Model Train Scales

 

If you’re new to the world of model railroading, one of the first questions you’ll encounter is: Which scale should I choose? Whether you’re designing a layout for a small shelf or an entire room, understanding model train scales is essential.

 

This guide breaks down the most popular model train scales—especially HO and N scale—and helps you decide which one fits your space, goals, and budget.

 

 What Is a Model Train Scale?

A model train scale refers to the ratio between the size of your model train and its real-world counterpart. The scale determines everything—from the size of locomotives and tracks to the buildings, figures, and model railway farm animals that surround them.

 

For example:

  • A 1:87 scale means the model is 87 times smaller than the actual train. 
  • The larger the number, the smaller the model. 

The scale you choose will affect:

  • How much space your layout needs 
  • The level of detail visible 
  • The cost of trains, scenery, and accessories 
  • Compatibility with model railway supplies and railway accessories online 

Common Model Train Scales

 

Let’s explore the most popular model train scales:

 

1. HO Scale (1:87)

  • Easy to work with due to larger size compared to N scale 

HO Scale Pros:

2. N Scale (1:160)

3. Other Scales (Brief Overview)

While HO and N are the most common, others include:

  • O Scale (1:48) – Large and highly detailed, needs lots of space 
  • Z Scale (1:220) – Ultra-small, for compact and portable layouts 
  • G Scale (1:22.5) – Garden railways and outdoor use 

If you’re just starting out, stick to HO or N for best variety and support from online retailers like eTrains.

 How to Choose the Right Scale

Ask yourself:

  • How much space do I have?
     N scale if limited, HO if you can spare a table or board. 
  • Do I value detail or layout complexity?
     HO for visual realism, N for expansive scenes. 
  • Do I want easier handling?
     HO is better for younger or less dexterous users. 
  • What does eTrains recommend?
     For beginners, HO is often the easiest starting point thanks to the huge product variety and ease of building scenery like model railway farm scenes and stations with LED lighting. 

 Final Thoughts

Choosing the right model train scale is a big step—but it doesn’t have to be overwhelming. If you want a balance of detail and ease, go with HO scale. If you’re short on space but want a big layout, N scale is your best bet.
