What it calculates

The β€œEASI” calculator computes EASI from 21 parameters: age 0–7 years (1 = yes), head/neck: erythema (0–3), head/neck: edema/papulation (0–3), head/neck: excoriations (0–3), head/neck: lichenification (0–3), head/neck: affected area (%), upper limbs: erythema (0–3), upper limbs: edema/papulation (0–3), upper limbs: excoriations (0–3), upper limbs: lichenification (0–3), upper limbs: affected area (%), trunk: erythema (0–3), trunk: edema/papulation (0–3), trunk: excoriations (0–3), trunk: lichenification (0–3), trunk: affected area (%), lower limbs: erythema (0–3), lower limbs: edema/papulation (0–3), lower limbs: excoriations (0–3), lower limbs: lichenification (0–3), lower limbs: affected area (%).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Age 0–7 years (1 = yes) = 0, Head/neck: erythema (0–3) = 1, Head/neck: edema/papulation (0–3) = 1, Head/neck: excoriations (0–3) = 1, Head/neck: lichenification (0–3) = 0, Head/neck: affected area = 10 %, Upper limbs: erythema (0–3) = 2, Upper limbs: edema/papulation (0–3) = 2, Upper limbs: excoriations (0–3) = 1, Upper limbs: lichenification (0–3) = 1, Upper limbs: affected area = 30 %, Trunk: erythema (0–3) = 1, Trunk: edema/papulation (0–3) = 1, Trunk: excoriations (0–3) = 0, Trunk: lichenification (0–3) = 0, Trunk: affected area = 5 %, Lower limbs: erythema (0–3) = 2, Lower limbs: edema/papulation (0–3) = 1, Lower limbs: excoriations (0–3) = 1, Lower limbs: lichenification (0–3) = 1, Lower limbs: affected area = 20 % the result is 8.8 (Area score: 0%=0, <10%=1, 10–29=2, 30–49=3, 50–69=4, 70–89=5, β‰₯90=6).

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)Β². Example: 70 kg / (1.75 m)Β² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
