Why do all sitcoms have the same layout in their apartments?

Ease of filming. :)
And it looks just lived in enough.

Because sitcoms are typically fixed camera and in front of an audience. They have to be seen at all times.

Yup, camera placement. Sitcoms are a three-camera set-up. At least Frasier‘s apartment set was interesting, with the angles of the sofa and the off-center terrace door placement.

There’s a deeper psychology to it too. If people see something they recognize and are comfortable with, they are much more prone to laugh then if the set is something odd or out-of-placeish. (i don’t know .. i just made that up just now… it’s probably total crap)

It would be just a logistical and timing nightmare (and it would cost a lot more) to shoot a studio audience-based sitcom or sketch show with cameramen running around, but it is what’s familiar.

Desi Arnaz came up with the filmed 3-camera setup as used today for I Love Lucy. If you find clips of TV shows from the late 40s to ca. 1951, they look really bad to our eyes, because they were shot live with one camera going left to right and aimed from the waist up. The only way to record a show was to aim a film camera at a TV. There were no decent commercial video cameras or VCRs until the late 50s. I Love Lucy looks “normal” to us – that show started the familiar “living room couch in front-kitchen on the right-bedroom on the left-front door in the back” set that we know today. They were the innovators of the sitcom as we know it.

You notice that about Frazier as well, @aprilsimnel . I thought that set was groundbreaking, to use that overused adj.

A lot of the “couch facing the camera” shows actually have a TV as a part of the set, facing the couch. We usually see only the top and back of the TV (like on Seinfeld).

It’s like we are the TV, looking into their house. Which is really kind of spooky.

It’s the same apartment. They just change the name and the city.
Actually the couch is over to the left a little bit and you forgot the curtains on the kitchen door.:)

@SeventhSense It’s also the same actors, just wearing costumes and make-up. Internationally, their voices are dubbed.

Star Wars Dub———-> LOL

@SeventhSense——- dubbing comes to puppet sitcoms too – strong language, parental guidance -
