How to measure height at home
Use a flat floor and wall, remove shoes, stand upright and use a rigid book or ruler to mark the top of the head. Record the measurement and its date consistently; an app stores a reading but cannot verify your measuring technique.
Set up the measurement carefully
For children who can stand, CDC guidance recommends removing shoes and headwear, standing on a firm floor against a flat wall, looking straight ahead, and placing a rigid book or ruler at a right angle to the wall. Mark its underside at the top of the head and measure from the floor with a metal tape. A second person can help align and read the mark.
Make each entry understandable
Choose a unit and keep it consistent in your records. Write the date alongside the value. If you change equipment or notice an error, keep a note in your own measurement record instead of silently treating the result as growth.
For example, a personal log could contain a date, the value in centimeters and a note saying shoes removed. This is a logging example, not a claim that Tallify has a dedicated field for every note. Use the measurement controls available in your version of the app.
Read the graph without overinterpreting it
A measurement history answers what you recorded and when. A completion chart answers which daily actions you logged. Neither chart, by itself, establishes why a number changed. Do not attribute a difference to an exercise simply because it followed a workout.
If a value looks implausible, check the unit and entry before changing your goals. A typo should not become a milestone. Keep the record useful for comparison instead of repeatedly adjusting it to produce a smoother graph.
Know when a tracker is not enough
Tallify is a personal tracking and wellness tool, not a clinical growth assessment. Questions about a child's growth pattern, delayed development or unexplained changes belong with a qualified healthcare professional. Bring an honest record of measurements if you have one; do not rely on an app score as a diagnosis.
