Scaled dimension
A 4.2 m vehicle at 1:35 is 120 mm long; the same vehicle in HO (1:87) is 48 mm, and in N gauge (1:148) just 28 mm.
How Scale Model Converter works
- Read the sample dimensions for a 4.2 m vehicle at 1:35, HO, and N scales.
- Explore the scale and direction selectors as preview controls; they do not calculate dimensions.
- For a manual conversion, use matching units and divide the real dimension by the scale denominator.
FAQ
Does changing the scale calculate a new model size?
No. The widget displays a fixed example. The scale and direction selectors are preview controls, and Convert only changes the status text.
Which scales appear in the selector?
The choices are 1:12, 1:24, 1:35, 1:72, 1:87 (HO), and 1:148 (N).
What size is the sample vehicle at 1:35?
The displayed example uses a 4.2 m vehicle. Converting to 4,200 mm and dividing by 35 gives 120 mm.
