Why nothing fits: India has been wearing American sizes, and INDIAsize is the fix
A national body-scanning survey of more than 25,000 people produced 27 size charts built on Indian bodies. Here is what changes.
If you have ever been a medium in one shop, a large in the next and an XL online, you have met the actual problem in Indian apparel retail: the size labels on the rack were not derived from Indian bodies.
Brands here have historically borrowed European or American size systems, or invented their own. The result is a market where a size label carries almost no information, and where industry estimates put apparel returns at roughly 30 to 40 per cent - with poor fit the most common reason given.
What INDIAsize did
The National Institute of Fashion Technology, under the Ministry of Textiles, ran one of the largest anthropometric studies the country has seen. Using 3D whole-body scanning, the survey measured more than 25,000 people aged 15 and above - around 26,300 in total - across six regions anchored on Delhi, Mumbai, Chennai, Hyderabad, Kolkata and Shillong.
Data collection completed in 2023. The statistical analysis produced 27 body-size charts - 13 for women and 14 for men - spanning three height groups and five body shapes, published for industry use through the INDIAsize portal.
The height-and-shape structure is the interesting part. A single chest measurement produces a garment that fits one body and hangs wrong on another with the same chest but a different height or torso shape. Charts that vary by both are what make ready-to-wear actually ready.
Why it matters beyond convenience
- Returns are expensive for everyone. The cost of reverse logistics is priced into what you pay, whether or not you return anything.
- Returned apparel frequently cannot be resold at full value, which makes fit failures an environmental problem as well as a commercial one.
- Smaller brands cannot afford their own fit research, so a public national standard lowers the barrier for them specifically.
- For shoppers, a common reference finally makes size labels comparable between brands - which is the whole point of a size label.
What to do while brands adopt it
Adoption takes time, so the practical advice is unchanged in the short term: buy by measurement, not by letter.
| Instead of | Do this |
|---|---|
| Picking your usual size | Read the brand size chart for that specific product |
| Trusting S / M / L | Compare chest, waist, hip and length in centimetres |
| Guessing between two sizes | Measure a garment you own that fits well, and match it |
| Assuming consistency within a brand | Check per product - a linen shirt and a knit polo are cut differently |
| Ignoring the model note | Read the height and worn-size line; it is the most useful sentence on the page |
What still will not be solved
A national chart standardises the reference, not the interpretation. Brands will still cut slim, relaxed and oversized fits from the same base size, and vanity sizing - labelling a larger garment with a smaller number - is a marketing decision no standard can prevent.
Fabric also has a vote. A rigid cotton shirt at your exact measurement fits differently from a stretch blend at the same numbers, and a heavy knit drapes differently from a light one. Those are the judgements that a size chart hands back to you.
Still, having a real national reference is a large improvement on a market where a size label was essentially decorative. Keep your own measurements written down, compare them to the chart on the page, and treat the letter on the tag as a rough hint.
