What is a tape measure and how should it be used for body measurements?

Overview

A tape measure is a flexible measuring tool marked in units such as inches or centimeters. It is used to measure lengths and circumferences of the body. When used correctly, it is both reliable (repeatable) and accurate — research has shown it to be more reliable than skinfold thickness measurements.

However, accurate tape measure results depend on proper technique and standardization.

Steps / Details

To ensure consistent and accurate measurements:

1. Position correctly – Follow standardized body positioning for each measurement site.
2. Identify anatomical landmarks – Locate the correct measurement site on the body before placing the tape.
3. Use millimeters – Record measurements in millimeters for precision.
4. Keep the tape on the skin – Rest the tape directly against the skin without compressing or indenting it.
5. Keep the tape at 90 degrees – The tape should be perpendicular to the long axis of the body segment being measured.

Notes

• Following these steps supports both intrarater reliability (same person measuring consistently) and interrater reliability (different people getting the same result).
• Training and standardization are required before using a tape measure in a health or fitness assessment context.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the specific measurement site in question and the technique being used.
