Add readings, read the chart and keep a backup

Follow the numbered highlights below. On a phone, tap a step to zoom straight to that control, then swipe the enlarged screenshot to explore. These are screenshots; use the live tool to enter values.
  1. Choose the date, height and unit.Enter the date the measurement was taken, then its measured height. You can enter centimetres, metres, inches or decimal feet. For feet, 5.5 means 5 ft 6 in. A chart title is optional; the screenshots use Example height history.
  2. Select Add measurement.Add readings in any order. The chart and history table sort them by date. The tracker keeps one reading per date and supports up to 300 readings; use Edit for a correction instead of adding a duplicate.
  3. Read the chart and download its PNG.The summary shows the latest reading, the difference between the first and last readings, and elapsed days. Dates are spaced by time. Check the vertical axis: it zooms to your readings unless Start height axis at zero is selected. Download chart PNG creates a chart image on your device; the image includes your title and measurements.
  4. Choose whether to save on this browser.Saving is off by default. Enable the checkbox only if you want the history to remain after reloading this page. It uses this browser profile and is not cloud sync. To remove that saved copy, turn saving off; the current page history remains open. If another tab changes the saved copy, saving pauses instead of overwriting it. Export your current CSV before choosing Load saved history.
  5. Download a CSV backup.Expand CSV backup and import, then select Download CSV. A CSV is an editable backup of the dates and heights, while the PNG is a chart image. Keep separate CSV files for separate people.
  6. Restore or merge a CSV backup.Select Choose file under Import CSV backup and pick a file from your device. Use the columns date,height_cm; dates must use YYYY-MM-DD and heights must be in centimetres. A sample template is linked below the file picker. Imports merge new dates. Duplicate dates, invalid rows, a file above 50 KB or a combined history above 300 readings stop the entire import without changing existing readings.

Edit a date or height

Follow the numbered highlights below. On a phone, tap a step to zoom straight to that control, then swipe the enlarged screenshot to explore. These are screenshots; use the live tool to enter values.
  1. Select Edit beside the reading.The original date and height load into the form. The form heading changes to Edit measurement. If the controls are above the table on your phone, the tracker moves to them.
  2. Save the correction or cancel.Change the date or height and select Save measurement. Dates cannot conflict with another reading. Cancel edit leaves the existing reading untouched. A saved correction updates the chart and changes in the history table.

Remove a reading and undo it

Follow the numbered highlights below. On a phone, tap a step to zoom straight to that control, then swipe the enlarged screenshot to explore. These are screenshots; use the live tool to enter values.
  1. Use Undo last removal.Select Remove beside a reading, or Clear history below the table. Undo last removal then appears. Select it to restore the previous history. Undo is available until the next add, saved edit, import or page reload. Download a CSV backup before clearing a history you want to keep.

The screenshot shows one example reading removed: the chart and totals change, and Undo last removal appears next to Clear history.

Quick answers

Will reading this guide clear my current measurements?

The tool’s How to use link opens this guide in a new tab, keeping the tracker tab and its current readings open. Closing or reloading the tracker itself clears unsaved data; browser saving or a CSV backup can preserve it.

Why does my CSV import fail?

Check the two column names, date format, height values and duplicate dates. An import is rejected as a whole if any row fails, so your current history stays unchanged.

Does this log assess growth or predict future height?

No. It charts the measurements you enter. It does not calculate growth percentiles, assess typical growth or predict adult height.
