Answer 10 Questions to Estimate Your Skin Type
Fitzpatrick Skin Type Formula
Where:
- \(G_1 \ldots G_5\) — scores (0–4 each) for the five genetic questions: eye color, natural hair color, unexposed skin color, freckling and ancestry
- \(R_1 \ldots R_5\) — scores (0–4 each) for the five sun-reaction questions: first-exposure burning, tanning ability, tan depth, facial sensitivity and time to burn
- \(G\) — genetic disposition score (0–20)
- \(R\) — sun reactivity score (0–20)
- \(S\) — total questionnaire score (0–40)
Each answer is scored from 0 (lightest coloring, most sun-sensitive) to 4 (darkest coloring, most sun-resistant). The total \(S\) is then mapped to a skin type using the standard Fitzpatrick bands.

Fitzpatrick Skin Type – Calculation Example
Example: a person with blue-grey eyes, dark blonde hair, fair pinkish beige unexposed skin, several freckles and Northern/Central European ancestry (genetic answers 1, 2, 1, 2, 1), whose skin burns painfully and peels on first exposure, hardly tans, only reaches a light tan, often turns red on the face, and starts burning after 30–60 minutes without protection (reaction answers 1, 1, 1, 1, 1).
\[ G = 1 + 2 + 1 + 2 + 1 = 7 \]
\[ R = 1 + 1 + 1 + 1 + 1 = 5 \]
\[ S = 7 + 5 = 12 \]
A total of 12 falls in the 7–12 band, which corresponds to Type II.
Result: Fitzpatrick Type II — white, fair skin (usually burns, tans with difficulty).
How to Use the Calculator
- Answer the five questions under Your Natural Coloring (Genetic Score): Eye color, Natural hair color, Skin color of unexposed skin, Freckles on unexposed skin and Where were your ancestors from?. For skin color and freckles, check an area the sun rarely reaches, such as your inner upper arm.
- Answer the five questions under How Your Skin Reacts to the Sun (Reaction Score), thinking about your first strong summer exposure without sunscreen.
- Read your Genetic disposition score (0–20), Sun reactivity score (0–20) and Total questionnaire score (0–40).
- Check your Fitzpatrick skin type (I–VI) and the What Your Type Means panel for interpretation and sun-protection advice.
What Is the Fitzpatrick Skin Type Scale?
The Fitzpatrick scale, introduced by dermatologist Thomas Fitzpatrick in 1975, classifies skin into six types based on how it responds to ultraviolet (UV) radiation — specifically, how easily it burns and how well it tans. Type I skin is ivory-white, always burns and never tans; Type VI skin is dark brown to black, never burns and tans profusely. The scale was originally developed to predict how patients would react to phototherapy, and it remains a standard tool in dermatology and aesthetic medicine.
Because the scale describes sun reactivity rather than ethnicity or skin color alone, it combines two kinds of information. Your genetic coloring (eyes, hair, unexposed skin, freckling, ancestry) gives a rough starting point, while your actual burning and tanning history is the more reliable predictor. That is why this questionnaire asks both: two people with similar coloring can react quite differently to the sun.
Interpreting your result is straightforward: the lower your type number, the less natural UV protection your skin has and the more careful you need to be. Type I and II skins should use SPF 30+ daily and avoid midday sun; Type III and IV skins still accumulate sun damage even though they tan; Type V and VI skins burn rarely but are not immune to UV damage — and melanoma in darker skin often appears on the palms, soles or nail beds, where it is frequently found late.
Practically, the scale is used by laser and IPL clinics to select safe treatment settings, by dermatologists to plan phototherapy doses, and by anyone trying to gauge how long they can stay in the sun. To plan actual time outdoors, combine your skin type with the current conditions using our UV Index sunburn time calculator, and compare sunscreen products with the SPF UVB protection calculator.
