Comparison of wound photography and digital planimetry methods on wound size measurement

	Method	Advantages	Disadvantages
Wound photography	Using digital photography to measure and analyze wound size and dimensions.	Nonwound contact measurement. Universally applicable. With short-term healing predictability.	Lacks long-term predictability of healing potential.
Digital planimetry	Tracing the wound margin with transparent films, and then manually counting the number of grid boxes filled or partially filled by the wounds or the wound area. The tracing can also be imported into computer to calculate wound area using a software.	High accuracy on wound size measurement.	Requires wound contact. Only allows two-dimensional wound measurement.
