1:64 Scale Conversion
At 1:64 scale, every one unit on the model represents 64 of the same units in real life. For example, an object that is 64 cm long in the real world measures 1 cm on the model.
Use the calculator above to convert real size to 1:64 scale or convert 1:64 scale to real size. It works with millimetres (mm), centimetres (cm), metres and inches, and you can choose different input and result units. Choose millimetres when you need 1:64 scale in mm, or switch to cm or inches for the measurement you already have.
Example measurements for a 1:64 scene
These are example real-world dimensions, not required sizes for every scene. Measure the object you want to model, then divide that measurement by 64.
| Detail | Real size | Model size (1:64) |
|---|---|---|
| Person's height | 180 cm | 28.125 mm |
| Garage door height | 2 m | 31.25 mm |
| Parking bay width | 2.5 m | 39.0625 mm |
| Parking bay length | 5 m | 78.125 mm |
| Sign width | 64 cm | 10 mm |
| 64-inch object | 64 in | 1 in (25.4 mm) |
The calculation works in either direction: a 10 mm detail on a 1:64 model represents 640 mm in real life. A model that measures 7 cm represents 448 cm (4.48 m).
Use the measurements in a diorama
For a garage, measure the real door or wall graphic you want to reproduce and use its model width to plan the scene. For a parking area, calculate the bay width and length separately before drawing the ground layout. A 2.5 m by 5 m example bay becomes 39.0625 mm by 78.125 mm at 1:64. Check that your particular diecast vehicle fits your chosen bay before printing.
For a flat sign or poster, take its calculated width to the 1:64 print maker. Upload your image, enter its real-world width and export an A4 or US Letter PDF. You can also browse ready-made garage signs and parking signs. Print at 100% / Actual Size and measure the 20 mm calibration square. The current generators arrange selected graphics on a print sheet; measure any ground layout separately.
FAQ
What is 1:64 scale in cm?
At 1:64 scale, 1 cm on the model represents 64 cm in real life. To convert a real measurement in centimetres to its 1:64 size, divide it by 64.
What is 1:64 scale in inches?
At 1:64 scale, 1 inch on the model represents 64 inches in real life. One real-world foot becomes 3/16 inch (0.1875 in) on the model.
How do I convert a real size to 1:64 scale?
Use the formula real size ÷ 64 = scale size. For example, 448 cm ÷ 64 = 7 cm.
How do I convert a 1:64 scale measurement to real size?
Use the formula scale size × 64 = real size. For example, 7 cm × 64 = 448 cm.
Why does my printed item come out the wrong size?
The calculation may be correct while the printer is still resizing the page. Use Actual Size / 100% and disable Fit to Page or similar options.
