What size is the butt on this?

Hi,
I was given a pool cue by a family member, with no information.
I just measured the butt in order to find the proper size cue holder, but cannot decipher a Vernier Caliper tool.
Can someone please help? I'm attaching a photo of the measurement directly from the caliper.
The Vernier Caliper brand is Performance Tool (a cheap stainless steel one) and a 5 in./120mm capacity with 0.1 mm and 128th in. vernier graduations.
Thank you so much for your time and help!

Cue holder as in a wall mounted rack to hold 10 sticks? If so, they are all universal and fit any pool cue.

Your vernier is reading 31.8mm. Although, the vernier scale is either misaligned by .1 to .2mm, or there is parallax in your picture. That is 1.25 inches, which is standard for a cue butt cap.

You are correct, I didn't loot at the other lines that line up on the 8 ;)
 
As a youtube video will tell you, on the slider there is a series of 10 marks, and the left most mark is considered 0. You look to the left of the 0 mark to find the closest whole number on the scale above, which is 31mm. Then you look at the 10 marks on the slider and find out which mark lines up perfectly with one of the marks on the scale above it. In your image, it looks like the 8th (or 9th) mark on the slider lines up perfectly with a mark above it. Because your calipers have "0.1 mm vernier graduations", you multiply the 8th mark by 0.1mm = 0.8 mm making the total measurement: 31mm + 0.8mm = 31.8 mm.

To summarize, the left most mark on the slider (the 0 mark) is used to find the whole number of millimeters in the measurement, then figuring out which mark on the slider perfectly lines up with a mark on the scale above is used to determine the fractional part of a millimeter for the measurement.

It's a dual-scale vernier. The top is inches and shows very close to 1.25". The bottom shows 31.8. 1.25" = 31.75mm. .05mm is 0.002". Suffice to say, the cue is close enough to 1.25" that nobody would notice the difference.
