2) In terms of size, it is mainly the width of the board. Beginners should have no requirements in this respect. If you have to choose, I suggest that you use a relatively wide board because it is easier to control.
3) There is also the concavity of the board surface. Board friends are used to calling it "Foot Nest". At present, the professional boards are concave, that is, there is a downward arc between the two bridges when viewed from the side. The footwell is deep and shallow, so beginners are advised to choose shallow footwell board, which will be more stable when stepping on it. Easy to control.
In addition, there is the problem of laminates. It is even more irrelevant for beginners. Now most of the boards are 7-layer. Some medium maple boards are made of 9 layers to ensure strength. It will be heavier. You can see from the side of the board that the color of the third and fifth layers of the board will be heavier, because the boards of these two layers are laid horizontally. Beginners mainly learn to control the board and some basic movements, so there is no need to care too much about the number of boards and the weight of the board.
Of course, if you have sufficient funds when buying, it is recommended to choose a board with high strength, good toughness and light weight.
