How miniature scale conversion works

For 1:12 scale, divide the real-world measurement by 12. For 1:24, divide by 24; for 1:6, divide by 6; and for 1:48, divide by 48. This calculator converts inches, centimeters or millimeters into the miniature measurement.

Example

A real 120 mm object becomes 10 mm at 1:12 scale and 5 mm at 1:24 scale.

Check a conversion before you build

  2. Choose inches, centimeters or millimeters.
  3. Select 1:6, 1:12, 1:24 or 1:48 scale.
  4. Read the calculated miniature measurement and use it when sizing or checking your project.

Miniature scale calculator FAQ

What does 1:12 scale mean?

At 1:12 scale, one unit on the miniature represents twelve of the same units on the real object. A 12-inch real-world measurement therefore becomes 1 inch in miniature.

Can I calculate 1:6, 1:12, 1:24 and 1:48?

Yes. Choose the scale in the calculator and Piccolune divides the real-world measurement by 6, 12, 24 or 48 as appropriate.

Why should I check the printed reference line?

Browser zoom does not determine printed size. If you print the scale-check page, choose 100% or Actual Size and measure the 1-inch reference line. A correct reference line confirms that the print dialog has not resized the page.

Can I use inches, centimeters or millimeters?

Yes. Use the unit that matches your source measurement; the calculator keeps the conversion within that measurement system.
