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.

How this is calculated

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 18.37
II Light eyes; light hair Burns easily, tans poorly 22.04
III Any eye or hair color (very common skin type) Tans after initial burn 29.39
IV Dark brown hair; medium to heavy pigmentation Burns minimally, tans easily 36.74
V Dark hair; rarely sun sensitive Rarely burns, tans darkly easily 58.79
VI N/A Never burns, always tans darkly 110.22

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).
