Burn Area Calculator (Lund-Browder chart)
This calculator estimates burn area for adults and children using the Lund-Browder chart. Select the age first, then click on each body part to select the burned area.
📋 Body Surface Area Ratio by Age
- All ages: Lund-Browder chart applied (age-specific body proportion differences reflected)
- Adults (15 years and older): Fluid calculation using Parkland Formula
- Children (0-14 years): Fluid calculation using Galveston Formula
Pediatric characteristics: The younger the age, the larger the head proportion and the smaller the leg proportion.

💧 Fluid Resuscitation Formula
Adults (Parkland Formula): Weight(kg) × %TBSA × 4ml = Total 24-hour fluid volume
Children (Galveston Formula): 5000ml/m² × BSA(m²) + 1500ml/m² × Burn area(m²) = Total 24-hour fluid volume
- First 8 hours: 50% of total fluid volume (Ringer’s Lactate)
- Next 16 hours: 50% of total fluid volume (Ringer’s Lactate)
- %TBSA: Includes only 2nd degree or higher burns (excludes 1st degree burns)
- BSA: Uses Mosteller formula (√[(height×weight)/3600])
Note: Children use the Galveston Formula due to their higher weight-to-body surface area ratio. Actual treatment should be determined by medical professionals.
⚠️ Warning: The Lund-Browder chart is applied to all ages. For children, body proportions vary significantly by age, so accurate age selection is important. Actual treatment should be determined by medical professionals.
