How to measure a seal

Rod seal: measure the rod diameter (d), the groove diameter in the gland (D) and the groove width (H).
Piston seal: measure the cylinder bore (D), the groove bottom diameter on the piston (d) and the groove width (H).
O-ring: measure the inner diameter (d) and the cord thickness (H). A used seal may have shrunk or swollen: preferably measure the groove and use the tolerance.
