analog newbie question/vinyl weight

has anyone taken measurements of 120,150,180 and 200 weighted lps in inches curious as to what those measurements really are.

Mine are all 12" across, plus or minus a twidge. ;-)

Yes Doug i guess i m being just a little to anal on the scientific end instead of the end that counts
let the force be with you Luke.

Kind of tough to measure with most LPs having that ridge at the beginning of the LP.

I'm too cheap to buy one.

outside micrometer

Yea Dan ed i understand. I guess you know what i m getting at that old subject VTA with different weighted records. I did buy a 5X lighted magnifying glass to get a better look at the position of my stylus.

We all know when dialed in VTA can make the difference between very nice sound and most excellent sound.
