What size is the Arduino barrel jack?
5.5mm
The barrel plug must have an outside diameter (OD) of 5.5mm or less. The operating voltage is recommended to be between 9V and 12V. The operating current is recommended to be 0.5A to 2A. Barrel connector length of 9.5mm or greater is sufficient.
How do you measure a DC Jack?
If you go into a shop you can compare and test the connector size, or if you are technically minded you can measure the size of the port and pin yourself. If you are measuring you need the diameter of the center pin for the (ID) and the inner diameter of the port (OD).
