Whatâs the narrowest door you can fit a Baby Jogger City Mini GT Double through? The City Mini GT Double is one of the narrowest high-end side by side strollers on the market; at 29.75â³ inches wide, it is capable of fitting through doors just under 30â³ wide, which is smaller than the standard door size.
