Use these tools to plan a model project and keep product details together. Calculations use the dimensions you enter; check the manufacturer’s specifications before choosing a part.
Scale and dimension converter
Convert a real-world dimension to a model dimension, or work back from a model. Use the scale stated by the manufacturer.
This calculation compares dimensions only. It does not establish track gauge, wheel fit, electrical compatibility or whether parts will fit together.
Before combining products
- Check the manufacturer's model and item numbers.
- Check scale, gauge, physical dimensions and connection type separately.
- Read the listed contents and identify any required accessories.
- Use the exact variant and the manufacturer's compatibility information.
Compatibility checklist
- Match the exact model or part number and the intended scale.
- For railways, check gauge, track system, couplers, minimum curve and control system separately. Matching scale alone does not guarantee a fit.
- For slot cars, check the track family, electrical system, chassis and connector standard.
- For wheels, tires and other parts, check the actual dimensions and mounting interface.
- For kits, confirm required tools, paint, adhesive, batteries or other supplies. Only treat an item as included when the source lists it.
