Lund and Browder diagrams for estimation of total burned surface area (TBSA). The “rule of nines” (using multiples of 9) is frequently used to assess the proportion of TBSA affected in adults and to help guide immediate treatment decisions based on burn size. However, the rule of nines is inaccurate in children due to different head-to-body size ratios at different ages. Lund and Browder diagrams are therefore more suitable for assessing of the proportion of TBSA affected in both children and adults. The body areas are separated into different regions (including anterior and posterior) by dashed lines and the numbers are percentages of the TBSA. For instance, 19 in the diagram for children aged 1–4 years relates to the face, neck and head that make up 19% of theTBSA
