Details make difference
Essential details which make the difference
The alignement
The alignment - Lets suppose that we have two floors of the same wood (boards). One looks as it should and is enjoyable. The other has something wrong "but don't know what". Well, the first one was installed with two eyes for detail and the other... with none.
First thing to consider is the alignment. This is influenced by the source of natural light (window positioning), shape and length of the surface and joists. But the most important factor is the natural light. The explanation - the majority of present boards have bevelled edges and by joining two boards both bevelled edges will form a grove. If this grove will sit perpendicularly to the ray of natural light, a shadow will be projected inside thus making it more obvious. But if this grove will sit in the same direction with the ray of natural light will become more discreet as the light will flood it.
The size
The size - Generally boards are big, or if possible huge, and battens are small. It is easy to understand from the bellow drawings why the bigger boards are preferred to smaller ones.
A simple explanation is that when boards are chosen the aim is to reveal as much wood as possible so the amount of joints has to be proportionately low. Instead, when going for parquet the joints are a must as they will give the wonderful pattern.
So, for the majority of floors, when choosing boards, I recommend a proper width between 180-230mm (the length will be proportionate around 1800-2500mm). If the surface is generous then you may opt for something special 450mm X 4000mm (which I installed and they are amazing!!!)

The pattern
The pattern - It matters a lot as it will have an important effect on looks and strength.
As you may see bellow the joints marked with red are not aesthetic. The floor is also very week when a wrong pattern is chosen (in time gaps will develop)
