Understanding RC Car Scales and Sizes

Remote control (RC) cars are a fun and exciting hobby that people of all ages can enjoy. But one of the first questions newcomers run into is a simple one: what do all these numbers actually mean? 1:10, 1:8, 1:5 — RC car scales can feel confusing at first glance. To help you figure out where to start with your new hobby, we've put together a comprehensive guide to understanding all RC car scales and sizes, from the pros and cons of each scale to how to choose the one that's right for you.

What Are RC Car Scales?

RC car scales describe how large your RC car is compared to the real vehicle it's modeled after. A scale of 1:10 means the RC car is one-tenth the size of the full-size original. A 1:5 scale car is one-fifth the size — which is why 1:5 scale RC cars are noticeably large. The smaller the second number, the bigger the RC car. So a 1:5 is larger than a 1:8, which is larger than a 1:10, and so on. The most common RC car scales you'll encounter are 1:5, 1:7, 1:8, 1:10, 1:18, and 1:24. Here's what each one means in practice.

Pros and Cons of Different RC Car Scales

Depending on how you plan to use your RC car and which driving experience you're after, certain scales will suit you better than others. Here's a breakdown of every common scale.

How Big Is a 1/5 Scale RC Car?

At 1:5 scale, you're working with one of the largest RC cars available — typically around 800mm (roughly 31 inches) long. These are serious machines designed for outdoor running in open spaces, and they turn heads wherever you bring them.

Some notable pros of 1:5 scale RC cars include:

• Huge presence and incredible visual impact on any terrain
• Built for serious outdoor running on dirt, gravel, and grass
• Compatible with a wide range of large-format 1:5 body shells for customization

A few cons to keep in mind:

• More expensive than smaller-scale options, both to buy and to maintain
• Requires ample outdoor space — not suitable for small yards or indoor use
• Parts and bodies can be harder to source than 1:10 or 1:8

How Big Is a 1/7 Scale RC Car?

The 1:7 scale has grown in popularity thanks to platforms like the Arrma Limitless, Infraction, and Felony — high-speed, street-style RC cars built for impressive top speeds. A 1:7 scale car sits between 1:5 and 1:8 in size, typically around 680–720mm long, and is ideal for open-space speed runs.

Notable pros of 1:7 scale include:

• High-speed focused — platforms like the Arrma Limitless are engineered for performance speed runs
• Sleek, aerodynamic body styles available from brands like Delta Plastik and JConcepts
• Strong aftermarket 1:7 scale body shell selection with performance-tuned designs

A few things to consider:

• Platform choice is narrower than 1:8 or 1:10 — fewer models to choose from
• High-speed running requires large, open spaces and careful setup
• Not as beginner-friendly as 1:10; better suited to hobbyists with some experience

How Big Is a 1/8 Scale RC Car?

A 1:8 scale RC car is one of the most popular and versatile sizes available for both newcomers and experienced hobbyists. At roughly 500–530mm long, it's large enough to be fast and exciting while remaining manageable for most outdoor spaces. Our expansive line of 1:8 RC cars covers both on-road and off-road applications.

Notable pros of 1:8 scale include:

• Available in electric and nitro configurations — huge variety of models and styles
• Works well for both on-road and off-road use
• Excellent selection of 1:8 buggy body shells, parts, and upgrade options
• Popular scale for club racing with an active community

A couple of cons to consider:

• More expensive than 1:10 to buy and maintain
• Nitro 1:8 models require more technical knowledge to run and tune

A popular example is our HB Racing Off-Road 1:8 lineup — a top choice for serious off-road racing.

How Big Is a 1/10 Scale RC Car?

The 1:10 scale is the most common RC car size and an excellent starting point for most newcomers. At roughly 400–450mm long, it's versatile enough for both indoor and outdoor use and supported by the widest range of models, brands, and accessories available. Because of how common the 1:10 scale is, there are numerous models to choose from, covering everything from crawlers to RTRs for off- and on-road racing.

Notable pros of 1:10 scale include:

• Enormous variety — crawlers, buggies, short course trucks, touring cars, and more
• The most affordable entry point for a quality RC vehicle
• Parts, body shells, and upgrade components are widely available
• Suitable for both indoor and outdoor use depending on the model

A couple of cons to consider:

• Not the fastest scale available — if top speed is the priority, 1:8 or 1:7 may suit you better
• Smaller size can feel limiting for experienced drivers compared to larger formats

A popular example of a great 1:10 model is the Xray XB4D 2023 Dirt Edition 1/10 4WD Electric Buggy Kit.

