DIN is a standard car stereo size. Typically all car stereos that you could replace with any other car stereo was a single DIN. They are wide, not very high and quite deep into the dashboard. Typically that used to have a tape player, then later versions had a CD player. These were all DIN size.

Double DIN

Double DIN is the size of 2xDIN. When stacked in top of each other you get the same width, same depth, but twice the height of a single DIN.

The same features apply to Double DIN as single DIN, but some cars could take two single DIN, like a CD and CD autochanger or a single Double DIN stereo.

Double DIN android headunit

The meaning behind the phrase ‘double DIN android headunit’ should now be evident.

A double DIN android headunit you can have a maximum screen size of 7″ diagonal and stay within the constraints of the double DIN size. This is a good size to still read the screen icons from the drivers seat. But the screen sizes are not limited to the DIN size as found in all the 10″ screens right up to the huge tesla stye screens, like this joying. There are many single DIN android headunits that have relatively large screens. You can see the body size and screen size can be independent of each other.

Old format

The Double DIN can be considered an old format. This is due to most car manufacturers moving away from a double or single DIN space for the car stereo. Modern cars generally have custom fit car stereos, one that will only fit a particular manufacturer, like the ford brand. Even if a space looks like it could be a double DIN, it may not be. Conversely the front of the stereo may be hiding a Double DIN space behind it.

What’s fitted?

Measuring your existing stereo front can help you identify if it is a double DIN, single DIN or custom fit.
The DIN headunits are rectangular, so if your existing car stereo is not rectangular, it won’t be a DIN.

The dimensions of single DIN are 180mm wide by 50mm high and the dimensions of the Double DIN are the same 180mm wide but double the height of a single DIN at 100.3mm.

If your existing stereo or the car radio aperture measure very close to the rectangular DIN sizes above, it can be assumed that a single or double DIN android headunit will fit in the space.


The depth is the distance that the stereo disappears into the dashboard. There is no standard for this with a single DIN or double DIN android headunit. Typically they can reach to 100mm from front to back, others can be over 120mm from to back.. There is also the consideration of the rear fitting cables. These plugs add to the depth required. It needs a tape measure to ensure there is adequate depth to install the android headunit in the dashboard. Check with the manufacturer of the headunit for the dimensions required.


2DIN is the same as Double DIN. it may be shown as 2DIN to save space on the sales page. Similarly 1DIN is the same as single DIN.
