Accurate wound measurement is essential to assess healing progress and guide treatment.
Length and Width: Measure the longest length (head-to-toe direction) and the widest width (perpendicular to the length) using a metric ruler or measuring tape.
Depth: Gently insert a moistened cotton-tipped applicator into the deepest part of the wound until resistance is felt, then measure that distance.
Tunneling and Undermining: Note any tunneling or undermining using the “clock method” (e.g., from 12 o’clock position) and record the depth and direction.
Consistency: Take all measurements in centimeters, under consistent lighting and patient positioning, to ensure comparability.
Surface Area: For regular-shaped wounds, the area can be estimated by multiplying length × width, though this may overestimate irregular wounds.
