Single DIN vs. Double DIN: What’s the Difference?

Are you finally pulling the plug on an outdated radio and buying a new one? Perhaps you’re simply upgrading for the fun of it. Either way, you’ve got plenty of options to choose from. The market’s overflowing with all kinds of stereos, so why not narrow down your options by learning about single DIN stereos versus double DIN units? 

What Does DIN Size Mean?

To understand the differences between single DIN and double DIN radios, we should first define what DIN size actually means. 

In German, DIN stands for “Deutsches Institut für Normung,” which translates to the German Institute of Standardization. As their name suggests, this organization is in charge of standardizing thousands of measurements used in various fields, including the automotive industry. 

DIN size refers to the standardized size of a car stereo’s chassis. Because there’s a standard size for car stereos, it’s a lot easier for consumers to find the right one for their vehicles. 

What Is a Single DIN Radio? 

A single DIN radio is one of the two common DIN sizes you’ll find on the market. It’s two inches tall and seven inches wide. 

What Is a Double DIN Radio? 

Similar to a single DIN car stereo, a double DIN radio is seven inches wide, but twice as tall as a single DIN radio at four inches tall. 

Double DIN vs. Single DIN: Their Differences

With the basic definitions out of the way, it’s time to dive into the differences between single DIN and double DIN radios. Here are some common characteristics that set them apart: 

Size

The most glaring difference between the two is their size. With a height of four inches, double DIN stereos are much taller than single DIN ones. 

This means they also tend to have larger display screens. In most cases, single DIN stereos come with small digital screens around one to three inches tall, while double DIN stereos typically come with six-inch touchscreens. 

Features

Because they come with touchscreens, Double DIN car stereos typically also come with extra features, such as rearview cameras, onscreen Global Positioning System (GPS) navigation, Apple CarPlay, and Android Auto. 

Unfortunately, you can’t expect the same from single DIN units. Most don’t come with a touchscreen, which rules out the possibility of adding these extra features.

Sound Quality

If you’re a big music lover, you’re better off with a vehicle that’s compatible with double DIN stereos. They typically come with more advanced audio processing features that you won’t find on most single DIN stereos. 

Usability

When it comes to usability, the single DIN stereo wins, but not by a wide margin. Single DIN units are relatively easy to install by yourself while installing a double DIN stereo might require a professional. 

Double DIN radios also come with more features, which means there’s a bigger learning curve for drivers who might not be tech-savvy. On the other hand, single DIN radios have straightforward controls, but their smaller size can make it harder to see. 

What to Look for When Buying a Car Stereo

Are you thinking about buying a new stereo for your car? Here are some factors to consider before you make your choice: 

Audio Sources

Whether you’re going for a single DIN or double DIN stereo, be sure to check what audio sources it’s compatible with. While most single DIN units only offer basic features such as AM/FM radio and CD players, some also come with Bluetooth connectivity and auxiliary input jacks. 

Smartphone Integration

Do you often use apps like Apple CarPlay and Android Auto? If you do, then you might want to consider getting a double DIN radio instead. Most single DIN stereos don’t come with smartphone integration, while double DIN units are much more versatile and can connect to your smartphone easily. 

Cost

If you’re on a tight budget, then a single DIN stereo is likely the best choice for you. They cost less than most double DIN units. They’re also easier to install, so you can save on professional fees by installing one yourself. 

What DIN Size Is My Car?

Sometimes, just one look at your console can tell you what DIN size your car is. If your stereo control panel is only around two inches tall, then you likely have a single DIN slot. 

If you aren’t too sure, you can always use a lookup tool online. You just have to input your vehicle’s year, make, and model, and then the tool lets you know if your vehicle can fit a single DIN stereo, double DIN unit, or both. 

Single DIN vs. Double DIN: Which One’s Better?

If you’re looking for an objective answer to that, you won’t have much luck. Single DIN and double DIN stereos both come with their fair share of advantages and disadvantages, so it all depends on what you’re looking for. 

Can You Fit a Single DIN in a Double DIN Slot? 

Yes, you can fit a single DIN unit in a double DIN slot, but you’ll need a mounting bracket to fill up all that extra space on your console. Mounting brackets typically cost around $10, and they should come with a manual that provides a step-by-step guide on how to use the bracket to install your new radio.
