The dimensions of the deck in length and width (according to the largest dimensions).
Both small and large decks have their advantages and disadvantages. So, a short and narrow deck contributes to manoeuvrability, but puts forward additional requirements for the rider's skill — it can be difficult to cope with a small "nimble" skate, especially at high speed.
A long and wide board, on the contrary, is more stable, but it is difficult to make sharp manoeuvres on such a skateboard. In addition, the optimal length for each type of skate (see above) also depends on the age category of the skater: for example, classic skateboards in the adult version have boards no shorter than 600 mm, and anything less refers
to children's models. The width, in turn, can be determined by the size of the foot: a person with a large size (from 44) may simply be uncomfortable on a narrow deck.
Detailed recommendations on the optimal dimensions for each type of skate and planned riding features can be found in special sources.
