The herringbone pattern can visually affect the perceived size of a room, but whether it makes a room look bigger or smaller can depend on a few factors.
In general, herringbone flooring can create an illusion of more space in a room due to the diagonal lines and angles that draw the eye outward. This can make a room feel more open and expansive, especially if the herringbone pattern is installed perpendicular to the longest wall in the room. Additionally, using lighter-colored herringbone flooring can also make a room appear larger, as light colors tend to reflect more light and make spaces feel brighter and more open.
However, the size of the room and the size of the herringbone pattern can also affect the overall perception of the space. In smaller rooms, using a larger herringbone pattern can make the space feel cramped and busy, while a smaller herringbone pattern can create a more cohesive and visually pleasing effect. Conversely, in larger rooms, a smaller herringbone pattern can feel too busy and cluttered, while a larger pattern can create a more grand and dramatic effect.
Ultimately, the perceived size of a room with herringbone flooring can depend on a combination of factors, including the size and shape of the room, the size of the herringbone pattern, and the colors and finishes used in the flooring.
