In brief: HUGE...

Bigger than a rain gutter..
. No - seriously it is small enough to slip through your nostril and go down the back of your throat into your esophagus.

In brief: 4 mm diameter

Esophageal manometry catheters are typically about 4 mm in diameter. They are long enough to travel from your nose, down the esophagus and into the stomach.
