Shopping for activewear above an Australian 16 online involves a specific frustration: the size exists on the dropdown, arrives, and fits nothing like the same letter did from a different brand. That is not you misjudging. It is a real structural problem in how the category is sized.
Why XL means four different things
Most activewear sold online is manufactured in Asia and cut on an Asian sizing block, which is drafted one to two sizes smaller through the waist and hip than an Australian or US block. A brand can list S through 3XL and still top out around an Australian 16.
Very few listings say which block they used. So the same letter can mean:
- XL on an Asian block — roughly an Australian 14
- XL on an Australian block — roughly an Australian 16
- XL on a US block — roughly an Australian 16–18
- XL in a dedicated plus range — anywhere from 18 to 22
The fix is to ignore letters entirely and work from your measured waist and hip against the brand's chart. Our Australian sizing guide has the full conversion table and how to read a chart that gives garment measurements rather than body measurements.
The four things that matter more above XL
1. Waistband width
A narrow band creates a pressure line, and the larger the garment, the more load that line carries. Below about 10cm it will roll, and no amount of sizing up fixes a band that is too narrow for the job. Look for wide, and look for a band that is the same dense knit as the rest of the legging rather than a thin elastic casing.
2. Knit density under stretch
Fabric that reads as opaque on a mannequin can go translucent when stretched across a larger area. This is straightforward physics and it is the most common complaint about cheap plus-size activewear.
Test it the same way as any other legging: stretch the fabric over your hand and hold it to a light. If you see clear definition, it will go sheer in a squat. Denser knits, in the 240–300 GSM range, hold up.
3. Gusset construction
A diamond or triangular gusset at the crotch distributes strain across several seams instead of one intersection. Without it, four seams meet at a single point that takes the entire load every time you sit, squat or lunge. That point is where leggings fail first, and it fails sooner the more fabric is pulling on it.
Most listings do not mention a gusset. Zoom into the product photos — you can usually see it.
4. Inseam and thigh chafe
Shorts are where the plus-size market fails most often. A 10cm inseam that works on one body rides straight up on another, and the resulting chafe ends a walk early. Measure where your thighs actually touch and buy an inseam that sits below it. Our guide to stopping thigh chafe covers the other fixes.
What to be sceptical of
Ranges that stop at XL but call themselves inclusive. An XL on an Asian block is an Australian 14. That is not a plus size range.
Different fabric in the larger sizes. Some brands quietly switch to a cheaper knit or fewer colourways above XL. If the 3XL comes only in black while everything else has eight colours, that tells you where it sits in the brand's priorities.
Photography that stops at a size 10. If a brand sells to 4XL and every photograph is on a straight-size model, you have no information about how the garment actually sits.
Where our range runs to
Our plus size activewear page lists each style against its actual maximum size, so you can see at a glance which pieces run to 5XL and which stop at 2XL. Everything is the same fabric and the same colourways as the smaller sizes.
These are cut on an Asian block, and we say so on every product page rather than leaving you to discover it after delivery. If you are between sizes, take the larger one, and there are 30 days to return anything unworn if the fit is wrong.
