Toddler Weight Percentile Calculator (2–5 Years)

Toddler weight gain naturally slows dramatically after age 1. While babies gain about 7 kg in their first year of life, toddlers typically gain only 1.5–2.5 kg per year from ages 1–5. This is completely normal. If your child is eating well, active, and tracking their own percentile curve, the slower gain is not a concern.

Any percentile between the 3rd and 97th is within the normal WHO range. The key is consistency — a toddler who has been at the 25th percentile throughout their first two years is expected to remain near the 25th, not jump to the 50th. Tracking the trend matters more than the absolute number.

Picky eating is extremely common in toddlers and rarely causes significant weight faltering if the child is growing along their percentile curve. Offer a variety of foods without pressure. If the child has dropped two or more major percentile lines, or if you're genuinely concerned about intake, consult your pediatrician.

There is a smooth transition at 24 months. WHO publishes separate tables for 0–2 years (recumbent measurement) and 2–5 years (standing measurement). This calculator uses the 2–5 year WHO growth standards, which are based on standing weight (which has not changed). The same scale is used for both.

Below the 5th percentile is monitored more closely. Below the 3rd percentile may be labelled 'low weight for age,' but not all children below this line have a health problem — some families are genetically small-framed. Your pediatrician will also consider the child's length, overall wellbeing, and rate of growth.

Yes. The WHO growth chart was created from data collected across 6 countries (Brazil, Ghana, India, Norway, Oman, United States) under conditions that support optimal growth — good nutrition, non-smoking households, breastfed infants. These charts represent a prescriptive standard (how children SHOULD grow) rather than a descriptive norm (how average children do grow).
