.

It sounds dramatic, but it’s true! Interior designers spot window-dressing mistakes immediately because windows are such a key focal point in any space.

The good news? Most of these mistakes are easy to fix once you know what to look out for.

Curtains That Are the Wrong Length

This is probably the most obvious one, and the one designers notice first.

Curtains that sit awkwardly above the floor can make a room feel unfinished and slightly off. On the flip side, curtains that pool too heavily can look messy if it’s not intentional.

Ideally, curtains should just skim the floor or lightly touch it. That clean line instantly makes a space feel more polished.

This is where made-to-measure curtains make a big difference, as they’re tailored to the exact height your room needs.

Not Enough Width or Fullness

Flat, stretched curtains are another giveaway. If your curtains barely cover the window when closed, they won’t create those soft folds that give a room that cosy, high-end feel.

Designers typically recommend at least double the width of the window for proper fullness. It’s one of those details people skip, but it massively impacts how the finished result looks.

Hanging Curtains Too Low

A lot of people install curtain poles just above the window frame. It feels logical, but it actually makes ceilings look lower, and windows feel smaller.

Interior designers almost always hang curtains higher than expected, sometimes much closer to the ceiling. This draws the eye upward and makes the whole room feel taller.

Pairing this with well-fitted made-to-measure blinds or curtains creates a much more balanced, intentional look.

Choosing the Wrong Type of Blind

Blinds are practical, but choosing the wrong style for the room can throw everything off.

For example, bulky blinds in a small room can feel heavy, while flimsy options in a large space can look underwhelming.

The key is matching the blind style to both the room and the window size. Made-to-measure blinds are particularly useful here, as they’re designed to suit your exact space rather than being forced to fit.

Ignoring Light and Function

It’s easy to get caught up in how something looks and forget how it works.

A room that gets a lot of sunlight might need light-filtering or blackout options, while a living space might benefit from something more flexible.

Designers always consider both style and function. The best window dressings look great and work effortlessly throughout the day.

Choosing made-to-measure blinds or curtains allows you to tailor both the look and performance to your needs.

Forgetting to Tie Everything Together

Window dressings shouldn’t feel like an afterthought. If your curtains or blinds don’t relate to anything else in the room, whether that’s colour, texture or style, they can feel disconnected.

Simple touches like coordinating with cushions, throws, or other soft furnishings help everything feel cohesive. It’s not about matching everything perfectly, but about creating a sense of flow throughout the space.

Small Changes, Big Impact

The difference between a room that looks “fine” and one that feels properly finished often comes down to details like these.
