Have you ever wondered what a professional interior designer would think about your design choices? In particular, there is one room that is very important: the living room.

Interior designers reveal the top mistakes that many people make when decorating their living room. Learn what the mistakes are and how to fix them to make your living room look amazing, with the expert advice of interior designers. 1. Rug size matters While you should pick a rug that matches the decor in your living room, you should also choose a rug size that fits well. If you choose a rug that is too big, it can make the room appear smaller. This would be bad if the room is already pretty small. If the rug is too small, it may look like there is wasted space in the room or the furniture might get too close together. Use painters tape to check the size of a rug before you purchase.

Have multiple light sources Sometimes you may want a bright living room, while other times you may just want dim lighting. Let yourself have that option. Have an overhead light on dimmer if you can and several lamps around the room. 6. Furniture size matters too Just like rug size, furniture size matters as well. If the furniture you choose is too big or too small, it can make the room feel uneven or too small. According to Insider, interior designers recommend, "For larger living rooms, she recommended leaving 30 to 36 inches between furniture pieces. Smaller spaces, like apartments, can get away with 18 to 24 inches between pieces." 7. Have plenty of tables You will want to have a table or other surface to set down drinks or other items from wherever you'd want to sit. Some couches come with small tables and cup holders now, but side tables and coffee tables can be equally as convenient.
