offwidth

Offwidth refers to a climbing technique and a specific type of climbing crack that presents a challenge for traditional jamming methods. It generally describes cracks that are too wide for hand jams but too narrow for body-length stemming or chimneying. The climber often finds themselves in a position where their body is inserted into the crack, requiring a combination of stemming, bracing, and sometimes hip-scumming or body-bridging maneuvers to progress.

The difficulty of offwidth climbing stems from the lack of secure handholds and the need for specialized techniques. Climbers must find ways to generate friction and stability using their legs, hips, and even their feet against the crack walls. Common techniques include fist jams, foot jams with turned-in toes, and sometimes "chicken wing" jams where an elbow is wedged into the crack. The physical exertion and awkward body positions make it a strenuous and often uncomfortable style of climbing.

Offwidth climbing is often encountered in granite and sandstone environments where large, flaring cracks are more prevalent. It is considered by many to be a mental and physical test, requiring a high degree of technique, strength, and problem-solving ability. Mastering offwidth climbing can be a significant accomplishment for a rock climber.
