How much volume is the typical mouth capacity for fluids?

I’m about 5’10” tall and I weigh about 180 lbs.

I used a measuring cup to determine my oral capacity: it only took 1/8 cup, or about 30 ml, or 1 oz of water to fill my mouth.

I used a measuring cup as well. I was able to get 2 oz. but I think if someone else was pouring there might have been room for a little more. I have a small mouth. I use a child’s toothbrush and the dentist has to use the child’s tray when making impressions.

The only cup I have is a typical bar glass. I can easily hold that, and maybe a few more spoon fulls.

I tried the experiment 3 times. I drank from a water glass to fill my mouth. Then I spit it into a container on my Mettler balance.

Results. 86 ml, 98 ml, and 101 ml. I’d go with 100 ml as a good estimate.

@LuckyGuy -Is your mouth size typical?
Did your cheeks expand upon holding the liquid or was it measured with your average “sip”?

@lucillelucillelucille i did it with full cheeks. As in, how much could I spit if I were trying to put out a fire.
I have no idea if I am typical . I’m just one, high confidence data point.

@LuckyGuy-You know I am going to try this at some point. Lol!
I wonder if one’s palate/yak is usually proportional to the size of one’s head?
I did ask my dentist once if I had a big mouth. She said it was normal. Which was a wise choice as she had she fingers in my mouth. ;)

It may be a bit off topic, but I’m capable of swallowing a full ton of bullshit, from a supervisor.

I’ll make a half ton of lemonade, from a ton of lemons…
