Kids Clothing Size Chart by Age: The Complete India Guide
From newborn to 8 years — height, chest and weight for every age, plus how to measure your child and choose the right size when you're buying online.
01 Kids clothing size chart by age
Use these charts as a general guide. They show the typical height, chest and weight for each age band — but every child grows differently, so always cross-check against your own measurements and the specific brand's chart before buying.
| Age | Height (cm) | Chest (cm) | Weight (kg) |
|---|---|---|---|
| 0–3 months | 50–60 | 40–43 | 3–6 |
| 3–6 months | 60–67 | 43–46 | 6–8 |
| 6–12 months | 67–76 | 46–48 | 8–10 |
| 12–18 months | 76–82 | 49–51 | 10–11 |
| 18–24 months | 82–88 | 51–53 | 11–12 |
| Age | Height (cm) | Chest (cm) | Weight (kg) |
|---|---|---|---|
| 2–3 years | 88–98 | 53–55 | 12–14 |
| 3–4 years | 98–104 | 55–57 | 14–16 |
| 4–5 years | 104–110 | 57–59 | 16–18 |
| 5–6 years | 110–116 | 59–61 | 18–20 |
| 6–7 years | 116–122 | 61–64 | 20–23 |
| 7–8 years | 122–128 | 64–67 | 23–26 |
These are approximate, industry-typical ranges for Indian kidswear. Treat them as a starting point, not an exact rule — confirm with measurements.
02 Why you shouldn't buy by age alone
The age on a label is a convenience, not a promise. A "2–3 Years" garment from one brand can be noticeably bigger or smaller than the same label from another, because there's no single enforced standard across kidswear. Two children of the same age can also differ by a full size in height and build.
That's why the age band is only ever your starting point. The numbers that actually decide fit are your child's height, chest and waist — and those you measure once and reuse.
"Buy for the measurement, not the birthday. The age label gets you to the right page; the measurements get you the right fit."
03 How to measure your child correctly
You need a soft measuring tape and about two minutes. Measure over light clothing, keep the tape snug but not tight, and write the numbers down so you can reuse them.
The three measurements that matter
- Height — stand your child against a wall, heels down, and measure from the top of the head to the floor.
- Chest — measure around the fullest part of the chest, under the arms, keeping the tape level.
- Waist — measure around the natural waistline, where trousers or a skirt would sit, without pulling tight.
Match the largest of your child's measurements to the size chart. If their height suggests one size but their chest suggests the next size up, go with the larger — clothes that are slightly roomy are far more wearable than ones that are tight.
04 When in doubt, size up
Children grow in spurts, not at a steady pace. A garment that fits perfectly today can be snug in two months. When a measurement falls between two sizes, choose the larger one. A little room means the piece lasts a whole season instead of a few weeks — better value, and more comfortable for an active child.
Sleepwear and swimwear are the one place not to over-size — they're designed to fit close for safety and function. For everyday wear, though, sizing up is almost always the smart call.
05 A quick checklist before you order
Confirm three things: you've matched your child's measurements (not just age) to the chart, you've sized up if they're between sizes, and you've checked the brand's return policy in case the fit surprises you. Get those right and online sizing stops being a gamble.
