I am sure I am missing this but can someone tell me the height of the 1.25 inch bumpers?

The 1.25" hemispheres are .625" tall.

Are they good for floor standing speaker?

I used the 2.5" Platinum Silicone Hemisphere Bumpers on a pair of floor standing speakers that weighed 68 lbs each and measured 41”H x 16”W x 13”D and it made the speakers way too wobbly and springy. It was too dangerous to use them under my speakers due to concerns over the speakers tipping over and falling. I wouldn’t recommend.

what size should I get for Kef R3 speakers?

Try to find out the size of the feet on the speaker and get a bumper to match. I’m guessing 3/4”. Nice speakers, enjoy!

Will these work as intended using these on 23 inches of a 32 inch center with quad woofers i cant use them further than 23 inches of the total of 32

Yes, they will work 23 inches apart on your 32 inch device.
