When it comes to choosing new blinds, it is easy to think that you can’t go too far wrong. As long as they protect against sunlight and fit into your overall scheme, there seems like there is not too much to consider – but interior design experts have warned that the process is more complex than it may initially seem. 

Your window blinds ideas are, in fact, amongst the most impactful ways to change the light and color of your room – so it is vital to get them right.

Whether you’re looking for living room, bedroom, or bathroom blind ideas, the process and the mistakes remain the same. Here’s what you need to know before making any investment. 

1. Not considering the function of your blinds 

'One of the most common mistakes people make when choosing window blinds is not considering the function they'll serve,' says Dan Smith from Express Essex Blinds. While this may seem like an obvious question, Dan explains that each blind has a particular form – so if you're looking to block out light, you may need to sacrifice another function. 

'Are you looking for something to block out light completely? Do you need something that's easy to clean? Think about how you'll be using the blinds before making a purchase. This will help you narrow down your options and choose the right product for your needs,' Dan adds.

2. Mis-measuring your windows  

Measuring windows for curtains and blinds is amongst the most mundane of jobs, but despite its simplicity nature, it is a vital step in the buying process to get right. 'Be sure to measure both the width and height of the window, so you can order blinds that fit perfectly,' Dan says. 

Many experts recommend going at least 2in wider than the opening on either side to give yourself some room for the brackets when you try the blinds at home.  

3. Not considering how the blind will look in your room's light  

If you're browsing blinds online or in-store, the color may likely appear different than it will when held up against your window. So, while some window treatment ideas may look good in certain lights, they may seem entirely different in your home. 

'Make sure you choose a style that compliments the overall look of your home,' Dan explains. And, colors aside, he also suggests reading your product descriptions carefully to know the materials you are getting and how they may translate in your space.

4. Not planning for new windows

The possibility of new windows may seem relative when choosing your blinds now, but Justin Reif, an expert from WindowWorks Co in North Carolina suggests it is one of the biggest mistakes your can make. 

'When purchasing new blinds, homeowners should be aware that, if they plan to replace their windows in the future, their new blinds may not fit into their new window frames,' Justin says. 

While it may seem like your future window will be the same size,  Justin explains that, in some cases, your new glass could be different, especially if you're choosing insert replacements that will be smaller than the existing window. 

Alternatively, your 'window profile may be different and not allow the blinds to be installed the same way,' he adds.

5. Forgetting about future function 

Similarly, Justin urges you to consider the ever-changing of your blinds that may change over the seasons. 'Homeowners should also consider that their blinds may still be usable on the new window but may look or operate differently,' he says.

For example, if you are replacing a picture window or single hung window with a double-hung window, you will be left with a rail across the middle of your window. Therefore, if your blinds were installed inside the window frame, they will have a bump every time they fall over the rail.

Whether you're considering new window seat ideas or simply looking to repaint your space, your choice of curtains now will be impacted by future design decisions. It is always best to make them carefully for a window that will look seamless and stylish for years to come. 

How do you get rid of light gaps?

To get rid of light gaps between the edge of a window blind and the frame, you will need to hang drapes or drapery panels either side of the blind. If you are bothered by light gaps, perhaps they are in a bedroom, you will need to considering lining the drapery with black-out fabric.
