The whiskey cup has a diameter of about 8.5 cm and a "belly bulge" of about 1/2 cm in total.
And have an overall height of about 9.2 cm.
The glass has through the thick glass bottom a decent weight.
When I unpacked the glasses, I initially thought that the most of my "full-size" woman's hand (gloves size 7.5 and M) would be much too big and heavy.
So it is not. They are very good in the hand and are also filled to the brim to handle well.
We use these glasses as juice and water glasses.
