Cup holder diameter

Here is a first-world problem... what is the diameter at the bottom of the central console cup holder? A Google search says, "Specific physical dimensions (such as exact diameter, depth, or height) for the factory cup holder of the 6th-generation Honda Prelude (BF1, 2025–2026) are not officially published by Honda in standard specification sheets."

As a "senior" citizen, we are not as aware of our thirst, so getting a water bottle might be useful. But which ones fit since there are no cup holder & water bottle international standards (showing my computing OCD side)? I cut 2 wooden skewers to length, one 75 cm long and the other 78 cm, and drop them horizontally into the cup holder. The 75 cm one fitted perfectly at the bottom.

...can understand the intention, but still trying to imagine what you have done with these two 75cm (!) and 78cm skewers in your car ....

There is a aftermarket silicone insert for the cup holder , no dimensions listed, but it may be reducing noise and improving fitting...

Hi @rolox using the two skewers was simply a way to find out the *exact* diameter measurement of the Prelude BF1 cup holder. The skewers do not stay in the cup holder, I removed them afterwards! Now that I know that the diameter is 75 cm, I can confidently go buy a water bottle that is 75 cm wide and know that it will fit perfectly. If I had bought a 78 (or larger) cm wide bottle instead, it would not fit properly... hope that makes sense.
