I don't have this particular model anymore, wanted to replace it with the same one but thought I was getting a deal elsewhere and it was a different model. Sorry. But I also recommend this player. And they have some awesome holder that strap to the headrest on eBay that stretch a little if that's why you're asking for dimensions.
I am not sure. I have these to mu grand kids that are in Spain. I will say this it was a really good size and i was very impressed when i got it. I do have a pic of my grandbaby watching it while sittong on the couch do u think it would help to see that in comparison to everything around it?
