How to Read a Leggings Size Chart Properly
June 18, 2026 · Alo Editorial · 3 MIN READ
A size chart has everything you need and almost nobody reads it correctly. Here is what each measurement means and how to match it to your body.
Size charts are the most-skipped and most-useful part of a product page. They contain the exact measurements that decide fit, and they are written in a language most shoppers never learn. This guide translates them.
The measurements that matter
- Waist: the circumference at the top of the waistband, not your natural waist.
- Hip: the circumference at the widest point, usually 20cm below the waist.
- Inseam: crotch to hem, which decides where the legging lands on your leg.
- Rise: crotch to the top of the waistband, which decides where it sits on your torso.
The waist measurement on a chart is the garment measurement, not your body measurement. A legging with 30% stretch will have a garment waist several centimetres smaller than the body waist it fits, because the fabric is meant to stretch to you.
How to match them
- 01Measure your waist and hip with a tape, snug but not pressing.
- 02Find your hip measurement first: it is usually the deciding one.
- 03Check that your waist falls within the same size range.
- 04Compare rise and inseam against a pair you already own.
- 05If your two measurements span sizes, take the larger and check the rise.
The stretch factor
Charts sometimes list a stretch range or a fit note. A high-stretch legging can fit two sizes of body, which is why the same person can be a small in one brand and a medium in another. When a chart lists body measurements rather than garment measurements, match directly. When it lists garment measurements, add the stretch back.
What to check before you buy for how read leggings size chart
Two pieces can look identical on the hanger and behave differently in how read leggings size chart. The checks below are the ones that catch it early. Black Airbrush High-Waist Fast Track Legging is the piece we would test them against first.
- Squat test in a mirror: the fabric should go opaque, not sheer.
- The waistband should sit flat at your natural waist without rolling when you fold forward.
- Check the inseam against your height — a 7/8 length on a tall frame is a crop.
What charts do not tell you
Charts cannot tell you how a fabric feels at its stretch limit, whether the waistband rolls, or how the rise interacts with your torso. Those require either reviews or trying the garment. The chart gets you to the right size; the rest is judgement.
The chart is a translation layer. Learn to read it once and sizing stops being a guess.
FREQUENTLY ASKED QUESTIONS
- Are size chart measurements the garment or my body?
- Usually the garment, laid flat. Because activewear stretches, the garment measurement is smaller than the body it fits. Some charts list body measurements instead, so check the chart notes.
- Which measurement decides my size?
- Usually the hip. Find your size by hip first, then check that your waist falls in the same range. It is the sort of difference you notice twenty minutes in, not on the hanger.
- What if my waist and hips are different sizes?
- Take the larger size and check the rise and waistband. A legging that fits the hips but cuts in at the waist is worse than one slightly loose at the hip.
