How much are tape-measurement methods thrown off by loose skin in the abdominal area?

I would expect it to affect measurements to some degree but I'm not sure what you're expecting to do about it.

Thanks for the response. It's more of a good piece of information to know than anything else.

I figure I've got two choices if I want more accurate measurements: Buy calipers and use the caliper measurements I can do by myself (no one to help with the caliper) or paying $50 for a Dexa scan at a local clinic to see the degree of difference between it and the tape measurement method.

If you can get a DEXA scan for only $50, the other measurement methods are pretty much a waste of your time (and money).

I was leaning calipers because the $50 only covers one DEXA scan while I'd have the calipers forever for less than $50. I didn't know $50 was cheap for a DEXA scan. I just assumed that was kinda pricy.

I realize this isn't very scientific, but my idea with the DEXA scan was to do my usual tape measurements the morning of the scan and then have the scan done. I'd then compare the scan to the measurements and come up with a differential - if the scan said 15 percent and the measurements said 17 percent, for example, then I'd just assume a 2 point differential on future measurements.

The second site still seems to be broken.
The first site listed me as 17.14% (no way, no how)
The third site said 29.8% (much better. I'm probably around 31, 32.)

Going only by this experience, I'd say that unless they're fit or built like an apple, women will probably get a better tape-measure estimation with calculators that ask for more than just a waist measurement.

The calculator in the second link is broken, but this site does the same thing (US Navy Circumference method):

Thanks for the link. I like that it posts the formulas used right on the page.

and DEXA can provide enough variability to make it not much use as well...

No form of measurment is perfect

DEXA measurement of bodyfat is based on equations developed on people who are not you

Your body water can vary

the food in your belly can vary

teh type of dexa and/or their software can vary

teh operator can vary

the day definately varies

all of the above can influence what result comes out the other side.

even same day, same operator, same machine can have variation

woot for DEXA
