measuring your sit bones

[macski]

Or you could go into your LBS - they will have some special memory foam that is designed to measure your sit bones as well as a size chart about what that means

I think you need a CT scan to do this right. I tried all of the suggestions mentioned above, and came up with this obscure measurement that matched a giraffe pelvis in the third trimester.

Maybe the bike shop is the best source.

Not all bike shops have the memory foam, or agree with it...

Don't agree with it -- meaning they don't think it gives an accurate or usable measurement?

I had great results with the yoga mat method, but that could just be luck.

If you got the same measurement again and again with all the suggested methods, maybe you just have sitbones that match a giraffe pelvis in the third trimester?

(mine are 170-190mm, and my hips themselves are not very wide. Sit bone width and hip width don't have much to do with each other)

ahhhh.. i wonder if painting my butt lightly with my daughter's washable paints, and then sitting on paper (a la stamping) will work...

Just wanted to ditto this - there really is very little correlation. I have narrow hips but quite wide sitbones. Yesterday I saw a rare pic of me biking taken from behind and it was actually visible, both the wide "seating" and the thigh bone that seemingly goes straight down.

Me too with the wide sit/narrow hip.
In fact, it feels like the distance between my sit bones is wider than the distance from either one of them to the outside world on the side.

How do you measure any other part of your body?

Use a cloth (or plastic) measure. Use one hand to hold the 0 end on one butt point and use the other hand to pinch the part of the tape over your other butt point.

Ditto this.

Hold a fabric measuring tape in one hand. Lie on your back and flip your legs into the air (kind of over your head but you don't need to go that far). Feel for the sit bones and then hold the tape at each bone point. Flip upright without letting go of the tape and read your measurement. Voila!

I never had luck with the sitting on gel-like things as I have way to much butt padding to get a good reading.

I was surprised at how narrow my sit bones were. I always thought that being a big bottomed girl meant that I had wide hips. Not so much (which explains why my thighs will ALWAYS touch no matter how thin I get!).

Ditto...all of it. Even when I was a size 2 (by modern sizing) in HS I wore the inner thighs of my jeans out fast. At the time I was all of 115#s at 5'3"ish.

I think making an impression is better than using a tape measure, because the sitbones aren't parallel to the sagittal plane. An impression gives you not only the inside and outside measurements, but the angle.

And I think the inner thigh rub has to do with Q-angle and adductor development. It's an issue for me and my moderately wide bones, too.

I am thinking the water base paint thing might work. I'm trying it this weekend.
