RC cars remain very popular today as both hobby-grade vehicles and advanced racing machines organized into official circuits. Their customization and ability to race head-to-head provide an exciting creative outlet and competition for enthusiasts.

What Does 1/12 Scale Mean?

Now let’s look at what the 1/12 scale signifies specifically.

Explanation of Scales

The scale of an RC car refers to how the size compares to a real full-size car. For example, a 1/10 scale means that the RC car is one-tenth the size of the actual car. The larger the denominator, the smaller the RC vehicle.

1/12 Scale Dimensions

A 1/12 scale RC car is defined as one-twelfth the size of a real car. For dimensions, this translates to a length of approximately 14-15 inches and a height of around 4 inches. Wheels have a diameter of 2.2 inches typically.

So in summary, a 1/12 scale RC car is a miniature vehicle around 15 inches long and 4 inches high. This provides a great balance of size to incorporate realistic details while still being small enough to handle well.
