Size charts that cut clothing returns: what to measure and how to show it

The return note says "too tight at the chest", and the buyer picked exactly the size your chart told them to. A size chart that cuts returns shows two sets of numbers for every size: the body it is meant for and the garment as it was actually stitched, measured flat. Beside them sits one plain line on how the fit should feel. The buyer's real question is not "what is a medium" but "will this sit on me the way I want", and only the gap between body and garment answers it.

Why a body-only chart sends parcels back

Many small labels start with a body chart copied from a big brand: S for a 36 chest, M for 38 and so on. The garment is then cut on a different pattern by a different karigar, and nobody checks the two against each other.

The buyer cannot see that gap. Worse, a "38" on an Indian kurta tag can mean a 38-inch body or a 38-inch garment, depending on who made it. A buyer with a 38 chest who receives a 38-inch garment has no room at all, and the kurta comes back. The difference between body and garment is called ease, and it decides whether the same size feels relaxed, regular or fitted. A chart that hides it is asking the buyer to guess.

What to measure, garment by garment

Measure the finished piece, not the pattern sheet, because cutting varies from batch to batch. Take three pieces of each size from the current batch and use the figure most of them agree on.

• Kurtas and tops. Chest, measured flat an inch below the armhole and doubled. Shoulder seam to seam. Length from the highest shoulder point. Sleeve length. Armhole, because "tight at the armhole" is the complaint that body charts do not predict. Hem width for A-line and anarkali cuts.
• Salwars, palazzos and churidars. Waist relaxed and fully stretched, if it is elastic. Hip. Length. For churidars, the ankle opening, since that decides whether a foot gets through.
• Readymade blouses. Bust, under-bust, shoulder, armhole, sleeve length and sleeve round, front and back neck depth. Then the seam margin left for alteration, because a buyer with a local tailor will order with that in mind.
• Men's kurtas and shirts. Chest, shoulder, length, sleeve and collar.

Round to the nearest half inch. A chart showing 39.37 inches tells the buyer it was converted, not measured.

How to show it on the product page

Here is the layout for one product, with illustrative numbers for a straight cotton kurta. They are not a standard; measure your own.

Under it, in plain words: "Relaxed, straight cut. If you are between sizes and want it closer to the body, take the smaller one." And one line about the photographs: "Model is 5 ft 6 in with a 34-inch chest and wears S."

Where it sits matters as much as what it says. Put the chart link right beside the size buttons, and open it over the page so the buyer does not lose their place. Make it text, not an image, so it can be read on a phone without pinching and found by search. Show centimetres alongside. If two products are cut differently, they get two charts.

For example, a chikankari label in Lucknow

Imagine an invented Lucknow label selling straight chikankari kurtas online. The numbers are made up. The owner copied a body chart from a large brand, so M said "fits 38 chest". But the M kurta, laid flat and doubled, measured 40. A buyer with a 38 chest got two inches of room in a style most buyers expect to wear loose. The size returns kept coming, 38 of 150 kurtas in a quarter at ₹140 a return, and the return notes said "tight" and "short in the sleeve".

The team changed the page before touching the pattern. They measured three pieces of every size and published both columns, laid out like the table above. M now said "fits 35 to 36 chest, garment 40", which sent the 38-chest buyers to L, with its 42-inch garment, where they belonged. A fit note was added: "Loose and airy. Size down only if you want it close." The sleeve length went into the chart as well.

They also started writing each return reason against its size in a sheet. Armhole complaints clustered in L. That was a pattern problem, so it went to the workshop, not into the chart. Over the next quarter, size returns fell from 38 to 22, and the rest were buyers who ordered two sizes on purpose.

When a size chart is not the fix

Skip the chart work if your returns are about colour, fabric feel or late delivery. Read the return reasons first and fix what they name. Free-size pieces such as dupattas, stoles and sarees need length and width, not a chart. Do not build a fit quiz or a size recommender before the basic chart is right, because it will only recommend the same wrong size more confidently. And if one batch's M is an inch bigger than the last, fix the cutting first; no chart can hide that.
