Check whether the tape is at the same landmark and angle, and whether posture and tension match. Record duplicate readings to see whether the method is repeatable.
A repeatable tape check
Make tape measurements comparable
When two readings disagree, check the landmark, tape angle, tension and posture before interpreting the difference as body change.
| Date and site | Landmark / conditions | Reading 1 | Reading 2 | Reading 3 if needed | Unit and note |

The repeatability checklist
Keep one definition per series. A reading at the navel should not be silently compared with a reading at the narrowest waist.
- Mark or describe the exact landmark. Do not switch between clothing size, bone width and circumference.
- Stand the same way for each reading and keep the tape level without compressing the skin.
- Use the same unit and tape, and note unusual conditions.
- Take two readings after fully repositioning the tape. If they differ, take a third and record all readings instead of selecting your preferred one.
Decide what to keep
The worksheet below keeps the raw readings visible. A large spread suggests checking the setup again. There is no universal correction that can recover a mismatched landmark or unit.

Common questions
Keep the original and note why it may not be comparable. A later repeat under the written protocol is more useful than silently changing the record.
