Common Height Measurement Mistakes to Avoid
A few small errors can affect your measurement:
- Wearing shoes: Shoe soles add height, so measure barefoot.
- Using a sloping floor: Uneven surfaces can produce an inaccurate result.
- Tilting the measuring tape: Keep the tape vertical rather than measuring diagonally.
- Positioning the book at an angle: Keep the book level and perpendicular to the wall.
- Rounding too early: Record the measurement in inches or centimeters before converting it to another unit.
Your height can also vary slightly during the day because the discs between your spinal bones compress under normal daily loading. For the most consistent comparison, measure yourself under similar conditions each time.
