Toddler Growth Chart: Height and Weight From 1 to 3 Years for Boys and Girls (WHO Standards, 2026)

18 min

Quick Answer

At 1 year, the average boy weighs about 9.6 kg and is 75.7 cm long; the average girl weighs 8.9 kg and is 74 cm. By 3 years, boys average 14.3 kg and 96.1 cm, and girls 13.9 kg and 95.1 cm. Anything between the 3rd and 97th percentile is usually normal. Steady growth matters most.

Toddler Height and Weight at a Glance (WHO Averages)

Age	Boys: Weight	Boys: Height	Girls: Weight	Girls: Height
1 year (12 months)	9.6 kg	75.7 cm	8.9 kg	74.0 cm
1.5 years (18 months)	10.9 kg	82.3 cm	10.2 kg	80.7 cm
2 years (24 months)	12.2 kg	87.1 cm*	11.5 kg	85.7 cm*
2.5 years (30 months)	13.3 kg	91.9 cm	12.7 kg	90.7 cm
3 years (36 months)	14.3 kg	96.1 cm	13.9 kg	95.1 cm

*Averages are the WHO 50th percentile. From 2 years, height is measured standing, which reads about 0.7 cm less than lying-down length. Source: WHO Child Growth Standards.

Key Facts Every Parent Should Know

India uses WHO charts for children under 5: The Indian Academy of Pediatrics and the Government of India use WHO standards for growth assessment under 5 years (IAP)
About 2.5 kg and 12 cm: The typical weight and height gain between 1 and 2 years (WHO averages)
About 2 kg and 9 cm: The typical gain between 2 and 3 years
3rd to 97th percentile: The range where most healthy children fall
Growth slows after age 1: So appetite often drops too, which is normal
The trend matters more than one reading: Doctors look at whether your child follows their own curve

What Is the Growth Chart for Boys From 1 to 3 Years?

Short answer: Most healthy boys aged 1 to 3 years fall between the 3rd and 97th percentile. At 1 year, that's about 7.8 to 11.8 kg and 71 to 80 cm. At 3 years, it's about 11.4 to 18.0 kg and 89 to 103 cm.

What Is the Growth Chart for Girls From 1 to 3 Years?

Short answer: Most healthy girls aged 1 to 3 years fall between the 3rd and 97th percentile. At 1 year, that's about 7.1 to 11.3 kg and 69 to 79 cm. At 3 years, it's about 11.0 to 17.8 kg and 88 to 102 cm.

How Do I Read a Growth Chart Percentile?

Short answer: A percentile compares your child with 100 healthy children of the same age and sex. 50th percentile means average. 25th percentile means your child is heavier or taller than 25 children and lighter or shorter than 75. Anywhere from the 3rd to the 97th percentile is usually normal.

Percentile	What It Means
Below 3rd	Smaller than 97 out of 100 children. Talk to your doctor.
3rd to 15th	On the smaller side, usually normal if growth is steady
15th to 85th	Typical range
85th to 97th	On the bigger side, usually normal if growth is steady
Above 97th	Bigger than 97 out of 100 children. Talk to your doctor.

A low or high percentile isn't a problem on its own. A child who stays on the 10th percentile, growing steadily, is often perfectly healthy. Small parents often have small children.

How Much Should a Toddler Grow Each Year?

Short answer: Growth slows after the first birthday. Between 1 and 2 years, toddlers usually gain about 2.5 kg and grow about 12 cm. Between 2 and 3 years, they gain about 2 kg and grow about 9 cm.

Period	Average Weight Gain	Average Height Gain
Birth to 1 year	About 6 kg (weight roughly triples)	About 25 cm
1 to 2 years	About 2.5 kg	About 12 cm
2 to 3 years	About 2 kg	About 9 cm

Calculated from WHO average (50th percentile) values.

Why is my toddler eating less? Because growth slows after age 1, appetite naturally drops too. Read our guide on picky eating and food refusal in toddlers.

How Do I Measure My Toddler at Home?

Short answer: Weigh your toddler on the same scale each time (weigh yourself holding them, then subtract your weight). Measure height lying down until age 2 and standing from age 2, without shoes, against a wall.

Measurement	How to Do It
Weight	Weigh yourself, then weigh yourself holding your child. Subtract the two. Use the same scale and similar clothing each time.
Length (under 2)	Lay your child flat, head touching a wall, legs straight. Mark the heel and measure.
Height (2 and older)	Stand your child against a wall, barefoot, heels together, looking straight ahead. Place a book flat on their head and mark.
How often	Monthly is plenty. Weekly readings can be confusing.

