The oropharyngeal and nasopharyngeal airway are temporary airway devices. You need to select an appropriate size before inserting the airway.
Here is a mnemonic for the same!
Size of Oropharyngeal airway mnemonic: AA
Angle of mouth to angle of the mandible
Size of Nasopharyngeal airway mnemonic: TT
Tip of the nose to the tragus
If you get confused between which one is for which - AoA and TnT mnemonic.
That's all!
