HO vs 1/32 Slot Cars: Which is Right For You?

Slot cars have captured the hearts and minds of enthusiasts for decades, offering an exhilarating blend of speed, skill, and collectability. Over the years, manufacturers have produced slot cars and tracks in a variety of different scales, including 1:24, 1:43, 1:50, 1:76, and 1:87.

Fortunately, the slot car scene has settled down a bit in recent years, with most manufacturers sticking to one of two popular slot car sizes: HO (or 1/64 scale) and 1/32 scale. While both sizes offer their unique charms, understanding their differences is crucial to finding the perfect fit for your preferences.


In the early 1900s, HO Scale slot cars ranged in scale from 1:76 to 1:87. Today, HO slot cars tend to be a uniform 1:64 scale. That means it represents a proportional reduction of the real vehicle’s size by a factor of 64. In other words, 1 unit of measurement on a 1/64 scale model represents 64 units of measurement in real life.

HO scale slot cars are generally 2 ½ to 3 ½ inches in length, but all of them run along slot car tracks of roughly the same width.

Why is it called “HO Scale”?

Back in the early days of model trains and cars, the smallest scale size was a 0 (that’s a zero—not the letter “O”). When European manufacturers began producing smaller models, they didn’t want to start using negative numbers, so instead they dubbed the new scale “Half 0,” or H0 for short.

As you can probably guess, as time went on, the 0 got more and more confused with an O, particularly as slot cars picked up in popularity in the United States. Thus, they are now commonly known as HO scale.


The 1/32 scale is another commonly used ratio in the world of model vehicles, particularly slot cars. As we explained above, these vehicles are 32 times smaller than their real-life counterparts. 1/32 scale is one of the largest sizes of slot cars in current production, being exactly twice the size of their HO (1:64) brethren.

1/32 slot cars typically range from around 4 to 5 inches in length, providing a much more substantial presence on the track than HO models.

1. Price

Affordability is a big factor for many enthusiasts. HO slot cars, being smaller in scale, tend to be more budget-friendly compared to their 1/32 counterparts. The reduced size translates to lower production costs, resulting in more economical options for beginners or those on a tighter budget. HO slot car sets often offer great value for money, with starter kits that include everything you need to get started without breaking the bank.

On the other hand, 1/32 slot cars typically have a higher price range. These larger-scale models often boast more intricate details and higher-quality components, contributing to their increased cost. While the initial investment for 1/32 slot car sets may be higher, the enhanced realism and quality of the vehicles can be a compelling draw for those seeking a more immersive racing experience.

2. Selection

When it comes to selection, both HO and 1/32 scale slot cars offer a wide range of options to cater to different tastes and preferences. From classic muscle cars to modern sports cars and everything in between, you can find a diverse array of HO slot cars to suit your racing fantasies. Additionally, HO scale benefits from its popularity and widespread adoption, meaning that you can easily find HO tracks and vehicles at reasonable prices.

While not as extensive as HO, the 1/32 scale slot car market has grown significantly in recent years, offering an expanding selection of cars from various eras and genres. This scale particularly shines in its representation of highly detailed and accurate replicas, making it a favorite among collectors and enthusiasts with a penchant for realism. Additionally, the 1/32 scale tracks allow for more intricate circuit designs and scenery, further enhancing the overall racing experience.

3. Level of detail

When it comes to capturing the intricate details of real-life cars, the 1/32 scale reigns supreme. These larger models offer a greater surface area for manufacturers to showcase meticulous details such as accurate paint schemes, realistic interiors, and even working lights. The level of craftsmanship in 1/32 slot cars can be truly impressive, making them a delight for collectors and those who appreciate the artistry of scale modeling.

While not as highly detailed as their 1/32 counterparts, HO slot cars still exhibit a commendable level of detail, considering their smaller scale. They often feature vibrant paint jobs, modest interior detailing, and functional components such as headlights and taillights. HO slot cars strike a balance between affordability and visual appeal, making them an excellent choice for casual racers or those seeking a balance between performance and aesthetics.

4. Customizability

One of the joys of slot car racing is the ability to customize and personalize your tracks and vehicles. HO scale slot cars excel in this aspect, offering a plethora of aftermarket HO parts and accessories. From upgraded motors and chassis components to different tire compounds and gear ratios, the customization possibilities for HO slot cars are vast. This flexibility allows racers to fine-tune their cars to their preferred handling characteristics and performance levels.

In comparison, while not as extensive as HO, 1/32 slot cars still offer some degree of customization. Upgrades such as better motors, adjustable suspension systems, and different tire options are available for those seeking to enhance their performance on the track. However, due to their size and fewer available options, 1/32 scale parts and accessories are relatively more limited.

5. Performance

When it comes to performance, the size difference between HO and 1/32 slot cars plays a significant role. HO slot cars, being smaller and lighter, tend to offer nimble handling and quicker acceleration. The smaller size allows for tighter turns and more intricate track layouts, making HO racing ideal for those who enjoy technical driving and close-quarters racing. Additionally, the smaller scale often translates to higher speed potential, as the reduced weight can lead to faster lap times on shorter tracks.

Conversely, 1/32 scale slot cars provide a more substantial presence on the track. The larger size and weight contribute to a smoother, more stable ride, making them better suited for high-speed racing on longer straightaways. The increased heft can provide a sense of realism and stability, while the larger dimensions make it easier to appreciate the details and craftsmanship of the models.