For accurate tracking, use the measurements from your pediatrician or Anganwadi visits. In India, the Mother and Child Protection (MCP) card given at Anganwadis includes a growth chart.

What Affects a Toddler's Height and Weight?

Short answer: Genes (parents' height), nutrition, illness, sleep, birth weight or prematurity and activity all affect growth. Short-term dips during illness are common and usually catch up.

Factor	How It Affects Growth
Parents' height and build	The biggest factor for height
Nutrition	Enough calories, protein, iron, calcium and vitamin D are needed
Frequent illness or diarrhoea	Can slow weight gain temporarily
Worms	Can reduce appetite and nutrient absorption (worms in toddlers)
Prematurity or low birth weight	Use corrected age until 2; many catch up by 2 to 3 years
Too much milk	Can reduce appetite for food and lower iron
Sleep	Growth hormone is released during deep sleep
Medical conditions	Thyroid, gut or heart problems can affect growth (rare)

When Should I Worry About My Toddler's Growth?

Short answer: Talk to your doctor if your child is below the 3rd or above the 97th percentile, drops across 2 major percentile lines (for example from the 50th to below the 15th), hasn't gained weight for 2 to 3 months, or is losing weight.

Red Flag	Why It Matters
Below the 3rd percentile for weight or height	May point to undernutrition or a medical condition
Above the 97th percentile for weight	May point to overweight
Crossing 2 major percentile lines downward	Growth faltering, needs a check
No weight gain for 2 to 3 months	Could relate to diet, illness or worms
Weight loss	Always needs a check
Height falling behind while weight is normal	Doctors check for hormone or other causes
Very fast weight gain	Can lead to obesity later

Underweight, Stunting and Wasting: What Do They Mean?

Term	What It Means
Underweight	Low weight for age
Stunting	Low height for age, a sign of long-term undernutrition
Wasting	Low weight for height, a sign of recent weight loss or acute undernutrition
Overweight	High weight for height

These are common concerns for Indian children, which is why regular growth monitoring at check-ups and Anganwadis matters. If your child is underweight, read what to do if your toddler is underweight.

How Can I Support Healthy Growth?

Short answer: Offer 3 meals and 2 snacks of varied home food, keep milk to about 300 to 500 ml a day, include iron and protein, ensure enough sleep, deworm every 6 months and keep up with check-ups and vaccines.

Habit	Why It Helps
Varied home food: dal, roti, rice, vegetables, fruit, curd, eggs, paneer	Balanced nutrition
Iron-rich foods: ragi, dal, spinach, eggs, rajma	Prevents anaemia, supports growth
Milk 300 to 500 ml a day	Enough calcium without crowding out food
Limit sugar and junk food	Avoids empty calories and poor appetite
11 to 14 hours of sleep (1 to 2 years)	Supports growth hormone
Deworming every 6 months	Prevents nutrient loss
Active play every day	Builds strength and healthy appetite
Regular growth checks	Catches problems early

What Should Indian Parents Keep in Mind?

Short answer: Use WHO charts (as IAP recommends), track the trend rather than single numbers, don't compare with cousins, and use free Anganwadi growth monitoring.

Common Belief	Better Approach
"A chubby baby is a healthy baby"	Steady growth within the normal range matters, not chubbiness
"She's small, so give her a health drink"	Talk to your doctor; real food is better than sugary drinks
"Our cousin's child is much bigger"	Compare with growth charts, not other children
Weighing the child every week	Monthly readings are enough
"He doesn't eat, so he must be underweight"	Check the chart first; many picky eaters grow normally
Ignoring a percentile drop	Talk to your doctor if your child crosses 2 percentile lines

Myths vs Facts

Myth	Fact
"The 50th percentile is the target"	Anywhere from the 3rd to 97th percentile is usually normal
"Indian children need different charts under 5"	IAP and the Government of India use WHO charts under 5 (IAP)
"Bigger is always healthier"	Steady growth along a curve is what matters
"A drop in appetite means a growth problem"	Growth slows after 1, so appetite naturally drops
"One low reading means my child is underweight"	Doctors look at the trend over several readings
"Tonics make toddlers grow taller"	Height depends mostly on genes, nutrition and sleep
