In which direction should I install the floor?

Basically, you can install the floor in any direction (width or length) according to your own taste and personal preference. The best effect is obtained by installing the planks/tiles in the length, in the same direction as the main light sourche in the room and/or in line with the most frequently used door. To broaden your room, you better choose to install the planks/tiles parallel to the widest wall in the room. if the room has multiple doors and windows, you better choose the easiest method of installation.
