Comparison in Size: Explore 3–8 Objects
Put three to eight objects on one true scale and explore how they relate: sort from smallest to largest, drag your own arrangement, fix any object as the reference, and read each one as a multiple of it. This is comparison in size for whole groups, not just pairs.

Outlines are illustrative silhouettes; every plotted value is a real measured figure on one shared true-to-scale axis.
What is a comparison in size?
A comparison in size answers a different question than a two-object check: not "which of these two is bigger", but "how do all of these relate". Line up a man, a door and a giraffe on one axis and the group tells a story no pair can: the door clears the man by a head, the giraffe clears both by more than double. Exploring three to eight objects at once is how a comparison in size becomes intuition instead of arithmetic.
The scene opens with three verified objects — an average US man (175 cm), an interior door (200 cm) and a giraffe (500 cm) — all standing heights from published sources, with the man preselected as the reference. Every other value reads against him: the door at 1.14×, the giraffe at 2.85×, and the largest-to-smallest spread of the whole group prints underneath the table.
Nothing on the canvas is decorative. Every silhouette shares one pixels-per-centimeter factor, every plotted value is a published figure, and objects that cannot be measured in the active dimension are refused rather than guessed. A comparison in size you cannot check is a rumor — this one carries its sources.
How to run a comparison in size
The toolbar holds everything: add objects, switch dimension, sort, and the reference picker sits beside the result table. One minute covers the whole flow.
1Add up to eight objects
Tap Add object and search the library — people, animals, buildings, vehicles — filtered to objects carrying verified data in the active dimension. The button disables at eight with a clear limit message, because a comparison in size stays readable only while the group stays scannable — that limit is part of the design.
2Sort, or drag your own order
One tap sorts the group from smallest to largest or the reverse — sorting reorders the display only and never touches a measured value. Prefer your own narrative? Drag any row into position and the comparison in size follows your arrangement exactly.
3Pick the reference
Choose any object as the reference from the selector — or tap "ref" on its row. The table restates every other object as a multiple of it plus the signed gap; the drawing itself never changes, because the reference shapes the readout of this comparison in size, never the truth behind it.
4Switch dimension, share, export
Height, length and width buttons remap every compatible object to its published value and clear the rest with a notice, so the comparison in size never mixes dimensions in one scene. Reset, share a link that reproduces the scene, or export PNG/SVG.
What makes this comparison in size honest
A reference table, not just a picture
Beneath the canvas every object reads as a multiple of the reference plus its absolute gap, in a stable largest-to-smallest order with matching colors — the numbers and the drawing never disagree.
Sorting that never rewrites data
Sort buttons reorder rows and figures; the centimeter values behind them are untouchable from the toolbar. Your comparison in size stays sourced no matter how you arrange it.
Dimension gating with a reason
In a comparison in size, objects without published data for the current dimension are cleared on switch, with a notice saying why — the tool refuses to keep a value it cannot verify, which is what keeps every comparison in size produced here defensible.
Spread at a glance
Largest, smallest and the largest-to-smallest ratio print under the table: 500 versus 175 is a 2.85× group, the single number that summarizes the whole comparison in size at a glance.
Reproducible scenes
The share link encodes the whole group — objects, dimension, unit, reference — so your comparison in size opens identically on any machine, no account, no server state — the comparison in size travels in the link itself.

Six starting groups, each fully in the library — open the tool and rebuild any comparison in size in three clicks.
| Group | Objects (cm) | Largest | Smallest | Spread |
|---|---|---|---|---|
| Safari line-up | Giraffe 500 · Man 175 · Child 120 | Giraffe | Child | 4.17× |
| Street scene | Traffic light 450 · Door 200 · Man 175 | Traffic light | Man | 2.57× |
| Living room | Door 200 · Child 120 · Cat 25 | Door | Cat | 8.00× |
| Big predators | Polar bear 160 · Wolf 80 · Labrador 58 | Polar bear | Labrador | 2.76× |
| Basketball court | Hoop 305 · Player 199 · Teen 163 | Hoop | Teen | 1.87× |
| Skyline | Skyscraper 30000 · Tower 3000 · Oak 2000 | Skyscraper | Oak | 15.00× |
Spreads come from raw centimeter values on the height dimension — the same number the tool prints for any comparison in size you assemble.
Reference, spread, dimension: reading the group
The reference is the anchor of a group comparison in size. Multiples are honest only against a named baseline: a giraffe is 2.85× an average man but 2.50× a door — same giraffe, different anchor. Pick the reference your question is actually about, and read every other row as a multiple plus a signed gap.
The spread — largest divided by smallest — is the fastest summary of any comparison in size, but it hides the middle of the group. A 15× skyline spread and a 4× living room can both contain a near-tie; sort smallest to largest and the table exposes what the single ratio flattens. That is why this page prints the full table instead of one headline number — a comparison in size deserves the whole cast.
Keep one dimension per scene: that rule is the whole grammar of a comparison in size. Heights belong with heights, lengths with lengths; the moment a door height meets a truck length, the spread stops meaning anything. The dimension switch enforces this by clearing unmeasurable objects, so your comparison in size never silently mixes units of meaning.
comparison in size — FAQ
How do I build a comparison in size on this page?
The tool opens with three objects; tap Add object to search the library, sort or drag the rows into order, and pick a reference. Every object then reads as a multiple of the reference in the results table — a complete comparison in size in under a minute.
How many objects can one comparison in size hold?
Three to eight. Three is the primary experience, two is the minimum after removals, and eight is the cap — the Add button disables with a message at the limit so the scene stays readable.
What does the reference do?
It anchors the table: every other object is shown as a multiple of it plus the signed difference. Switching reference changes the readout only — the anchor of the comparison in size moves, the scene does not — the drawing and every measured value stay exactly as they were.
Does sorting change the plotted sizes?
No. Sorting reorders the display sequence; the centimeter values are published figures and cannot be rewritten from the toolbar. Only dragging changes the arrangement, and it moves rows, not numbers.
Why did an object disappear when I switched dimension?
Because it has no published data for that dimension — a giraffe has a verified height but no verified width. Rather than invent a number, the tool clears the object, tops the group back up, and tells you what happened to your comparison in size.
Can I share my comparison in size?
Yes — the Share button encodes the objects, dimension, unit and reference in the URL. Whoever opens it sees the identical scene; nothing is stored on a server.
