It's about 1.5 inches at the opening and around two inches at its widest point, whereas my other standard shoot glasses are around two inches at the opening and get smaller as you near the base.

I have not measured but I believe the opening is roughly 15 inches. I have a 55 lb goldendoodle and she goes in and out very easily. Hope this helps.

Looks like the widest it opens is about 3.75".... I would say 3.5" to be safe.

4 inches diameter at solid flat base. 4.45 inches diameter at the opening. A good solid item.

Opening is approx. 3-1/2". Height about 6". I use it to hold a sport bottle around my wife's neck. She's disabled and can't hold on for long.

The opening is 4 1/2 inches in diameter. It is a good size opening, I have large hands and have no problem getting them into the jar. Hope this helps......

The opening is probably 5 to 5.5 inches. A Moen one handle fixture fits over it and that measures about 6 1/2 inches.

The interior opening is 3 inches. The total diameter is 3 1/2 inches. I bought them for my storage jars with the metal clamp closures. These rings are a little big, but they will work.

I am not sure of the exact dimension... I believe it goes to about 5/16"+ fully open. This is a GREAT product!

The opening is exactly 1.5 inches in diameter. I was able to easily fit my standard umbrella pole into it.

The actual opening is 2 1/4 inches wide. The lid fits into an opening that is 3 1/2 inches wide. I hope this helps.
