Scale converter
Miniature Scale Converter
Pick a scale, put in a real-world height, and see what that subject measures in every other scale — or flip it around and put in the millimetres you just measured on a model to find out how tall the thing it stands for really is. The table redraws as you type.
- 28 mm heroic, 32 mm, 15 mm, 1/56, 1/72 and more, in one table
- Your own scale, typed in as millimetres or as a ratio
- Runs entirely in your browser — nothing you type is uploaded or saved
Every scale, side by side
The bars are drawn to the same scale as each other, so the longest bar is the biggest model. "vs your scale" tells you how much taller or shorter the same subject is in that scale: ×2.00 means twice the height of your pick, ×0.50 means half of it.

Long-time tabletop painters will notice that 28 mm heroic lands near 1:65 and 32 mm heroic near 1:57, while 1/56 and 1/72 are honest ratios. That gap is the whole reason this page exists: a label on a box and a ratio on a kit box are two different promises, and the table shows both.
How to use it
- Pick the scale you are working in. If it is not in the list, choose "Your own scale…" and type it in as either a figure height in millimetres or a ratio like 1:56.
- Say what you know. Real height going down to model size, or a measured model going back up to real size — the switch at the top of the panel changes which number the maths starts from.
- Add your own scale side by side. With a custom scale picked, it appears as the first row of the table, so you can compare it against every built-in scale instead of guessing.
- Watch the numbers while you type. The table and the bars update on every keystroke, so it is easy to nudge a height until a model lands on a round number.
- Copy the table if you need it later. The copy button gives you the whole thing as plain text — handy next to a shopping list or in a project note.
What this converter does not do
- It does not know your model. It converts the number you type, which is why a height you measured yourself always beats the label on the box.
- It does not model heroic proportions. A 28 mm heroic figure has an oversized head and hands, so it looks right next to a true 1:65 figure only until you compare them side by side.
- It does not include every scale ever made. It carries the common millimetre figure scales and the common kit ratios, and the custom option covers anything else.
- It does not measure in millimetres, feet or anything else. The number is yours; the arithmetic is the reference behind every millimetre scale name, which is a 6 ft (1.83 m) human, or 1,828.8 mm.
- It does not store, send or remember anything. Reload the page and it is back to the defaults.
Questions I get about miniature scales
What does 28mm heroic actually mean?
It means a six-foot human is 28 mm tall in that range, and that the figure is deliberately out of proportion on top of it — bigger head, bigger hands, chunkier weapons than a true 1:65 human would have. That is why 28 mm heroic and 1/56 are not the same thing even though people use them together: 1/56 is honest 1:56, while 28 mm heroic is 1:65 with exaggeration built in. The converter above does the arithmetic on both and never pretends the exaggeration is not there.
How do I convert 28mm to 32mm scale?
Divide one by the other: 32 divided by 28 is 1.14, so the same character is about 14% taller in 32 mm scale. A 28 mm figure standing 28 mm tall becomes roughly 32 mm, and a 40 mm monster in 28 mm scale becomes about 46 mm in 32 mm. Enter your own model height above and the table gives you the exact number for every scale in the list, not just the two you asked about.
What scale is 1/56 in millimetres?
1/56 puts a six-foot human at about 32.7 mm, which is why 1/56 vehicle kits are sold alongside 28–32 mm figures for games like Bolt Action. In the table above, the 1/56 row and the 32 mm heroic row land within a millimetre of each other — close enough to share a table, not close enough to mix within one unit.
How tall is a 28mm miniature in real life?
A 28 mm figure represents a roughly six-foot person, because the scale is defined that way. If you have measured your own model instead, switch the converter to "I measured my model", put in the millimetres, and it will tell you the real-world height it stands for — a 45 mm model in 28 mm scale is a nine-and-a-half-foot monster, not a person.
Are 1/72 and 20mm the same scale?
Close, but not identical. 1/72 puts a six-foot human at about 25.4 mm, so it sits between the 20 mm and 25 mm rows in the table, and the difference is small enough that plenty of ranges are sold as both. If you are matching vehicles to figures, convert the actual height you care about rather than trusting the label on the box — that is exactly what the table is for.
Does this converter work for vehicles and buildings too?
Yes. The maths is a straight ratio, so it does not care whether the subject is a person, a tank or a tower — enter the real height in feet, inches, metres or centimetres and every scale gets a model size. The only place the six-foot human matters is the label on millimetre scales, and the page says so rather than hiding it.
