Kids Clothing Size Guide India — Complete Chart for Ages 0 to 6 Years (2026)
One of the most frustrating experiences in parenting is ordering clothes online only for them to arrive too small or too large. Indian children's clothing sizing is notoriously inconsistent across brands — a size 3 from one brand can fit like a size 2 from another. This comprehensive size guide takes the guesswork out of buying clothes for your baby or child aged 0 to 6 years, covering measurements, brand-specific sizing tips and practical advice for getting the right fit every time.
Why Indian Kids Clothing Sizes Are Confusing
Unlike adult clothing where standard measurements like chest and waist are widely used, children's clothing in India uses a mix of age-based sizing, height-based sizing and weight-based sizing — and different brands use different systems. Some brands label their clothing by age (2, 3, 4, 5, 6), others by height in centimetres (80cm, 90cm, 100cm, 110cm, 120cm) and others by a combination of both.
The result is that the same child can wear a size 3 in one brand, a size 4 in another and an 18–24M in a third. Add to this the fact that Indian children vary significantly in build — some are taller and leaner, others shorter and sturdier — and it becomes clear why sizing is such a common source of confusion and frustration for parents.
This guide gives you the measurements you need to find the right size regardless of which brand you are buying from.
How to Measure Your Child for Clothing
Before consulting any size chart, measure your child. You will need three measurements:
Height — stand your child against a wall with feet flat on the floor. Mark the top of their head and measure from the floor to the mark. For babies who cannot stand, lay them flat on a firm surface and measure from head to heel.
Chest — wrap a soft measuring tape around the fullest part of the chest, just under the armpits. Keep the tape snug but not tight. This is the most important measurement for tops and dresses.
Waist — measure around the natural waist, which for young children is typically at or just above the belly button. Keep the tape relaxed — children's waistbands need room to move.
For very young babies, weight is often the most reliable sizing guide since height and chest measurements change so rapidly in the first year.
Baby Clothing Size Chart — Ages 0 to 24 Months
This chart covers babysuits, rompers, onesies and general baby clothing. Use weight for newborns and young babies, then switch to height as your baby grows.
| Size Label | Age Range | Weight | Height |
|---|---|---|---|
| NB (Newborn) | 0 to 1 month | Up to 3.5 kg | Up to 52 cm |
| 0 to 3 M | 1 to 3 months | 3.5 to 6 kg | 52 to 62 cm |
| 3 to 6 M | 3 to 6 months | 6 to 7.5 kg | 62 to 68 cm |
| 6 to 9 M | 6 to 9 months | 7.5 to 9 kg | 68 to 74 cm |
| 9 to 12 M | 9 to 12 months | 9 to 10 kg | 74 to 80 cm |
| 12 to 18 M | 12 to 18 months | 10 to 12 kg | 80 to 86 cm |
| 18 to 24 M | 18 to 24 months | 12 to 14 kg | 86 to 92 cm |
Kiggle baby sizing note: Kiggle's baby range covers 0 to 24 months across their rompers, babysuits, tops and bottoms. Their sizing follows the standard chart above. As with all organic cotton garments, wash before first wear — Kiggle's products are pre-shrunk to minimise any further shrinkage.
Toddler and Kids Clothing Size Chart — Ages 2 to 6 Years
This chart covers t-shirts, tops, dresses, shorts, joggers and general kids clothing. Height is the most reliable measurement for this age group.
| Size Label | Age Range | Height | Chest | Waist |
|---|---|---|---|---|
| 2Y | 2 to 3 years | 86 to 98 cm | 52 to 54 cm | 48 to 50 cm |
| 3Y | 3 to 4 years | 98 to 104 cm | 54 to 56 cm | 50 to 52 cm |
| 4Y | 4 to 5 years | 104 to 110 cm | 56 to 58 cm | 52 to 54 cm |
| 5Y | 5 to 6 years | 110 to 116 cm | 58 to 60 cm | 54 to 56 cm |
| 6Y | 6 to 7 years | 116 to 122 cm | 60 to 62 cm | 56 to 58 cm |
Kiggle kids sizing note: Kiggle's kids range covers ages 2 to 6 years. Their sizing is designed for Indian children and runs true to the chart above. If your child is between sizes, Kiggle recommends sizing up — their garments are designed with room to move and a slightly larger size is more comfortable than one that is too snug.
Should I Size Up or Size Down?
This is the question parents ask most often. The general rule for children's clothing is:
Size up if:
- Your child is between two sizes
- You want the clothing to last longer — children grow fast and a slightly larger size will be worn for longer
- The brand is known to run small
- You are buying a close-fitting item like a t-shirt or babysuits
- You are buying for a gift and are not sure of the exact size
Size down if:
- The brand is known to run large
- You need the clothing for an immediate occasion and want a precise fit
- The item has adjustable features like drawstring waists that can compensate for extra length
For Kiggle's range specifically, sizing true to age works well for most children. If your child is on the taller side, size up.
Size Guide by Clothing Type
Different types of clothing fit differently and sizing can vary by garment type. Here is a quick guide:
Babysuits and rompers These are close-fitting all-in-one garments. Use weight for babies under 6 months and height for older babies. Babysuits that are too small are very uncomfortable as they restrict leg movement and pull on the shoulders. Always err on the side of slightly larger.
T-shirts and tops Chest measurement is most important here. A top that fits well in the chest will generally fit well overall. Length is secondary — a slightly longer top is perfectly wearable.
Dresses Height is the primary measurement. A dress should fall to approximately knee length for most occasions — use height to judge this. Chest measurement is secondary but important for fit around the body.
Shorts and bottoms Waist measurement is most important. Look for adjustable waistbands — Kiggle's bottoms use soft flat elastic waistbands that accommodate a range of waist sizes comfortably. Inside leg length matters for longer garments.
