A practical tape-measure guide for body shape results, fit checks, and common measurement mistakes.
Measure over the same base layer
Use a flexible tape over light clothing or directly over the body. Thick fabric changes shoulder, bust, waist, and hip readings enough to change the classification.
Keep the tape level
Most wrong results come from angled tape. Use a mirror, measure twice, and record the average if two readings are close but not identical.
Use the result for fit context
Body shape is best for comparing proportions and choosing where to start with size charts. It is not a medical assessment and should not replace health metrics.
The fastest way to make a calculator page useful is to show when the number is reliable, when it is only a rough estimate, and what to do next.
