Safe Exposure Time Calculation (Time to Burn Chart)

The most commonly used scheme to classify a person's skin type by their response to sun exposure — the degree of burning and tanning — was developed by Thomas B. Fitzpatrick, MD, PhD. As a matter of fact, even the skin colours of Emoji characters are based on the Fitzpatrick scale.

Skin Type Color Typical Features Tanning Ability Time to Burn (minutes)
I Red or blond hair; light-colored eyes; freckles likely Always burns, does not tan 18.22
II Light eyes; light hair Burns easily, tans poorly 21.86
III Any eye or hair color (very common skin type) Tans after initial burn 29.15
IV Dark brown hair; medium to heavy pigmentation Burns minimally, tans easily 36.44
V Dark hair; rarely sun sensitive Rarely burns, tans darkly easily 58.3
VI N/A Never burns, always tans darkly 109.31

Ultraviolet Radiation Reflection from Surfaces

Highly reflective surfaces — including concrete, snow, glass, water and polished metals — can increase the surrounding levels of solar UV (see source).
