Yoga Wear Size Charts That Reduce Returns
Garment measurements, not body sizes - the size chart format that cuts activewear returns: flat-lay measurements with tolerance, stretch ranges, fit intent per style, and the two photos every product
Most activewear size charts fail before a customer ever reads them, because they answer the wrong question. A chart that says "size M fits 130-150 lbs" is guessing about a body. A chart that says "size M: 27 cm waistband height, 68 cm hip width, lies flat" is describing a garment - and customers with a tape measure and two minutes can decide for themselves. The second chart is why some brands return almost nothing.
Here is how to build the kind that reduces returns, and what to put around it.
Measure the Garment, Not the Body
Body-based charts stack two uncertainties: your grading accuracy and the customer's self-knowledge. Garment-based charts remove one entirely - every measurement is a fact about the product, taken flat-lay with a tolerance stated. Customers compare against a piece of clothing they already love (the single most accurate fitting tool ever invented), and the returns drop accordingly.
The measurements to publish per style: waistband width (relaxed and stretched), hip width at the widest point, rise, inseam and total length for bottoms; band width, cup depth indication and length for bras and tops. The measurement points are the same ones from your tech pack spec - which is one more reason the pack deserves real numbers, per the tech pack guide.
State Stretch, Not Just Size
Two leggings with identical flat measurements behave completely differently if one knit is denser or the spandex count differs. The fix is a stretch line in the chart: how far the waistband comfortably stretches (a real measurement - pull it and record), and a plain-language fit intent: "compression - should feel snug" or "relaxed - true to your usual size." Fit intent is also a grading input, as covered in the size grading guide: what you claim per size has to be engineered per size.
Fit Intent Per Style, Not Per Brand
"Runs small" and "runs large" reviews usually trace to a brand-level chart applied across styles with different intents. A compression legging and a relaxed flare pant in the same size should NOT fit the same body the same way - and your chart should say so, per style. Write one fit sentence per style on the product page: who it is cut for, how it should feel, and what to do between sizes (usually: size up for loungewear fits, stay down for compression).
The Two Photos That Cut Returns Further
- The flat-lay photo with the measurement points marked - customers see exactly where 68 cm hip width was measured, and wrong assumptions disappear.
- The on-body photo with the model's stats stated (height, the size she wears). Customers pattern-match against a body, and stating the size removes the guesswork. Between the marked flat-lay, the stated stretch and the referenced body, a customer who still orders the wrong size is rare - and the returns that remain trace to real fit faults you want to know about anyway.
Common Questions
What tolerance should the chart state?
The same tolerance you hold your factory to - commonly plus or minus half a centimeter on knit garments. Publishing the tolerance also documents it: the chart becomes part of your spec discipline.
Do size charts differ per fabric?
Yes - that is the stretch point above. A dense sculpt knit and a buttery brushed knit in the same graded size will measure and feel different. Chart each style from its own garment, never copy-paste across fabrics.
How do I build the chart if my factory only gives body sizes?
Ask for the garment measurement spec per size - any factory that grades properly has it (the graded size set IS the source). If a supplier cannot produce garment measurements, that is a verification red flag of its own.
A Chart Is a Promise You Measure
Size charts reduce returns when they describe the garment - flat measurements with tolerances, stated stretch, fit intent per style, and photos that show where the numbers came from. It is more work than copying a body-size table, and it is the kind of work that shows up in your return rate and your reviews.
