Try using your hands. (I think it's more accurate, anyway.)

Sit on your hands, and feel for the two bones of your butt. They feel like elbows poking down into your hands.

Put the tip of your index fingers right under the part of the bones that is pushing hardest into the chair. (squish the very tip of your fingers between the chair and your sitbones)

Lift your butt from the chair leaving your hands on the chair, and have your assistant measure the distance between your fingertips. This is pretty much your center-to-center.

Then put your fingertips against the outsides of the bones. Push them right into the bones so they are on the outside of the bones. Lift your butt from the chair and have an assistant measure the distance between your fingertips. This is pretty much your outside.

Some people have sitbones that angle a lot from front to back. The sits are heavy thickened portions of the rami and can have unique personalities of their own. You can measure again on the forward part of the heavy "elbow" bit if you can feel that yours have a definite angle. The forward portion of the heavy thick part of the bone is what your weight rests on more when you are in a more aero position. DON'T measure the thin blade like portion that is in your crotch, that is the rami and you do not want a saddle there. Measure from your backside.

Repeat your measurements a few times, average them out if you want.

You can also get these measurements by lying on your back with your knees to your chest holding a measuring tape and poking around for landmarks.
