No, 1/4" NPT isn't directly related to the diameter size. 1/4" NPT means the suggested size of the ID (inner diameter) for that thread type should be 1/4". But we we can get up to 1/2" ID out of a 1/4" NPT thread on a hose barb. When you buy the barbs select 1/4" NPT for the thread and whaterver you need of the ID of the barb. I think 1/2" ID is the biggest barb you can get with 1/4" NPT thread but I maybe wrong. You will have a hard time finding a 1/2" ID 1/4" NPT barb at Home Depot or any standard hardware store. Non of them around here carry anything over 3/8"ID. I found a 1/2" ID 1/4" NPT brass barb at NAPA autoparts of all places though. There is usually a hose place locally that carries such stuff aswell.
