Size Comparison — Height, Length and Width on One Scale
A size comparison engine for everything, not just people. Choose the dimension that matters — height, length or width — filter the library to objects that actually have that measurement, and plot them on one shared scale.
- 3 dimensions
- Sourced data
- One true scale
Outlines are illustrative silhouettes; every plotted value is a real measured figure on one shared true-to-scale axis.
Size comparison beyond heights
Heights are easy — everything stands upright. A real size comparison gets harder the moment objects differ in kind: a horse is tall at the shoulder but long from nose to tail, an SUV is short compared to a person yet massive in length, and an airliner dwarfs both in every direction. The only honest way through is to compare one dimension at a time, on one axis, with objects whose measurement basis is stated.
That is the discipline this size comparison tool enforces. Switch to Length and the library filters to objects with a published body length — an elephant at 6.5 m, an A380 at 72.6 m. Switch to Width and the same objects reappear as horizontal bars scaled to their real spans. The tool never silently substitutes a length where a height should be; each preset carries its measurement basis and source, and only compatible objects enter the running.
The result is a size comparison you can trust in a presentation or an argument: same pixels-per-centimeter for every bar and silhouette, ruler ticks that span the full canvas, and values you can cite because their sources are printed beneath the tool — few size comparer pages are this open about their numbers.
How to run a size comparison
Pick a dimension, pick your objects, done — the tool keeps the geometry honest while you focus on the question.
1Choose the dimension
Toggle Height, Length or Width above the canvas. The size comparison immediately re-plots every object using its real measurement for that dimension.
2Add objects from the library
Search people, animals, vehicles, buildings or everyday objects. Each chip shows the object’s value for the current dimension, so the size comparison preview starts before you even click.
3Compare, export, cite
Read the scaled chart, download PNG or SVG, and copy the source labels — every size comparison here is backed by checkable published measurements.
Why this size comparison stays honest
Dimension-aware library
Objects without a published length never appear in a length comparison. Filtering by real data availability is what separates a size comparison from a guess with pictures.
Basis labels, always visible
Shoulder height, total height, body length, wingspan — the tool prints each object’s measurement basis and source under the canvas, so your size comparison survives scrutiny. That is what makes this a size comparison tool you can cite.
Bars for widths, shapes for lengths
Width mode renders precise horizontal bars; length mode re-draws side-view silhouettes proportionally. Each dimension of the size comparison gets the visual form that reads best.
Sample objects with every dimension listed

| Object | Height | Length | Source basis |
|---|---|---|---|
| Domestic cat | 25 cm (shoulder) | 46 cm (body) | Published species data |
| Labrador retriever | 58 cm (shoulder) | 110 cm | Breed standard data |
| Horse | 160 cm (withers) | 240 cm | Published species data |
| African elephant | 320 cm (shoulder) | 650 cm | Published species data |
| Mid-size SUV | 180 cm | 480 cm | Class-typical figures |
| Double-decker bus | 440 cm | 1140 cm | Published vehicle data |
| Semi-truck | 400 cm | 1600 cm | Published vehicle data |
| Airbus A380 | 2419 cm (tail) | 7257 cm | Manufacturer data |
| 10-story building | 3000 cm | — | Story-height standard |
Height and length are different measurements and are never mixed on one axis; the tool switches between them rather than averaging them into a fake “size”.
The three dimensions, and when each matters
Height answers “how tall”: people, buildings, shoulder heights of animals. Length answers “how long”: vehicles, body lengths, aircraft fuselages. Width answers “how wide”: wingspans, goal mouths, vehicle beams. A meaningful size comparison picks the dimension that matches the question — comparing a snake to a person in height is meaningless, in length it is spectacular.
Watch for basis traps. A giraffe’s 5 m is total height; a horse’s 160 cm is withers (shoulder) height — its head towers well above that. Our labels keep these bases explicit so your size comparison never stacks an apple against an orange. When two objects share a dimension but not a basis, the note line tells you, and you can decide whether the pairing still makes your point.
size comparison — FAQ
Can a size comparison mix people and vehicles?
Yes — a person, a door, an SUV and a giraffe share one scale naturally. The size comparison keeps each object on its true value; nothing is enlarged or shrunk for composition.
Why did the library shrink when I switched to Length?
Because only objects with a published length are shown. Hiding objects without the data is deliberate: a size comparison is only as good as the weakest number in it.
What does Width mode show?
Horizontal bars scaled to real spans — an A380’s 79.9 m wingspan next to a soccer goal’s 7.32 m mouth. Bars keep a wide-span size comparison readable where silhouettes would collapse.
Are the numbers reliable?
Preset values are rounded figures from published sources — species accounts, manufacturer specs, sports standards — with the basis and source printed beneath the size comparison canvas.
Can I add my own object?
Yes. Add a custom object with any name, value and color; it plots on the same scale as every library preset, and a one-off size compare against a preset works exactly the same way.
