YOUR COMPARISON
The height canvas
Your perspective starts here
Enter a name, age and height to build your own comparison.
Illustrative age-based visuals. Figure heights follow the measurements you enter; body shapes are generic outlines, not measurements of any real body.
Difference between two entries
Growth snapshots
Entries sharing a name, ordered by age. Change is measured against the previous entry you typed in.
| Person | Age | Height | Weight | Change in height |

What this tool does.
And where it stops.
Turn measurements you already have into a comparison you can see. Here’s what you can create with your numbers.
Compare on one scale
See up to 40 people or snapshots, aligned at the same baseline.
Read the exact gap
Select two entries for their height difference and percentage difference.
Revisit growth
Reuse a name at different ages to see changes between recorded measurements.
Switch your units
Use centimetres or feet and inches, with optional weight in kg or lb.
Make it personal
Choose figure colours, an age-based silhouette and an optional head photo.
Take the chart with you
Download a PNG or JPG. Entered measurements are saved in this browser; photos stay in the tab.
Clear limits make the comparison more useful.
No height prediction
It doesn’t forecast adult height, estimate missing years or fill gaps in your growth records.
No health assessment
It doesn’t calculate growth percentiles, diagnose conditions or decide whether a height is healthy.
No photo measurement
It doesn’t measure height from an image, scan your body or use weight to recreate body shape.
Your measurements set the result. For a useful comparison, enter heights measured using the same method.
How the figures are drawn
Three inputs shape each figure. Knowing which does what makes the comparison easier to read.
Height sets the size
Figure height is entered height divided by the current top of the scale. Nothing is nudged for looks, so a 180 cm figure is exactly 20 percent taller on screen than a 150 cm one.
Age sets the proportions
Head-to-body ratio, limb thickness and leg length shift continuously with age — roughly one head in four at age two, one in seven by adulthood. A 13-year-old and a 17-year-old are drawn differently.
Person type sets the build
Shoulder, waist and hip widths and the hair outline differ across boy, girl, man and woman. The shapes stay plain silhouettes; nothing beyond build is implied.
Pick the right setup
| What you want to do | Use this setting | What you get |
|---|---|---|
| Compare two people | Add two entries with heights | Both figures on one scale plus the exact gap |
| Show growth over time | Add the same name at different ages | Age-by-age snapshots and a change column |
| Compare a whole family | Add each person as a separate entry | One row of figures, sortable tallest to shortest |
| Tell people apart at a glance | Give each entry its own colour | Colour-coded figures and list rows |
| Use a real face | Upload a photo on the entry | The photo fills the figure's head, export included |
| Compare young children | Set age below 13 and pick boy or girl | Child proportions instead of adult ones |
| Work in imperial units | Switch height to ft/in and weight to lb | Converted values everywhere, export included |
How to use it
Pick the person type
Boy, girl, man or woman decides the silhouette. The age you enter fine-tunes it.
Enter the measurements
Name, age and height are required. Weight, colour and photo are optional.
Add more entries
Another person, or the same name at a different age. Both belong in the same comparison.
Read it, then export
Check the gap between any two entries, then save as PNG or JPG.
Track growth across ages
Most height comparisons assume every entry is a different person. This one doesn't. Enter one name several times with different ages, and those entries are grouped into a chronological set of snapshots with the height change between each one.
The tool only repeats what you typed. It does not estimate a missing year, project an adult height, or compare anyone against a growth chart or percentile. If you want a gap filled, measure it and enter it.

Height comparison FAQs
How does this height comparison tool work?
Enter each person’s name, age and height. The height comparison chart draws the entries on one shared scale, and you can select two entries to calculate their height difference.
Is this height comparison tool free?
Yes. You can compare heights, add recorded growth snapshots and export a PNG or JPG chart without creating an account.
Can I compare more than two people?
Yes. Add up to 40 people or growth snapshots; they all share one scale.
Can I use the same name more than once?
Yes, and it is deliberate. Repeated names at different ages are grouped into growth snapshots.
Do the four person types look different?
Yes. Shoulder, waist and hip widths, limb thickness and the hair outline all differ, and age adjusts the proportions inside each type.
Do I have to upload a photo?
No. Without one, the tool draws the illustrated head that matches the age and person type.
Where do my photos go?
Nowhere. They are read by your browser with FileReader and drawn locally. No request is made to any server, and photos are never written to local storage.
Can I mix children and adults in one comparison?
Yes. The scale adapts to the tallest entry so both stay readable.
Is weight required?
No. If entered, it is shown as entered and converted between kg and lb. The tool draws no health conclusion from it.
Does this predict how tall someone will be?
No. It displays measurements you entered and the differences between them.
Can I work in feet and inches?
Yes. Switch the height unit at any time; every label shows both units and entry switches to separate feet and inches fields.
Does it work offline?
Once the page has loaded, yes. The tool makes no network calls and loads no external libraries.