Fitzpatrick Types at a Glance
| Type | Score | Typical skin color | Burns | Tans |
|---|---|---|---|---|
| I | 0–6 | Ivory / pale white | Always | Never |
| II | 7–12 | White, fair | Usually | With difficulty |
| III | 13–18 | White to beige-olive | Sometimes mildly | Gradually, to light brown |
| IV | 19–24 | Light brown, olive | Rarely | Easily, to deep brown |
| V | 25–30 | Brown | Very rarely | Deeply and profusely |
| VI | 31–40 | Dark brown to black | Never | Profusely, very dark |
Limitations and Tips for Accurate Results
- Use your natural coloring. Answer with your untreated hair color and unexposed skin — dyed hair or a suntan will distort the genetic score.
- Base reactions on real experience. Think of how your skin behaved during strong summer sun without sunscreen, ideally from memory of several seasons, not a single day.
- It is a self-assessment, not a diagnosis. The questionnaire estimates sun reactivity only; it does not measure overall skin health. If you notice a mole or spot that is new, changing, bleeding or unusual, see a doctor regardless of your type.
- Not a pure ethnicity measure. Ancestry is only one of ten questions, because people from the same background can have very different sun responses.
- Sun protection is never zero. Even Type VI skin accumulates UV damage; it simply burns less readily. Reapply sunscreen after swimming or sweating, and remember that UV also ages skin and raises long-term cancer risk for every type.
Frequently Asked Questions
How do I calculate my Fitzpatrick skin type by hand?
Score each of the 10 questions from 0 (lightest coloring, most sun-sensitive) to 4 (darkest, most sun-resistant). Add the first five answers for your genetic score \(G\) and the last five for your reaction score \(R\). The total \(S = G + R\) maps to a type: 0–6 is Type I, 7–12 is Type II, 13–18 is Type III, 19–24 is Type IV, 25–30 is Type V and 31–40 is Type VI.
Which Fitzpatrick skin type is most common?
Type III is the most common worldwide and is often considered the average — skin that sometimes burns mildly and tans gradually to light brown. In Northern Europe, Type II is very frequent, while in much of Asia, Africa and Latin America Types IV–VI dominate. All six types are normal; the number only reflects how your skin reacts to UV radiation, not health or attractiveness.
Can my Fitzpatrick type change over time?
Your underlying type is genetic and lifelong, but your measured score can shift. Repeated sun exposure thickens the skin's outer layer and increases pigment, so someone who once burned quickly may later tolerate more sun. Also, moving to a sunnier climate or indoor tanning can change your answers. For the most accurate result, base your answers on your natural coloring and long-term burning and tanning history, not a recent tan.
Is the Fitzpatrick scale accurate for all ethnicities?
It has known limitations. The scale was built around how skin burns and tans, so it works best when answered from actual sun experience. For people with deeply pigmented skin, differences between Types V and VI can be hard to distinguish and less clinically relevant. Also, mixed-ancestry individuals often fall between categories — in that case, your real burning history matters more than your ancestry answer.
Why do laser and IPL clinics ask for my Fitzpatrick type?
Melanin absorbs laser and IPL energy, so darker skin types risk burns, blisters or pigment changes at settings safe for lighter skin. Clinics use your type to select wavelengths, fluence and cooling. This questionnaire gives a good self-estimate, but a clinic will confirm it during your consultation — be honest about tanning habits too, because a recent tan can temporarily change your effective type.
What SPF should my skin type use?
As a general rule: Types I–II should use broad-spectrum SPF 30+ daily and avoid midday sun; Types III–IV SPF 15–30 in strong sun; Types V–VI SPF 15+ during long exposure. These are guidelines, not a diagnosis — adjust for the UV index, altitude, reflection from water or snow, and your own burning history. If a rash or unusual reaction appears after sun or sunscreen use, consult a dermatologist.
What if my genetic score and reaction score disagree strongly?
That happens and is expected — two people with the same coloring can react differently to the sun. Trust the reaction score more: actual burning and tanning history is the more reliable predictor of UV sensitivity, which is why it carries equal weight in the total. If your answers pull in opposite directions, revisit the reaction questions using memories from several summers rather than one unusual day, and answer with your natural, un-tanned coloring.