Hoodies and sweatshirts These are generally worn with more room than tops. Sizing by age or height works well. A hoodie that is slightly large on a child is perfectly wearable — children outgrow them quickly anyway.
How Indian Kids Compare to International Sizing
Many Indian parents buy clothing from international brands or online international retailers. Here is a quick comparison to help convert international sizing to Indian sizing:
| Indian Size | UK Size | US Size | EU Size | Height |
|---|---|---|---|---|
| 0 to 3 M | 0 to 3 M | 0 to 3 M | 56 to 62 | 52 to 62 cm |
| 3 to 6 M | 3 to 6 M | 3 to 6 M | 62 to 68 | 62 to 68 cm |
| 6 to 12 M | 6 to 12 M | 6 to 12 M | 68 to 80 | 68 to 80 cm |
| 12 to 18 M | 12 to 18 M | 12 to 18 M | 80 to 86 | 80 to 86 cm |
| 2Y | 2 to 3Y | 2T | 92 | 86 to 98 cm |
| 3Y | 3 to 4Y | 3T | 98 | 98 to 104 cm |
| 4Y | 4 to 5Y | 4T | 104 | 104 to 110 cm |
| 5Y | 5 to 6Y | 5T | 110 | 110 to 116 cm |
| 6Y | 6 to 7Y | 6 | 116 | 116 to 122 cm |
Important note: Indian children often have slightly different proportions than European and American children — typically shorter with a slightly broader waist relative to height. When buying from international brands, it is worth checking chest and waist measurements rather than relying purely on age or height.
Sizing Tips for Different Body Types
Indian children come in a wide range of builds and the standard size charts do not account for all of them. Here are some practical tips:
Taller children If your child is taller than average for their age, go by height rather than age in the size charts. A 3-year-old who is 106cm tall will fit better in a 4Y garment length-wise, even if the width is slightly large.
Shorter children Go by age or weight rather than height if your child is shorter than average. The chest and waist proportions of age-based sizing will typically fit better than height-based sizing.
Lean children Some children are tall but lean. Look for garments with adjustable waistbands — Kiggle's bottoms and many of their tops are designed with comfortable flat elastic that accommodates leaner frames without bunching.
Sturdier builds If your child has a broader chest or waist than average for their height, size up in the chest measurement. It is easier to deal with a garment that is slightly long than one that is too tight across the chest.
How Fast Do Children Grow — A Practical Guide for Buying Ahead
Understanding how fast children grow helps you decide how many clothes to buy and whether to buy ahead.
0 to 3 months: Babies grow extremely fast — approximately 3 to 4 cm per month. Newborn sizes are typically outgrown within 4 to 6 weeks. Do not overbuy in newborn or 0 to 3 month sizes.
3 to 12 months: Growth slows slightly but remains rapid — approximately 1.5 to 2.5 cm per month. Each size typically lasts 2 to 3 months.
1 to 2 years: Growth continues at around 1 to 1.5 cm per month. Each size typically lasts 3 to 4 months.
2 to 6 years: Growth slows further — approximately 6 to 8 cm per year. Each size typically lasts 6 to 12 months, making it more practical to buy ahead in this age range.
Practical buying tip: For babies under 12 months, buy what you need now plus one size up. Do not buy far ahead as you cannot predict exactly how fast your specific baby will grow. For children aged 2 to 6, buying one season ahead (end of summer sale for next summer, for example) is a practical way to save money.

Frequently Asked Questions
Why do children's clothing sizes vary so much between brands in India? There is no mandatory standardised sizing system for children's clothing in India. Each brand sets its own sizing based on their target market and fit preferences. This is why measuring your child and using the measurements rather than the size label gives more reliable results.
Should I wash clothes before checking the fit? Yes — always wash new children's clothing before the first wear and before assessing fit. Some garments shrink slightly on first wash, particularly those made from natural fibres like cotton. Kiggle's garments are pre-shrunk to minimise this but a first wash is still recommended.
My child is between two sizes — which should I choose? Size up. Children grow quickly and a slightly larger garment will last longer. For close-fitting garments like babysuits and t-shirts, the larger size will still look neat. Adjustable waistbands on bottoms can compensate for extra width.
How do I know if a garment will shrink after washing? Natural fibres like cotton can shrink slightly with heat. To minimise shrinkage: wash on a cool or warm cycle (30 to 40 degrees), avoid high heat tumble drying and air dry where possible. Kiggle's organic cotton garments are pre-shrunk and designed to maintain their size with normal care.
My child is 3 years old but very tall — what size should I buy? Go by height rather than age. If your 3-year-old is 108cm, they will fit a 4Y or 5Y in height-based sizing. The chest and waist measurements for a 4Y or 5Y label may be slightly large but adjustable waistbands and relaxed fits accommodate this well.
Do Indian kids sizes correspond to the number in years? Approximately, but not exactly. A size 3 is designed for an average 3-year-old but your specific child may fit a size 2 or a size 4 depending on their build. Always cross-reference with height and chest measurements for the best result.
Is there a size above 6Y in Kiggle's range? Kiggle currently makes clothing for ages 0 to 6 years. For children above 6 years, explore Kiggle's current range to see if the size 6 fits your child — many children wear Kiggle's size 6 well into their seventh year depending on their build.
Summary
Getting the right size for your child's clothing does not have to be a guessing game. Measure your child's height, chest and waist, consult the chart in this guide and use those measurements rather than relying on the age label alone. When in doubt, size up — children grow fast and a slightly larger garment is more comfortable and will last longer.
Kiggle's range of organic cotton clothing for babies and kids aged 0 to 6 years is designed with Indian children in mind, with sizing that is consistent, true to chart and designed to last through active childhood wear and frequent washing.
