To select the right wallpaper for your surface, consider factors such as the room's decor style, lighting, and size. Choose a wallpaper pattern that complements or contrasts with your decor style and color scheme. Consider the lighting in the room as well, as it can affect the look of the wallpaper. For smaller rooms, opt for lighter colored and smaller patterns to create a more spacious feel. Conversely, for larger rooms, you can choose bolder patterns or larger prints. Additionally, consider the durability and maintenance requirements of the wallpaper before making a final decision.
