Snowboards are boards where the users places both feet, usually secured, to the same board. The board itself is wider than most skis, with the ability to glide on snow. Snowboards widths are between 6 and 12 inches or 15 to 30 centimeters. Snowboards are differentiated from monoskis by the stance of the user. In monoskiing, the user stands with feet inline with direction of travel (facing tip of monoski/downhill) (parallel to long axis of board), whereas in snowboarding, users stand with feet transverse (more or less) to the longitude of the board. Users of such equipment may be referred to as snowboarders. Commercial snowboards generally require extra equipment such as bindings and special boots which help secure both feet of a snowboarder, who generally ride in an upright position. These types of boards are commonly used by people at ski hills, mountains, backcountry, or resorts for leisure, entertainment, and competitive purposes in the activity called snowboarding.

Diagram of a Snowboard and its various elements that affect sizing
The bottom or 'base' of the snowboard is generally made of UHMW and is surrounded by a thin strip of steel, known as the 'edge'. Artwork was primarily printed on PBT using a sublimation process in the 1990s, but poor color retention and fade after moderate use moved high-end producers to longer-lasting materials.
Snowboards come in several different styles, depending on the type of riding intended:
Freestyle: Generally shorter with moderate to soft flex. Freestyle snowboards have a mirror shovel at each end of the board. Freestyle snowboards usually have low-backed bindings. Incorporates a deep sidecut for quick/tight turning. Used in the pipe and in the park on various jumps and terrain features including boxes, rails, and urban features.
Park/Jib (rails): Flexible and short to medium length, twin-tip shape with a twin flex and an outward stance to allow easy switch riding, and easy spinning, a wider stance, with the edges filed dull is used for skateboard-park like snowboard parks.
Freeride: Longer than freestyle and park boards. Moderate to stiff in flex and typically directional (versus twin-tip). Used from all-mountain to off-piste and backcountry riding, to 'extreme' big-mountain descents - in various types of snow from groomed hard-packed snow to soft powdery snow.
Powder: Highly directional boards that typically have a rockered nose and tapered shape (wider tip than tail).
All-Mountain: Most common. A mix between freeride and freestyle boards. The 'jack of all trades, master of none.' Commonly directional or directional twin in shape (twin-tip and centered stance but with more flex on the front)
Racing/Alpine: Long, narrow, rigid, and directional shape. Used for slalom and giant slalom races, these boards are designed to excel on groomed slopes. Most often ridden with a "hard" plastic snowboard boot (similar to a ski boot), but also ridden recreationally with soft boots, particularly by riders in Europe.
Splitboard: A snowboard which splits in half lengthwise, and allows the bindings to be quickly connected to hinges aligning them longitudinally on the board, allowing the halves of the boards to function as cross country skis. Used with removable skins on the base of the board, which easily slide forward on snow but not backwards, they allow a snowboard to easily travel into the backcountry. Once the rider is ready to descend, the board halves can simply be joined back together.
Snowboards are generally constructed of a hardwood core which is sandwiched between multiple layers of fibreglass. Some snowboards incorporate the use of more exotic materials such as carbon fiber, Kevlar, aluminium (as a honeycomb core structure), and have incorporated piezo dampers. The front (or "nose") of the board is upturned to help the board glide over uneven snow. The back (or "tail") of the board is also upturned to enable backwards (or "switch") riding. The base (the side of the board which contacts the ground) is made of Polyethylene plastic. The two major types of base construction are extruded and sintered. An extruded base is a basic, low-maintenance design which basically consists of the plastic base material melted into its form. A sintered base uses the same material as an extruded base, but first grinds the material into a powder, then, using heat and pressure, molds the material into its desired form. A sintered base is generally softer than its extruded counterpart, but has a porous structure which enables it to absorb wax. This wax absorption (along with a properly done 'hot wax'), greatly reduces surface friction between the base and the snow, allowing the snowboard to travel on a thin layer of water. Snowboards with sintered bases are much faster, but require semi-regular maintenance and are easier to damage. The bottom edges of the snowboard are fitted with a thin strip of steel, just a couple of millimeters wide. This steel edge allows the board to grab or 'dig into' hard snow and ice (like the blade of an ice skate), and also protects the boards internal structure. The top of the board is typically a layer of acrylic with some form of graphic designed to attract attention, showcase artwork, or serve the purpose similar to that of any other form of printed media. Flite Snowboards, an early designer, pressed the first closed-molded boards from a garage in Newport, Rhode Island, in the mid-1980s.[citation needed] Snowboard topsheet graphics can be a highly personal statement and many riders spend many hours customizing the look of their boards. The top of some boards may even include thin inlays with other materials, and some are made entirely of epoxy-impregnated wood. The base of the board may also feature graphics, often designed in a manner to make the board's manufacturer recognizable in photos.
Snowboard designs differ primarily in:
Length – Boards for children are as short as 90 centimetres (35 in); boards for racers, or "alpine" riders, are as long as 215 centimetres (85 in). Most people ride boards in the 140–165 centimetres (55–65 in) 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. 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 28 centimetres (11 in) wide, to assist with balance. Alpine boards are typically 18–21 centimetres (7.1–8.3 in) wide, although they can be as narrow as 15 centimetres (5.9 in). Most folks ride boards in the 24–25 centimetres (9.4–9.8 in) 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 (26 centimetres (10 in) 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 5 metres (16 ft) on a child's board or as large as 17 metres (56 ft) on a racer's board. Most boards use a sidecut radius between 8–9 metres (26–30 ft). 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, 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.
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.
