Step by step
How to measure your waist correctly
An off measurement by even half an inch can mean the wrong size — and the wrong size means poor results. Take 60 seconds and do this right.
1
Find your natural waist
Stand upright and locate the narrowest part of your torso — usually just above your belly button and below your ribs.
2
Use a soft tape measure
Use a flexible measuring tape, not a rigid ruler. No tape? Use a piece of string, then measure the string against a ruler.
3
Breathe naturally
Do not suck in your stomach or hold your breath. Measure at a relaxed, natural exhale for the most accurate reading.
4
Keep it level and snug
The tape should sit flat all the way around — not tight enough to dig in, and not loose enough to gap.
5
Measure twice
Take two readings to confirm. If they differ, use the larger number — better to size up than order something too tight.
6
Note both units
Write down your measurement in both inches and centimetres so you can cross-reference the chart below without converting.

Fit tips before you order
↕
Between two sizes?
Size down for a firmer sculpting effect. Size up if you're new to waist training or plan to wear it all day.
✕
Ignore clothing sizes
Your dress size or jean size does not determine your Sculptah size. Always go by your tape measurement.
☀
Measure in the morning
Your waist is naturally slimmer before meals. Morning measurements give the most consistent, reliable baseline.

Sizing down over time
As you progress, you may move down a size. The adjustable hooks let you track that change without buying a new trainer.
