I semi-recently moved, and my new bedroom was, rather disappointingly, less than half the size of my previous one. I had to make things work, so I rolled up my sleeves and got to decorating. Below are some tips I think helped me to create a rather cosy space, while being on a budget.
Plan around the space you have
The first and most obvious is to plan according to the space you have. Get some inspiration from similar-sized bedrooms on Pinterest and Instagram, or wherever, and create an idea in your mind of what you want the overall space to look like- including mood, colour scheme and furniture. Then, get to work measuring different areas to make sure the furniture you buy fits in the space you have.
Use lighter colours on your walls

Darker colours tend to make spaces look smaller, so if you want to make your space seem slightly more spacious, stick with lighter colours, especially for the walls and curtains.
Organise your space
A well-organised room will help you take full advantage of the space you have. So, have a plan in mind (or on paper) for where clothes, shoes, jewellery, etc. will go and try to stick to it. This will likely have a significant positive improvement on your bedroom. Consider under-bed storage and tall (rather than wide) cabinets or bookcases.
Make the bed the star of the show
Maybe you don’t have the space to throw in a reading corner, or to have a TV unit. But you almost definitely have got a bed in the bed room. SO why not make it the star? Invest in nice plush pillows, maybe a couple of cushions, perhaps a nice throw. You can go bold with the colour/pattern, or stick to the chic, clean white bedding aesthetic. Either way, investing in nice bedding and keeping your bed tidy can instantly give your room a face-lift.
Bring the outside in
And then of course, grab some plants if you are that way inclined. It brings colour and a sense of vibrancy to any room (so long as they remain alive). Use plant macrame hangers or just line them on the window sill. Alternatively, some pretty flowers in a vase on the bedside table could also do the trick.
Install some shelves
Maybe not excessively, but they can really help to create more surface area for things like books, photos, or even more plants. I’ve been liking the look of above the bed shelving, but I’ve seen some very practical above curtain shelving, that creates a decent amount of storage, without making the space seem smaller
