One of the first things you can do to make a small room seem wider is to add some big pieces of decor. While this isn't always feasible, it's one of the best ways to add space without feeling cluttered. This trick involves placing a large piece of furniture or artwork in the center of the room. This will make the room appear wider and will distract the eye from the narrower portion of the space.
The next tip on how to make a narrow room look wider is to compartmentalize the room. If the room is small, try to divide it into smaller sections, such as a dining area and a living area. You can do this by using different types of furniture or home decor to create distinct areas. These areas will help you organize your space and make it more comfortable. By keeping the main function of a room separate, you'll be able to use more space in the room.
Adding visual interest to your room will give it more width. Using different colors in different rooms can help to create the illusion of a wider space. You can also use the same color scheme in different parts of the room. For instance, you could place furniture on one side of the room, and the other half should be for other purposes. If you have a small living room, try adding some more color, or a darker color on the other side.
