Editing Snowboard (section)

=== Snowboard designs differ primarily in ===
*Length – Boards for children are as short as {{convert|80|cm}}; boards for racers, or "alpine" riders, are as long as {{convert|215|cm}}. Most people ride boards in the {{convert|140|–|165|cm}} range. Board length used to be judged by the height of your chin. If a board held next to the frontside of your body came to your chin then it was an acceptable length. Due to the development of new technologies and board shapes, people can now ride a wider range of board sizes.<ref>{{Cite web|title = Snowboard Size & Buying Guides Houston|url = http://www.m2sports.com/things-to-look-for-when-buying-a-snowboard|website = www.m2sports.com|access-date = 2015-10-19}}</ref><ref>{{Cite web|url=https://www.evo.com/how-to-choose-a-snowboard-size-chart-and-buying-guide.aspx#shape|title=Snowboard Sizing & Buyer's Guide {{!}} evo|website=www.evo.com|access-date=2016-05-05}}</ref> Rather, the length of a snowboard corresponds mainly to the style, weight, and preference of the rider. A good rule of thumb is to stay within the recommended manufacturer weight range. The longer the board, the more stable it is at high speed, but it is also a bit tougher to maneuver. Another factor riders consider when selecting a snowboard is the type of riding it will be used for, freestyle boards being shorter than all-mountain boards.
*Width – The width is typically measured at the waist of the board, since the nose and tail width varies with the sidecut and taper. Freestyle boards are up to {{convert|28|cm}} wide, to assist with balance. Alpine boards are typically {{convert|18|–|21|cm}} wide, although they can be as narrow as {{convert|15|cm}}. Most folks ride boards in the {{convert|24|–|25|cm}} range. Riders with larger feet (US size 10 and larger) may have problems with narrower boards, as the rider's toes and/or heels may extend over the edge of the board, and interfere with the board's ability to make turns once it is set on edge, or 'get hung up on the snow.' This is called toe/heel-drag, and can be cured by either choosing a wider board ({{convert|26|cm}} or more), adjusting the stance angle, or a combination of the two.
*Sidecut – The edges of the board are symmetrically curved concavely, so that the width at the tip and tail is greater than the center. This curve aids turning and affects the board's handling. The curve has a radius that might be a short as {{convert|5|m}} on a child's board or as large as {{convert|17|m}} on a racer's board. Most boards use a sidecut radius between {{convert|8|-|9|m}}. Shorter sidecut radii (tighter turns) are generally used for halfpipe riding while longer sidecut radii (wider turns) are used for freeride-alpine-racing riding. One new development in sidecuts was the introduction of Magne-Traction by [[Mervin Manufacturing|Mervin]], which manufactures: Lib Tech, GNU, and Roxy snowboards. Magne-Traction incorporates seven bumps on each side of the board which LibTech speculates will improve edge holding.<ref>{{cite web|url=https://www.snowboarder.com/transworld-snowboarding-archive/snowboarding-photos/2006-board-test/ |title= 2006 Board Test |publisher=snowboarder.com|date=2005-10-13|access-date=2019-11-30}}</ref>
*Flex – The flexibility of a snowboard affects its handling and typically varies with the rider's weight. Usually a harder flex makes turning harder while a softer flex makes the board less stable at high speed. There is no standard way to quantify snowboard stiffness, but novices and boarders who mostly do rails tend to prefer softer flex, racers stiffer flex, and everyone else something in between. Park riders that enjoy jumps the most tend to ride stiffer twin boards.
* Tail and nose width – Many freestyle boards have equal nose/tail specs for equal performance either direction. Freeride and alpine boards, however, have a directional shape with a wider and longer nose. Boards designed for powder conditions exaggerate the differences even more for more flotation on the powder.
* Camber – The curvature of the base of the snowboard affects handling and carving. Typical modern snowboards have an upward curvature of a few degrees along the effective edges. Experimentation has led to boards with rocker, or upward curvature, which makes for a more buttery board and can improve float in deep powder. As time has progressed, modern boards now offer variations of camber-rocker boards that fulfill the different needs and preferences of its rider.
