Yes, it should tell you in the installation instructions.

Planks should run lengthwise against the longest wall, and if possible,[4 parallel to incoming sunlight.

This is out of the Shaw laminate floor installation instructions.

Thank you. I felt it should be vertical. The installer wanted horizontal. It will be from the entry through dining and living area. That will incorporate 13 x 30. Thought it might look too bowling allyish, but felt horizontal would look weird.