How Big Is a 1/18 Scale RC Car?

A 1:18 scale RC car is a compact option — typically around 280mm long — that falls between the micro world of 1:24 and the more mainstream 1:10. It's a great fit for people who want an RC car that's manageable indoors but still capable of outdoor fun. These are also considered miniature models and include mini rock crawlers for those not interested in a 1:24.

Notable pros of 1:18 scale include:

• Compact enough for indoor use in most spaces
• Available in crawler formats for technical trail driving
• More affordable than larger scales

A couple of cons to consider:

• Depending on the model, may not reach the speeds or handle the terrain types you're hoping for
• Fewer model choices and harder-to-find spare parts compared to 1:10 and 1:8

A great example is the Axial 1/18 UTB18 Capra 4WD Unlimited Trail Buggy RTR, available in numerous colors to suit your style.

How Big Is a 1/24 Scale RC Car?

At 1:24 scale, you're working with a micro-format RC car — roughly 175–190mm long — designed primarily for indoor crawling and precision driving. A 1:24 model is for a specific and niche section of hobbyists, but these cars can still offer a blast for people looking to start small.

Notable pros of 1:24 scale include:

• Perfect for indoor rock crawling on tabletop or small course setups
• Very compact and portable — easy to take anywhere
• A fun, affordable option for tight indoor environments

A couple of cons to consider:

• Not suitable for outdoor environments, bashing, or high-speed use
• Fewer upgrade options than larger scales

One notable example is the Axial 1/24 AX24 XC-1 4WS Crawler Brushed RTR — a capable micro crawler built for small-scale technical driving.

How to Choose the Right Size RC Car

Choosing the right RC car is a big decision, especially for beginners looking to have a fun and stress-free experience. Here are the key factors to weigh before making your purchase:

• Budget. Typically, the bigger the car, the higher the price — both upfront and in maintenance. If you're buying on a tighter budget, start with a 1:10 or 1:18 scale model.
• Environment. Large-scale models like 1:5 and 1:7 need open outdoor spaces. A 1:10 works well in most outdoor environments and some indoor ones. A 1:18 or 1:24 is best for indoor or small-yard use.
• Skill level. Larger and faster cars are harder to control at first. Most newcomers do best starting at 1:10 — it's manageable, parts are widely available, and the learning curve is gentle. Once you're comfortable, stepping up to 1:8 or beyond is very rewarding.
• What you want to do. Racing? Go 1:8 or 1:10. High-speed runs? Consider 1:7. Rock crawling? Look at 1:10, 1:18, or 1:24. Large-scale outdoor bashing? 1:5 or 1:8.

Tips for Getting the Most Out of Your RC Car

Once you've purchased your first RC car, you'll want to jump in and use it immediately. Consider these vital tips to get the most out of your newest RC car.

Maintenance and Care Tips

• Regularly tighten the car's screws, but avoid over-tightening.
• Don't use the car if you notice damaged parts, no matter how minor they might seem.
• Thoroughly check your RC car monthly — including the fluid within the shocks, and cleaning your driveshafts.

Driving Tips and Techniques

• Take your time getting used to the controls and mechanics of your RC car before pushing its limits.
• Don't drive in areas where your car isn't suited. Avoid driving small-scale models on rugged outdoor terrain, as this can cause significant damage.
• Purchase the car based on the terrain and driving style you want. Off-road and on-road vehicles are not built for the same environment.
• Know how a vehicle's power source will impact your experience. Electric vehicles run on batteries and often have higher speed capability, while nitro-powered RC cars provide a more realistic mechanical feel and advanced power output.
• Modify your vehicle if you feel you aren't getting the right experience — upgrades are a big part of the hobby.

Customizing and Upgrading Your Car

There are plenty of options for individuals who want to take their RC experience to the next level. Some popular upgrades available at AbsoluteHobbyz include:

• Upgrade your shock caps and shock fluid for better handling
• Replace your control arms for improved durability
• Try out new body shells for a fresh look or better aerodynamics
• Experiment with new tires for different terrains
• Upgrade your battery power for longer run times
• Replace your transmitter for more precise control
