What is the general diameter of car cup holders?

[TessaLynn]

Generally, it is around 7CM to 8CM. Here is some relevant information: 1. Number of cup holders: Two to six cup holders, depending on the vehicle model. MPV models usually have six to eight cup holders, while five-seater SUV models typically have four cup holders. The usual locations are two behind the gear lever and two on the rear center armrest. However, when three people are seated in the rear, only the two front cup holders remain available. 2. Adjustment: Some models allow for adjustment, but most cup holders have a built-in function to secure the cup, eliminating the need for adjustment. Cup holders are used very frequently in vehicles, especially during long-distance driving or road trips, as they provide a convenient place to store drinks. This is particularly useful for containers that cannot be fully sealed.
