Which Model Train Gauge is Right for Me?

If you have just gotten started with a new hobby in the area of model trains, you probably noticed that there are a number of different sizes (or gauges) to choose from when purchasing the various train cars.

It can sometimes be a bit confusing to try to figure out what all the different numbers and ratios mean. Essentially, if you see a ratio like 1:87, what it means is that a life-sized train is 87 times larger than the model train. Understanding gauge is very important in the model train hobby because it helps the hobbyist ensure that all of their model trains are uniform in size and are compatible with the type of track they choose to use. It will also give you an idea of what size train pieces you will want to use depending on the amount of space you have to work in.

Below you will find the six available gauges explained by size and application so that you can make more informed decisions about your new model train hobby.

Starting with the largest gauge is the G gauge which has a ratio of 1:22.5 (a real train car is 22 and a half times larger than this model). Many people use this large scale model to create an outdoor train setup, because it becomes an integral part of the landscaping in a yard or garden setting. There are many companies that specialize in this gauge, including Aristo-Craft and Bachmann.

The next smaller gauge is the 1:48 O gauge model train (a normal train is 48 times larger). This size is great for kids because it is the perfect size for holding and moving around, and would make a great gift for any child. If you are looking for O gauge trains, Lionel has this gauge covered.

With a 1:64 ratio, the S gauge train is smaller still. This is a great size for hobbyists who have the space for an intricate full set.

The best known and used gauge is the HO at 1:87. Because it is so popular with model train hobbyists, there are infinite possibilities with this scale. It is the mid-range, and most model train retailers have hoardes of supplies to accomodate it.

N gauge trains are very popular as well, and are half the size of the HO gauge at 1:160. Because of their small size, the sets are customizable to fit into a small space.

Last but not least, the Z gauge at 1:220 is the smallest of them all, and the detail was not spared when making these miniscule trains. If you have only a small space to work in but still want to have a long train, this is the perfect gauge for you.
