We hear from many people who are surprised that our Sizing Quiz recommends the Small Set size instead of the Large Set they expected. Our quiz has been refined over many years and we find that it's highly accurate most of the time.
We recommend following the Sizing Quiz results for the Small Set because it's very likely to have the right size even though you've been sized larger in other flange brands. And due to elasticity issues, what looks like or even measures as a certain size often turns out to be different when it's in a flange using vacuum. But if it turns out you need a different size than what's in your set, we have a Sizing Guarantee (domestic orders only) with our three size Sets to send you any other size at no cost.
