Does the iPhone 6s Plus have the same dimensions as its predecessor the iPhone 6 Plus?

I found a case on Amazon that is a rose gold color (to go with the new color option of the phone) but IIm not sure if I can buy it and make it fit my 6 Plus. I don't want to get the new phone yet either but like the color of the case.

Not exactly, close though. So some cases may work, some may not.

Reason for the difference, having to put in 3D Touch.

The 6s plus is a bit thicker, your case won't work
