How do I know if a double DIN will fit my car?
What is a Double DIN?
A double DIN refers to the standardized dimensions for in-dash car audio receivers and head units. DIN stands for Deutsches Institut für Normung – the German national standards body that established DIN car stereo sizes in the 1980s. The single DIN size measures roughly 2″ high by 7″ wide, while the double DIN size measures roughly 4″ high by 7″ wide. The double DIN is twice the height of the single DIN, allowing for more space for larger screens, controls, and features. The double DIN dimensions according to the DIN 75490 standard are 180 mm (7.1 inches) wide by 100 mm (4 inches) high.
Most modern in-dash receivers are double DIN, taking advantage of the extra size to incorporate touchscreens, mobile integration, navigation and more. Double DIN head units protrude further out from the dash but allow for a much more feature-packed upgrade.
According to https://stereoauthority.com/single-din-vs-double-din/, “With double DIN stereos, you get a bigger display and more functions.” Upgrading to double DIN enables more advanced entertainment and convenience in your vehicle.
Why Upgrade to Double DIN?
One of the main reasons to upgrade to a double DIN receiver is the larger screen size. Double DIN units have a screen size of roughly 4 by 2 inches, while single DIN units max out around 2 by 2 inches. The larger double DIN screen provides more real estate for viewing maps, song information, climate controls, and other data. It also allows for a more intuitive, user-friendly interface with larger buttons and menus. According to this source, the expanded screen size enables “additional features, such as touchscreens, web connectivity, and video playback.”
In addition to the larger screen, double DIN receivers tend to offer more advanced features and functionality. As noted by this guide, double DIN units provide an “enhanced user interface” with “easier navigation and operation of the unit.” With the extra space, manufacturers can integrate higher-resolution screens, faster processors, capacitive touch sensors, and graphical interfaces. This allows for a more modern, responsive, and customizable experience compared to basic single DIN stereos.
Check Your Dashboard
The easiest way to determine if a double DIN stereo will fit your car is to check your existing head unit. Open up your dashboard and take a close look at the head unit currently installed. Note the size and shape of the opening where the stereo is positioned.
Most stock head units from the factory are either single DIN (about 2″ tall), double DIN (about 4″ tall), or an irregular custom size. If you currently have a double DIN sized stereo, then upgrading to a newer double DIN unit will be straightforward. Look for a rectangular opening that is approximately 4″ high by 7″ wide – this indicates it was designed for a full-sized double DIN.
According to lifewire.com, the most common head unit sizes measure roughly:
- 2” x 7” (50 x 180mm): Single DIN
- 4” x 7” (100 x 180mm): Double DIN
So if your current head unit already has these full double DIN dimensions, upgrading to a new double DIN stereo or media receiver will be a straightforward installation.
Consult Your Owner’s Manual
One of the best places to find information about whether a double DIN stereo will fit your car is in your owner’s manual. Most manuals will have a section that covers the factory stereo specs and installation. Here you can find details like the dimensions of the stereo opening, which radios were available from the manufacturer, and wiring diagrams.
For example, your manual may state that your car came equipped with a single DIN stereo measuring 7″ wide by 2″ tall. This indicates that a double DIN stereo (which measures roughly 7″ by 4″) likely won’t fit without modifying the dashboard. The factory wire colors and harness connectors will also be listed in the stereo section.
Checking the owner’s manual is useful even if you no longer have the factory stereo. It provides measurements and other specifics that pertain to your car’s model and year. Some manuals can be found online if you no longer have a physical copy. Referencing this information will help ensure you buy a stereo that’s fully compatible with your car.

Measure the Opening
The most important step is to accurately measure the height and width of your current car stereo opening. This will determine if a double DIN unit will physically fit into that space. You’ll need a tape measure for this.
To measure properly:
- Remove your current head unit if it’s still installed. This gives you full access to the opening.
- Measure the height from the top of the opening to the bottom. Double DIN units are about 4 inches in height, so there needs to be at least that much space.
- Measure the width across the entire opening left to right. Double DIN units are about 7 inches wide, so at minimum that much width is needed.
Be sure to measure carefully and precisely. Even a small difference in height or width may prevent a double DIN stereo from fitting correctly. Know the exact dimensions before making any purchase.
Account for Brackets
Many vehicles use mounting brackets that are secured to the dashboard behind the radio opening. These brackets add depth and allow the radio to be securely fastened in place. According to Mounting Depth For Head Units – Car Audio & Electrical, brackets can add up to several centimeters of depth that needs to be accounted for.
When measuring the depth of your dashboard opening, be sure to measure to the back of the brackets, not just to the dashboard surface. Adding just a couple centimeters of depth from brackets can make the difference between a radio fitting or not. You’ll need to know the full depth of the radio opening, including brackets, in order to ensure the double DIN stereo will fit properly.
Watch Out for Obstructions
Even if you have a double DIN opening, nearby components like the climate control panel, glove box, or steering column may partially block the installation of a double DIN stereo. Take measurements of the depth behind the dash opening and make sure there is sufficient room to install the stereo chassis without obstruction. Many vehicles have extra dashboard components right behind the stereo opening that can prevent a double DIN from sliding all the way in.
If something is obstructing the install, you may be able to modify the dash or extend the stereo chassis with a mounting bracket kit. But in some vehicles, there is simply not enough room. Check your owner’s manual for any special notes about double DIN compatibility or obstructions.
According to sources, “The most common installation challenges arise from a lack of dashboard depth for the new unit [1], so it’s important to measure behind the dash opening. Older vehicles especially may have climate controls or other components blocking the chassis from sliding in [2].”
Buy an Installation Kit
One of the easiest ways to ensure your new double DIN receiver will fit is to purchase a vehicle-specific installation kit. These kits come with all the necessary mounting brackets and wiring harnesses to install your new stereo. Models like Metra’s 95-8202 kit are designed to perfectly fit the dash opening and interior trim pieces of certain vehicle makes and model years.
Installation kits eliminate the need to modify your dash and also make wiring much simpler. Instead of having to manually connect speaker/power/antenna wires, the harness plugs right in. Just make sure to get a kit designed specifically for your vehicle, as they are not universal. With an installation kit, upgrading to double DIN is made much easier.
Consider Professional Installation
If DIY seems too difficult or intimidating, consider hiring a professional to install your new double DIN stereo. While a DIY installation can save money, it requires mechanical skills and stereo wiring knowledge. An experienced installer has the expertise to complete the job properly.
According to Yelp, the average cost to install a new car stereo ranges from $25-$100 (source). Factors affecting the cost include the shop’s hourly rate, the complexity of the install, and any additional parts or adapters needed. High-end auto shops and dealerships typically charge more than independent installers.
Though pricier, pro installation ensures the stereo is mounted securely and connected correctly. Professionals have the necessary tools and skills to install a double DIN cleanly and seamlessly in your dashboard. They can also integrate steering wheel controls, backup cameras, and other accessories into your new system.
An installer can advise which stereo suits your needs and budget too. Overall, pro installation may be worthwhile to save the headache and ensure your new stereo works perfectly.
