Scaling Blocks

Question in regard to the office project.

When scaling a reception desk (and desks in general), do i scale it from left to right or up and down (which is tech the width of a desk)?
When doing scale reference with a dimension, would I scale reference it from left to right or up n down?

Does it matter?

You would scale it based on the dimension you have. If the width is 60 you would scale the width of the depth to 60.
It will make a difference if you scale in the wrong direction. Unless its the same measurement on both sides.
